<h2>Adding some JavaScript</h2>
<p>We can add events (that can call a JavaScript) to the &lt;area&gt; tags inside the 
image map. The &lt;area&gt; tag supports the onClick, onDblClick, onMouseDown, 
onMouseUp, onMouseOver, onMouseMove, onMouseOut, onKeyPress, onKeyDown, onKeyUp, 
onFocus, and onBlur events.</p>
<p>Here's the above example, with some JavaScript added:</p>

<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3" id="table14">
  <tr>
    <td valign="top">
	<pre>&lt;html&gt;
&lt;head&gt;
&lt;script type=&quot;text/javascript&quot;&gt;
function writeText(txt)
{
document.getElementById(&quot;desc&quot;).innerHTML=txt;
}
&lt;/script&gt;
&lt;/head&gt;</pre>
	<pre>&lt;body&gt;
&lt;img src=&quot;planets.gif&quot; width=&quot;145&quot; height=&quot;126&quot;
alt=&quot;Planets&quot; usemap=&quot;#planetmap&quot; /&gt;

&lt;map id =&quot;planetmap&quot; name=&quot;planetmap&quot;&gt;
&lt;area shape =&quot;rect&quot; coords =&quot;0,0,82,126&quot;
onMouseOver=&quot;writeText('The Sun and the gas giant
planets like Jupiter are by far the largest objects
in our Solar System.')&quot;
href =&quot;sun.htm&quot; target =&quot;_blank&quot; alt=&quot;Sun&quot; /&gt;

&lt;area shape =&quot;circle&quot; coords =&quot;90,58,3&quot;
onMouseOver=&quot;writeText('The planet Mercury is very
difficult to study from the Earth because it is
always so close to the Sun.')&quot;
href =&quot;mercur.htm&quot; target =&quot;_blank&quot; alt=&quot;Mercury&quot; /&gt;

&lt;area shape =&quot;circle&quot; coords =&quot;124,58,8&quot;
onMouseOver=&quot;writeText('Until the 1960s, Venus was
often considered a twin sister to the Earth because
Venus is the nearest planet to us, and because the
two planets seem to share many characteristics.')&quot;
href =&quot;venus.htm&quot; target =&quot;_blank&quot; alt=&quot;Venus&quot; /&gt;
&lt;/map&gt; 

&lt;p id=&quot;desc&quot;&gt;&lt;/p&gt;

&lt;/body&gt;
&lt;/html&gt;</pre>
