## Pick first option for a select element
$('select').val($('select>option:nth-child(1)').val());

## Find clicked LI element
$("ul.nav li").click(function () {
  alert(this.id); // id of clicked li by directly accessing DOMElement property
  alert($(this).attr('id')); // jQuery's .attr() method, same but more verbose
  alert($(this).html()); // gets innerHTML of clicked li
  alert($(this).text()); // gets text contents of clicked li
});

## Bootstrap - allow other element to trigger click of button for drop down menu

    <div class="btn-group">

	    if (!regex.test(key)) {
	       event.preventDefault();
	       return false;
	    }
 	});

## Input text box only accepts letters or digits
$('input').bind('keypress', function (event) {
