Hi,

I have an aspx page http://www.fast-drinks.com/Categories.aspx - There are various categories eg Spirits, Wines, beer - but within each category there are sub categories eg for Spirits you have Gin, Vodka, Whiskey etc.

The Category is being displayed in the html via the variable <%=SuperCats%> (I'm presuming this is an ASP (or ASP.Net) variable - I'm new to this!). What I want to do is depending on this value to display a different image. If you go to the above page you will see a grey bar with no content about 2 inches down the page. I want to put one image in this bar if <%=SuperCats%> is Spirits and another if its Wine and another if its Champagene, and anther if its Gifts, and anotherif .........................

I am presuming a JavaScript if statement will do the job - I just don't know how to implement it as the page is being rendered, as I am relatively new to the whole web development side of things - I normally do console apps.

THis is the code black I have at the moment

<tr height="22" style="background-image:url(images/front_end_site_images/sort_bar.gif)">
<td colspan="2">

<SCRIPT LANGUAGE="JAVASCRIPT" TYPE="TEXT/JAVASCRIPT">
if (<%=SuperCats%>=="Gift Ideas")
{
document.write('<img src="images/front_end_site_images/giftideas.gif">');
}
else if (<%=SuperCats%>=="Champagnes")
{
document.write('<img src="images/front_end_site_images/champagne.gif">');
}
else
{
document.write("hi...test..nothing done");
}
</SCRIPT>

<td>
</tr>

Your help is appreciated in any way shape or form.

Thanks and Best Regards

You can do this via the Select Case statement, for example:


Select Case SuperCats
Case "Gift Ideas"
srcImage = "images/front_end_site_images/giftideas.gif"
Case "Champagnes'
srcImage = "images/front_end_site_images/champagne.gif"
Case Else
srcImage = "images/front_end_site_images/defaultimage.gif"
End Select

Now, I'm not sure exactly where you need to put that. Is SuperCats a database lookup value that defaults to something on the page load? If so, you could put this in your Page_Load subroutine. Depends on how you want your page to function. Anyway, hope this helps.

BTW, it would be helpful if you used the forum code tags when posting code. :)
