The functionality of ng-click and ng-repeat in AngularJS seems to be dysfunctional

I have knowledge about the different scopes within ng-repeat, I've heard about it but still can't figure out how to remove a selected item from the list without using $index and affecting future sortable objects.

<li class="m-1" ng-repeat="students in students.students">
  <span>{{students.student}}</span> :knowledge is - <span>{{students.knowledge}}</span>
  <button type="button" class="btn btn-danger ml-2" ng-click="students.removeItem(item)">Delete</button>
</li>

My function is working behind the li-element, but it only deletes the last element.

vm.removeItem = function (item) {
  vm.students.splice(vm.students.indexOf(item), 1);
}

I am trying to achieve this without the need for $parent in ng-repeat.

Answer №1

Perhaps you are attempting something along the lines of:

<li class="m-1" ng-repeat="student in students">
  <span>{{student.name}}</span> :knowledge is - <span>{{student.knowledge}} </span>
  <button type="button" class="btn btn-danger ml-2" ng-click="removeItem(student)">Delete</button>
</li>

$scope.removeItem = function (item) {
    this.students = this.students.filter(stud => stud !== item)
};

I find it confusing to have a nested object called students within students. Also, naming every item in ng-repeat as students seems unnecessary.

It appears more logical for each item to have the variable name of student.
