document.getElementById not working even if I ve ID present in my css

Question

I tried searching but didnt get a valid answer to my question. I always get \"null\" when I call document.getElementById(\"#\"+id) and it alerts Document

Answer 1

document.getElementById() does not need the pound (#) symbol.

Answer 2

While you're using JavaScript, you don't use # sign to reference the ID of the element.

Your code for

alert("#"+id);

Would be

alert(id);

You need # Number sign, only when working with CSS or jQuery.
