The link function in AngularJS Directive is missing its context

While working on a custom AngularJS directive, I encountered an issue where I am unable to retrieve the $parse service from the directive function for Dependency Injection (DI):

It strikes me as odd because my code closely resembles the examples provided in the official documentation on custom directives at: https://docs.angularjs.org/guide/directive specifically under the chapter "Creating a Directive that Manipulates the DOM."

Could I possibly be making a mistake somewhere??...

Thank you.

Answer №1

The reason for this ReferenceError is because the variable $parse is defined in the parent scope (its parent function), but it is not being utilized within your link function. As a result, when you reach that point in the code, the variable has been optimized out and is no longer accessible for examination.

To resolve this issue, try assigning the $parse variable to a new variable inside the link function. This will allow you to inspect and use it as needed. Give it a try and see if that helps you move forward with your code.
