Js中的一个日期处理格式化函数

 

  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) {
    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));
    var month = 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());
    return str;
}

 

调用的时候比较简单,

比如

var d=new Date();
var str=d.Format("yyyy-MM-dd  hh:mm:ss");
console.log(str);
