dwr刷新表格

   配置dwr.xml文件

xml 代码

<!DOCTYPE dwr PUBLIC
    "-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN"
    "http://www.getahead.ltd.uk/dwr/dwr10.dtd">
<dwr>
    <allow>
        <create creator="spring" javascript="UnitManager"><!-- 由spring管理，直接访问serverce,构建一个UnitManager.js -->
            <param name="beanName" value="unitManager" />
            <include method="getAllList" /><!-- 可用方法-->
        </create>

       <convert converter="bean"
            match="com.bigner.unitModule.model.Unit">  <!-- 指定bean -->
            <param name="include" value="id,unitName,baseVal"></param><!--  取出指定参数 -->
        </convert>

    </allow>
</dwr>

   在jsp中创建一个table

<table>
<thead>
<tr>
<td>&nbsp;</td>
<td><fmt:message key="product.type"/><!-- 获取资源文件 -->
</td>
</tr>
</thead>

<tbody id="refreshBody"><!-- 在这刷新 -->
</tbody>
</table>

    那么js事件代码

js 代码

<script type='text/javascript' src='/BoyiShoeErp/dwr/interface/UnitManager.js'></script>
    <script type='text/javascript' src='/BoyiShoeErp/dwr/engine.js'></script>
    <script type='text/javascript' src='/BoyiShoeErp/dwr/util.js'></script>
function selOtherUnit(){
       var sel = document.getElementById("unitInfo");
       UnitManager.getUnitList(setRefreshTable,sel.options[sel.selectedIndex].value); //根据unitInfo改变值，从数据库取得数据，返回值由setRefreshTable进行处理
    }
function setRefreshTable(data){//data接受返回数据,这返回的是一个Unit对象
      if(data!="" && data!=null){
          DWRUtil.removeAllRows("refreshBody");//删除table的更新元素
          DWRUtil.addRows("refreshBody", data, [ getCheck,getUnitName ],//getCheck,getAllUnit是表的对应的列,
          {
             rowCreator:function(options) {//创建行，对其进行增添颜色
             var row = document.createElement("tr");
             var index = options.rowIndex * 50;
             row.style.color = "rgb(" + index + ",0,0)";
             return row;
             },
             cellCreator:function(options) {//创建单元格，对其进行增添颜色
             var td = document.createElement("td");
             var index = 255 - (options.rowIndex * 50);
             td.style.backgroundColor = "rgb(" + index + ",255,255)";
             td.style.fontWeight = "bold";
             return td;
             }
          });
      }else{
          DWRUtil.removeAllRows("refreshBody");
      }
}
var getCheck = function(unit) {
          return '<input type="radio" name="unitCheck" value='+unit.id+' onclick="readUnitId(this.value);" />';
};
var getUnitName = function(unit) { return unit.name };

      到这就可以刷新动态刷新table
      与之相对应的刷新select方法是

js 代码

DWRUtil.removeAllOptions("refreshSelect");
DWRUtil.addOptions("refreshSelect", [" "]);
DWRUtil.addOptions("refreshSelect", unit,"id","name");

       就不多记录，参考 getahead.ltd.uk/dwr/documentation。

楼主选择代码的类型不对。最好都选择XML类型，否则有些代码显示不正常
