Jquery resize function help?

Hello all. Here's the situation. I would like to display my "main" container div at 100% of the window width and height. There will be other content below the fold, so a simple 100% height in the CSS won't work. I have used some JavaScript to remedy this as you can see below. My problem is that upon window resizing, the script needs to grab the new window height and adjust the container div accordingly. Unfortunately, the resize event isn't triggering anything, and I see no errors in the console. The div only resizes again upon page reload.

Sorry, I'm still a JavaScript newb! Any help would be most appreciated. Thanks.

$( document ).ready(function() {
    var $winHeight = $( window ).height();
    $( ".container" ).css({'height' : $winHeight});

    $( window ).resize(function() {
        $( ".container" ).css({'height' : $winHeight});
    });
});

The problem is that your $winHeight variable is set when the page loads. You need to bind a variable to the window height inside of the resize() method as well:

$( document ).ready(function() {
    var $winHeight = $( window ).height();
    $( ".container" ).css({'height' : $winHeight});

    $( window ).resize(function() {
        var $newHeight = $( window ).height();
        $( ".container" ).css({'height' : $newHeight});
    });
});
