Custom JavaScript feature detection

(function() {

	// Create input element for testing
	var inputs = document.createElement('input');
	
	// Create the supports object
	var supports = {};
	
	supports.autofocus   = 'autofocus' in inputs;
	supports.required    = 'required' in inputs;
	supports.placeholder = 'placeholder' in inputs;

	// Fallback for autofocus attribute
	if(!supports.autofocus) {
		
	}
	
	// Fallback for required attribute
	if(!supports.required) {
		
	}

	// Fallback for placeholder attribute
	if(!supports.placeholder) {
		
	}
	
	// Change text inside send button on submit
	var send = document.getElementById('contact-submit');
	if(send) {
		send.onclick = function () {
			this.innerHTML = '...Sending';
		}
	}
