I'm trying to do a rating system like the one that rates movies on blockbuster.com. I'm doing a .net application and want to use the stars as image buttons and when the image button is clicked have some database interactivity happen. My problem is the mousover issue. I'm currently using the .Attributes("onmouseover") to highlight the star that I am on. But let's say someone hovers over the fourth start, I want stars one through four to highlight. How do I make this happen? Do I need a combination of javascript and vb.net? Please help!

After doing a quick google, I found this for you:

http://www.masugadesign.com/the-lab/scripts/unobtrusive-ajax-star-rating-bar/

It is designed for MySQL/PHP, but I'm certain you can just swap the PHP for .NET code.

This really isn't exactly what I want but thanks for the links.

To be more specific I have coded basically what I want but want the ability to change multiple imagebutton images based on what imagebutton is hovered over. I don't know if I can do this via .net/javascript or what.

Sounds like JavaScript to me, example:


<script>
function showStars(str) {
if (str == 1)
{
getElementById('star_1').src = 'star_on.jpg';
} else if (str == 2)
{
getElementById('star_1').src = 'star_on.jpg';
getElementById('star_2').src = 'star_on.jpg';
}
}

function hideStars(str) {
if (str == 1)
{
getElementById('star_1').src = 'star_off.jpg';
} else if (str == 2)
{
getElementById('star_1').src = 'star_off.jpg';
getElementById('star_2').src = 'star_off.jpg';
}
}
</script>

I'm not very good with javascript but here is my code, I haven't been able to get it to work. I would also like to do this with <input type=image>'s. Is this possible?

<script>
function showStars(str) {
if (str == 1)
{
getElementById('star_1').src = 'images/lil_boxing_glove.gif';
} else if (str == 2)
{
getElementById('star_1').src = 'images/lil_boxing_glove.gif';
getElementById('star_2').src = 'images/lil_boxing_glove.gif';
}
}

function hideStars(str) {
if (str == 1)
{
getElementById('star_1').src = 'images/no_boxing_glove.gif';
} else if (str == 2)
{
getElementById('star_1').src = 'images/no_boxing_glove.gif';
getElementById('star_2').src = 'images/no_boxing_glove.gif';
}
}
</script>

</head>

<body>

<table border="0" cellpadding="0" cellspacing="0">
 
<tr>  
   <td><img name="star_1" onMouseOut="hideStars(1);" onMouseOver="showStars(1);" src="images/no_boxing_glove.gif" width="20" height="30" border="0">
   </td>
   <td><img name="star_2" onMouseOut="hideStars(2);" onMouseOver="showStars(2);" src="images/no_boxing_glove.gif" width="20" height="30" border="0">
   </td>  
</tr>
</table>
