html - Check if a browser has built-in HTML5 form validation?

How to check if a browser has built-in HTML5 form validation ability? By doing so, we don't need to apply jQuery form validation functions on browsers who can validate form by themselves.

[Solved] Based on ThinkingStiff's answer, here is a way:

if (typeof document.createElement("input").checkValidity == "function") {
    alert("Your browser has built-in form validation!");
}

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
};
