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)

 效果

	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;
	    }
	}

//  获取当前日期前后多少天的日期，多少天前传正数，多少天后传负数，今天传0，

//  num为传入的数字， time为传入的指定日期，如果time不传，则默认为当前时间

getBeforeDate(num, time) {
            let n = num;
            let d = '';
            if(time) {

            let year = d.getFullYear();
            let mon = d.getMonth() + 1;
            let day = d.getDate();
            if(day <= n) {
                if(mon > 1) {
