Parsing jQuery JSON array with .each function
Written by: J Dawg
Trying to parse this JSON array, if I alert before the .each() statement it alerts just fine, but if I alert inside the .each() statement I get nothing and the variables never get built. Problem is I am getting an error on the jQuery.js file itself. The error is saying G is undefined. I am using jquery version 1.3.2.
I have this jQuery function
function getData(jsonLink){
$(".scrollable .items").html("<img class='loadGif' src='/sites/all/themes/zen/journeyon/images/ajax-loader.gif' alt='' />");
$.ajaxSetup({
url: jsonLink,
global: false,
type: "GET"
});
$.ajax({
url: jsonLink,
success: function(data) {
var output = "";
$.each(data['nodes'], function(i,row){
var linkType = row['node-type'];
var lowerLinkType = linkType.toLowerCase();
var videoLink = row["video"];
var thumbLink = row["thumbnail"];
var posterLink = row["poster-image"];
var nodeTitle = row["node-title"];
var url = row['url-link'];
if(linkType == "Episode"){
output+='<li><a class="myRemote '+lowerLinkType+'" href="'+posterLink+'" ref="'+videoLink+'" title="Play '+nodeTitle+'"><img src="'+thumbLink+'" width="123" height="67" alt="Play '+nodeTitle+'" /></a></li>';
}else if(linkType == "Slide"){
output+='<li><a class="myRemote '+lowerLinkType+'" href="'+posterLink+'" ref="'+url+'" title="Go To '+nodeTitle+'"><img src="'+thumbLink+'" width="123" height="67" alt="Go To '+nodeTitle+'" /></a></li>';
}
});
$(".scrollable .items").html("").append(output);
remoteControl();
}
});
}
And I am trying to parse out this Array

Anyone have any clue what’s going on?
if I alert before the .each() statement it alerts just fine, but if I alert inside the .each() statement I get nothing and the variables never get built.
Thanks!
You’re doing it the hard way by using $.ajax(). It’s easier to use $.getJSON() instead.
$.ajax({
url: jsonLink,
dataType: 'json',
success: function(data) {
$.each(data.items, function(i,item){
// your code ..
});
}
});
Just use row.node-type, row.video etc instead of using row[‘node-type’], row[“video”] etc.
Hope this will help.
