Exception when calling script include from a different script include

[patrickfitz]

Hi,

encountering a sporadic error when trying to call a different script include.

var mySI = "MyOtherSciptInclude";

var k = new global[mySI]();

In my testing, the above code will work 90% of the time. When it does fail, my try/catch reports: undefined is not a function

Any insight/suggestions would be appreciated.

Hi, normally I would invoke a script include/function call with something like

var mySI = new MyOtherSciptInclude().myFunction();

// or

var mySI = new MyOtherSciptInclude();
var k =mySI.myFunction();

//Alternate for global scope

var mySI = new global.MyOtherSciptInclude().myFunction();

// or

var mySI = new global.MyOtherSciptInclude();
var k =mySI.myFunction();

Are you reffering to different scope when you say different script include? 

If yes, then the syntax would be something like this. 

var SI = new global.script_include();

SI.function_name();

For different scopes we use API name of script include instead of Script include name. 

Thanks,

Thanks for the quick responses 🙂

Both script includes are in 'Global' and the reason for my code formatting is that I have my code in a for loop and the value of 'mySI' is different for each iteration. ie

for( mySI in this.myObj) {

// if i write mySI to logs here, it is correct, but can fail on next line

gs.log(mySI); // correct value
var k = new global[mySI]();

k.someFunction(parm1...);

}

Thanks

Hi Patrick,

What is the type of value in this.myObj i.e. function, string, object?

you can check the type of this.myObj by using typeof() function. like this

gs.info(typeof(this.myObj));

To call ScriptInclude with dynamic name on each iteration the name should be of type function. If it is already of type function update the line as below.

//var k = new global[mySI]();

var k = new this.myObj[mySI]();

If the type of this.myObj is a string then you will need to first convert it to type function. eval() is used to convert string to function but please mind eval() is never recommended and has high-security concerns. 

var str = eval(this.myObj[mySI]);

Let me know how it goes. If you still face any issue do let me know the type of value in this.myObj so that I can further help you on this.

Thanks & Regards,
