Check if a browser has built-in HTML form validation?

by

Simply check if the checkValidity() function exists:

Demo: http://jsfiddle.net/ThinkingStiff/cmSJw/

function hasFormValidation() {

    return (typeof document.createElement( 'input' ).checkValidity == 'function');

};

Call it like this:

if( hasFormValidation() ) {
    //HTML5 Form Validation supported
};
