How to add string to jQuery selector?

Question

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 re

Answer 1

just use $("#show_posts_"+postID)

Answer 2

You need to include the '#' character at the start of the string.

$('#show_posts_' + postId)

Also, you're trying to stuff the quotes in there in your example, and that doesn't make sense.

Answer 3

Should work. If it does, you'll kick yourself. Don't forget the hash for the ID, and the extra quotation marks aren't necessary.

$("#show_posts_" + postId)

Answer 4

Two things.

1. To select an element with a given ID, you need a # character at the beginning of the ID.

2. Don't add the quotes to the beginning and end of the string.

Thus:

$('#show_posts_' + postId)
