帮助jQuery自动完成和JSON响应

Question

我有一个ASP.NET 2.0 json网络服务，该服务返回以下响应

<?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>

当我将其绑定到测试框以用于自动完成插件时，在下拉列表中没有看到任何结果。 我用萤火虫检查了是否已拨打电话。

我的前端通话如下所示

$(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
 }); 
  });

有人可以让我知道我做错了吗？

谢谢

那不是JSON :)那是包裹在XML中的JSON字符串。 您需要使您的WebMethod返回JSON而不是XML。

例如，装饰您的WebMethod：

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