使用jQuery，如何获取元素的文本值？

Question

how do I retrieve the text between the href tag?

<a href="blah">GET THIS TEXT</a>

It is wrapped in this DOM:

<div class="c1">
   <div class="c2"><a href="#">GET THIS TEXT</a>
   </div>
</div>

Answer 1

You are looking for the text() property:

$('a', 'div.c2').text();

The reason div.c2 is defined as the second argument is because it would then be the context of the selector. By default jQuery searches the entire document when you use $() , by specifying div.c2 it is only going to search inside of <div> 's with a class of c2.

Keeping this in mind, you could also rewrite the above like this:

$('div.c2 a').text();

Most people prefer this because it is the syntax that you would use to select this element in a CSS stylesheet. However, jQuery then has to figure that out. You could even do:

$('div.c2').find('a').text();

However, I prefer the context method as I feel it is cleaner and marginally faster, not that it matters.

There is also the html() property, which gets the contents, including HTML .

So if your link was like this:

<a href='#'><b>Hi There</b></a>

Then:

$('a').text(); // would return Hi There
$('a').html(); // would return <b>Hi There</b>

Answer 2

I think that .text() or .html() will work, depending on whether you don't or do want any markup that appears inside the tag.

var txt = $('div.c2 > a').text();

var html = $('div.c2 > a').html()
