Javascript resize image width

[sastro]

Here is my code

 

<script type="text/javascript">
function resize(id,va)
{
document.getElementById(id).width = va ;
}
</script>
<img src="https://www.google.com/logos/classicplus.png" id="img" height="100%">
<script type="text/javascript">resize('img','50%');</script>

 

Its not working to resize the image with % but worked without %.

I need to resize image width with persentage.

 

Please help

Percentages only work in CSS rules.

document.getElementById(id).style.width = va;
