force target =" _self" iframe中动态extrnal跨域的问题

问题描述

我在Chrome上使用iframe在kiosk模式上有一个网站，其中我打开了外部网站的数量。并且每个站点都有自己的target =_ blank链接。我无法控制这些外部链接。
我想只打开iframe中的所有外部链接，或者我需要为那些target = _blank链接发布一些消息。我无法在自助服务终端上打开新窗口。我到目前为止已经搜索过，发现它必须是一些服务器端编码。 Javascript对此没有任何帮助。

I have a site on kiosk mode on chrome using iframe in which I am opening number of external sites. And each of the sites has their own links with target="_blank". I have no control on those external links.I want to open all those external links inside iframe only or I would need to publish some message for those target=_blank links. I can't open new window on kiosk. I have searched so far and found it has to be some server side coding. Javascript won't be any help in that.

我的iframe代码：

My iframe code:

  navigateToExternal:function(href)
    {
        Engine.ui.openMenu();
        Engine.ui.exit();
        Engine.ui.mostRecentSection = "external";

        $("a[data-navsection], a[href]").removeClass("disabled");
        $("a[href='" + href + "']").addClass("disabled");

        $(".footer").hide();

       var sandbox = "sandbox=\"allow-forms allow-scripts allow-same-origin\"";


         $("#content-container").append("<iframe id=\"contentFrame\" src=" + href + "\"" + sandbox + "></iframe>");
    },

任何帮助或建议真的很棒。

Any help or suggestion would be really great.

提前致谢!!

推荐答案

您不能，父页面无法访问跨网站iframe，iframe无法访问跨网站的父网页。

You can't, the parent page can't access the cross-site iframe and the iframe can't access the cross-site parent page.

这属于Same-Origin策略并不能在客户端进行解决。你可以在服务器上抓取这些网站并将它们作为你自己的网站展示，但是我不确定它会有多么有效。

This falls under the Same-Origin policy and can't be worked-around on the client-side. You could scrape those sites on the server and present them as your own, however I'm not sure how effective that will be.
