问题描述

嗨亲爱的程序员

在这个jquery代码我用来计算3个月仍然启动网页，我不知道jquery语言，我怎么能设置变量来计算3个月或90天

hi dear programmers
in this jquery code i use to be calculate the 3 month remain to start the web page, i don't know jquery language as well, how can i set variable to calculate the 3 month or 90 days

(function($) {
	$.fn.ccountdown = function(_yr, _m, _d, _t) {
		var $this = this;
		var _montharray = new Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec")
		var _today = new Date();
		// calling function first time so that it wll setup remaining time
		var _changeTime = function() {
			var _today = new Date();
			var _todayy = _today.getYear();
			if (_todayy < 1000)

				_todayy += 1900;

			var _todaym = _today.getMonth();

			var _todayd = _today.getDate();

			var _todayh = _today.getHours();

			var _todaymin = _today.getMinutes();

			var _todaysec = _today.getSeconds();

			_todaysec = "0" + _todaysec;

			_todaysec = _todaysec.substr(_todaysec.length - 2);

			var _todaystring = _montharray[_todaym] + " " + _todayd + ", " + _todayy + " " + _todayh + ":" + _todaymin + ":" + _todaysec;

			var _futurestring = _montharray[_m - 1] + " " + _d + ", " + _yr + " " + _t;

			/* calculation of remaining days, hrs, min, and secs */

			_dd = Date.parse(_futurestring) - Date.parse(_todaystring);

			_dday = Math.floor(_dd / (60 * 60 * 1000 * 24) * 1);

			_dhour = Math.floor((_dd % (60 * 60 * 1000 * 24)) / (60 * 60 * 1000) * 1);

			_dmin = Math.floor(((_dd % (60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) / (60 * 1000) * 1);

			_dsec = Math.floor((((_dd % (60 * 60 * 60 * 1000 * 24)) % (60 * 60 * 1000)) % (60 * 1000)) / 1000 * 1);

			var el = $($this);

			var $ss = el.find(".second"), $mm = el.find(".minute"), $hh = el.find(".hour"), $dd = el.find(".days");

			$ss.val(_dsec).trigger("change");

			$mm.val(_dmin).trigger("change");

			$hh.val(_dhour).trigger("change");

			$dd.val(_dday).trigger("change");

};

		_changeTime();

		setInterval(_changeTime, 1000);

	};

 

})(jQuery);
