Firing $watch event manually in angularjs

Question

I use this code:

$scope.$watch('message', function()
{
    // the code
});

Is there any way to fire change event of message manually, so the code will be executed?

Answer 1

Few options:

1. Use $scope.$apply() to run the digest loop which call all of the watch expressions

2. Put you inner watch code inside a function and call it manually

3. Change messages :)

Answer 2

Another option here is declaring the function separately and using $scope.watch with the pointer.

var watchFunction = function(){
    // the code
}

$scope.$watch('message',watchFunction);

watchFunction();
