How to parse php response as json in jQuery

Question

In php:

header('content-type: application/json; charset=utf-8');
$res = array("success" => true, "status" =>array(),"path" =>array());
echo(json_encode($res));

I want to access path from above array.

In jQuery I am trying

on("success", function (Text) {
                console.log("l path " + Text[0].path);
            $.each(Text[0].path, function(i,k){
                       console.log(i+"  "+k);
});

It is throwing an error:

Uncaught TypeError: Cannot read property 'path' of undefined'

Use var obj = JSON.parse(Text); and use obj in each. OR use dataType: 'json', in $.ajax configuration options. — Tushar

As mentioned by others, if you want to use the JSON you need to parse it first, otherwise it'll be a string. — Script47

echo(json_encode($res)); are you sure you are getting a valid json out of it? — Jai

Use JSON.parse(), like following:

on("success", function (Text) {
    var response = JSON.parse(Text);
    console.log("l path " + response.path);
    $.each(response.path, function(i,k){
        console.log(i+"  "+k);
    });
}

Not that I down-voted it, but I can guess it happened because it was answered in the comment of the question.

I have also commented @Script47 but i can't put complete code in comment. So answer is best way to expose. I don't know why people downvote without reason. Anyway let OP try this solution.

@Manwal {"success":true,"status":[],"path":[]} this is the output of php. so response[0].path should be response.path

LOL, last time I checked this question, there was one down vote to question and +1 to answer, and this time, -1 to answer and +1 to question. I'm drunk, I suppose :P

I'd use

on("success", function (Text) {
var response = JSON.parse(Text);
console.log("l path " + response[0].path);
$.each(response[0].path, function(i,k){
    console.log(i+"  "+k);
});
}
