javascript - How to block ads from third-party pages embedded in iframes?

Question

Embed a third-party parser (a player) on the playback page. On the mobile playback page - there is an advertisement with a height of 93 and an adaptive width at the bottom of the player ~ as shown, the advertisement is very eye-catching, please help, how to block it, or Is it possible to directly use JS to prevent this ad from loading?

Answer 1

If it is a third-party page, then the iframe embeds a webpage with a different domain name. The browser has security restrictions and is not allowed to access this page. I would like to think about whether there is a way to embed a webpage address that does not contain advertisements

Answer 2

You can remove it with $("#iframe的ID").contents().find("#iframe中的广告ID").remove()

Answer 3

Generally speaking, there are cross-domain problems when operating embedded iframes,

没有跨域问题用 js方法 获取iframe里面的对象 来操作是可取的；

有跨域问题，用两个层来做控制，外层包iframe和p：

<p style="position:relative;height:200px;width:400px;border:1px solid red;">
    <iframe src="http://netnr.com" style="position:absolute;width:100%;height:100%"></iframe>
    <p style="position:absolute;bottom:0;left:0;right:0;height:93px;background-color:white;">
        已屏蔽广告
    </p>
</p>
