ajax+jquery实现父页面弹出子页面，选择提交后给父页面传值

父页面

<script type="text/javascript">

　　//obj是父页面点击的控件
    function openRecord(obj){
        var url = "provider!select.do";//执行后台url
        var prop = 'dialogWidth:980px;dialogHeight:500px;dialogLeft:200px;' +  
           'dialogTop:150px;resizable:no;center:yes;status:yes'; 
           
        //改变id，供子页面获取
        obj.id = "proNumSelect";
　　　　//先改变tr的值，让子页面定位到该tr
        obj.parentNode.parentNode.id="trSelect";
        $("#trSelect input[id='providerFullnames']").attr('id','proFullnameSelect');
        $("#trSelect input[id='proId']").attr('id','proIdSelect');
        
        var openWindows = window.open(url,window, prop);
    } 
</script>

子页面

<script type="text/javascript">
    function fnParent(){   
        //window.opener.location.reload();//刷新父窗口   
        window.close();   
    }  
    function onSelected(){
        var proIds = document.getElementsByName("providerId");
        var proId = "";
        for(var i=0;i<proIds.length;i++){
            if(proIds[i].checked)
            proId = proIds[i].value;
        }
        if(proId.length != 0){  
            $.ajax({   
                type:'post',   
                url:'provider!setChileValue.do',//调用的方法
                data:'proId='+proId,
                success:function(data){
                      var proMap = eval(data); //转换数组
                    
                    //给父窗口传值
                    window.opener.document.getElementById("proIdSelect").value=proMap[0].proId;
                    window.opener.document.getElementById("proNumSelect").value=proMap[0].proNumber;
                    window.opener.document.getElementById("proFullnameSelect").value=proMap[0].proFullname;
                    
                    //将父窗口id恢复原来的
                    window.opener.document.getElementById("trSelect").id="";
                    window.opener.document.getElementById("proIdSelect").id="proId";
                    window.opener.document.getElementById("proNumSelect").id="providerNumbers";
                    window.opener.document.getElementById("proFullnameSelect").id="providerFullnames";
                    fnParent();
                    }
                })
        }else{ 
               alert("请先选一行数据!"); 
        }
    }
      
</script>

后台

    //其他页面选择供应商资料的时候调用
    public String select(){
        List<Provider> cusList = providerService.findByPager();
        pager.setList(cusList);
        return SELECT;
    }
    
    //子页面选择供应商资料后执行的方法
    public void setChileValue(){
        String proId = (String)this.getRequest().getParameter("proId");
        Provider selectProvider = providerService.get(proId);
        Map map = new HashMap();
        map.put("proId", proId);
        map.put("proNumber", selectProvider.getNumber());
        map.put("proFullname", selectProvider.getFullname());
        try {
            HttpServletResponse response = this.getResponse();
            response.setContentType("text/plain;charset=UTF-8");
            JSONArray array = JSONArray.fromObject(map);
            response.getWriter().print(array);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
