Question

I am using jquery-ui and at some point I use the show and hide functions quite heavily to animate changing images coming in and out.

From some reason, after a few tries all of a sudden the controls on my page stop responding to clicks. After a bit of poking arround using firebug I discovered my page is filled with div’s of the class ui-effects-wrapper.

I have no idea why this happens or how to stop it. If I remove these divs I can no longer see the images I’ve been animating.

Any ideas?

ui-effects-wrapper was added by jquery UI effect plugin.

Here is some code taken from jquery.effects.core.js:

// Wraps the element around a wrapper that copies position properties
createWrapper: function(element) {

    // if the element is already wrapped, return it
    if (element.parent().is('.ui-effects-wrapper')) {
        return element.parent();
    }

    // wrap the element
    var props = {
            width: element.outerWidth(true),
            height: element.outerHeight(true),
            'float': element.css('float')
        },
        wrapper = $('<div></div>')
            .addClass('ui-effects-wrapper')
            .css({
                fontSize: '100%',
                background: 'transparent',
                border: 'none',
                margin: 0,
                padding: 0
            });

    element.wrap(wrapper);
    wrapper = element.parent(); //Hotfix for jQuery 1.4 since some change in wrap() seems to actually loose the reference to the wrapped element

    // transfer positioning properties to the wrapper
    if (element.css('position') == 'static') {
        wrapper.css({ position: 'relative' });
        element.css({ position: 'relative' });
    } else {
        $.extend(props, {
            position: element.css('position'),
            zIndex: element.css('z-index')
        });
        $.each(['top', 'left', 'bottom', 'right'], function(i, pos) {
            props[pos] = element.css(pos);
            if (isNaN(parseInt(props[pos], 10))) {
                props[pos] = 'auto';
            }
        });
        element.css({position: 'relative', top: 0, left: 0, right: 'auto', bottom: 'auto' });
    }

    return wrapper.css(props).show();
},
