Periodically, I run into this problem and find out that I don't have
*.js files mapped to the JSP servlet in Tomcat. It may not be your
problem, but if you are running javascript that comes from a separate
file with a .js file extension, tags and scriptlets don't work unless
you have mapped them to the JSP servlet. 

I've had this problem when using tags in both JS and CSS files. It's
easy enough to fix, but it's a mistake I make with every project I start
from scratch and always takes me an hour or more to figure out :)

That's most likely not what you wanted, you mean:

<% String aString = "Hi There!"; %>

Hopefully that was typos.

Do you have scriptlets enabled?

> myFunc('msg')

Er, if *that* doesn't work, then you've done something horribly wrong, because 
that's just calling a JavaScript function with a literal string.

Hi Dave,

Thanks for replying.
Yeah I declared variables in my JSP file and tried to parse them through as
arguments to the JavaScript function like mentioned.
No matter how I tried to pass those values in as parameters, my JavaScript
function kept treating it as literal text hehe!

Like:

<%=String aString = "Hi There!"%>

onclick="return myFunc('<%=aString%>');"

myFunc would print out "<%=aString%>" rather than "Hi There!".

Also tried:

myFunc(<%=aString%>);

i.e. without the single quotes.

Also tried:

myFunc('msg')

etc etc.

Funny because I've done this in other JSPs.

Yes that underlying fact with client and server side resources.

Ah well ... Thanks again.
Nicole

Not really: you're trying to access server-side resources from the client side. 
If you're not going to run your JavaScript through the JSP processor your 
options are limited, for obvious reasons.

One solution was already given to you: deal with server-side resources in the 
JSP, use them as arguments to JavaScript functions contained in an external 
JavaScript file, by using custom tags, scriptlets, etc. to set parameter values.

You can also generate JavaScript on the server-side by means other than a JSP 
(FreeMarker, servlet, etc.), or generate JavaScript during the build process, 
or generate the JavaScript at application startup, or use something like DWR to 
access a Java object that loads resources at runtime, or... ad nauseum.

The underlying issue won't go away; there's client-side resources, and there's 
server-side resources. That's one of the many unfortunate natures of web 
applications, AFAICT.

Re: ApplicationResources.properties and JavaScript

Hi Owen,

Thanks for your reply.
I think I did try that.
The only solution I have found to work was to do this:

Application.properties:
my.message=Hi There!

myJSPFile.jsp:


myJSFile.js
var msg = document.myform.myMessage.value;
alert(msg);

The deadline is today so I'll have to do what works so far :(((

Thanks heaps to all for trying to help.
There must be a more elegant solution than this!

Cheers

Re: ApplicationResources.properties and JavaScript

[Owen Berry]

In your jsp code set a variable to be the value you want, as shown
earlier in this thread by Balwinder, and then read that variable in
your Javascript code. If you're using OO javascript, you can make it
nice and tidy by passing the parameter in your "constructor", or set
it in a method. Example:

var obj = new FancyObject('');
// -- or --
obj.setSomeValue('');

Make sense?

Thanks for that.
I think that only works if the javascript is within the JSP file right?
My javascript functions are in it's on .js file ...

I've found a way where I can just pass a value from the app resource file as
a parameter, but discovered that I return alerts with different messages
based on some criteria.

Any ideas?

Thanks heaps

  

Try this

var someVar = '';



hope this will serve the purpose.

ApplicationResources.properties and JavaScript

[nauke .]

Hi all,

Is there a way to access values in ApplicationResources.properties in
Javascript functions?
I've found a way where I can just pass a value from the app resource file as
a parameter, but discovered that I return alerts with different messages
based on some criteria.

Any ideas?

Thanks heaps
