Jquery Change Height based on Browser Size/Resize

Question

I was wondering if there was a way to determine the height/width of a browser. What i'm trying to do is set a height on a div to 500px when the browser size is 1024x768, and for anything lower i'd like to set it to 400px.

Thanks in advance

Answer 1

If you are using jQuery 1.2 or newer, you can simply use these:

$(window).width();
$(document).width();
$(window).height();
$(document).height();

From there it is a simple matter to decide the height of your element.

Answer 2

$(function(){
    $(window).resize(function(){
        var h = $(window).height();
        var w = $(window).width();
        $("#elementToResize").css('height',(h < 768 || w < 1024) ? 500 : 400);
    });
});

Scrollbars etc have an effect on the window size so you may want to tweak to desired size.

Building on Chad's answer, you also want to add that function to the onload event to ensure it is resized when the page loads as well.

jQuery.event.add(window, "load", resizeFrame);
jQuery.event.add(window, "resize", resizeFrame);

function resizeFrame() 
{
    var h = $(window).height();
    var w = $(window).width();
    $("#elementToResize").css('height',(h < 768 || w < 1024) ? 500 : 400);
}

Answer 4

Pay attention, there is a bug with Jquery 1.8.0, $(window).height() returns the all document height !

Answer 5

I have the feeling that the check should be different

new: h < 768 || w < 1024
