Question

I’m working on a landing page for my web app, and I’m using some sort of modal boxes I built.
It uses some jQuery to display the box itself and the overlay.
There are 3 modal boxes on the same page that you can open with one link for each box.

My code works really well (even though it seems heavy [I’m not a pro in Javascript but I always give a try as much as I can]). But when I close the modal box, the overlay slides out as it’s supposed to do but the animation repeats 3 times (probably because of the code for the 3 modal box).

So, my code is fully online there → http://graphix.net23.net/app/

Here’s the jsFiddle for you to play 🙂 → http://jsfiddle.net/EY59T/ (the bug isn’t really visible, you can only see the overlay takes a while to get away)

I already tried the .stop() function. It solves the problem when you display the first modal, but after when you click on another modal, the overlay doesn’t come.

Look at my heavy code:

// iOS Modal
$("a#modal-open").click(function () {
      $("div#modal-ios").show("fade", 600);
      $("div.modal-overlay").show("slide", 300);
      $(".app h4").hide("fade", 300);
      $("div.app").animate({backgroundPositionY:-120}, 600);
      return false;
});
$("a#modal-done,div.modal-overlay").click(function () {
      $("div#modal-ios").hide("fade", 600);
      $("div.modal-overlay").hide("slide", 300);
      $(".app h4").show("fade", 600);
      $("div.app").animate({backgroundPositionY:0}, 600);
      return false;
});
$( document ).on( 'keydown', function ( e ) {
    if ( e.keyCode === 27 ) {
        $("div#modal-ios,div.modal-overlay").hide("fade", 300);
        $(".app h4").show("fade", 300);
        $("div.app").animate({backgroundPositionY:0}, 600);
    }
});
// END iOS Modal
// Android Modal
$("a#modal-open-android").click(function () {
      $("div#modal-android").show("fade", 600);
      $("div.modal-overlay").show("slide", 300);
      return false;
});
$("a#modal-done,div.modal-overlay").click(function () {
      $("div#modal-android").hide("fade", 600);
      $("div.modal-overlay").hide("slide", 300);
      return false;
});
$( document ).on( 'keydown', function ( e ) {
    if ( e.keyCode === 27 ) {
        $("div#modal-android,div.modal-overlay").hide("fade", 300);
    }
});
// END Android Modal
// WP Modal
$("a#modal-open-wp").click(function () {
      $("div#modal-wp").show("fade", 600);
      $("div.modal-overlay").show("slide", 300);
      return false;
});
$("a#modal-done,div.modal-overlay").click(function () {
      $("div#modal-wp").hide("fade", 600);
      $("div.modal-overlay").hide("slide", 300);
      return false;
});
$( document ).on( 'keydown', function ( e ) {
    if ( e.keyCode === 27 ) {
        $("div#modal-wp,div.modal-overlay").hide("fade", 300);
    }
});
// END WP Modal​

It’s been two days I’m working on it and still can’t find a working solution, help me please 🙂

EDIT: you can close the modal with three different ways: click on button, click on overlay or ESC key. Note that the bug doesn’t happen with the ESC key.

Answer 1

The problem is that you are binding the closing handlers three times one for each type of model you open. but you bind those on the same elements a#modal-done,div.modal-overlay. This way when you click on it, it starts 3 fades on the same elements and that messes it up.

You need to apply the handler only once, and just add the fading of all popups in there..

Also by adding a common class to your links that are for opening the popups, you can target those in a single pass as well

These will simplify your code to

// method to hide any open popup and the overlay
function closePopupOverlay() {
    // hide all popups - will only really work with the currently open one
    $("#modal-ios,#modal-wp,#modal-android,div.modal-overlay").hide("fade", 500);

    $(".app h4").show("fade", 500);
    $("div.app").animate({
        backgroundPositionY: 0
    }, 600);
}
$(document).on('keydown', function(e) {
    if (e.keyCode === 27) {
        closePopupOverlay();
    }
});
$("a#modal-done,div.modal-overlay").click(function() {
    closePopupOverlay();
    return false;
});
// when we click on one of the links 
$('.model-open').click(function() {
    var target = this.id.replace('-open-', '-'); // find the related popup id
    $('#' + target).show("fade", 600); // show the related popup
    $("div.modal-overlay").show("slide", 300); // show the overlay

    if (target === 'modal-ios') { // handle the special needs of the ios button
        $(".app h4").hide("fade", 300);
        $("div.app").animate({
            backgroundPositionY: -120
        }, 600);
    }

    return false;
});

The html change is that i added class="model-open" to your 3 links and also changed the id for the ios link to modal-open-ios to conform with the other two, so we can easily extract what popup we want to open..
