I have following code for reading a JSON file.It is giving no error but i am getting null in the variable:

var myData = null;
$.ajax({
    type: 'GET',
    async: false,
    url: 'myJson.json',
    dataType: 'json',
    success: function (r) {
        myData = r;
    }
});

Below is my JSON file:

{items:[{value:"1",name:"John"},{value:"2",name:"Henry"}]};

• javascript
• jquery
• json

• 3 Why not use $.getJSON instead? – Marty Commented May 23, 2013 at 5:05
• i tried without semicolon also – Aquarius24 Commented May 23, 2013 at 5:12
• check here for valid or not – M.I.T. Commented May 23, 2013 at 5:12
• 1 async : true.. ajax call should be asynchronous always. and your json is wrong as mentioned by benjamin in below post. Try jsonLint to test whether your json is in correct format or not, always. – Mr_Green Commented May 23, 2013 at 5:27

Your JSON is invalid.

An object serialized in JSON is in the following format:

Where string is:

JSON strings must be escaped. You're missing the "s.

A correct JSON would be:

{"items":[{"value":"1","name":"John"},{"value":"2","name":"Henry"}]}

How I created it

Even if I hadn't remembered or looked up the specific JSON rules, you can always produce the JSON from the JS variable assuming it's serializable (in your case it is) by:

• Open a JavaScript console
• Type var a = and paste your object literal
• Press enter.
• Type JSON.stringify(a);
• Press enter. Copy the result.
• Paste the result in your external .json file. JavaScript's JSON.stringify produces valid JSON.
