2021-7-30 11:17:07

createTime: this.getdateTime(),
    
    getdateTime() {
          var _this = this;
          let yy = new Date().getFullYear();
          let mm = new Date().getMonth() + 1;
          let dd = new Date().getDate();
          let hh = new Date().getHours();
          let mf =
            new Date().getMinutes() < 10
              ? "0" + new Date().getMinutes()
              : new Date().getMinutes();
          let ss =
            new Date().getSeconds() < 10
              ? "0" + new Date().getSeconds()
              : new Date().getSeconds();
          let gettime = yy + "-" + mm + "-" + dd + " " + hh + ":" + mf + ":" + ss;
          return gettime;
        },

定义方法(Vue获取当前日期)

method:{
    		  getdate() {
    		      var date = new Date();
    		      var seperator1 = "-";
    		      var year = date.getFullYear();
    		      var month = date.getMonth() + 1;
    		      var strDate = date.getDate();
    		
    		      if (month >= 1 && month <= 9) {
    		        	month = "0" + month;
    		      }
    		      if (strDate >= 0 && strDate <= 9) {
    		      	  strDate = "0" + strDate;
    		      }
    		      var currentdate = year + " 年 " + month + " 月 " + strDate + " 日 ";
    		      return currentdate;
    	    }
    	}
    
    
    调用方法
        {
       { getdate() }}
