JavaScript实现的一个日期格式化函数分享
由于在工作中,经常需要对日期进行格式化,不像后端那样,有方便的方法可调用,可以在date的对象prototype中定义一个format方法,见如下:
//日期时间原型增加格式化方法 Date.prototype.Format=function(formatStr){ varstr=formatStr; varWeek=['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)); varmonth=this.getMonth()+1; str=str.replace(/MM/,month>9?month.toString():'0'+month); str=str.replace(/M/g,month);
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()); returnstr; }
