<h2>What Can JavaScript Do?</h2>
<h3> Author : Mangulu patra </h3>
<p>JavaScript can change HTML attribute values.</p>

<p>In this case JavaScript changes the value of the src (source) attribute of an image.</p>

<img id="myImage" src="pic_bulboff.gif" style="width:100px">
<button class="on" onclick="Runbulb()">Button</button>



<script>
var ison=false;
function Runbulb(){
if(ison==true)
{
document.getElementById('myImage').src='pic_bulboff.gif';
ison=false;
}
else{
document.getElementById('myImage').src='pic_bulbon.gif';
ison=true;
}

}
</script>

</body>
</html>
