vue组件中使用iframe元素

需要在本页面中展示vue组件中的超链接，地址栏不改变的方法:

<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" 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: [
{
name:'segmentFault',
link:'https://segmentfault.com/a/1190000004502619'
},
{
name:'博客',
link:'http://vuex.vuejs.org/'

4000
},
{
name:'特效',
link:'http://www.yyyweb.com/377.html'
}
]
}
},
mounted(){
const oIframe = document.getElementById('show-iframe');
const deviceWidth = document.documentElement.clientWidth;
const deviceHeight = document.documentElement.clientHeight;
oIframe.style.width = deviceWidth + 'px';
oIframe.style.height = deviceHeight + 'px';
},
methods:{
goBack(){
this.goBackState = false;
this.iframeState = false;
},
showIframe(){
this.goBackState = true;
this.iframeState = true;
}
}
}

</script>
<style scoped>

</style>

需要使同层元素不被覆盖，可以加

<iframe id="dialogFrame" frameborder="0" scrolling="no" style="background-color:transparent; position: absolute; z-index: -1; width: 100%; height: 100%; top: 0;left:0;"></iframe>

不过html5有新的dialog元素用于对话框。iframe的一些方法：获取iframe内容：

var iframe = document.getElementById("iframe1");
var iwindow = iframe.contentWindow;
var idoc = iwindow.document;
console.log("window",iwindow);//获取iframe的window对象
console.log("document",idoc);  //获取iframe的document
console.log("html",idoc.documentElement);//获取iframe的html
console.log("head",idoc.head);  //获取head
console.log("body",idoc.body);  //获取body

自适应 iframe:即1去掉滚动条，2设置宽高

var iwindow = iframe.contentWindow;
var idoc = iwindow.document;
iframe.height = idoc.body.offsetHeight;

例子：

<iframe id="google_ads_frame2" name="google_ads_frame2" width="160" height="600" frameborder="0" src="target.html" marginwidth="0" marginheight="0" vspace="0" hspace="0" allowtransparency="true" scrolling="no" allowfullscreen="true"></iframe>
