如何将列表数据动态插入到html表中

我正在使用引导程序。这是我要在其中显示所有列表项的表。

<table id="playlist_table" class="table table-bordered">
    <caption class="text-center">PLAYLIST</caption>
    <thead>
        <tr>
            <th>Song Name</th>
            <th>Singer</th>
            <th>Film</th>
        </tr>
    </thead>
    <tbody id="palylist_table_data">
    </tbody>
</table>

这是我的播放列表：

<ul id="playlist" class="hidden">
    <li Src="Ek%20duje%20ke%20vaaste%20serial%20title%20song.mp3" Title="Ek Duje Ke Vasste" Singer="Unkown" Cover="Album images/ek.jpg"> Ek Duje Ke VAste
    </li>
    <li Src="Lak.mp3" Title="Lakshya ko HAr haal mein Paana HAi" Singer="Shankar Mahadevan" Cover="Album images/lakshya.jpg"> LAkshya
    </li>
</ul>

这是我编写的Jquery代码，但是我无法在表中获取任何数据。

$('.playlist li').each(function(){
        var song = $(this).attr('Src');
        var title = $(this).attr('Title');
        var singer = $(this).attr('Singer');
        var cover = $(this).attr('Cover');

        $('#playlist_table_data').html('<tr>' + '<td>' + '*' + '</td>' + '<td>' + song + '</td>' + '<td>' + singer + '</td>' + '<td>' + title + '</td>' + '</tr>');        
    });

random_user_name

您有几个选择器问题，以及使用了不正确的jQuery函数html而不是append。

这是一个工作的jsFiddle

请注意下面的修订版jQuery：

// Use a document ready, to be sure it waits until all html is loaded
jQuery(function($) {
  // Your ul is ID playlist (#playlist), not CLASS playlist (.playlist)
  $('#playlist li').each(function() {
    var song = $(this).attr('Src');
    var title = $(this).attr('Title');
    var singer = $(this).attr('Singer');
    var cover = $(this).attr('Cover');

    // Your table is #playlist_table, not #playlist_table_data
    // using .html() will replace table contents.  You want .append(), to add them to the end of the table
    $('#playlist_table').append('<tr>' + '<td>' + '*' + '</td>' + '<td>' + song + '</td>' + '<td>' + singer + '</td>' + '<td>' + title + '</td>' + '</tr>');

  });
});
