vue+iview实现分页及查询功能

<template>
 <div v-if="this.$store.state.user.usertype == 0 || this.$store.state.user.usertype == 1">
  <input type="text" search enter-button placeholder="根据施工人员姓名查找" v-model="peoplename" @input="search"/>
  <table width="100%" :columns="peoplecol" :data="peopledat"></table>
  <!--通过sync修饰符可以动态获取页码-->
  <page :total="datacount" :current.sync="current" :page-size="pagesize" show-total class="paging" @on-change="changepage"></page>
  
  <!--该modal是删除提醒框-->
  <modal v-model="confirmdelete" width="360">
   <p slot="header" style="color:#f60;text-align:center">
    <icon type="ios-information-circle"></icon>
    <span>删除确认</span>
   </p>
   <div style="text-align:center">
    <p>此操作不可恢复，确定要删除吗？</p>
   </div>
   <div slot="footer">
    <button size="large" @click="canceldelete">取消</button>
    <button type="error" size="large" @click="deleteconfirm">删除</button>
   </div>
  </modal>
 </div>
