如何阻止iframe里引入的html自动跳转

问题: 在页面中用iframe引入别的页面链接，但它会跳转到这个引入的链接上

原因：引入的html中有 if (top.location != self.location) {top.location=self.location;} 使用这段代码后，会自动判断当前的location是否是顶层的，即是否被嵌套到iframe里面了，如果是，则强制跳转。

解决：

1、</p> <p>即增加两个：security="restricted" sandbox=""（内嵌百度时要允许弹框，即sandbox="allow-popups"），前者是IE的禁止js的功能，后者是HTML5的功能。刚好就可以让IE，Chrome，Firefox这三大浏览器都实现了禁止iframe的自动跳转.</p> <p>2、还有一种：用双重iframe可以阻止强制跳转,使用<iframe><iframe></ifame></ifame> 第一层的iframe会覆盖了第二层的，把第一层的做成透明的，然后第二层嵌套目标网页。</p> <p>第一种方便好用。</p> </div>  <div class="p-2"></div> <div class="arcinfo my-3 fs-7 text-center"> <a href='/t/etagid3388-0.html' class='tagbtn' target='_blank'>iframe</a><a href='/t/etagid334-0.html' class='tagbtn' target='_blank'>js</a> </div> <div class="p-2"></div> </div> <div class="p-2"></div>  <div class="lbox p-4 shadow-sm rounded-3"> <div class="boxtitle"><h2 class="fs-4">相关</h2></div> <hr> <div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-566383.html">在虚拟机(centos)上安装或卸载nodejs</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-565889.html">js 正则匹配两个字符串之间，某个字符串之前（之后）的内容</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-565764.html">sql server2016里面的json功能 - 转</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-565466.html">cefSharp通过js操控页面，含跨域操控</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-565101.html">angularjs $emit $on $broadcast 父子兄弟之间传值</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-564929.html">渡一 3-2 js基础知识</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-563799.html">js 校验身份证号码</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-563694.html">nodejs 一个简单的web服务器，用于前端自己快速测试部署</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-563449.html">11-15.JS轮播、专辑、放大镜</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-562181.html">JS值传递与引用传递</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-562341.html">[转]Vue-cli3.x引入本地json报404 解决方案</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div><div class="row g-0 py-2 border-bottom align-items-center"> <div class="col-7 col-lg-11 border-lg-end"> <h3 class="fs-6 mb-0 mb-lg-2"><a href="/a/1-562100.html">extjs ajax 同步及 confirm 确认提示框问题</a></h3> <div class="ltag fs-8 d-none d-lg-block"> </div> </div> </div>   </div>  </div> <div class="col-lg-3 col-12 p-0 ps-lg-2">     <div class="lbox p-4 shadow-sm rounded-3"> <div class="boxtitle pb-2"><h2 class="fs-4"><a href="#">标签</a></h2></div> <div class="clearfix"></div> <ul class="m-0 p-0 fs-7 r-tag"> </ul> <div class="clearfix"></div> </div>  </div> </div> </div> </main> <div class="p-2"></div> <footer> <div class="container-fluid p-0 bg-black"> <div class="container p-0 fs-8"> <p class="text-center m-0 py-2 text-white-50">一品网 <a class="text-white-50" href="https://beian.miit.gov.cn/" target="_blank">冀ICP备14022925号-6</a></p> </div> </div> <script> var _hmt = _hmt || []; (function() { var hm = document.createElement("script"); hm.src = "https://hm.baidu.com/hm.js?6e3dd49b5f14d985cc4c6bdb9248f52b"; var s = document.getElementsByTagName("script")[0]; s.parentNode.insertBefore(hm, s); })(); </script> </footer> <script src="/skin/bootstrap.bundle.js"></script> </body> </html>
