Read JSON with out AJAX (jQuery)

I have a JSON object with data and i am trying to take that object and read it without using getJSON. The JSON is already loaded on the page. It is not on the callback of an AJAX call using jQuery.

I have worked with AJAX and jQuery to display JSON after making a call, but not sure how to read it if it is already on the page.

Any ideas? Thanks.

So going from the example from the link above you have:

var myObject = eval('(' + myJSONtext + ')');

where myObject will be a javascript object containing the result of myJSONtext

So you would use it with:

$(#input).val(myObject.DataName);

Basically after calling eval myObject will be what you would have expected if you would have called getJSON.

Use the eval function

Could you elaborate a little bit?

My goal is to read the JSON and update the input with the value of the json

$(#input).val(object.DataName);

Something along those lines for each of my inputs.

Starting to make a bit more sense, never used that function before, I checked out the simple example here: http://www.w3schools.com/jsref/jsref_eval.asp

Do you have:
a. an ACTUAL object or
b.a json string that you need to convert to json?

If a, then you can use a for-in construct to iterate over the object properties.
If b, then you can use $.parseJSON to convert the json string to an object.
