Creating variables in JavaScript, reusing inside RAD expressions

[hilton.sousa]

Hello, everybody

I'm actually creating an interface between SC6 and a third party workflow tool. The tool writes directly on EVENTINM1, and instead of populating the field evfields with positional data separated by "^", it writes XML text.

The first RAD expression to be evaluated (when a new record of this type arrives) takes the XML and calls a Javascript function that parses it.

For instance, the following XML

<xml>
<name>Hilton</name>
<email>hilton@com.com</name>
</xml>

is parsed into two Javascript statements, which are evaluated using eval() function:

system.vars.$xml.name="Hilton"
system.vars.$xml.email="hilton@com.com"

I've set some prints, and the attributions do occur without problems. But back in the RAD expressions, when I inspect the variables, both are empty :-(

How can I make the variables created within JS available to the RAD expressions ? Checking the "Service Center Programmer's Guide", it mentions assigning variables from within the Javascript of Format Control, and it does work - but doesn't meet my needs...

Best regards,
Hilton

I've got the answer after some more testing - in fact, I don't need to use system.vars. Just creating the variables as

$xml.name="Hilton"
$xml.email="hilton@com.com"

works fine !

So nevermind, and sorry for bothering you all :-D

Hello again

I've just discovered that I had manually created the $xml variables inside SC, and that's why it was working...

Now I had to reboot the server, and after this fresh start, the variables are not created anymore - so I'm back to the original problem: can't set variables within Javascript, and make them available to RAD expressions (event.register forms)...

Does somebody have any ideas on how to proceed ?

Regards,
Hilton

Initialise the variables outside javascript before calling the javascript.

Hello, tommy

I've tried your suggestion, setting the variables to "" before invoking my XML parser:

$xml.email=""
jscall(myFunction, evfields in $axces) // internally sets $xml.email to something read from the XML text

But it doesn't work - after the call returns (debug messages are printed from within javascript and correctly displayed in ev.msg), the variable $xml.email is still blank :-(

Try following

$xml.email=jscall(myFunction, evfields in $axces)

In your function end it with

return what-needs-to-be-returned

$xml.email=jscall(myFunction, evfields in $axces)

Sorry Tommy for correcting

$xml.email=jscall("myLib.myFunction",evfieds in $axces)

Well I just used the same notation and since Hilton says the javascript is executed (print statements) I assumed that the notation was just a simple pseudo code. But technically you are correct that is the syntax.
