Question

I am using jquery to receive a few lines of javascript and get this err

Unexpected token ILLEGA

This is the complete json I am trying to parse. JSON Lint does not complain…

    "executionResult": "",
     "outputText": "",
     "stacktraceText": "groovy.lang.MissingPropertyException: No such property: asfdsf for class: Script1\n at Script1.run(Script1.groovy:1)\n  at

Answer 1

Your JSON is fine, so apparently what you’re asking jQuery to parse isn’t quite what you’ve quoted, as jQuery is happy to parse it. In that example I’m loading the JSON text via ajax.

If you’re reading the JSON text from a JavaScript string rather than by loading it from somewhere, e.g.:

var str = '{ ' +
          '"executionResult": "",' +
          '"outputText": "",' +
          '"stacktraceText": "..."' +
          '}';

…then quote the actual string literal you’re trying to parse, and we can tell you what’s wrong with it. But that JSON is fine.
