parsing nested JSON String objects with JQuery/PHP?_问答_开发者

This is the page I'm working on.... http://fremontchurch.net/json_test/

This is the json http://fremontchurch.net/json_test/posts.php

I'm trying to to have a list of tracks names listed and linked through simple html link <a href="URL_GOES_HERE">TRACK NAME GOES HERE</a> to its url

i got everything else in order its just the nested part keeps coming up "[object Object],[object Object],[object Object]"... and so on... each nest has two items a track name and url... what would be the correct way to do this?

heres one object from my json...

    </script>
</body>
</html>

please reply will full code because I'm kinda new to this kind of coding and sometimes i done know where to put it... any help will be very much appreciated, thank you...

You need to loop over each item in post.tracks and collect that information into a string before including it, something like this:

    $.each(json.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);
    });

Working example here: http://jsfiddle.net/3SFE4/

In the same way you're using each to iterate over the posts, you can use each to iterate over the tracks. I've included full code below.

<html>
<body>
    <div id="content">

    </div>
    <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script>

     <script type="text/javascript">
        $(document).ready(function(){
          var url="posts.php";

          $.getJSON(url,function(json){
            $.each(json.posts,function(i,post){

              // Here we generate a fragment for the tracks.
              var tracks = ''; 
              $.each(post.tracks, function(j, track) {
                tracks += '<a href="' + track.url + '">' + track.name + '</a>';
              })

              $("#content").append(
                '<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>'+
                'tracks' + 




                '<hr>'+
                '</div>'
              );
            });
          });
        });
      </script>
