帮助使用jQuery自动完成和JSON响应 [英] Help with jquery autocomplete and json response

问题描述

我有一个返回以下响应的一个ASP.NET 2.0的JSON Web服务

I have the a ASP.NET 2.0 json web service that returns the following response

<?xml version="1.0" encoding="utf-8" ?> 
  <string xmlns="http://microsoft.com/webservices/">[{"CUName":"Raytown-Lee\u0027s Summit Comm CU","CUCity":"RAYTOWN","CUState":"MO","CUContractNo":"02406"},{"CUName":"Summit Credit Union","CUCity":"MADISON","CUState":"WI","CUContractNo":"04800"},{"CUName":"Summit Credit Union","CUCity":"GREENSBORO","CUState":"NC","CUContractNo":"03200"},{"CUName":"Summit Hampton Roads FCU","CUCity":"NORFOLK","CUState":"VA","CUContractNo":"04504"},{"CUName":"SummitOne Federal CU","CUCity":"OGDEN","CUState":"UT","CUContractNo":"14301"}]</string>

在我这个绑定为与自动完成插件使用我的测试中，我没有看到在下拉列表中的任何结果。我检查与萤火虫的呼叫。

When I bind this to my test box for use with the autocomplete plugin, I don't see any results in the dropdown. I checked with firebug that the call is made.

我的前端调用看起来像下面

My front end call looks like below

$(document).ready(function() {
 $("#city").autocomplete("CUList.asmx/GetCUList", {
  dataType: 'jsonp',
  parse: function(data) 
  {
   var rows = new Array();
   for(var i=0; i<data.length; i++){
    rows[i] = { data:data[i], value:data[i].CUName, result:data[i].CUName };
   }
   return rows;
  },
  formatItem: function(row, i, n) {
   return row.CUName + ', ' + row.CUCity;
  },
  max: 50
 }); 
  });

可有人请让我知道我做错了？

Can someone please let me know what I am doing wrong?

感谢

推荐答案

这不是JSON :)这是一个JSON字符串包裹在XML。呦需要让你的WebMethod返回JSON，而不是XML的。

That's not JSON :) That's a JSON string wrapped in XML. Yo need to make your WebMethod return JSON instead of XML.

例如装饰你的WebMethod：

For example decorate your WebMethod:

[WebMethod, ScriptMethod]
public List<thing> GetCUList()
