element[].value

what does "var element = document.getElementById('IDNAME');" "var num = element.elements[0].value;" do? I dont understand the part "element[0].value? and why it is an array?

First, would you share the question and the code, together? And maybe what class it was for? :)

it's just a self study for ping pong test.

when I want to ask user to enter a number and I want to restore the number in a variable that change the sting to an integer. I see that people dont use ParseInt(), and they just use element[].value
