How to add meta tag in javascript
提问by Snehanjali Sahoo
I want to add <meta http-equiv="X-UA-Compatible" content="IE=edge">for a particular page.
我想<meta http-equiv="X-UA-Compatible" content="IE=edge">为特定页面添加。
But my pages are rendered inside one HTMLtag. Only the content is changing on clicking different templates. So i cannot add the <meta>in <HEAD>section.
但是我的页面是在一个HTML标签内呈现的。单击不同的模板时，只有内容会发生变化。所以我不能添加<meta>in<HEAD>部分。
Is there any way to add the <meta http-equiv="X-UA-Compatible" content="IE=edge">using javascript?
有没有办法添加<meta http-equiv="X-UA-Compatible" content="IE=edge">using javascript？

You can add it:
你可以添加它：
var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.getElementsByTagName('head')[0].appendChild(meta);
...but I wouldn't be surprised if by the time that ran, the browser had already made its decisions about how to render the page.
...但如果在运行时浏览器已经决定如何呈现页面，我不会感到惊讶。
The real answer here has to be to output the correct tag from the server in the first place. (Sadly, you can't just not have the tag if you need to support IE. :-| )
这里真正的答案必须是首先从服务器输出正确的标签。（遗憾的是，如果您需要支持 IE，您不能没有标签。:-|）

$('head').append('<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
');
$('head').append('<meta http-equiv="X-UA-Compatible" content="IE=Edge" />
');
or
或者
var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.getElementsByTagName('head')[0].appendChild(meta);
Though I'm not certain it will have an affect as it will be generated after the page is loaded
虽然我不确定它会产生影响，因为它会在页面加载后生成
If you want to add meta data tags for page description, use the SETTINGS of your DNN page to add Description and Keywords. Beyond that, the best way to go when modifying the HEAD is to dynamically inject your code into the HEAD via a third party module.
如果要为页面描述添加元数据标签，请使用 DNN 页面的设置来添加描述和关键字。除此之外，修改 HEAD 的最佳方法是通过第三方模块将代码动态注入 HEAD。

This may allow other meta tags, if you're lucky
如果幸运的话，这可能允许使用其他元标记
Additional HEAD tags can be placed into Page Settings > Advanced Settings > Page Header Tags.
可以将其他 HEAD 标签放入页面设置 > 高级设置 > 页眉标签。
