Call UI Script from Catalog Client Scripts

[Joy715]

I need to run field auto-fill and validation for all catalog items.

So I made a common UI Script.

I try to call UI Script in Client Script but It shows this error message "(g_env) [SCRIPT:EXEC] Error while running Client Script "[Catalog Client Script Name]": ReferenceError: [UIScriptName] is not defined" in Service Portal.

Is there no way to call UI Script from Catalog Client Scripts for Service Portal?

UI Script :UIScriptName

var UIScriptName = Class.create();

UIScriptName.prototype = {
    ......
    validate: function(value) {
		var result= true;
		.....
		return result;
    },
    .....
};

 Catalog Client Script onChange

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }
    return new UIScriptName().validate(newValue);
}

Hi Joy,

In case you haven't yet found an answer, this post may help:

Apparently, this solution is specific to calls from Service Portal, and apparently won't work if the call is made from the Native UI, such as through the Record Producer "Try It". Still looking for a solution for the latter. 😕

Good luck!

Thank you for answering my forgotten question!

It seems like I resolved it in a similar way to the solution you provided.
