1.整個元件之間的通訊是通過 props ，可以是物件可以是陣列或者是函式
2.在需要的該元件的頁面使用 import DConfirm from ‘../components/confirm.vue’;引入該元件並註冊元件；

並且通過 v-bind指令繫結資料
3.在引入的頁面採用如下方法：

function abc(){
    this.$refs.myConfirm.showModel();
    this.confirmOptions= {
        type: "warning",
        title: "缺考學生",//提示
        message:this.locklist,
         btnCancelText:'關閉',
         btnSubmitText:'提交',
          btnCancelFunction:function(){
              console.log(333)
          },
          btnSubmitFunction:function(){
              console.log(1111)
          }
    }
}
