jQuery: Get id from selector which is inside a variable

I have a #pdfcontainer which is inside divs #main and #pdfmain. I'm using a variable, because I use the same div many times:

var $pdfcontainer = $('#main #pdfmain #pdfcontainer');

Inside the #pdfcontainer I have #delete which I want to access for various reasons. So how do I get it using the variable and without typing the whole $('#main ...') all over again? I don't just want to use selector $('#delete') because on my site it's much slower that way.

Thnx 开发者_如何转开发already!

Specify $pdfcontainer as context to your selector like this:

$("#delete", $pdfcontainer)

Make sure that you have only one item with unique ids, for example, you should have id #delete assigned to only one element.

$($pdfcontainer + " #delete") should work, if you declare your variable as a string var $pdfcontainer = "#id #id2 #id3";. Using the variable in place of the actual string doesn't mean you can't add more to the string.

$pdfcontainer.find('#delete');

try this..

$pdfcontainer.find('#delete'); 

you can use pdfcontainer.find("#delete) enjoy!
