javascript variables containg jquery api evaluated at calling or assignment time?

If i assign a variable something like this

var a = $("input").val();

At the start of the program. And then call something like this :

$("div").html(a);

Will this print the value of the value which was the value in the input when the var a = $("input").val(); was executed or when the line : $("div").html(a); was executed ?

The first line (var a = $("input").val();) sets the value of a variable to whatever data is available. Later on when you use that variable (a), it will be the same value. It is only a string, it is not the actual DOM element.

a will contain the value when you first assigned it so the that value will be set in the div html

It will print the value that it had when you first assigned it.

Edit: If you want to work with its current value, just evaluate it each time:

$("div").html( $("input").val() );
