I want to add <meta http-equiv="X-UA-Compatible" content="IE=edge"> for a particular page.

But my pages are rendered inside one HTML tag. Only the content is changing on clicking different templates. So i cannot add the <meta> in <HEAD> section.

Is there any way to add the <meta http-equiv="X-UA-Compatible" content="IE=edge"> using javascript ?

You can't do meta tags with JavaScript. You can add the tag to the template or you can set the header from the HTTP server. – Soberminded

@Dontfeedthecode I seriously doubt that that answer actually works. – Soberminded

You can add it:

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.

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. :-| )

I can confirm that adding the meta tag dynamically doesn't work in IE8. – Montero
I've been able to force Quirks instead of IE 7 Standards by replacing the whole document content using document.write. Perhaps there's a way to create a new document object in IE8 and replace the current document with that new one, which hopefully will trigger a reevaluation of the document mode. The createDocument function isin't available in IE8, but I guess we could rely on an iframe to create a new document instance. – Montero
IE sucks.No use of this in IE because as soon as page rendering is started n thing is specified or there is a conflict IE take a stand in favor the dead man i.e. IE7. – Cape
Can I use document.head.appendChild() instead? – Gittel
@Gittel - If your browser supports it, yes. I think all modern ones do. – Sergias

$('head').append('<meta http-equiv="X-UA-Compatible" content="IE=Edge" />');

or

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

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.

This may allow other meta tags, if you're lucky

Additional HEAD tags can be placed into Page Settings > Advanced Settings > Page Header Tags.

Like this ?

<script>
var meta = document.createElement('meta');
meta.setAttribute('http-equiv', 'X-UA-Compatible');
meta.setAttribute('content', 'IE=Edge');
document.getElementsByTagName('head')[0].appendChild(meta);
</script>

You don't need setAttribute for this, both httpEquiv and content are reflected. – Sergias

As specified by @marcellothearcane, for modern browser, you can also use:

var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.head.appendChild(meta);

Supported browser here: document.head

Try

document.head.innerHTML += '<meta http-equiv="X-UA-..." content="IE=edge">'

To get started, create your standard HTML boilerplate with a DOCTYPE, html, head, and body, then add a meta tag for the charset. Add a title element and use the text RPG - Dragon Repeller for it. Include a link tag for your stylesheet to link the styles.css file.

Finally, create a div element with id set to game within your body.change in code
