接收数据json / jquery

Question

Good evening!

Trying to learn how to receive data with json/JQuery using following function. I've managed to store the php variable in a json variable (var ar), and it seems to contain what I want (according to console.log, document.write says [object Object]) but I'm not sure how to implement it in the function.

Depending on the reason for your implementation, but if you are just processing data from a post, it would probably be more efficient to parse the JSON via PHP not with jQuery.

I have made a simple example about retrieving JSON data and parsing the result data, 1 key at a time. Depending on your JSON schema you may have to parse each key differently as they may have different children nodes.

var url = "http://beta.json-generator.com/api/json/get/EkRU_ItZl";

$.getJSON( url, function( data ) {
    console.log(data);
    $.each( data, function( key, val ) {
        $('#result').append("Key:" + key + " Value:" + JSON.stringify(val) + "<br/>" );
    });
});

Here is a basic example in jsFiddle: http://jsfiddle.net/DJRavine/k8cxn4u9/

I hope this helps out.
