"In TypeScript, when something is undefined, it means its value

I am currently working on a class with code to help manage a database.

export class DatabaseHelper {

    public browserID : number;
    private ConfigID = 17;
}

Within this class, I am attempting to access the value of ConfigID

SetBrowserID() {
        browser.getCapabilities().then(function (cap) {

            this.browserID = new commFnctions.appdata().getBrowserIDFromBrowserName(cap.get('browserName'));
        });
    }

However, I am encountering an error message:

TypeError: Cannot set property 'browserID' of undefined
typescriptprotractorangularjs-e2ee2e-testing

Answer №1

Understanding the basics of TypeScript involves utilizing arrow functions:

SetBrowserID() {
    browser.getCapabilities()
       //.then(function (cap) {
       .then((cap) => {

        this.browserID = new commFnctions
                .appdata()
                .getBrowserIDFromBrowserName(cap.get('browserName'));
    });
}
