Add JQuery variable to $('.class').html(“HTML”);

Question

I'm trying to isolate one element by it's class but I need part of the class name to be from a variable as every element has a unique name.

div class="post6453"
div class="post9845"
div class="post2345"

var id = $(this).attr("id"); (ID = 6453, 9845, 2345 for example)

if(data == 1){
            $('post+ID').html("Html goes here");
            }else{
            $('post+ID').html("Html goes here");
            }

I hope this makes sense. Thanks.

Answer 1

your variable is id (lowercase) and not ID . Even your variable concatenation is not correct. Try with

$('.post' + id).html(...)

Answer 2

if element is unique you should use ID="" instead :

i think this is the jQuery selector

$(".post"+id).html("Html goes here");
