iView 是一套基于Vue.js的开源UI组件库,主要服务于PC界面的中后台产品。

1、iView的特性

1) 高质量、功能丰富
2) 友好的API ,自由灵活地使用空间
3) 细致、漂亮的 UI
4) 事无巨细的文档
5) 可自定义主题

2、iView的安装:

1) 使用npm:

npm install --save iview

2) CDN引入:

<link rel="stylesheet" href="css/iview.css" rel="external nofollow" >
<script src="js/iview.min.js"></script> 

由于公司项目需要,所以目前捣鼓了vue+iview搭建了一个项目,用的环境都是1.0版本,在使用iview弹框中,由于需要先进行弹框中表单的验证,验证通过才调用后台接口,但是呢,iview弹框中的确定按钮点击一下弹框就消失了,怎么办,要实现效果,各种翻看资料,最终解决办法如下:

<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">
       <div class="fade-transition ivu-form-item-error-tip error" style="display:none;position: static">验证码错误</div>
      </i-col>
      <i-col span="3" style="margin-left:5px;">
          <i-button type="primary" :loading="loadingBtn" @click="toLoading">
            <span v-if="!loadingBtn">{{btnText}}</span>
            <span v-else>{{btnText}}</span>
          </i-button>
      </i-col>
    </Row>
  </Modal>
</template>
<script type="text/javascript">
import {
  orderService
} from 'jo'
  export default {
    props:["show"],
    data(){
      return {
        loading:true,
        loadingBtn:false,//点击申请取消按钮后loading
        btnText:'申请取消订单',
        code:"",//验证码
        clearTime:"",//定时器
        countDownIndex:60,//60秒倒计时
      }
    },
    methods:{
      codeBlur(){
        if(this.code == ""){
          $(".errorInput").css("border","1px solid red")
          $(".error").css("display","block")
        }else{
          $(".errorInput").css("border","1px solid #d7dde4")
          $(".error").css("display","none")
        }
      },
       toLoading(){
          //调用发送验证码接口
   //      let operName = window.sessionStorage.getItem("userName")
            // accountService.recommenderGetCode(operName,this.selectDelteOne.recommender,1)
          this.countDown()

      },
      countDown(){
          //倒计时
          var that = this;
          that.loadingBtn = true
          that.btnText = that.countDownIndex+"秒"
          that.countDownIndex--;
          that.clearTime = setInterval(function(){
            console.log(that.countDownIndex)
            if(that.countDownIndex == 0){
                that.countDownIndex = 60
                that.btnText = "发送"
                that.loadingBtn = false
                window.clearTimeout(that.clearTime)
              return false
            }
             that.btnText = that.countDownIndex+"秒"
             that.countDownIndex--;
          },1000)
         // }
      },
      asyncOK(){
        //提交
        if(this.code == ""){
          this.show = true
          console.log('sdasda'+this.show)
          $(".errorInput").css("border","1px solid red")
          $(".error").css("display","block")
          this.loading = false
          this.$nextTick(() => { this.loading = true;});
          return
        }
        this.$nextTick(() => {this.loading = true; });
         // let operId = window.sessionStorage.getItem("crmUserId")
      //    let operName = window.sessionStorage.getItem("userName")
      //    if(this.isApply){
      //    orderService.sendSingleUpdate03(this.data, 3, operName, operId, this.code).then(res => this.updateList(res.message))
      //    }else{
      //     orderService.sendSingleUpdate03(this.data, 2, operName, operId, this.code).then(res => this.updateList(res.message))
      //    }
      }
    }
  }
</script>

大概思路就是先命名一个变量loading,这里必须为true,然后在点击弹框的提交按钮的时候先把loading设置为false,然后必须加上

this.$nextTick(() => { this.loading = true;});就能实现效果啦,具体实现原理,这坑遇到了,就先记录下来
