Hi Everyone,

So glad that I found this forum dedicated to javascript solutions and expertise. I am hoping that someone can help me as I am still a beginner with using javascript. It really is some great stuff!

I have some drop down list boxes on a form and a check box. When the check box is clicked, it enables the list boxes so they can be selected, otherwise they are deselected. The script seem to be working just fine.

Then recently, I upgrade my browser to IE8 and began getting this error, though I cannot see what the issue is really. The file location (URI) exists as I pasted that into the browser and it wanted to download it, so I know the path is correct to the file.

Message: Invalid character
Line: 1
Char: 1
Code: 0

I opened the file, but cannot see any invalid characters with it. Here is the script:

 
function toggleInputs(daCheckbox,rowNumber){
var disabled = ! daCheckbox.checked
document.getElementById("LIST1_"+rowNumber).disabled = disabled
document.getElementById("LIST2_"+rowNumber).disabled = disabled
document.getElementById("LIST3_"+rowNumber).disabled = disabled
}

Note: For some reason when I paste the script here, the disabled comes out to be disabl ed (with a space) though I am not pasting it that way.


Thank you for any help or assistance with this.

Use the javascript debugger in Firefox or Seamonkey to get some meaningful error messages instead of the obtuse and misleading IE messages.

Okay, FireFox says the following:

Error: toggleInputs is not defined

This is how I am calling it:
<input type="checkbox" onclick="toggleInputs(this,1)>


This is how I have it defined in the HTML

<script type="text/javascript" src="C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\test\js\disable.js">
</script>

okay, I think I found the issue that wasn't syntax related.

What I did was remove referencing the external file and copied the script so that it was directly hardcoded. It worked like that.

It could be something with the apache server not able to see the file? But I need to keep the code stored in each .js file for security and maintenance easier.

because the apache server doesn't have a path of

C:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\test\js\disable.js

to the file THAT will only work on your machine.

So I assume instead of a direct path, that really it needs to be called through the HTTP:\\www.xxx.xxx\mypath\js\disable.js so the engine can serve it up to any client calling? I will try that to see what I get. The weird part is that previously I had no issues.

I did have to reload my development environment. Maybe it is possible that I specified a path in the configuration, but it should have carried over as I reloaded the same backup files.

I am able to reference the js file by accessing through the webserver by calling http://www.xxx.xxx/test/js/disable.js

The only problem is now, if I paste that into the address bar, it allows me to download the file. I don't want to necessarily want folks to be able to see inside of these files for more complex things later that give inside references about the system. How can I prevent that from being accessed?

Is there another method I need to choose in order to use js while meeting some sort of security requirement?

How can I prevent that from being accessed?

You can't. javascript is processed on the client machine so HAS to be downloaded.

just using a root relative path is sufficient

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

Do google search for encryption of html files.
There are lot of small programs free for use which will encode your JS files the way that code will basically look like a jebrish but parse normally.
