variables in div tags?

[itsrick]

I am having trouble displaying a picture in a div tag in the body of my page. I think the problem lies in the fact that I need to use a variable to display the image and it is not carrying over for some reason.

The variables are all global and defined correctly in the functions. I hope this makes sense. If anyone can offer some advice, I will gladly try any thing. I can't even come up with any more search strings.

Here is the latest code I tried for inside the div tags...

<div id="jpgcontent">
<script language="Javascript">
document.write("<img name='jpg' src='jpg files/" + myList2[loopJPG] + "' width='811' height='607'>");
</script>
</div>

Thanks.

Global variables are defined outside functions. Though to be sure, show us the JavaScript code.

wow thanks for the quick reply. Sorry for the delay in posting - this is the first time I've been in front of a computer all day (that's both good and bad).

I don't have the code with me right now but I know that all of my variables are global because I am using them all in a few different functions where they keep the same value.

My current problem lies within this div tag though. I need to display a picture in a div (so i can show/hide it). I have written the code for this and it works. However, when I try use a variable (from the javascript functions in the html head) it will not display the picture.

This is a huge dillemma because I cannot display the picture without the variable.

I have tried so many different variations already it is hard to list them all. When I get back to my own computer I will put the code up but for now I would really appreciate it if anyone could offer some friendly advice. Thanks.

What errors do you get in the JavaScript console (Firefox)?

[itsrick]

no errors just a blank page when it is supposed to load the image.

No javascript variables in the body = div appears w/ image
With javascript variables in the body = blank page

I just tried a simple test. In the div I posted above, I wrote

document.write("hello"); which worked.

But when I put

document.write(myList2[0]); nothing happened.

myList2[0] is global because it is passed from one function to the other and I know it holds its value through the script.

What is going on here? Can you not carry javascript variables from the head to the body?

[Pepejeria]

Yes you can. I think I need to see some code to figure out whats wrong.

Thank you for trying to help. There is a hole in the wall shaped exactly like my head - it is no coincidence. I will post some code when I get back to the house in about an hour.

Also, in your original code you tried to iterate through an array with a string without quotes:

myList2[loopJPG]

should be

myList2['loopJPG']

But as pepejeria said, we'll need to see some code to fully understand the problem.
