AJAX - 在JQUERY中返回的Parse JSON对象

Question

I stucked a little bit in here>

My php script returns this JSON (in variable response) (encoded array with json_encode) :

{"1":{"id":"pvv001","tooltip":"tip1","link":"http:\/\/domain\/file1.html"},"2":{"id":"pvv002","tooltip":"tip2","link":"http:\/\/domain\/file2.html"}}

I hope this is valid JSON object ...

Then here is JavaScript function which should get this string and process it - load to ELEMENT "id" a content of "link".

function jLinks(idchapter)
{
    var url = 'ajax_loadlinks.php';
    var data = {
        idchapter : idchapter
    };
    $.post(url,data, function(response)
    {
        //$('#coursecontent').html(response);

        var obj = JSON.parse(response);
        for (var i=0; i<obj.length; i+1)
        {
            $('#'+obj[i].id).html('<a href="'+obj[i].link+'">link</a>');
        }

    });
}

It is not throwing any error in browser or console, but elements are not updated at all.

I quess my parsing and accessing data is wrong somehow, but I have no idea how to debug.

As your string is an object not array, so you need $.each method to loop over each key of object.

var obj ={
  "1": {
    "id": "pvv001",
    "tooltip": "tip1",
    "link": "http:\/\/domain\/file1.html"
  },
  "2": {
    "id": "pvv002",
    "tooltip": "tip2",
    "link": "http:\/\/domain\/file2.html"
  }
};

$.each(obj,function(i,v){
    $('#'+v.id).html('<a href="'+v.link+'">link</a>');
});
