What is the process for removing a directive in AngularJS?

I have implemented a directive to manage the logic for an entity, such as a person.

My people service contains an array of individuals:

this.people = ["Person 1", "Person 2", "etc"];

The controller injects this service and sends data to a template that includes my directive. This results in a template structure like:

<div ng-repeat="person in people">
    <person name="person"></person>
</div>

Within my directive, I have a delete function triggered by a button click. The code for deleting a person looks something like this (where the People service is also injected into the directive):

delete People.people[id];

The challenge arises when trying to completely remove the directive upon deletion. Despite attempting to hide it using ng-hide or setting a 'deleted' property in the scope to true after deletion, I find that the empty directive template persists. I have explored methods like scope.$destroy(), element.remove(), but none have provided a clear solution as per the documentation...

What is the best approach to fully destroy/remove a directive from within itself when a delete function is called?

Fiddle: http://jsfiddle.net/VSph2/107/

Although clicking delete successfully removes the data, the directive and its template remain visible with just 'name:'. How can I ensure complete removal of the directive upon deletion?

Answer №1

When you delete an object, the empty element in the array remains as a null reference instead of pointing to another object.

To properly remove it from the array and prevent it from rendering in a for loop, use:

this.peopleIds.splice(this.peopleIds.indexOf(personId), 1);
