Can I use variables inside getelementbyid()?

Question

Consider there is a div element with id "div_id"
Let variable A = div_id.
then
is getElementById("div_id") equivalent to getElementById(A)?

Answer 1

Hi Adnan
yes, variable needs to be a string

but you probably want to do something like this
getElementById("div_id"+a);

So you get div_id1, div_id2. etc
