Correction: actually, it seems that there is an attempt
in the existing code to pass Javascript array to Java:
onsubmit="if(this.inclusions)excludes.value=getCheckedValues(inclusions,true);return
true;"
Interestingly, "inclusions" is a name of all checkboxes in XSL
page. But on Java side it doesn't use "inclusions", "excludes"
or "valueArray", but uses:
String [] exclusions = request.getParameterValues("exclusions");
- I don't see where request parameter "exclusions" is coming
from;
- later instead of that array exclusions[] they pass NULL to the
method which is supposed to create SQL based on that.
I checked a few Javascript books, and it looks like one has to
use LiveConnect technology to use JavaScript variables in Java,
that requires "import netscape.javascript.*" package.
There are no such imports in the code.
Are there other ways to use JavaScript vars in Java ?
What does "(this.inclusions)" means in
"if(this.inclusions)excludes.value=getCheckedValues(inclusions,true);return
true;" ?
Is that a sort of casting ? Passing array from JS to Java ?
Is that a legitimate way to pass variables JS->Java ?
Please advise.
Thank you in advance,
Oleg.
