我有这个jQuery函数
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();
}
});
}
和我试图分析出此阵

问题是我在的jquery.js收到错误文件本身。
G is undefined
http://journeyon.local/sites/all/themes/zen/journeyon/js/jquery-1.3.2.min.js?4
Line 12
任何人有任何线索，这是怎么回事？ 如果我把它提醒就好了。每个（）语句之前发出警报，但如果我的。每个（）语句中提醒我什么也没得到，并且变量永远不会建造。
谢谢！
解决方案
您正在做它用$.ajax()艰辛的道路。它更容易使用，而不是$.getJSON()
其他提示
$.ajax({
url: jsonLink,
dataType: 'json',
success: function(data) {
$.each(data.items, function(i,item){
// your code ..
});
}
});
有关编码的PHP数组JSON
<?php $arr= array('1'=>'2', 2=>'3',4000=>'400','x'=>'alfa'); ?>
<input type="hidden" value="<?php echo json_econde($arr); ?>" id="phpjsonencoded">
可以使用
var x = "[" + $('#phpjsonencoded').val() + "]";
var obj = $.parseJSON(x);
$.each(obj[0],function(key,val){
console.log(val);
});
只要使用row.node-type，row.video等代替使用row['node-type']，row["video"]等
希望这会有所帮助。
