If statements and vars help please :o

Ok so I used to do some flash so I know with JQuery its kind of the same thing with some differences So ill explain what I plan to do in more of a actionscript set up.....

I plan to make a small game for my Gf's sister (she still believes in Santa)

Heres what I need do to

So ill have a var called Points in comp ready :

var Points = 0;

Then It will be a click function So lets say I have a DIV called Santa and it is clicked I want it to do this:

var Points = +1; so it adds 1

then sym.$("Santa").hide();

next would be the If statement

Something like this:

if (Points = 3)

    {

       Do somthing

      }

How would i go about this in Edge/Jquery? my jquery coding know how sucks

Thanks in advance for any help.
