如何执行多个同时的jquery效果？

Question

我正在为页面上的一些错误/验证元素设置动画.我想让它们反弹并突出显示,但如果可能的话,同时也要突出显示.这是我目前正在做的事情:

var els = $(".errorMsg");
els.effect("bounce", {times: 5}, 100);
els.effect("highlight", {color: "#ffb0aa"}, 300);

这导致元素首先反弹,然后突出显示,我希望它们同时发生.我知道.animate()您可以queue:false在选项中指定,但我不想使用动画,因为预先构建的效果"反弹"和"突出显示"正是我想要的.

我试过简单地将这些调用链接起来els.effect().effect(),但这不起作用.我也尝试queue:false输入我传入的选项对象,但这不起作用.

Answer 1

jQuery UI默认会对效果进行排队.使用dequeue()同时运行:

    var opt = {duration: 7000};

    $('#lbl').effect('highlight', opt).dequeue().effect('bounce', opt);   

在JsFiddle演示

好的,所以这是一个结合了反弹和高光效果的非常自定义的解决方案.我宁愿看到某些jquery支持更轻松地组合这些,指定{queue:false},但我认为它不那么简单.

我做的是拿jquery.effects.bounce.js和jquery.effects.highlight.js(来自jquery-ui-1.8rc3),并结合DaveS建议的两个代码,创建一个名为"hibounce"的新效果".在我的测试中,它支持两者的所有选项,并且它们同时发生.看起来不错!我不是一个巨大的像这样虽然解决方案的粉丝,因为维护系数.无论何时我升级jquery.ui,我都必须手动更新这个文件.

无论如何,这是组合结果(jquery.effects.hibounce.js)

(function($) {

$.effects.hibounce = function(o) {
    return this.queue(function() {
        // Highlight and bounce parts, combined
        var el = $(this),
            props = ['position','top','left','backgroundImage', 'backgroundColor', 'opacity'],
            mode = $.effects.setMode(el, o.options.mode || 'show'),
            animation = {
                backgroundColor: el.css('backgroundColor')
            };

        // From highlight
        if (mode == 'hide') {
            animation.opacity = 0;
        }

        $.effects.save(el, props);

        // From bounce
        // Set options
        var mode = $.effects.setMode(el, o.options.mode || 'effect'); // Set Mode
        var direction = o.options.direction || 'up'; // Default direction
        var distance = o.options.distance || 20; // Default distance
        var times = o.options.times || 5; // Default # of times
        var speed = o.duration || 250; // Default speed per bounce
        if (/show|hide/.test(mode)) props.push('opacity'); // Avoid touching opacity to prevent clearType and PNG issues in IE


        // Adjust
        $.effects.save(el, props); el.show(); // Save & Show
        $.effects.createWrapper(el); // Create Wrapper
        var ref = (direction == 'up' || direction == 'down') ? 'top' : 'left';
        var motion = (direction == 'up' || direction == 'left') ? 'pos' : 'neg';
        var distance = o.options.distance || (ref == 'top' ? el.outerHeight({margin:true}) / 3 : el.outerWidth({margin:true}) / 3);
        if (mode == 'show') el.css('opacity', 0).css(ref, motion == 'pos' ? -distance : distance); // Shift
        if (mode == 'hide') distance = distance / (times * 2);
        if (mode != 'hide') times--;

        // from highlight
        el
            .show()
            .css({
                backgroundImage: 'none',
                backgroundColor: o.options.color || '#ffff99'
            })
            .animate(animation, {
                queue: false,
                duration: o.duration * times * 1.3, // cause the hilight to finish just after the bounces (looks best)
                easing: o.options.easing,
                complete: function() {
                    (mode == 'hide' && el.hide());
                    $.effects.restore(el, props);
                    (mode == 'show' && !$.support.opacity && this.style.removeAttribute('filter'));
                    (o.callback && o.callback.apply(this, arguments));
                    el.dequeue();
                }
            });

        // Animate bounces
        if (mode == 'show') { // Show Bounce
            var animation = {opacity: 1};
            animation[ref] = (motion == 'pos' ? '+=' : '-=') + distance;
            el.animate(animation, speed / 2, o.options.easing);
            distance = distance / 2;
            times--;
        };
        for (var i = 0; i < times; i++) { // Bounces
            var animation1 = {}, animation2 = {};
            animation1[ref] = (motion == 'pos' ? '-=' : '+=') + distance;
            animation2[ref] = (motion == 'pos' ? '+=' : '-=') + distance;
            el.animate(animation1, speed / 2, o.options.easing).animate(animation2, speed / 2, o.options.easing);
            distance = (mode == 'hide') ? distance * 2 : distance / 2;
        };
        if (mode == 'hide') { // Last Bounce
            var animation = {opacity: 0};
            animation[ref] = (motion == 'pos' ? '-=' : '+=')  + distance;
            el.animate(animation, speed / 2, o.options.easing, function(){
                el.hide(); // Hide
                $.effects.restore(el, props); $.effects.removeWrapper(el); // Restore
                if(o.callback) o.callback.apply(this, arguments); // Callback
            });
        } else {
            var animation1 = {}, animation2 = {};
            animation1[ref] = (motion == 'pos' ? '-=' : '+=') + distance;
            animation2[ref] = (motion == 'pos' ? '+=' : '-=') + distance;
            el.animate(animation1, speed / 2, o.options.easing).animate(animation2, speed / 2, o.options.easing, function(){
                $.effects.restore(el, props); $.effects.removeWrapper(el); // Restore
                if(o.callback) o.callback.apply(this, arguments); // Callback
            });
        };
        el.queue('fx', function() { el.dequeue(); });
        el.dequeue();
    });
};

})(jQuery);

它现在可以像任何其他效果一样使用:

var el = $("#div1");
el.effect("hibounce", {color: "#F00", times: 5}, 100);
