jQuery:查找包含嵌套ul的列表项的文本 [英] jQuery: Find the text of a list item that contains a nested ul

问题描述

我有以下内容:

<ul id="list">
<li>item1
    <ul>
        <li>sub1</li>
        <li>sub2</li>
    </ul>    
</li>
</ul>

我想回复li点击事件，并在其他地方使用li的文本.但是，如果单击的是包含嵌套ul的li，那么我当然会得到所有元素的文本.

I'd like to respond to a li click event and use the text of the li elsewhere. However, if the click is on an li that contains a nested ul, I of course get the text of all elements.

$("#list li").click(function() {
    alert($(this).text());
});

按预期返回item1sub1sub2.

returns item1sub1sub2, as expected.

如果单击项目1 li，我不知道如何获取"item1".我没有运气就尝试了以下方法:

I can't figure out how to get just 'item1' if the item 1 li is clicked. I tried the following (among other things) with no luck:

$("#list li").click(function() {
    alert($(this).filter("ul").text());
});

有什么想法吗?

编辑

这是一个示例的片段-可能有多个层次.我也不想将列表项文本包装在跨度或其他标记中.

This is a snippet of an example - it could be multiple levels deep. I also do not want to wrap the list item text in a span or other markup.

推荐答案

这种方法呢?克隆对象，删除克隆的子对象，然后然后查找文本内容.

What about this approach? Clone the object, remove the clone's children and then find the text content.

$("#list li").click(function () {
    alert($(this).clone().children().remove().end().text());
}

也许不是最有效的方法，但它是完全直观，整洁的，而且您不必弄乱html.

Perhaps not the most efficient approach, but it's entirely intuitive, pretty tidy, and you don't have to muck with your html.
