thank you for helping..

Have you searched yet? It's extremely trivial to search by ID... — BoltClock, Apr 06 '11 at 05:12

If you're contextually within the element with id="reface-more-btn", you can select it intuitively like this:

$(this).parent().parent().find('#read-more');

If you're looking for readability, try this:

$(this).closest('#read-more');

But since the id is unique to only one element, why aren't you just using $('#read-more');?

You might be confusing class and id, as only one element can have a certain id, while many elements can share a class. Read this question for a longer explanation, as it's essential to know the differences: div class vs id.

@Jeff: He states "to be applied for more than one button", even thought *that* is wrong. – Mikael Östberg Apr 06 '11 at 05:17
The OP might be confusing `id` and `class`. – Blender Apr 06 '11 at 05:17
if the OP already has a JQuery command that he is calling on the button maybe he just wants to chain that with what he wants to do with #read-more, so he saves a line and avoids searching the DOM – Porco Apr 06 '11 at 05:19

This will always work:

$("#read-more");

Given that the structure will always look like it does:

var theSpan = $(this).parent().parent().find('#read-more');

var selector = $('#read-more');

It is globally unique since it is has an ID.

EDIT: Try

$(this).parent().prev();

Well, selecting an element by id is quite easy.

$("#read-more")

Will do it regardless of where you are because the id's are global.

@Blender, I know, but that is what he is asking. But I think your answer pretty much covers that as well. – Mikael Östberg Apr 06 '11 at 05:51
I'm saddened by OP's who don't conceptually understand HTML and want to use jQuery. There should be a test that should be taken before being allowed to download the library... – Blender Apr 06 '11 at 05:53
