如何异步加载具有document.write的第三方javascript标记 [英] How to load third-party javascript tag asynchronously which has document.write

问题描述

我们发布了一段javascript代码，例如< script src =http://ours.com/some.js>< / script> 哪些网站所有者在 http://example.com 上放置了他们的网站，在这个javascript标记中我们想要动态地包含第三方js其中可以包含document.write，但当然如果我们尝试通过常规方法包含它，

  var script_tag =使用document.createElement（ '脚本'）; 
 script_tag.type ='text / javascript'; 
 script_tag.src =http://third-party.com/some.js; 
 document.getElementById（'target'）。appendChild（script_tag）; 
  

我们从浏览器收到警告，

警告：从异步加载的
外部脚本调用document.write（）被忽略。

我们如何解决这个问题？请记住，我们并不真正控制第三方脚本，因此我们无法更改其中的逻辑。我们正在寻找一种适用于所有浏览器的解决方案。

解决方案

在已加载的文档上加载脚本的问题（而不是让浏览器忽略 document.write（））是你要删除所有现有的HTML。请参阅此示例，以便了解具体情况或更多信息。有关document.write（）方法的详细信息，请参阅文档页面。

虽然我知道这可能不是你期望得到的答案，但我相信你运气不好，因为重写脚本不是一种选择。 / p>

出现此与类似的回复是类似的问题。

We give out a piece of javascript tags such as <script src="http://ours.com/some.js"></script> which site owners put on their site like http://example.com and in this javascript tag we want to dynamically include a third-party js such as which can have document.write in it, but of course if we try to include it by conventional method,

var script_tag = document.createElement('script');
script_tag.type = 'text/javascript';
script_tag.src="http://third-party.com/some.js";
document.getElementById('target').appendChild(script_tag);

we get a warning from browser,

Warning: A call to document.write() from an asynchronously-loaded external script was ignored.

How do we get around this? Keep in mind, we don't really have control over third-party scripts so we can't change the logic in it. We are looking for some solution which can work across all browsers.

解决方案

The problem with loading a script on a already loaded document (instead of having the browser ignore the document.write()) is that you would delete all existent HTML. See this example so you can understand exactly what's happening, or for more details look at a documentation page for the document.write() method.

While I know this might not be what you're expecting to get as an answer, I believe you are out of luck since rewriting the script is not an option.
