Js中的一个日期处理格式化函数

Posted 2020-08-09

 1 //日期时间原型增加格式化方法
 2 
 3 Date.prototype.Format = function (formatStr) {
 4     var str = formatStr;
 5     var Week = [‘日‘, ‘一‘, ‘二‘, ‘三‘, ‘四‘, ‘五‘, ‘六‘];
 6 
 7     str = str.replace(/yyyy|YYYY/, this.getFullYear());
 8     str = str.replace(/yy|YY/, (this.getYear() % 100) > 9 ? (this.getYear() % 100).toString() : ‘0‘ + (this.getYear() % 100));
 9     var month = this.getMonth() + 1;
10     str = str.replace(/MM/, month > 9 ? month.toString() : ‘0‘ + month);
11     str = str.replace(/M/g, month);
12 
13     str = str.replace(/w|W/g, Week[this.getDay()]);
14 
15     str = str.replace(/dd|DD/, this.getDate() > 9 ? this.getDate().toString() : ‘0‘ + this.getDate());
16     str = str.replace(/d|D/g, this.getDate());
17 
18     str = str.replace(/hh|HH/, this.getHours() > 9 ? this.getHours().toString() : ‘0‘ + this.getHours());
19     str = str.replace(/h|H/g, this.getHours());
20     str = str.replace(/mm/, this.getMinutes() > 9 ? this.getMinutes().toString() : ‘0‘ + this.getMinutes());
21     str = str.replace(/m/g, this.getMinutes());
22 
23     str = str.replace(/ss|SS/, this.getSeconds() > 9 ? this.getSeconds().toString() : ‘0‘ + this.getSeconds());
24     str = str.replace(/s|S/g, this.getSeconds());
25     return str;
26 }

调用的时候比较简单,

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