Dynamically Assigned Event Handlers

• Assign a function as an event handler.
• Dynamically switch functions, change functionality.
• Define function, assign to handler.
• Note: the book used a Function, which refers to the Function object.  But this is not correct, you should still use function as we have in class.
• Example:

function keypress(e) {
     window.alert('Key pressed: ' + String.fromCharCode(e.which));
}
document.onkeypress = keypress;
