HELP!
In a nutshell, I’m trying to create a dynamic text box in which text show up for one XML node but not for another, so I have some XML nodes that have info in them and others that don’t. This seems like it would be a realatively easy thing to do, but I’ve been working on figuring out how to do so for days with no avail.
I’m working on a template for my portfolio gallery at:
http://www.kristinemorical.com/new/test4.html
I’ve linked pdfs to just some of the images in my modified xml slideshow from the tutorial using the following code from this forum:
picture.onRelease = function() {
if (link[p] != null) {
getURL(link[p], "_blank");
}
};
Now, I’m trying to display the text “Click on image below to view PDF” in a dynamic text box when there is a pdf linked to the image and have the dynamic text box display nothing when there is no pdf linked. Right now it displays the word “undefined” when there is a empty XML node or there is now pdf linked, whihc is not desireable.
Any help would be greatly appreciated. I need to get this solved before I can go on to finish the rest of my site.
I’ve attached a link to my CS4 flash file and my code below:
