这次给大家带来js如何格式化时间日期,下面就是实战案例,一起来看一下。

// 对Date的扩展,将 Date 转化为指定格式的String
// 月(M)、日(d)、小时(h)、分(m)、秒(s)、季度(q) 可以用 1-2 个占位符,
 // 年(y)可以用 1-4 个占位符,毫秒(S)只能用 1 个占位符(是 1-3 位的数字) 
 // 例子:
  // (new Date()).Format("yyyy-MM-dd hh:mm:ss.S") ==> 2006-07-02 08:09:04.423 
  // (new Date()).Format("yyyy-M-d h:m:s.S")      ==> 2006-7-2 8:9:4.18
   Date.prototype.Format = function (fmt) { //author: meizz 
    var o = {    
        "M+": this.getMonth() + 1, //月份 
        "d+": this.getDate(), //日 
        "h+": this.getHours(), //小时 
        "m+": this.getMinutes(), //分 
        "s+": this.getSeconds(), //秒 
        "q+": Math.floor((this.getMonth() + 3) / 3), //季度 
        "S": this.getMilliseconds() //毫秒     }; 
    if (/(y+)/.test(fmt)) {
        fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
    }   
     for (var k in o)     
        if (new RegExp("(" + k + ")").test(fmt)) 
            fmt = fmt.replace(RegExp.$1, (RegExp.$1.length == 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));  
              return fmt;   
}
//调用:
 var time1 = new Date().Format("yyyy-MM-dd");
 var time2 = new Date().Format("yyyy-MM-dd hh:mm:ss");
