JavaScript OnMouseOver for Firefox

JavaScript OnMouseOver for Firefox

I wrote a fairly simple JavaScript line to modify the size of an image when there is a OnMouseOver  event. And then wrote a similar line of JavaScript to reduce the size back to normal on the OnMouseOut event. The only problem is the JavaScript didn't work on FireFox although it was great with Internet Explorer. After some research I found that using the 'this' object was needed with FireFox. So I adjusted my code to also have the events in the image object itself. Here is the code:


<div align="center">
<table border="0" cellpadding="0" cellspacing="0" height="700px" width="215px">
    <tr height="140px" width="195px" align="center">
    <td><a href="AboutUs.aspx" 
        onmouseover="document.getElementById('AboutUs').style.width='205px'; document.getElementById('AboutUs').style.height='112px'" 
        onmouseout="document.getElementById('AboutUs').style.width='195px'; document.getElementById('AboutUs').style.height='105px'">
        <img border="0" alt="About Us" src="/Images/Home/AboutUs.gif" style="height: 105px; width:195px; position: static;" id="AboutUs" 
        onmouseout="'195px';'105px'" />

Amazing blog! Why can't you write for our blog :(.

Interesting idea and well implement but would it not be better to swap images instead, replacing the smaller one with a bigger one?<br><br>That way you'd not get any image quality issues with resizing.

So does this work on Firefox and IE?<br><br>If so it could be a neat solution.<br>

From my understanding it should work on both browsers

Thanks for sharing the codes. I've been having the same problem when I'm using both Firefox and Internet explorer. I hope this time that both will work.
