View Full Version : Anylink Drop down menu Question

01-23-2007, 09:19 PM
1) Script Title:
AnyLink Drop Down Menu
2) Script URL (on DD):
3) Describe problem:
I can get it to work fine, and edit the links, color attributes, etc etc. But when I save the scipt to an external file, (in which I named menu.js, and placed in the root directory) and I make a reference in the head of the document to that script, it doesn't run. Is this script not capable of this? I'd hate to come back later and have to edit all 20 pages to update the menu. Or am I most likely just doing something wrong? Any thoughts?

You are doing something wrong. Here are my guidelines, look them over thoroughly:

Use a text editor to save the script, call it 'file_name.js' where 'file_name' can be any valid file name of your choosing. Substitute the name of your external .js file for some.js in the below:

<script src="some.js" type="text/javascript"></script>

Common problems arise when:

1 ) The script file is not in the directory specified. In the above example it must be in the same directory as the page(s) that use it. Below, it can be in the scripts directory off of the root of a domain:

<script src="http://www.somedomain.com/scripts/some.js" type="text/javascript"></script>

2 ) Opening, closing and/or 'hiding' tags are left in the external file. This means that you must strip:
</script>and any of their many variations from the beginning and end of the external file.

3 ) The external call (<script src="some.js" type="text/javascript"></script>) is not inserted into the page at the correct spot. The external call must be inserted at the same place on the page where the script was/would have been.

4 ) Paths to other files (if) used by the script are no longer valid due to its location. This is only a problem if the external script is kept in a different directory than the page it was working on when it was an internal script. To correct this, use absolute paths inside the script. Absolute path examples:



5 ) Inappropriately combining two or more scripts into one external file. Usually external scripts can be combined if one knows enough about scripting to do so properly. Even then it is possible to overlook something.

A rule of thumb when testing is, if it won't work on the page, it won't work as an external file either.

One other thing, if this is a DD script or any script that requires the credit remain for legal use, include the credit in the on page call, ex:

<script src="some.js" type="text/javascript">
* IFrame SSI script II- Dynamic Drive DHTML code library (http://www.dynamicdrive.com)
* Visit DynamicDrive.com for hundreds of original DHTML scripts
* This notice must stay intact for legal use

Make sure to retain all the 'decorations', as these include begin and end javascript comment delimiters without which the script won't function.

If you are still having problems, supply a link to your page.

I appreciate your reply, I've been through the suggested/common problems with no luck. Unfortunately, I can not supply a link as I'm testing locally. I'm thinking, and yes it's dangerous when I do that, lol, that in this script (AnyLink drop down menu) it calls to paste both .css and the java into the head of the document. Is it possible if I take ONLY the java script and create the named jave_script.js file, and add the reference to the head of my document instead of the actual script, that it would some how then make it invalid? Something to do with the .css now being a different place? I'm by far, no where near experienced with java, but i found this in the code.

if (ie4||ns6)
document.write('<div id="dropmenudiv" style="visibility:hidden;width:'+menuwidth+';background-color:'+menubgcolor+'" onMouseover="clearhidemenu()" onMouseout="dynamichide(event)"></div>')

Is the above orange a reference to the .css which would be pasted in the head of the document with this script? In which case, it's now seperate form one another. And would that cause this script to no longer function?

Thanks again in advance for any responses, and thanks jscheuer1 for your help thus far.
