I currently have the following series of JQuery selectors:
$(this).parent().parent().children('a').children('img').attr('src')
It works just fine but is there a more compact way to do this?
UPDATE
Here's my HTML structure:
<div class="preview">
<a><img src="#"></a>
<div class="info">
<div class="item">This is where we start.</div>
<div>
</div>
不管您的具体标记如何,这都可以在您的初始条件下实现:
$(this).parent().siblings('a').children('img').attr('src')
You could do something like:
$(this).closest('.preview').find('a img').attr('src')
With that HTML, one way would be:
$(this).parents(".preview").find("a img").attr("src");
You could also easily:
$(this).parent().prev().children("img").attr("src");
Although, if you can make use of HTML5, my suggestion would be to add a data-ref to the start element div as follows:
<div class="item" data-ref="#imgID-1">This is where we start.</div>
// and of course add an id to the img
<img id="imgID-1" src="blah.png" />
Then you can easily recall as:
var source = $($(this).data("ref")).attr("src");
