<p>The <b>onclick</b> event occurs when the user clicks the left mouse button on an object. </p>

<p>This example uses the event to trigger a function that returns the event's <b>srcElement</b> <i>tagName</i> and <i>type</i>. </p>

<p>Click on each of the following objects and anywhere else on this document and see what has been clicked. </p>

<div align="center">
<p><input value="Click me" onclick="clickMe ( )"> &nbsp; 
<input type="button" value="Click me" onclick="clickMe ( )"> &nbsp; 
<a href="" onclick="clickMe ( )">Click me</a></p>

<p>What's been clicked: </p>
<p><input id="txtOutput" name="txtOutput"> &nbsp; <input id="txtOutput1" name="txtOutput1"></p>
