重构我的角度代码

Question

I have a code here, where I used in there different controller. I thought of shifting this code to a factory but unable to do so. I'll explain more clearly. Below is my code.

scope.countDown     = 4;
scope.runCounter = function() {
            scope.countDown -= 1;            
            if ( scope.countDown > 0) timeout(scope.runCounter, 1000);              
            else scope.loginUser(); //can be different function
        };

What it does is just a countdown timer. When the countdown hit to 0 it will call a scope function. As far as my re factoring go I have this:

my factory:

runCounter : function(countDown, callback) {
        rootScope.countDown = countDown;
        var self = this;

        rootScope.countDown -= 1;            
        if ( rootScope.countDown > 0) timeout(self.runCounter, 1000);              
        // else callback();
      }

I dont know how to pass a function inside my factory function. How can I achieve this?

Thanks,

I am not sure what you want to achieve, but this is a standard use case for $timeout service.

$timeout(myfunction,noOfSeconds * 1000);

in your case

$timeout(scope.loginUser,4 * 1000);

See documentation

Update You can do something like

runCounter : function(countDown, callback) {
    $timeout(callback,countDown* 1000);      
}
