Encountering an 'unresolved variable' error related to a variable utilized in the preceding line (PHPStorm 2018.2.5)

I'm facing a challenge in my IDE while working on a simple code. I'm currently using Angular 1.4 and ES 5.1.

function myFunction() {
    var vm = this;
    vm.listResults = null;

    SomeService.someFunction()
        .then(function (result) {
            vm.listResults = result;

            if (vm.listResults.length > 0) {
                vm.selectCity(vm.listResults[0]);
            }
        });
}

vm.selectCity = function (city) {};

The final if statement is causing a warning and indicates that the vm.listResults variable remains unresolved. The same issue arises with the call to selectCity and its parameter. I can't navigate to them by CTRL+CLICKing and it's unclear why.

What steps should I take to establish proper linking here?

Under

Languages & Frameworks > Javascript > Libraries
, I have selected angular-DefinitelyTyped, HTML, and Node.js Core, and nothing more.

While I could disable the warnings, I prefer not to. Understanding is key for me.

Thank you for your assistance :)

Answer №1

Essentially, my project functions as a large library that is frequently utilized by various other projects for common controllers, directives, services, filters, and more. AngularJS is not listed in its package.json because the library is imported into projects that already have it loaded. This may be why it was not functioning.

By incorporating this library into its own libraries, I was able to successfully resolve the issues I was experiencing :)
