存储使用javascript返回的json数据

我通过ajax调用重新调整了json字符串

$.ajax({
            type: 'GET',
            url: quoteURL,
            dataType: 'json',
            timeout: 10000,
            crossDomain: true,
                 success: function(result) {
                /// required code       
               }

});

服务器返回的json响应为

{
   _emptyscopedata: [
      {},
      {}
   ],
   errMsgBuffer: {
      errMsg: ''
   },
   descriptor: [
      {
         template: 'projects/mobile/market/mostactives.xsl',
         componentname: 'getmostactives'
      },
      {
         template: '',
         componentname: 'quotelist'
      }
   ],
   'invest.mostactive': {
      MoverExchange: 'NSDQ',
      MoverType: 'ACT',
      urlType: ''
   },

我想在站点上显示一些响应值。但我无法检索这些值。 有人能帮忙吗

$.ajax({ 
    type: 'GET', 
    url: quoteURL, 
    dataType: 'json', 
    timeout: 10000, 
    crossDomain: true, 
    success: function(result) {
        alert(result.descriptor[0].template);
    }
});

如果您想循环使用所有描述符：

$.each(result.descriptor, function() {
    var template = this.template;
    var componentname = this.componentname;
    // TODO: process the template and componentname
});

或：

---

等等。。。根据您想要显示的内容，您可以使用定义全局变量，以防将响应用于成功函数范围之外。 只用

var cachedResp;//at global scope
$.ajax({ 
    type: 'GET', 
    url: quoteURL, 
    dataType: 'json', 
    timeout: 10000, 
    crossDomain: true, 
    success: function(result) {
        cachedResp = result; //this is now available out of the function
    }
});

你是一台机器，这就是我要说的全部我想显示“quote.quote”中的值。但是我得到了错误“TypeError:Result of expression”Result.quote“[undefined]不是对象”。所以，我想知道为什么结果是这样的。quote.quote[0]。symbol没有work@Hozefa，您是否尝试了

警报（结果['quote.quote'][0].symboldesc）？是的，我试过了。我开始使用警报（结果['quote.quote'][0].symboldesc）；
var cachedResp;//at global scope
$.ajax({ 
    type: 'GET', 
    url: quoteURL, 
    dataType: 'json', 
    timeout: 10000, 
    crossDomain: true, 
    success: function(result) {
        cachedResp = result; //this is now available out of the function
    }
});
