jQuery if statement depending on width in px

Question

I'm quite new to jQuery, could someone please tell me if I have expressed the above 'if' statement correctly? I basically want something to run if the width of my variable equals 900px. My variable is var $brewapp = $('#brewapp');

Thanks.

if (($brewapp).width == '900px')
{
//what i want it to do
}

Answer 1

.width is a function, that returns a number. So your test should look like this:

if ($brewapp.width() === 900)

I suggest the Mozilla Javascript docs if you want to deepen your JS knowledge.

Answer 2

You need to add only two characters:

if ($brewapp.width() == 900)
{
//what i want it to do
}
