Due to the needs of the company's project, I have currently built a project with vue iview. The environment used is version 1.0. I am using the iview pop-up box. , since the form in the pop-up box needs to be verified first, the background interface will be called only after the verification is passed. However, the pop-up box disappears after clicking the OK button in the iview pop-up box. What should I do? To achieve the effect, browse the information in various ways , the final solution is as follows:

<template> 
  <!--取消订单弹框和老板批准弹框--> 
   <Modal 
    :visible.sync="show" 
    title="提示" 
    :loading="loading" 
    @on-ok="asyncOK"> 
    <Row> 
      <i-col span="3"></i-col> 
      <i-col span="1" style="color:red;margin-top:7px;font-weight: bold">*</i-col> 
      <i-col span="2" style="margin-top:5px;">授权码</i-col> 
      <i-col span="6"> 
       <input class="ivu-input errorInput" type="number" v-model="code" placeholder="请输入" @blur="codeBlur"> 
       <p class="fade-transition ivu-form-item-error-tip error" style="display:none;position: static">验证码错误</p> 
      </i-col> 
      <i-col span="3" style="margin-left:5px;"> 
          <i-button type="primary" :loading="loadingBtn" @click="toLoading">

The general idea is to first name a variable loading, which must be true, and then when clicking the submit button of the pop-up box, first set loading to false, and then you must add

this.$nextTick(() => { this.loading = true;}); can achieve the effect. The specific implementation principle. If you encounter this pitfall, record it first
