How to pass "current" dynamically within GlideEvaluator.evaluateString() as parameter..

[Shariq Azim]

Hello Everyone,

I am trying to run a script stored on a field/variable of a record(ritm)..Now I do not plan to create the "script"  type field on the form, thus ,cannot use GlideScopedEvaluator API (https://developer.servicenow.com/dev.do#!/reference/api/paris/server_legacy/GlideEvaluatorAPI#GlideEvaluator-evaluateScript_GR_S_O?navFilter=evaluatesc) .

I am able to manage with  GlideEvaluator.evaluateString() function , but unfortunately not able to use it properly.

For example, if the string field on the record has the value new script_include().function_name(current).  I am able  to call the correct function using

//example logic and code
var ritm = new GlideRecord('sc_req_item');
ritm.addQuery('sys_id', sys_id);// ihave this captured 
ritm.query();
 if (ritm.next()) {

var val="new script_include().function_name(current)";
var func_val;
var ct=func_str.indexOf("current");
if (ct >0){
	func_val= func_str.substring(0,ct)+
ritm+func_str.substring(ct+7) ;
}
	else{
func_val= func_str;
}

gs.print( GlideEvaluator.evaluateString(val) ); //new GlideScopedEvaluator().evaluateScript(gr, ' script_field_name',null))
// cannot be use as i dont have a script type field

}

the script include contains the code:

function: function_name(current){
  var reqstr_str;
  var ret_str = '';
  gs.log("script  starts  ="+current.number.toString() );
     
ret_str= current.number.toString() ;
        return ret_str;
}

So the intention is to get  fields like variables, number and etc.  The above code is  just an example not the complete logic.

Unfortunately, I am getting an error

Javascript compiler exception: missing ] after element list (<refname>; line 1) in:
new script_include().function_name([object GlideRecord])

I expect to get the answers as:

RITM0148336 // for example

But, obviously current is not passed into the script include as a gliderecord object but as   string if dont replace the current string within the parenthesis.

Any idea how to solve this?

Regards,

Shariq

var gr - some GlideRecord

var script - some code

var param = new Packages.java.util.HashMap();
param.put("current", gr);

GlideEvaluator.evaluateStringWithGlobals(script, param);
