DWR Struts Servlet Bean JavaScript

http://liaijun82-live-cn.iteye.com/blog/342396

  <servlet>
    <servlet-name>action</servlet-name>
    <servlet-class>org.apache.struts
.action.ActionServlet</servlet-class>
    <init-param>
      <param-name>config</param-name>
      <param-value>/WEB-INF/struts
-config.xml</param-value>
    </init-param>
    <init-param>
      <param-name>debug</param-name>
      <param-value>2</param-value>
    </init-param>
    <load-on-startup>2</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>action</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>
  <servlet>
    <servlet-name>dwr
-invoker</servlet-name>
    <servlet-class>uk.ltd.getahead.dwr
.DWRServlet</servlet-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>true</param-value>
    </init-param>
    <load-on-startup>10</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>dwr
-invoker</servlet-name>
    <url-pattern>/dwr
/*</url-pattern>
  </servlet-mapping>

dwr .xml中加入struts 的設定,其中formBean的參數的value值,會對應到struts -config.xml中<form-beans>的設定

  <dwr
>
  <allow>
    <create creator="struts
"
 javascript="testFrm"
>
      <param name="formBean"
 value="testActionForm"
/>
    </create>
  </allow>
  </dwr
>

struts -config.xml

  <struts
-config>
  <form-beans>
    <form-bean name="testActionForm"
 type="test.struts
.testActionForm"
 />
  </form-beans>
  <action-mappings>
    <action name="testActionForm"
 path="/testAction"
 scope="session"
 type="test.struts
.testAction"
 validate="false"
>
      <forward name="display"
 path="/display.jsp"
 />
    </action>
  </action-mappings>
  <message-resources parameter="ApplicationResources"
 />
</struts
-config>

testActionForm.java,getDate()會透過dwr ,取得現在最新的日期

package

 test.struts
;
 
import

 org.apache.struts
.action.*;
import

 java.util.*;
 
public

 class

 testActionForm extends

 ActionForm {

 
    private

 String strDate;
 
    public

 void

 setStrDate(String strDate) {

        this.strDate = strDate;
    }

 
    public

 String getStrDate() {

        return

 strDate;
    }

 
    //dwr


    public

 String getDate() {

        Date date = new

 Date();
        return

 date.toString();
    }

 
}

testAction.java

package

 test.struts
;
 
import

 org.apache.struts
.action.ActionMapping;
import

 org.apache.struts
.action.ActionForm;
import

 javax.servlet.http.HttpServletRequest;
import

 javax.servlet.http.HttpServletResponse;
import

 org.apache.struts
.action.ActionForward;
import

 org.apache.struts
.action.Action;
import

 org.apache.struts
.action.*;
 
public

 class

 testAction extends

 Action {

    public

 ActionForward execute(ActionMapping mapping, ActionForm form,
                                 HttpServletRequest request,
                                 HttpServletResponse response) {

 
        testActionForm actionForm = (testActionForm) form;
        System.out.println(actionForm.getStrDate());
        return

 mapping.findForward("display"
);
    }

}

date.jsp,在form的部分,請用struts 的 tag library,我把<html:text property="strDate" size="30" >改成<input type="text" name="strDate">後,無法正常的接受到值.

<%@ page contentType="text/html; charset=Big5"
 %>
<%@ taglib uri="/WEB-INF/struts
-bean.tld"
 prefix="bean"
 %>
<%@ taglib uri="/WEB-INF/struts
-html.tld"
 prefix="html"
 %>
<%@ taglib uri="/WEB-INF/struts
-logic.tld"
 prefix="logic"
 %>
<html>
<head>
<title>title</title>
  <script type='text/javascript'
 src='dwr
/interface/testFrm.js'
></script>
  <script type='text/javascript'
 src='dwr
/engine.js'
></script>
  <script type='text/javascript'
 src='dwr
/util.js'
></script>
</head>
<SCRIPT LANGUAGE="JavaScript"
 type=""
>
 
function refreshDate() {

    testFrm.getDate(populateDate);
}

 
function populateDate(data){

   DWRUtil.setValue('strDate'
, data);
}

 
</script>
 
<body>
 
<html:form action="testAction.do"
>
date：
<html:text property="strDate"
 size="30"
 >
</html:text>
 
<input type="button"
 onclick="refreshDate();"
 value="更新日期"
/>
<br/>
 
  <html:submit>送出
  </html:submit>
</html:form>
</body>
</html>

display.jsp

<%@ page contentType="text/html; charset=Big5"
 %>
<%@ taglib uri="/WEB-INF/struts
-bean.tld"
 prefix="bean"
 %>
<%@page import="test.struts
.*"
%>
<html>
<head>
<title>
test
</title>
</head>
<body bgcolor="#ffffff"
>
<h1>您送出的日期:<br>
<bean:write name="testActionForm"
 property="strDate"
/>
</h1>
</body>
</html>
