How to call a client-callable script-include function (accepting parameters) from server-side as well?

[Pranshu3]

Hi all,

I have a client-callable script include in my instance. A function within this script accepts client parameters [this.getParameter('sysparm_sys_id')].

Now to reduce code redundancy, I would like to call the same function from server-side (business rule).

How to make this client-callable script-include function accept parameters and get utilized from server-side as well?

Here is a whole solution:

//You call the client callable Script Include the same way as the server-side Script include

var scriptIncludeShortName = new ScriptIncludName();

//Then you call the Script Include function by dotwolking to his name

var valueReturnedBySIFunction = scriptIncludeShortName.theFunctionName(parameterOne, parameterTwo);

//Then you need to change the function declaration in the Script Include in a way that it can access values also from the server-side call

//That means:

//You need to change it from this:

functionName: function() {

     var firstParameter = this.getParameter("sysparm_parameter_one");

     var secondParameter = this.getParameter("sysparm_parameter_two");

     ...

}

// To this:

functionName: function(parameterOne, parameterTwo) {

     var firstParameter = parameterOne || this.getParameter("sysparm_parameter_one");

     var secondParameter = parameterTwo || this.getParameter("sysparm_parameter_two");

     ...

}

I hope that this will be helpful to someone.

For Scoped Applications, use the below

var abc = new global.ScriptIncludename();
var result = abc.ScriptIncludeFunctionName(current.yourparameter);

Please mark the answer as Correct and Helpful, if it works for you.

I believe @Earl Duque had a detailed blog post on this that he recently moved to Community somewhere. Look for that.
