Your code is correct and getting the element by the selector check it here, you need to check following.

var id = 3;
alert($("#d" + id).html()); // shows some thing is here... in alert.

@user3672518 Who should check it is you, not someone who's trying to help you. Check the comments in your question. There's a `jsFiddle` link with the actual code working. – emerson.marini May 30 '14 at 11:00
When you say "Your code is correct", the existing code does nothing you can see (it just obtains a JQuery element then discards it) :) – iCollect.it Ltd May 30 '14 at 11:04
The statement "this is not working" does not gives any clear hint that what is happening? you might be getting some error that can help in finding the solution – Adil May 30 '14 at 11:06
I check the console and it give error "Uncaught Error: Syntax error, unrecognized expression: #d4" " – user3672518 May 31 '14 at 11:10
