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,index) in webAddress" :key="index">
                <a :href="item.link" target="showHere" @click="showIframe"></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:'简书',
                    link:'https://www.jianshu.com/u/c90f05f0ab2b'
                }
            ]
        }
    },
    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>
<!-- Add "scoped" attribute to limit CSS to this component only -->
<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>
