Example 1: onclick a tag

<script type='text/javascript'>
function check() {
    return false;

// The element id (TheElementID) and var name (myElement) can be named anything.
var myElement = document.getElementByID('TheElementID');
myElement.onclick = function() {
	// Carry out a function here...
}
