Store json data returned using javascript

Question

I have json string retuned via a ajax call

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

});

The returned json response from server is

{
   _emptyscopedata: [
      {},
      {}
   ],
   errMsgBuffer: {
      errMsg: ''
   },
   descriptor: [
      {
         template: 'projects/mobile/market/mostactives.xsl',
         componentname: 'getmostactives'
      },
      {
         template: '',
         componentname: 'quotelist'
      }
   ],

I want to show some of the values of the response on the site. But I am not able to retrieve the values. Can someone help.

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

and if you wanted to loop through all descriptors:

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

or:

alert(result['invest.mostactive'].MoverExchange);

etc... depending on what you want to show

You're a machine, that's all I've got to say. ;)

I want to show the values from "quote.quote". But I get error 'TypeError: Result of expression 'result.quote' [undefined] is not an object'. So, I want to know why the result.quote.quote[0].symbol does not work

Darin Dimitrov Over a year ago

@Hozefa, did you try alert(result['quote.quote'][0].symboldesc);?

Hozefa Over a year ago

Yes, I did try that. I got to work using alert(result['quote.quote'][0].symboldesc);

You can use define a global variable in case you want to use the response out the success function scope. Just use

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
    }
});
