Two methods to capture a resize event on a window, but how to capture the event once the user has finished resizing the window? A little trick is to use a setTimeout() with clearTimeout() and optimal duration is 250 even captures slowish window resizes smoothly. See Window resize examples for how you might use them.

Method 1

$(window).bind('resize', function(e)
     //do something

Method 2

$(window).resize( function(e)
    //do something

Method 2 with timeout

$(window).bind('resize', function(e)
        window.resizeEvt = setTimeout(function()
            //code to do after window is resized
        }, 250);

    Great solutions!

    Why do you have the resize listener twice on “method 2 with timeout” ?
    $(window).bind(‘resize’, function(e)….

      I wish you got an answer. I too wonder why. I can’t get the code to work properly and I wonder if this is why. :(

        I have no idea why the author used bind and resize. It looks like a mistake to me.
        In any case, using modern jQuery syntax, this should do what you want:

        var resizeEvt;
        $(window).on("resize", function() {
        resizeEvt = setTimeout(function() {
        }, 250);

        If you want to discuss this some more, why not post a question in our JavaScript forum?

    Method 2 with timeout does the trick–thanks.

    I made a couple minor changes: I declared resizeEvt in the parent scope (i.e. outside the .bind() call). This way it avoids putting a variable in the global namespace in case I want to apply this method elsewhere.

    One more change was to use .on() instead of .bind(), which is now the preferred way of attaching an event handler.
