How to find a link in a page based on its href attribute?

I am trying to find the first link of my page which url fit to "AAA" (example).

I first try to get the links with this href:

$('a[href$="AAA"]')

Then selec the first one:

$('a[href$="AAA"]')[0]

Then target the title attribute of this 开发者_高级运维link

$('a[href$="AAA"]')[0].attr("title");

But all of this return me "undefined", at each step. How to do that?

Example anchor:

<a href="contents/medias/images/news/news_test_big.jpg" title="Nouvelle réalisation en ligne 1 FR" target="_blank" class="imageLink">

How about:

$("a[href='AAA']").first().attr("title")
// or
$("a[href='AAA']:first").attr("title")

Then it depends if you want the href to be equal to 'AAA', contains it, starts/ends with it. In that case you wouldn't use href= but href$= for instance. Neil's answer contains the different types of tests you can use.

If you could post your HTML code it would help as well.

$('a[href$="AAA"]') should work fine, but it searches for hrefs that end with AAA.

Try: $('a[href="AAA"]') - Equals AAA
Or: $('a[href*="AAA"]') - Contains AAA

Assuming that you have a matching link (i.e., one that ends with AAA).

$('a[href="AAA"]:first').attr('title');

should work.

The reason that you are getting undefined for attr is that it isn't a jQuery object after you apply the indexer to the result of the query, it's the actual DOM element. To use attr, it needs to still be a jQuery object. Using the :first selector will reduce the results of the query to the first matching one. Since attr will return the value of the first matching attribute, it's not strictly necessary, but I think it makes the intent clearer. If you go to set the attribute value, attr will apply to all of the matching elements so, in that case, it's important -- thus I would use it in both places for clarity.

The way you've written it, you're looking for an href that ends with "AAA". Is that your intent?

• $= means "ends with"
• ^= means "starts with"
• ~= means "contains"
