jQuery实现抖动效果

//抖动效果
//intShakes：抖动次数；intDistance：抖动左右距离；intDuration：持续时间
jQuery.fn.shake = function (intShakes, intDistance, intDuration) {
    this.each(function () {
        var jqNode = $(this);
        jqNode.css({ position: 'relative' });
        for (var x = 1; x <= intShakes; x++) {
            jqNode.animate({ left: (intDistance * -1) }, (((intDuration / intShakes) / 4)))
            .animate({ left: intDistance }, ((intDuration / intShakes) / 2))
            .animate({ left: 0 }, (((intDuration / intShakes) / 4)));
        }
    });
    return this;
}

使用：

$('#tishi').shake(3, 20, 400);
