But its not working please help me with the html Code!
You're trying to set the top of an element with the id demo, which is a <div>. I assume that div doesn't have position:absolute set on it so won't move anywhere, and I guess you want the <img> to move and and not the <div> anyway. If you remove the id from the <div> and add it to the <img> (like in your second piece of code above) you shouldn't have any problems. This code should work:
<html>
<head>
<script type="text/javascript">
function changepic()
{
document.getElementById("demo").style.top=2000 + "px";
}
</script>
</head>
<body>
<h1>My First Web Page</h1>
<div>
<img id="demp" src="./omna.jpg" style="position:absolute; left: 400; top: 100; width: 200; height: 200;"/>
</div>
<button type="button" onclick="changepic()">change pic</button>
</body>
</html>
You setting the inline style of the image and then setting the top of the div. Either do one or the other. Or better still just remove the div, add an id to your and set it's style.
<img id="image" src="./omna.jpg" style="position:absolute; left: 400; top: 100; width: 200; height: 200;" />
document.getElementById("image").style.top=2000;
加载中,请稍侯......
