点击元素的jQuery孩子

Question

我有一个链接列表，这些链接附有点击事件，我需要从孩子那里获得ID链接。因此，在下面的示例中，如果我单击了我需要Google重新调整的第一个列表元素。

我试过了 '$this a' 但是不能完全弄清楚语法。

$("ul li").click(function(event){
  $("input").val($(this).html());             
});

<ul>
    <li><a href="http://www.google.com" id="google">Google</a>
</ul>

Answer 1

我看不到样本html，但是

$(this).find('a:first').attr('id')

会这样做（修复 答：首先 选择器如果不是您的意思）

Answer 2

To make your code a little neater, lets bind triggers with functions like so: (i suggest you give your UL an ID so it is specific to only elements within that UL)

$('ul li').bind('click', getAnchorId);

The function that is called (getAnchorId) gets the ID attribute of the children element (a) of the clicked element (ul li) and applies it to a variable (anchorId), and to show its getting the correct info I put the result in an alert.

function getAnchorId() {
    var anchorId = $(this).children('a').attr('id');
    alert(anchorId);
}

Now u can do what ever u wish with that variable :)

hope this helps :)

Answer 3

You could use the children method:

$(this).children('a').eq(0).attr('id');

I'm not sure about the syntax, but something like this should work.
