格式化时间日期-在Date上加prototype属性实现

//格式化时间日期的函数  年：YYYY，月：MM，日：DD,他们中间可以用任何字符来链接，例如：var date=new Date().Format('YYYY-MM-DD');下面代码可以作为common的js来在项目中用

(function ($) {

Date.prototype.Format = function (formatStr) {

var str = formatStr;

var Week = ['日', '一', '二', '三', '四', '五', '六'];

str = str.replace(/yyyy|YYYY/, this.getFullYear());

str = str.replace(/yy|YY/, (this.getYear() % 100) > 9 ? (this.getYear() % 100).toString() : '0' + (this.getYear() % 100));

str = str.replace(/MM/, this.getMonth() + 1 > 9 ? (this.getMonth() + 1).toString() : '0' + (this.getMonth() + 1).toString());

str = str.replace(/M/g, this.getMonth() + 1);

str = str.replace(/w|W/g, Week[this.getDay()]);

str = str.replace(/dd|DD/, this.getDate() > 9 ? this.getDate().toString() : '0' + this.getDate());

str = str.replace(/d|D/g, this.getDate());

str = str.replace(/hh|HH/, this.getHours() > 9 ? this.getHours().toString() : '0' + this.getHours());

str = str.replace(/h|H/g, this.getHours());

str = str.replace(/mm/, this.getMinutes() > 9 ? this.getMinutes().toString() : '0' + this.getMinutes());

str = str.replace(/m/g, this.getMinutes());

str = str.replace(/ss|SS/, this.getSeconds() > 9 ? this.getSeconds().toString() : '0' + this.getSeconds());

str = str.replace(/s|S/g, this.getSeconds());

return str;

}
