Internet Explorer issue with HTML5 form attribute for button element

Question

in HTML5, there is the form attribute. Basically

Answer 1

As far as I can tell, Internet Explorer does not (up to IE10, at least) support the form attribute.

You can either polyfill this in javascript, or move the input to sit inside the relevant form. This has already been answered elsewhere though: https://stackoverflow.com/a/16694990/13019
