但是它没有返回任何值? 我如何获得价值?

but it didn't returns any value? how can i get the value?

推荐答案

<a>标记创建一个锚，该锚没有值(通常只有创建输入的标记才有).如果需要其属性之一的值，则可以使用.attr()函数.

The <a> tag creates an anchor, which doesn't have a value (generally only tags that create inputs do). If you want the value of one of its attributes, then you can use the .attr() function.

例如:

alert($(this).attr('at')); // alerts "privat"

如果要获取其文本值(<a>和</a>标记之间的内容)，则可以使用.text()函数:

If you want the value of its text (the content between the <a> and </a> tags), you can use the .text() function:

alert($(this).text()); // alerts "Privat"

如果您的HTML有点不同，并且您的<a>标签包含其他HTML，而不仅仅是文本，如下所示:

If your HTML was a bit different, and your <a> tag contained other HTML, rather than just text, like this:

<a href="?at=privat" at="privat" class="Privat"><span>Privat</span></a>

然后您可以使用.html()函数执行此操作(它将返回<span>Privat</span>).即使将.text()包裹在一个跨度中，它仍将仅返回"Privat".

Then you could use the .html() function to do that (it would return <span>Privat</span>). The .text() would still just return "Privat" even though it's wrapped in a span.
