Question

  如题:  if (typeof window['DWRUtil'] == 'undefined')
window.DWRUtil = dwr.util;
function views() {
UserDwr.onmouseoves(callBack);
}

function callBack(lst){
 for(var i=0;i<lst.length;i++){
     alert(lst[i].Names);
 }
} 
<input type="submit" value="tijiao" onclick="views();">
<div id="PlanItemId"></div>java Code
public List onmouseoves(){

Query query = this.services.CreateQuery("FROM Test");
List lst = query.list();
List dwrlist = new ArrayList();
Test test = new Test(); 
for(int i=0;i<lst.size();i++){
test = (Test)lst.get(i);
dwrlist.add(test);
}
 
return dwrlist;
}

Answer 2

多年不用dwr了
目前采用 jquery + json 
轻松，简单

Answer 3

jquery返回的json数组，可以满足你的这种需求，DWR一般用来执行服务端的boolean逻辑，不适合用来传送数据

Answer 4

 目前已经在使用ext了 不想那么麻烦了, 能单纯的js就单纯的js吧还是讨论下 怎么把list数据 显示出来啊 , 多谢了

Answer 5

闲着没事 回帖子了 但愿可以帮忙这是我项目的一小部分 copy来给你看
    function dwrUser(pageNo){
        Page.getPlayerPagingList(pageNo,process);   //对应的java里边的方法 返回值为List<Player>
                                                                                    //pageNo为参数   process回调函数
    }
    
     function process(item)
     {
       DWRUtil.removeAllRows("dwrTable");    
       var cell=[
        function(item){return item.id},
        function(item){return item.name},               //注意这段item.name可取出对应属性
        function(item){return item.score}
       ];
       DWRUtil.addRows("dwrTable",item,cell);
     }

Answer 7

    public List onmouseoves(){
        
        Query query = this.services.CreateQuery("FROM Test");
        List lst = query.list();      //为什么不直接把这个List返回了        List dwrlist = new ArrayList();
        Test test = new Test(); 
        for(int i=0;i<lst.size();i++){
            test = (Test)lst.get(i);
            dwrlist.add(test);
        }
         
        return dwrlist;
    }
取的值是null 可能是后台没读到值 7楼写的很清楚
