My controller has a method that is returning string representation of a jsonArray as


Now following is the ajax method

function loadPropertyFile(url) {
    type: "GET",
    url: url, 
    dataType: "text",
    success: function(response){
        var obj = jQuery.parseJSON(response);


Here the variable obj after parsing comes out to be

"[{"portal.home":"Home"},{"displaytag.tracking.id":"Item ID"},{"displaytag.tracking.itemName":"Item Name"},{"displaytag.tracking.itemType":"Type"}]"

Now I want to access the values from the keys in js

ie. I want to access the value of key “displaytag.tracking.id”

Problem is when I am doing console.log(obj[0][“portal.home”]); It is giving me error TypeError: obj[0] is undefined

What shall I do ?
