Question

Im using jquery and dojo to search a json string

   $.get('json.txt', function(data) { //alert(data); works fine

      dojo.require("dojox.json.query");
      query = "(product_tonnage = "+$('#slider-tonnage-value').val()+")";
      var json_db = jQuery.parseJSON(data);

      var results = "";
      results = dojox.json.query(query, json_db);
             alert(results.length); //it must contain 4 results
      });

How ever im getting the error “JSON.parse: unexpected non-whitespace character after JSON data”

jQuery’s $.get() method (and other Ajax methods) will parse the JSON for you (assuming the MIME type of the response is right). You can also add a “json” parameter to the end of your $.get() call to explicitly tell jQuery you expect JSON back.

Calling JSON.parse() yourself will then try to parse an (already parsed) object rather than the JSON string.
