Question

Given the following jquery code..

jQuery.fn.sliding = function () {

    return this.each(function () {

        $(this).bind('ON_CONTENT_CHANGING', function (e) {
            $(this).block({
                overlayCSS: { opacity: 1, color: '#000' },
                timeout: 800
            });
        });

        $(this).bind('ON_CONTENT_CHANGED', function (e) {
            $(this).sliding();
            $(this).unblock();
        });

        var $panels = $(this).find('.scrollContainer > div');
        var $container = $(this).find('.scrollContainer');
        var $resized = $panels.css({ 'width': $(this).width() - 44 });



        // if false, we'll float all the panels left and fix the width 
        // of the container
        var horizontal = true;

        // float the panels left if we're going horizontal
        if (horizontal) {
            $panels.css({
                'float': 'left',
                'position': 'relative' // IE fix to ensure overflow is hidden
            });

            // calculate a new width for the container (so it holds all panels)
            $container.css('width', $panels[0].offsetWidth * $panels.length);
        }

        // collect the scroll object, at the same time apply the hidden overflow
        // to remove the default scrollbars that will appear
        var $scroll = $(this).find('.scroll').css('overflow', 'hidden');

        // handle nav selection
        function selectNav() {
            $(this)
            .parents('ul:first')
                .find('a')
                    .removeClass('selected')
                .end()
            .end()
            .addClass('selected');
        }

        $(this).find('.navigation').find('a').click(selectNav);


        // go find the navigation link that has this target and select the nav
        function trigger(data) {
            var el = $(this).find('.navigation').find('a[href$="' + data.id + '"]').get(0);
            selectNav.call(el);
        }

        if (window.location.hash) {
            trigger({ id: window.location.hash.substr(1) });
        } else {
            $('ul.navigation a:first').click();
        }

        // offset is used to move to *exactly* the right place, since I'm using
        // padding on my example, I need to subtract the amount of padding to
        // the offset.  Try removing this to get a good idea of the effect
        var offset = parseInt((horizontal ? $container.css('paddingTop') : $container.css('paddingLeft')) || 0) * -1;


        var scrollOptions = {
            target: $scroll, // the element that has the overflow

            // can be a selector which will be relative to the target
            items: $panels,

            navigation: '.navigation a',

            // allow the scroll effect to run both directions
            axis: 'xy',

            onAfter: trigger, // our final callback

            offset: offset,

            // duration of the sliding effect
            duration: 500,

            // easing - can be used with the easing plugin: 
            // http://gsgd.co.uk/sandbox/jquery/easing/ 
            easing: 'swing'
        };

        $(this).serialScroll(scrollOptions);
        $.localScroll(scrollOptions);

        scrollOptions.duration = 1;
        $.localScroll.hash(scrollOptions);

    });
};

Then this is the actual html file…

    $('#toggle').toggle(function (e) {
        if ($("#sidebar:animated, #canvas:animated").length) {
            e.preventDefault();
            return;
        }

        $(".ui-sliding").trigger('ON_CONTENT_CHANGING');


        $('#sidebar').hide('slide', { direction: 'right' }, 100, function () {

            $('#canvas').switchClass('span-17', 'span-24', 100, function () {
                $(".ui-sliding").trigger('ON_CONTENT_CHANGED');
                $('#toggle').switchClass('close', 'open');
            });
        })
    },
            function (e) {
                if ($("#sidebar:animated, #canvas:animated").length) {
                    e.preventDefault();
                    return;
                }


                $(".ui-sliding").trigger('ON_CONTENT_CHANGING');

                $('#canvas').switchClass('span-24', 'span-17', 100, function () {
                    $('#sidebar').show('slide', { direction: 'right' }, 100, function () {
                        $(".ui-sliding").trigger('ON_CONTENT_CHANGED');
                        $('#toggle').switchClass('open', 'close');
                    });
                });
            });

Is there any way to prevent the toggle from being fired again if someone clicks while it is performing the function?

I referenced Tell jQuery to ignore clicks during an animation sequence and the technique did not work.

Answer 1

You can do something like this, check if anything you animate is animating and cancel if so.

Put this at the top of each toggle function:

if($("#sidebar:animated, #canvas:animated").length) {
  e.preventDefault();
  return;
}
