静态调用必须要Date.today() 酱紫
动态方法 的 调用
var today=new Date();
today.add({});如此
其中我还自己添加了两个方法 用于动态获取第几周的功能
Date.prototype.getWeekOfYear = function() {//这天在本年是第几周 var onejan = new Date(this.getFullYear(), 0, 1); return Math.ceil((((this - onejan) / 86400000) + onejan.getDay() + 1) / 7); }; Date.prototype.getWeekOfMonth=function () {//这天在本月是第几周 var day = this.getDate(); //get weekend date day += (this.getDay() == 0 ? 0 : 7 - this.getDay()); return Math.ceil(parseFloat(day) / 7); };
PS:一个月最多能有6个周序
