在分析三，我们已经分析出jsp页面如何通过struts2的标签与action配合，将数据在表示层传递(set/get),并且把主要的开始流程给分析完了。这里我们将前台的主要请求大致分析一下：从导航部分开始，对于社区首页in.bbscs我们已经讲过，它这里只不过是将框架的target=mainForm以便从任何位置转到首页!进入个人中心，点击修改签名，触发了signSet.bbscs:
<action name="signSet" class="signSetAction">
   <interceptor-ref name="mainUserAuthInterceptorStack"></interceptor-ref>//用户权限！
   <result name="success">/WEB-INF/jsp/signSet.jsp</result>
   <result name="input">/WEB-INF/jsp/signEdit.jsp</result>
  </action>
-->
注意到BaseMainAction:
public String execute() {
  try {
   return this.executeMethod(this.getAction());
  } catch (Exception e) {
   logger.error(e);
   this.addActionError(this.getText("error.msg"));
   return ERROR;
  }
}
而在BaseAction:private String action = "index";
public String index() {
  String[] userSign = new String[3];
  userSign[0] = this.getUserSession().getSignDetail()[0];//从UserSession的SignDetail数组中把三个对象拿出来！
  userSign[1] = this.getUserSession().getSignDetail()[1];
  userSign[2] = this.getUserSession().getSignDetail()[2];
  userSign = BBSCSUtil.filterUserSign(userSign, this.getSysConfig().isSignUseHtml(), this.getSysConfig()
    .isSignUseUBB(), this.getSysConfig().isSignUseSmile());
  this.setUserSign0(userSign[0]);
  this.setUserSign1(userSign[1]);
  this.setUserSign2(userSign[2]);
  return SUCCESS;
}
我们看一下signSet:
<strong><a href="javascript:;" onclick="loadSignEditPage(Ɔ');"><s:text name="signset.sign"/>A</a></strong>
<div id="signDiv0" class="signDivOff" onclick="loadSignEditPage(Ɔ');" onmouseover="over(this);" onmouseout="out(this);"><s:property value="%{userSign0}" escape="false"/></div>
需要注意到底部有个div:
  <tr>
          <td colspan="2">
            <div id="signDetailChange"></div>
          </td>
        </tr>
我们来看loadSignEditPage(signID):
function loadSignEditPage(signID) {
Element.show("signDetailChange");
$('signDetailChange').innerHTML = pageLoading;//在jsMsg.jsp中,var pageLoading = "<s:text name="js.pageLoading"/>";
var url = getActionMappingURL("/signSet");
var pars = "action=edit&ajax=shtml&signID=" + signID;

edit: function() {
    showExeMsg();
    var url = getActionMappingURL("/signSet");
    var pars = "action=editdo&ajax=xml&signID="+this.signID+"&signDetail="+encodeURIComponent($('signDetail').value);//将文本字符串编码为一个统一资源标识符 (URI) 的一个有效组件
    var myAjax = new Ajax.Request(url, {method: 'post', parameters: pars, onComplete: this.editCompleted.bind(this)});
},

editCompleted: function(res) {
    resText = res.responseText;
var jsonMsgObj = new JsonMsgObj(resText);
var codeid = jsonMsgObj.getCodeid();
    hiddenExeMsg();
    alert(jsonMsgObj.getMessage());//提示信息
    if (codeid == "0") {
      $('signDiv'+this.signID).innerHTML = jsonMsgObj.getText();//写入内容
      closeSignEditPage();//关闭编辑框!
    }
}
};
这里又用致函一个函数：
function hiddenExeMsg() {
var loade = document.getElementById("exeingdiv");
if (loade != null) {
    loade.style.display = "none";
}
}
OK!我们进入SignSet.java的editdo方法中:
public String editdo() {
  if (BBSCSUtil.getSysCharsetStrLength(this.getSignDetail()) > this.getSysConfig().getSignMaxLen()) { // 签名超过指定长度
/**
public static int getSysCharsetStrLength(String txt) {
  try {
   return txt.getBytes(Constant.CHARSET).length;
  } catch (UnsupportedEncodingException ex) {
   return txt.length();
  }
}
*/
   this.getAjaxMessagesJson().setMessage(
     "E_USER_SIGN_TOOLONG",
     this.getText("error.sign.toolong", new String[] { String.valueOf(this.getSysConfig()
       .getSignMaxLen()) }));
   return RESULT_AJAXJSON;
  }
  UserInfo ui = this.getUserService().findUserInfoById(this.getUserSession().getId());
  if (ui != null) {
   String signDetail = "";
   if (StringUtils.isBlank(this.getSignDetail())) { // 签名为空，设为默认签名
    signDetail = this.getText("bbscs.userdefaultsign");//系统用的资源
    switch (this.getSignID()) {
    case 0:
     ui.setSignDetail0(signDetail);
     break;
    case 1:
     ui.setSignDetail1(signDetail);
     break;
    case 2:
     ui.setSignDetail2(signDetail);
     break;
    }
   } else {
    signDetail = this.getSysConfig().bestrowScreen(this.getSignDetail()); // 过滤敏感词

    switch (this.getSignID()) {
    case 0:
     ui.setSignDetail0(signDetail);
     break;
    case 1:
     ui.setSignDetail1(signDetail);
     break;
    case 2:
     ui.setSignDetail2(signDetail);
     break;
    }
   }
   try {
    ui = this.getUserService().saveUserInfo(ui);
    this.getUserSession().getSignDetail()[this.getSignID()] = signDetail;
    signDetail = BBSCSUtil.filterText(signDetail, this.getSysConfig().isSignUseHtml(), this.getSysConfig()
      .isSignUseUBB(), this.getSysConfig().isSignUseSmile());
    this.getAjaxMessagesJson().setMessage("0", this.getText("sign.edit.ok"), signDetail);//设置message提示信息！
   } catch (BbscsException ex) {
    logger.error(ex);
    this.getAjaxMessagesJson().setMessage("E_USER_SIGN_ERROR", this.getText("error.sign.edit"));
   }
  }
  return RESULT_AJAXJSON;
}
这里的关键是对文本信息的过滤(BBSCSUtil)：
public String bestrowScreen(String txt) { //将系统不允许出现的字词换成**
  if (StringUtils.isNotBlank(this.getScreenWord())) {
   String[] words = this.getScreenWord().split(";");
   for (int i = 0; i < words.length; i++) {
    txt = txt.replaceAll(words[i], this.getBestrowScreen());
   }
  }
  return txt;
}
public static String filterText(String sign, boolean useHTML, boolean useUBB, boolean useSmile) {
  if (!useHTML) { //默认1
   sign = TextUtils.htmlEncode(sign);//转意字符！这里用的是com.opensymphony.xwork2.util工具类！
  }
  if (useUBB) {//0
   sign = getUBB2HTML(sign);
  }
  if (useSmile) {//1
   sign = replaceSmile(sign);
  }
  sign = sign.replaceAll(" ", "<BR/>");
  sign = filterScript(sign);
  return sign;
}
-->
public static String replaceSmile(String txt) {
  if (txt != null) {
   return txt.replaceAll("\{(\d{1,2})\}", "<img src="images/smile/$1.gif" alt="smile"/>");//正则表达式!
  } else {
   return "";
  }
}
public static String filterScript(String txt) {
  return txt.replaceAll("[Ss][Cc][Rr][Ii][Pp][Tt]", "s.c.r.i.p.t");
}
public static String getUBB2HTML(String txt) {//UBB实现
  if (txt != null) {
   AutoFilter af = new AutoFilter(txt);
   txt = af.getFilteredStr();
  }
  return txt;
}
AutoFilter继承了RegexFilter...而RegexFilter实现了Filter接口:
public interface Filter {
public abstract String getFilteredStr();//我们便通过这个方法得到返回的结果的！
}
在AutoFilter的构造方法中有许多regex的reStr属性(在RegexFilter定义为protected)也有this.doFiltration();方法，我们看super(txt)方法：
protected RegexFilter(String source) {
    this.source = source;
    this.tempSource = source;
}
而每次代换doFiltration():
protected void doFiltration() {
    this.applyFilter();
    this.tempSource = filter.getFilteredStr();
}
用了 protected void applyFilter() {
    FilterBuilder builder = new RegFilterBuilder(regex, rpStr, tempSource);//注意这里用的是tempSource!
    FilterDirector direct = new FilterDirector(builder);//导演FilterDirector生成FilterBuilder的各种实现
    direct.construct();

    this.filter = builder.getFilter();
}
我们看真正的执行者：RegFilterBuilder,实现了FilterBuilder中的所有方法:
public interface FilterBuilder {
public abstract void buildFilter();
public abstract Filter getFilter();
}
它使用的是JDK中的正则类：
import java.util.regex.Matcher;
import java.util.regex.Pattern;
public RegFilterBuilder(String regex, String rpStr, String source) {
    super();
    this.regex = regex;
    this.rpStr = rpStr;
    this.source = source;
}
public void buildFilter() { //关键的方法！需重点理解之！请参考资料：http://wcjok.bokee.com/4293762.html
    if (this.regex == null) {
      return;
    }
    Pattern p = Pattern.compile(regex, 2);
    Matcher matcher = p.matcher(this.source);
    StringBuffer sb = new StringBuffer();
    String tempString = rpStr;
    int rpL = rpStr.split("\$[0-9]+").length;
    while (matcher.find()) {
      for (int i = 0; (i < rpL) && (i < matcher.groupCount()); i++) {
        tempString = tempString.replaceAll("\$" + i, matcher.group(i));
      }
      matcher.appendReplacement(sb, tempString);
    }
    matcher.appendTail(sb);
    this.result = sb.toString();
}
public Filter getFilter() { //回调一个刚过滤的中间结果！
    return (new RegexFilter() {
      public String getFilteredStr() {
        return result;
      }
    });
当然我们还有一个FilterDirector!由它管理FilterBuilder对象和它的buildFilter方法!
public FilterDirector(FilterBuilder builder) {
    this.builder = builder;
}
public void construct() {
    builder.buildFilter();
}
而getFilter则仍由Builder自己来返回this.filter = builder.getFilter();
接下来，我们分析nickNameSet.bbscs,它很简单:
<action name="nickNameSet" class="nickNameSetAction">
   <interceptor-ref name="mainUserAuthInterceptorStack"></interceptor-ref>
   <result name="input">/WEB-INF/jsp/nickNameSet.jsp</result>
  </action>
public String index() {
  this.setAction("edit");
  this.setNickName(this.getUserSession().getNickName());
  return INPUT;
}
<s:form action="nickNameSet">
      <s:hidden name="action"></s:hidden>
      <tr>
        <td><s:text name="nickset.title"/></td>
        <td>
          <s:textfield id="nickName" name="nickName" cssClass="input2" size="40" maxlength="20" onkeypress="return handleEnter(this, event);"></s:textfield>//已经被填充!
        </td>
....
我们提交editNickName():
function editNickName() {
var url = getActionMappingURL("/nickNameSet");
var pars = "action=edit&ajax=xml&nickName="+encodeURIComponent($('nickName').value);
var myAjax = new Ajax.Request(url, {method: 'post', parameters: pars, onComplete: editNickNameOK});
}

function editUserConfigOK(res) {
resText = res.responseText;
var jsonMsgObj = new JsonMsgObj(resText);
var codeid = jsonMsgObj.getCodeid();
hiddenExeMsg();
alert(jsonMsgObj.getMessage());
}
好的，我们回到UserConfigSet.java:
public String edit() {
  UserInfo ui = this.getUserService().findUserInfoById(this.getUserSession().getId());
  if (ui != null) {
   ui.setAcceptFriend(this.boolean2int(this.getAcceptFriend()));//action自动获得值！注意现在是boolean2int!
   ui.setForumPerNum(this.getForumPerNum());
   ui.setForumViewMode(this.getForumViewMode());
   ui.setHiddenLogin(this.boolean2int(this.getHiddenLogin()));
   ui.setPostPerNum(this.getPostPerNum());
   ui.setReceiveNote(this.boolean2int(this.getReceiveNote()));
   ui.setTimeZone(this.getTimeZone());
   ui.setEditType(this.getEditType());

   try {
    ui = this.getUserService().saveUserInfo(ui);
    this.getUserCookie().addCookies(ui);//加入cookie中!
    this.getAjaxMessagesJson().setMessage("0", this.getText("userconfig.set.ok"));
   } catch (BbscsException ex) {
    logger.error(ex);
    this.getAjaxMessagesJson().setMessage("E_USERCONFIG_EDITFAILED",
      this.getText("error.userconfig.seterror"));
   }
   return RESULT_AJAXJSON;
  } else {
   this.getAjaxMessagesJson().setMessage("E_USER_NOEXIST", this.getText("error.user.noexist"));
   return RESULT_AJAXJSON;
  }
}
我们看friendSet.bbscs!
<action name="friendSet" class="friendSetAction">
   <interceptor-ref name="mainUserAuthInterceptorStack"></interceptor-ref>
   <result name="success">/WEB-INF/jsp/friendSet.jsp</result>
   <result name="flist">/WEB-INF/jsp/friendList.jsp</result>
   <result name="input">/WEB-INF/jsp/friendAdd.jsp</result>
  </action>
它有friendList,freindName,id,isBlack,friendComment等属性.
public String index() {
  return SUCCESS;
}
直接进入friendSet.jsp:
<body onload="loadFriendList();"> //<script type="text/javascript" src="js/friend.js"></script>
<div id="f_bg">
<div id="f_tabs">
    <ul>
      <li id="tab1" class="f_tabClass1"><a href="javascript:;" onclick="loadFriendList();"><s:text name="friend.fuser"/></a></li>
      <li id="tab2" class="f_tabClass2"><a href="javascript:;" onclick="loadBlackUserList();"><s:text name="friend.blackuser"/></a></li>
    </ul>
</div>
</div>
<div id="f_main">
<div id="friendlist"></div>//一个div
<div id="addfriend"></div>//另一个div,用于ajax
</div>
</body>
我们在js/friend.js中找到相应的js:
function loadFriendList() { //含一些初始化工作！
hiddenElement("addfriend");//隐藏addfriend这个div
$('tab1').className = "f_tabClass1";//着色！
$('tab2').className = "f_tabClass2";
$('friendlist').innerHTML = pageLoading;//加载中！
var url = getActionMappingURL("/friendSet");
var pars = "action=flist&ajax=shtml&isBlack=0";
var myAjax = new Ajax.Updater("friendlist", url, {method: 'get', parameters: pars});
}
-->
public String flist() {
  this.setFriendList(this.getFriendService().findFriends(this.getUserSession().getId(), this.getIsBlack()));//找到他们！
  return "flist";
}
这里首先用了:
<%
request.setAttribute("decorator", "none");
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy server
%>
<s:iterator id="f" value="%{friendList}"> //下面是用于显示的遍历！
    <tr>
      <td>
        <s:property value="#f.friendName"/>
      </td>
      <td>
        <s:property value="#f.friendComment"/>
      </td>
      <td><a href="javascript:;" onclick="friendDel('<s:property value="#f.id"/>','<s:property value="#f.isBlack"/>');"><s:text name="bbscs.del"/></a></td>
    </tr>
</s:iterator>
下面的是这个增加按钮的显示：
<s:if test="%{isBlack==0}">
      <a href="javascript:;" onclick="friendNew(Ɔ');"><s:text name="friend.add"/></a>
      </s:if>
      <s:if test="%{isBlack==1}">
      <a href="javascript:;" onclick="friendNew(Ƈ');"><s:text name="friend.addblack"/></a>
      </s:if>
当我们点击黑名单时,调用JS：
function loadBlackUserList() {
hiddenElement("addfriend");
$('tab1').className = "f_tabClass2";
$('tab2').className = "f_tabClass1";
$('friendlist').innerHTML = pageLoading;
var url = getActionMappingURL("/friendSet");
var pars = "action=flist&ajax=shtml&isBlack=1";
var myAjax = new Ajax.Updater("friendlist", url, {method: 'get', parameters: pars});
}
如果有好友，我们可以删除之..
function friendDel(id,isBlack) {
var del = confirm(confirm_del); //需要确认一下！
if (del) {
    var oFriendDelAjax = new FriendDelAjax(id,isBlack);
    oFriendDelAjax.delFriend();
}
else {
    return false;
}
}
看下面的代码:
var FriendDelAjax = Class.create();
FriendDelAjax.prototype = {
initialize: function(id,isBlack) {
    this.id = id;
    this.isBlack = isBlack;
},

delFriend: function() {
    showExeMsg();
    var url = getActionMappingURL("/friendSet");
    var pars = "action=del&ajax=xml&id=" + this.id;
    var myAjax = new Ajax.Request(url, {method: 'get', parameters: pars, onComplete: this.delFriendCompleted.bind(this)});
},
delFriendCompleted: function(res) {
    resText = res.responseText;
var jsonMsgObj = new JsonMsgObj(resText);
var codeid = jsonMsgObj.getCodeid();
    hiddenExeMsg();
    alert(jsonMsgObj.getMessage());
    if (codeid == "0") {
      if (this.isBlack == "0") {
        loadFriendList(); //根据isBlack重新加载好友列表！
      }
      if (this.isBlack == "1") {
        loadBlackUserList();
      }
    }
}
};
我们看JAVA代码片断：
Friend f = this.getFriendService().findFriendByID(this.getId(), this.getUserSession().getId());//找到friend!
  if (f != null) {
   UserInfo ui = this.getUserService().findUserInfoById(f.getFriendID());
   int isBlack = f.getIsBlack();
   try {
    this.getFriendService().removeFriend(f);//去之
    if (ui != null) {
     if (isBlack == 0) {//数据库的记录是好友！
      ui.setUserKnow(ui.getUserKnow() - 1); // 减少用户人缘系数
      this.getUserService().saveUserInfo(ui);
     } else {
      ui.setUserKnow(ui.getUserKnow() + 1); // 增加用户人缘系数
      this.getUserService().saveUserInfo(ui);
     }
    }
当我们点击增加时：出现div为addfriend的内容显示，下面是一个特别之处：
   <td width="82%">
        <s:textfield id="friendName" name="friendName" cssClass="input2" size="40" maxlength="20" onkeypress="return handleEnter(this, event);"></s:textfield>
      </td>
-->
function handleEnter (field, event) {
var keyCode = event.keyCode ? event.keyCode : event.which ? event.which : event.charCode;//firefox2.0中不支持 window.event.keyCode!
if (keyCode == 13) { //回车键(也就相当于<br>没有)
    return false;
}
return true;
}
当提交时：
function friendAdd() {
var isBlack = $('isBlack').value;
var oFriendAddAjax = new FriendAddAjax(isBlack);
oFriendAddAjax.addFriend();
}
ar FriendAddAjax = Class.create();

FriendAddAjax.prototype = {
initialize: function(isBlack) {
this.isBlack = isBlack;
},

addFriend: function() {
    showExeMsg();
    var url = getActionMappingURL("/friendSet");
    var pars = "action=addsave&ajax=xml&friendName="+$('friendName').value+"&friendComment="
    + encodeURIComponent($('friendComment').value) + "&isBlack="+this.isBlack //带全参数哦！
    var myAjax = new Ajax.Request(url, {method: 'post', parameters: pars, onComplete: this.addFriendCompleted.bind(this)});
},

addFriendCompleted: function(res) {

resText = res.responseText;
var jsonMsgObj = new JsonMsgObj(resText);
var codeid = jsonMsgObj.getCodeid();

    hiddenExeMsg();
    alert(jsonMsgObj.getMessage());
    if (codeid == "0") {
      closeFriendNewPage();
      if (this.isBlack == "0") {
        loadFriendList();
      }
      if (this.isBlack == "1") {
        loadBlackUserList();
      }
    }
}
};
对于FriendSet.java的addsave方法:
f = this.getFriendFactory().getInstance(this.getUserSession().getId());
产生一个freind实例用于填充之.
f = this.getFriendService().saveFriend(f); // 保存用户
   this.getFriendService().friendIDsToFile(this.getUserSession().getId()); // 将用户列表写入文件
   if (this.getIsBlack() == 0) { // 添加好友情况下
    ui.setUserKnow(ui.getUserKnow() + 1); // 增加用户人缘系数
    this.getUserService().saveUserInfo(ui);
   } else {
    ui.setUserKnow(ui.getUserKnow() - 1); // 减少用户人缘系数
    this.getUserService().saveUserInfo(ui);
   }
好的，我们看note.bbscs:
<action name="note" class="noteAction">
   <interceptor-ref name="mainUserAuthInterceptorStack"></interceptor-ref>
   <interceptor-ref name="requestBasePathInterceptor"></interceptor-ref>
   <result name="success">/WEB-INF/jsp/note.jsp</result>
   <result name="noteInbox">/WEB-INF/jsp/noteInbox.jsp</result>
   <result name="noteOutbox">/WEB-INF/jsp/noteOutbox.jsp</result>
   <result name="input">/WEB-INF/jsp/noteSend.jsp</result>
   <result name="noteReadInbox">/WEB-INF/jsp/noteReadInbox.jsp</result>
  </action>
不过这里用到了requestBasePathInterceptor,注意他对应的是NoteAction.java:有fromID,id,ids,noteContext,noteTitle,toID,toUserName,needRe,pageList等属性.
public String index() {
  return SUCCESS;
}
看note.jsp:<body onload="loadNoteInbox();">它有了js/note.js中的一些函数:
function loadNoteInbox() {
$('noteListDiv').innerHTML = pageLoadingCenter;//noteListDiv是一个空的div,var pageLoadingCenter = "<div align="center"><s:text name="js.pageLoading"/></div>";
var urls = getActionMappingURL("/note");
var pars = "action=inbox&ajax=shtml";
var myAjax = new Ajax.Updater("noteListDiv", urls, {method: 'get', parameters: pars});
showInboxNum();
showOutboxNum();
}
-->
function showInboxNum() {

var url = getActionMappingURL("/note");
var pars = "action=innum&ajax=xml";

var myAjax = new Ajax.Request(url, {method: 'get', parameters: pars, onComplete: showInboxNumComplete});

}

function showInboxNumComplete(res) {
var resText = res.responseText;
var jsonMsgObj = new JsonMsgObj(resText);

$('inboxNumDiv').innerHTML = jsonMsgObj.getText();
}

function showOutboxNum() {

var url = getActionMappingURL("/note");
var pars = "action=outnum&ajax=xml";

var myAjax = new Ajax.Request(url, {method: 'get', parameters: pars, onComplete: showOutboxNumComplete});
}

                        <tr>
                          <td width="15%"><s:text name="note.tousername"/>:</td>
                          <td width="85%"><input name="toUserName" type="text" value="<s:property value="#note.fromUserName"/>" readonly="readonly" class="input2" size="40" /></td>
                        </tr>
                        <tr>
                          <td width="15%"><s:text name="note.msg.title"/>:</td>
                          <td width="85%"><input name="noteTitle" type="text" class="input2" size="40" /></td>
                        </tr>
                        <tr>
                          <td valign="top"><s:text name="note.content"/>:</td>
                          <td><textarea name="noteContext" cols="40" rows="5" class="textarea1"></textarea></td>
                        </tr>
                        <tr>
                          <td><s:text name="note.needre"/>:</td>
                          <td><input type="checkbox" name="needRe" value="1" />
                            <s:text name="note.needre.notice"/></td>
                        </tr>
                        <tr>
                          <td> </td>
                          <td>
                            <input name="Submit2" type="button" class="button1" onclick="noteRe('<s:property value="#note.id"/>');" value="<s:text name="bbscs.re"/>" />
                            <input type="button" name="closeSendInButton" class="button1" onclick="closeNoteSendInNote('<s:property value="#note.id"/>');" value="<s:text name="bbscs.close"/>"/>
                          </td>
                        </tr>

                      </table>
                      </form>
                    </div>
                    <div id="needRe<s:property value="#note.id"/>" style="display:none"><s:property value="#note.needRe"/></div>
                  </div>
                </td>
我们先看loadNoteReadInbox()函数：
function loadNoteReadInbox(noteId,page) {

needRe_span = document.getElementById("needRe"+noteId);//是否需要回复！
var needRe_num_val = needRe_span.innerHTML;
var needRe_int_val = parseInt(needRe_num_val);
if (needRe_int_val == 1) {
    autoRe(noteId);//调用回复！见下
}
displayElement("noteDiv"+noteId);//显示note在noteDiv+noteId处!
var urls = getActionMappingURL("/note");
var pars = "action=readinbox&ajax=shtml&id=" + noteId + "&page=" + page;
var myAjax = new Ajax.Updater("noteDetail"+noteId, urls, {method: 'get', parameters: pars});//更新的是noteDetail处div,注意另外一个noteSend的div还没显示出来！
$('noteIsNew'+noteId).innerHTML = "<img src="images/note_old.gif"/>";
}
-->
function autoRe(noteId) {
var cRe = confirm(confirmNoteRe); //var confirmNoteRe = "<s:text name="js.confirmNoteRe"/>";
if (cRe) {
    var oNoteAutoReOjbAjax = new NoteAutoReOjbAjax(noteId);
    oNoteAutoReOjbAjax.autore();
}
else {
    return false;
}
}
-->
ar NoteAutoReOjbAjax = Class.create();

NoteAutoReOjbAjax.prototype = {
initialize: function(noteId) {
this.noteId = noteId;
},

autore: function() {

    var url = getActionMappingURL("/note");
    var pars = "action=autore&ajax=xml&id=" + this.noteId;
    var myAjax = new Ajax.Request(url, {method: 'get', parameters: pars, onComplete: this.autoreCompleted.bind(this)});
},

autoreCompleted: function(res) {
resText = res.responseText;
var jsonMsgObj = new JsonMsgObj(resText);
var codeid = jsonMsgObj.getCodeid();
alert(jsonMsgObj.getMessage());
if (codeid == "0") {
  refreshBoxNum("outbox",1);//增加发件箱note数
/**
function refreshBoxNum(boxName,num) {
var num_span;
if (boxName == "inbox") {
    num_span = document.getElementById("inboxNumDiv");
}
else {
    num_span = document.getElementById("outboxNumDiv");
}
var num_val = num_span.innerHTML;
var int_val = parseInt(num_val);
var new_int_val = int_val + num;
num_span.innerHTML = new_int_val;
}
*/
  document.getElementById("needRe"+this.noteId).innerHTML = "0";//不需要回复了！
}
}
};
好，我们看noteInbox.jsp的底部相关JSP代码：
<tr>
          <td colspan="3" class="bgColor3">
            <table width="100%" border="0" cellpadding="0" cellspacing="0">
              <tr>
                <td width="67%"><s:text name="bbscs.pagebreak"/>: <bbscs:pages value="%{pageList.pages}" javaScript="loadNoteInboxUrl"/> <a href="javascript:;" onclick="delAllInBox();"><s:text name="note.delall"/></a></td>
                <td width="33%">
                  <div align="right"><s:text name="note.selected"/>:
                    <select name="noteOp" class="select1">
                      <option value="1" selected="selected"><s:text name="bbscs.del"/></option>
                      <option value="2"><s:text name="note.getout"/></option>
                    </select>
                    <input name="Submit" type="submit" class="button1" onclick="noteOpInBox();" value="<s:text name="bbscs.exe"/>"/>
                  </div>
                  <div id="cpage" style="display:none"><s:property value="%{pageList.pa
