Question

我已经完成了http://jsfiddle.net/cC8fT/558/，看不出有什么问题

我从维基百科中抓取了<ul><li></li></ul>。我想我至少会尝试使用

列出所有<li>代码的内容

$('ul li').each(function(i) {
    return $(this).text();
});

下面的数据集（它实际上是这个数据集http://en.wikipedia.org/wiki/Reading_and_Leeds_Festivals_line-ups，但我正在尝试一个较小的数据集）

<table class="wikitable plainrowheaders" style="text-align:center;" border="1">
<tr>
<td>Reading Friday</td>
<td>Reading Saturday</td>
<td>Reading Sunday</td>
</tr>
<tr>
<td>Leeds Saturday</td>
<td>Leeds Sunday</td>
<td>Leeds Friday</td>

然而，我得到的只是数据集，而不是内容。第二阶段是剥离任何URL，只需抓取文本

Answer 1

使用map代替each：

var texts = $('ul li').map(function() {
    return $(this).text();
}).get();

获取所有列表内容并删除链接
