How to add string to jQuery selector?

I am trying to select an identifier that changes to different posts on the same page. Thus, they were assigned id = "show_posts_ {PostID}" - at the final output {PostID} is replaced by a number. In the function I need to call $('show_posts_XXXXXX') - XXXXXX - the generated identifier. I saved this identifier in a variable called postId.

But I can not do this $("'" + "show_posts_" + postId + "'")

Can someone tell me how can I add a line to the end of the selector?

Must work. If this happens, you will kick yourself. Do not forget the hash for the identifier, and additional quotation marks are not needed.

 $("#show_posts_" + postId)

You need to indicate the character "#" at the beginning of the line.

 $('#show_posts_' + postId)

Also, you are trying to write quotes 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 the # symbol at the beginning of the identifier.

  • Do not add quotation marks at the beginning and end of a line.

Thus:

 $('#show_posts_' + postId)
+1
source share
