JavaScript in Creator-projects

Question

Hello,
I have a question about JavaScript. I have a page with two textfields, each 10 characters in length and below of each other.
What I would like to achieve is the following:
If a user enters one (or more) characters in one field, then the other field should be filled automatically with corresponding (but other) characters (it has to do with DNA-analysis).
For example, if a user enters a 'C' in one field, then the other field should be updated with a 'G' and the other way round.
Because the logic is quite simple, I think using JavaScript would be better than using AJAX. So does anybody know how to do this or where I can find some tutorial about JavaScript in Creator (I already searched the Creater-homepage and the blogs and couldn't find anything...)
Thank you!
Felix

Answer 1

Can you further explain "did not work"? What are your symptoms, error messages? Is the browser not seeing your JavaScript or is there an error in your JavaScript that prevents the browser from executing it.
Have you tried using your browser's debugger to determine where the problem is? Have you seeded the JavaScript with alert statements to find out what is working and what isn't?
Not knowing exactly where you are running into trouble, I can only give out a couple of solutions. They may or may not fit your situation.
o One way to insert JavaScript into a JSP file is to wrap it in
<script><![CDATA[ & ]]></script> start and end tags. This ensures that the script makes it to the browser intact.
o Here is one way to add a .js file and reference it from your page:
# Assuming that your .js file doesn'ty already exist in the web folder...From the main menu choose File > Add Existing Item > Other (All Files).
# Navigate to and select your .js file
# Click Add.
The IDE puts the file under he Source Packages > <project> folder. In the next step, you move the file to the web folder.
# In the Projects window, right-click the Source Packages > <project> > <your file>.js node and choose Cut from the pop-up menu.
# Right-click the Web Pages node and choose Paste from the pop-up menu.
# View your page in the Visual Designer.
# Drag the Script node from the Advanced section of the Palette window and drop it on a blank spot on the page.
# In the Properties window for the Script, click the url property's ellipsis (...) button, select your .js file and click OK.
The .js will now be included in the JSP file for the page.
