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();
    }
  });
}

我正在尝试解析这个数组

    "nodes": [
        {
            "node-title" : "Slide for Album Post",

}

问题是我在 jQuery.js 文件本身上遇到错误。

G is undefined

Line 12

有人知道发生了什么吗？如果我在 .each() 语句之前发出警报，它会发出警报，但如果我在 .each() 语句中发出警报，我什么也得不到，并且变量永远不会被构建。

谢谢！

$.ajax({
 url: jsonLink,
 dataType: 'json',
 success: function(data) {
  $.each(data.items, function(i,item){
  // your code ..
  });
 }
});

您正在通过使用$.ajax(). 相反，它更容易使用$.getJSON()。

对于 PHP 数组 json 编码

<?php $arr= array('1'=>'2', 2=>'3',4000=>'400','x'=>'alfa'); ?>

<input type="hidden" value="<?php echo json_econde($arr); ?>" id="phpjsonencoded">

您可以使用

var x = "[" + $('#phpjsonencoded').val() + "]";

var obj = $.parseJSON(x);

$.each(obj[0],function(key,val){

console.log(val);

});

只需使用row.node-type, row.videoetc 而不是 using row['node-type'], row["video"]etc 。

希望这会有所帮助。
