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?
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)
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.
just use $("#show_posts_"+postID)
Two things.
To select an element with a given
ID, you need a # character at the
beginning of the ID.
Don't add the quotes to the beginning and end of the string.
Thus:
$('#show_posts_' + postId)
