In my project, I have a unique issue with a list item that toggles a modal and sets a parameter using ng-click. Strangely, when calling a specific function in another location, Course.SelectedCourse returns as undefined, even though Course.ID has a valid value.
<li class="facebook" style="width:33%;">
<a ng-click="Course.SelectedCourse = Course.ID" data-toggle="modal" data-target="#myModal">
<span class="glyphicon glyphicon-user"></span>
</a>
</li>
One way to handle this is by creating a function in the controller to set the selected course ID. Here is an example of how this could be implemented:
First, in the view :
<li class="facebook" style="width:33%;" >
<a ng-click="setSelectedCourse(Course.ID)" data-toggle="modal" data-target="#myModal">
<span class="glyphicon glyphicon-user"></span>
</a>
</li>
Then, in the controller :
function setSelectedCourse(course_id){
$scope.Course.SelectedCourse = course_id;
}
When using AngularJS, directives come with their own unique scope. If you are generating a list with ng-repeat, keep in mind that the scope inside this loop is different from the main controller's scope. This is why the line of code
"Course.SelectedCourse = Course.ID"
may not function as expected. However, the previous solution suggested in this scenario works because directives have the ability to call functions from the main controller.
