Question

I want to check in my website, if the visitors browser support a HTML5 input type. How should I do it?

Answer 1

With the form fields you can use this:

var i = document.createElement("input");
i.setAttribute("type", "color");
return i.type !== "text";

If color is supported, i.type will be color but if it’s not supported, the navigator returns text as default.
So a simple verification like this can help you.
