How do I select an element in jQuery by using a variable for the ID?

Question

For example, the following selects a division with id=\"2\":

row = $(\"body\").find(\"#2\");

How do I do something like this:

r         


        

Answer 1

There are two problems with your code

1. To find an element by ID you must prefix it with a "#"
2. You are attempting to pass a Number to the find function when a String is required (passing "#" + 5 would fix this as it would convert the 5 to a "5" first)
