Hi, I'm working on a project that requires calling a perl function from the HTML code.
After searching online i found a tool called "Sajax" which can actually do this. http://www.modernmethod.com/sajax/
I made a simple application using this tool and it worked. I'm trying to use this tool in my form but its giving me weird errors.Presently i'm putting this tool to just print a string.
Actually i'm calling the javascript function add() on the onChange()event of a drop downbox which calls the perl wrapper function x_populate() to print a string.
I get the following error:-
Error: uncaught exception: [Exception... "Not enough arguments nsIDOMHTMLSelectElement.add" nsresult: "0x80570001 (NS_ERROR_XPC_NOT_ENOUGH_ARGS)" location: "JS frame :: unknown filename> :: onchange :: line 0" data: no]
The strange part is if i call the add() function on the onClick() event of a button it actually works. I dont know whats the issue with the onChange() event.
I guess this is a javascript error but how to resolve it.
Sample Code: 
function add(F){ 
x_populate(print1);
}

function print1(N1) {
    document.write(N1);
    document.write('Its Me');
} 

my $msub = sub {
    return 'Hey';
};

Sajax::rs_init();
Sajax::rs_register("populate",$msub);
//followed by some other Sajax functions


//calling add() function
<SELECT NAME="selectCourseDept" onChange="add(); return false;">
