I wonder if anyone can assist me with an issue I'm having?
I'm sort of new to the world of javascript, I have a page that pulls a list of records in asp, and I'm trying to past the varibles, and have them display a gallery of images.

Now I have no problem getting the QueryString passed onto the second page, and also have a piece of javascript read the QueryString, what I can't seem to do, is get onLoad to read the QueryString. Please find the code listed below;

<script type="text/JavaScript">
var Suffix
var Images
Suffix = "<%=Request.QueryString("Suffix")%>";
Images = "<%=Request.QueryString("Images")%>";

onLoad = "gallery('Suffix', 'Images');"
</script>

Can anyone point me in the right direction...

Where's the code for gallery()? What does the query string look like when this page loads?

the QueryString looks like;


As for the code for the gallery(); please find this listed below;

function gallery(picset, number)
{
var picsethtml=new Array()

picsethtml[0] = "<ul>";

for (i=1;i<=number;i++)
{
if (i/3 % 1 == 0){
picsethtml = '<li><a href="fullplate.asp?image='+picset+i+'" target="_blank" ><img src="../upload/gallery/'+picset+i+'.jpg" width="200" height="140" alt="click the thumbnail to enlarge"></a></li>';
}
else
{
picsethtml = '<li><a href="fullplate.asp?image='+picset+i+'" target="_blank" ><img src="../upload/gallery/'+picset+i+'.jpg" width="200" height="140" alt="click the thumbnail to enlarge"></a></li>';
}
}
picsethtml[number+1] = "</ul>";

document.getElementById('gallery').innerHTML = picsethtml.join("");
}

Thanks you for the prompt reply.

First, you have an extra semicolon in your query string, which will probably interfere with finding the Images variable.

You pass the character strings 'Images' and 'Suffix' to the gallery() function, but not the variables themselves.

I would also change
Code: 
if (i/3 % 1 == 0)
to
Code: 
if (i % 3 == 0)
to avoid potential floating point errors. Modulo arithmetic works with integers only, I believe, and not floating points.

However, there doesn't seem to be any difference in your code in the if and else statements, so I'm not sure why you have that conditional to begin with.

Thanks, sort of get what your saying. Then how do I pass the variables, rather than the characters strings???

As for the difference in the IF and Else statements, that should contain a reference to a blank image preset.

You're asking some real basic questions, so I'd recommend you do a Google search for Javascript tutorials.

And always copy and paste your code in here from the original so we can see exactly what the browser is working with.

>onLoad = "gallery('Suffix', 'Images');"
What do you mean by that? Maybe this?
[tt]onLoad = function() {gallery('<%=Request.QueryString("Suffix")%>';,'<%=Request.QueryString("Images")%>');}
[/tt]

tsuji, thanks that got me halfway there...

But now I'm getting an unknown error on line 20 of the function listed above...
