<template>
 <div class="accept-container">
   <div class="go-back" v-show="gobackstate" @click="goback">goback</div>
<ul>
 <li v-for="item in webaddress">
  <a :href="item.link" rel="external nofollow" target="showhere" @click="showiframe">{{item.name}}</a>
 </li>
</ul>
<iframe v-show="iframestate" id="show-iframe" frameborder=0 name="showhere" scrolling=auto src=""></iframe>
 </div>
</template>
<script>
export default {
 name: 'hello',
 data () {
 return {
  iframestate:false,
  gobackstate:false,
  webaddress: [
