start angular function without click?

Question

I have a function in angular:

$scope.getSessionsForSpeaker = function (id) {
    $scope.id = id;
    $scope.getAll = SessionService.getAll();
    $scope.sessionsFound = [];
    $scope.getAll.$promise.then(function(data) {
        for (var i = 0; i < data.length; i++) {
            if ([data[i].speakers[0]] == $scope.id) {
                console.log([data[i].subject]);
                $scope.sessionsFound += [[data[i].subject] + ", "];
            }
        }
    });
};

and from html i run it by clicking a link:

<a ng-click="getSessionsForSpeaker(speaker.id)"></a>

Is there a way to run this function without clicking? Thank you in advance!!

Just call it - after declaration add $scope.getSessionsForSpeaker() — Oleksandr T.

You can do plenty. Do you want to call it on some event or from your code? You want it to run on when controller/link function runs etc.? — Chris Hermut

Chris, I want it to run when my page loads, or when I access a certain controller. — Deniss M.

You can run it from your controller if you know the ID:

$scope.getSessionsForSpeaker(id);

You can use ng-init to run it when that element loads:

<a ng-init="getSessionsForSpeaker(speaker.id)"></a>

You can also use ng-mouseover if you want to run it when the mouse is over that element

<a ng-mouseover="getSessionsForSpeaker(speaker.id)"></a>

All depends when you want to run it.

What's the point in creating a $scope method if a given function will only run in constructor function and will not get exposed as view model property?

He can run it from anywhere he likes, I have no idea how he wants to run it, so I've presented him with every choice I could think of.

<a ng-init="getSessionsForSpeaker(speaker.id)"></a> doesn't seem to work.

I found a solution that worked for me:

<p ng-bind-html="sessionsFound"></p>

Thanks to everyone for contribution!
