I use method like below. But when all datebox have input, it also have error msgs.
Can validate without a form? Just like jquery Easyui.

Code:

<Form ref="form" :model="user" :rules="rules" @validate="errors=$event">
  <div style="margin-bottom:20px" v-for="(item, index) in user.task">
    <DateBox name="startTime" v-model="item.startTime"></DateBox>
    <span class="error">{{getError('startTime')}}</span>
  </div>
  <div style="margin-bottom:20px">
    <LinkButton :disabled="false" @click="submitForm()">Submit</LinkButton>
  </div>
</Form>


data() {
  return {
    user: {
      task: [{startTime: null},{startTime: null},{startTime: null}]
    },
    rules: {
      startTime: "required"
    },
    errors: {}
  };
},

I use this method now, but I also want to show the total pageNumber.

You can custom the page layout, define your page components freely.

Code:

<DataGrid
  style="height:250px"
  :pagination="true"
  :data="data"
  :total="total"
  :pageSize="pageSize"
  :pagePosition="pagePosition"
  :pageLayout="['first','prev','tpl','next','last','info']"
  :pageNumber="pageNumber"
  @pageChange="pageNumber=$event.pageNumber"
>
  <template slot="tpl" slot-scope="{datagrid}">
    <NumberBox v-model="pageNumber" style="width:80px"></NumberBox>
  </template>

In locale there is a pagination settings: beforPageText、afterPageText, but both them not used. Why not provide a textbox and jump button like the jQuery EasyUI？
