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)); 
    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());
