主要用到了这个 属性 picker-options 

html

  <el-date-picker v-model="timeData" type="datetimerange" range-separator="至" start-placeholder="开始日期" end-placeholder="结束日期" format="yyyy-MM-dd HH:mm" value-format="timestamp" @change="getSTime"  :picker-options="pickerOptions" ></el-date-picker>

js

data(){
    return{
         pickerOptions: {
           disabledDate: (time) => {
             return this.dealDisabledDate(time);
            }
        }
        }
    }
methods:{
 dealDisabledDate(time) {
      var times = Date.now()
      return time.getTime() > times;
  }
}
