Question

我已经使用了一段时间了，我似乎无法弄明白我发布了一个问题，它有几个很好的答案我正在使用第二个答案的代码（你应该阅读我的第一篇文章，以了解我来自哪里）parsing nested JSON String objects with JQuery/PHP?

所以基于代码User：Useless Code

它的工作完美，但问题是数据包含在同一页面文件中，并且只有一次专辑...我需要从中拉出json

http://www.ggcc.tv/json2php/posts.php

并让主索引页面ggcc.tv/json2php/index.html列出post.php中的所有相册和内容

请帮助并使用完整代码（因为我是json / php / jquery等新手......

根据用户建议使用代码：无用代码

基本上我需要代码（用户建议：无用代码）从http://www.ggcc.tv/json2php/posts.php中提取数据/每张专辑并列出每张专辑及其曲目

请阅读此帖子我的原帖并在此留下您的答案，谢谢

Answer 1

试试这个：

<script type="text/javascript">
  $(document).ready(function() {
    var url="/json2php/posts.php";
    $.getJSON(url,function(data){
      $.each(data.posts,function(i,post) {
        var content,
        trackInfo = '',
        tracks = post.tracks;

        // loop over the tracks and collect info
        $.each(tracks, function (i) {
          trackInfo += '<a href="' + tracks[i].url + '">' + tracks[i].name + '</a> ';
        });

        content = '<div class="post">'+
        '<h1>'+post.album+'</h1>'+
        '<p><img src="'+post.artwork+'"width="250"></img></p>'+
        '<p><strong>'+post.church+'</strong></p>'+
        '<p>Description: <strong>'+post.des+'</strong></p>'+
        '<p>Base url:  <em>'+post.baseurl+'</em></p>'+
        '<p>Tracks:  <li>'+ trackInfo +'</li></p>';
        '<hr>'+
        '</div>'

        $("#content").append(content);
      });
    });
  });
</script>

此外，您在与此列表页面相同的域上连接的posts.php是什么？我认为它是，但如果不是那么你应该知道浏览器将阻止跨域通信，但服务器不会这样你可以通过在webroot / json2php / posts.php创建一个文件来解决这个问题：

<?php
  echo file_get_contents('http://www.ggcc.tv/json2php/posts.php');
?>

Answer 2

远离尝试自己解析json ..使用专门将json转换为html的jquery模板引擎，如json2html。

下面是一个完整的代码示例（确定您要显示的一些相册详细信息，应该很容易添加剩下的内容），这会占用您的一个相册并呈现曲目列表。

请注意，嵌套轨道使用对json2html

的子调用进行渲染

{tag:'div',children:function(obj){return($.json2html(obj.tracks,track_transform));}}

使用变换'track_transform'将轨道渲染成链接。

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="http://json2html.com/js/jquery.json2html-2.3-min.js"></script>

<div id='list'></div>

<script>

//Transform used to create a link for the track

        {tag:'p',children:[
            {tag:'span',html:'Tracks: '},
            {tag:'div',children:function(obj){return($.json2html(obj.tracks,track_transform));}}
        ]}
    ]};

//Render the json into a list of albums 
$('#list').json2html(json, album_transform);
</script>

使用jquery将嵌套的json对象转换为html
