You've probably been to sites like RapidShare and MegaUpload that allow you to download files but make you wait a specified number of seconds before giving you the download link. I've created a similar script but my script allows you to animate the CSS font-size of each second and present a reward at the end.
您可能去过RapidShare和MegaUpload等网站，这些网站可以下载文件，但需要等待指定的秒数才能提供下载链接。 我创建了一个类似的脚本，但是我的脚本允许您动画化每秒CSS 字体大小 ，并在最后给出奖励。
jQuery JavaScript (The jQuery JavaScript)
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() {
//where do we start?
if(!to && to != settings.endNumber) { to = settings.startNumber; }
//set the countdown to the starting number
jQuery(this).text(to).css("fontSize",settings.startFontSize);
//loopage
jQuery(this).animate({
fontSize: settings.endFontSize
}, settings.duration, "", function() {
if(to > settings.endNumber + 1) {
jQuery(this).css("fontSize", settings.startFontSize).text(to - 1).countDown(settings, to - 1);
}
else {
settings.callBack(this);
}
});
});
};
样品用量 (Sample Usage)
jQuery("#countdown").countDown({
startNumber: 10,
callBack: function(me) {
jQuery(me).text("All done! This is where you give the reward!").css("color", "#090");
}
});
The script is very customizable and the settings are self-explanatory.
该脚本是非常可定制的，并且设置是不言自明的。
