Question

I want to use the html5 element <input type="number"> on my website, but i want to know what happens to this field in browsers that do not support this feature? Is it than a classic <input type="text"> field for those browsers?

Answer 1

When a browser does not recognize a particular type value for an <input>, it reverts to it’s default value, which is text. So, all of the following are equivalent on browsers that do not support type="number":

<input type="number">
<input type="somevaluethatdoesntexist">
<input type="text">
<input>

For browsers that do support type="number", the number <input> will be displayed instead of the text <input>.
