jquery Checking to see if element has element

Question

I'm using jquery 1.3 and is trying to duplicate the 1.4 .has functionality.

I need to check if the .page element contains the image, and if it doesn't, append it.

Is it something like:

var imageid = thirdimage; if ($('#page:has(#'+imageid+')') === undefined) { $('#page').append($('#'+imageid)); }

Thanks.

the has() selector has been available since 1.1.4 according to the doc. And I've used it specifically in 1.3.2. Are you sure this isn't some other issue? Maybe try $('#page').find('#'+imageid) === undefined — Jim Schubert
