在jsp中创建一个table

<table>
<thead>
<tr>
<td> </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>

 

js 代码

<script type='text/javascript' src='/dwr/interface/UnitManager.js'></script>
<script type='text/javascript' src='/dwr/engine.js'></script>
<script type='text/javascript' src='/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+' οnclick="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

DWRUtil.removeAllOptions("refreshSelect");  

DWRUtil.addOptions("refreshSelect", [" "]);  

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