复制代码 代码如下:
$(document).ready(function () {
/* 延迟函数 */
jQuery.fn.delay = function (time, func) {
return this.each(function () {
setTimeout(func, time);
});
};
jQuery.fn.countDown = function (settings, to) {
settings = jQuery.extend({
startFontSize: '36px',
endFontSize: '12px',
duration: 1000,
startNumber: 10,
endNumber: 0,
callBack: function () { }
}, settings);
return this.each(function () {
if (!to && to != settings.endNumber) { to = settings.startNumber; }
//设定倒计时开始的号码
$(this).text(to).css('fontSize', settings.startFontSize);
//页面动画
$(this).animate({
'fontSize': settings.endFontSize
}, settings.duration, '', function () {
if (to > settings.endNumber + 1) {
$(this).css('fontSize', settings.startFontSize).text(to - 1).countDown(settings, to - 1);
}
else {
settings.callBack(this);
}
});
});
};
//使用
$('#countdown').countDown({
startNumber: 10,
callBack: function (me) {
$(me).text('All done! This is where you give the reward!').css('color', '#090');
}
});
});
