jQuery 调用WebService 返回的json数据报错

function SetContent(id,value){
               $('#divTitle').html(value);              
              $('#divContent').html("<img src='/help/style/loading2.gif' />");
                  $.ajax({
                    type: 'POST',
                    contentType: "application/json;utf-8", //WebService 会返回Json类型                        
                    url: '/common/Services/WSHelp.asmx/GetContent',                      
                     data:"{id:\""+id+"\"}",
                    dataType: 'json',
                    success: function(data) {

                       $('#divContent').html(data);
                    }
                });  
            }

上面怎么也返回不了正确的数据

改为var o = eval('(' + data + ')');  
$('#divContent').html(data);
提示我缺少'[',去下载查看Request Headers去，找了好久没有找到，不小心到没剑圣域

看了一堆无效，只是有一个地方让我的心顿了一下，因为我调试返回的json数据的格式是这样的

data

{...}

d:中华人民共和国，中华人民共和国，中华人民共和国；

 

里面也有一个d,呵呵，改为data.d试试，没有想到就成功了。

 

下面是成功的例子：

function SetContent(id,value){
               $('#divTitle').html(value);              
              $('#divContent').html("<img src='/help/style/loading2.gif' />");
                  $.ajax({
                    type: 'POST',
                    contentType: "application/json;utf-8", //WebService 会返回Json类型                        
                    url: '/common/Services/WSHelp.asmx/GetContent',                      
                     data:"{id:\""+id+"\"}",
                    dataType: 'json',
                    success: function(data) {

                       $('#divContent').html(data.d);
                    }
                });  
            }

 

其它几招，也许没有用，关键时候你还是可以试试

var json = eval('(' + msg + ')');
