How to insert metatag without using jquery append?

Question

I used the following jquery to insert a metatag into a html document.

Answer 1

You can also use "setAttribute" (rather than the "dot" notation) for weirdo attribute names (that contain non-alpha-numeric characters).

Example:

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

The example above causes IE (<=9) to always use the latest document standards mode. Sometimes IE will fall back to older standards, and therefore break your modern javascript / canvas web app.
