vue组件中使用iframe元素

Posted 2020-10-04 梦见一只电子羊

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/‘
        },
        {
          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>
