I'm trying to select an id that changes on different posts of same page. So the they have been given an id="show_posts_{PostID}" - on the final output the {PostID} is replaced with a number. In the function I need to call $('show_posts_XXXXXX') - XXXXXX being the generated ID. I have stored this ID in a variable called postId.

But I can't seem to do this $("'" + "show_posts_" + postId + "'")

Can anyone tell me how I can add a string to the end of a selector?
