When trying to set the context of a function and pass it as a callback, I am following this approach:
myController.myService.validateToken(param)
.then( myController.myService.getToken.bind( myController.myService ) );
myController.myService.getToken.bind( myController.myService )
However, I am unsure if this is the correct method?
Is there a similar functionality in Angular like bind()?
To find more information on the function angular.bind, you can refer to AngularJS 1.4.1 (Line 1146) where it is defined as follows:
function bind(self, fn) {
var curryArgs = arguments.length > 2 ? sliceArgs(arguments, 2) : [];
if (isFunction(fn) && !(fn instanceof RegExp)) {
return curryArgs.length
? function() {
return arguments.length
? fn.apply(self, concat(curryArgs, arguments, 0))
: fn.apply(self, curryArgs);
}
: function() {
return arguments.length
? fn.apply(self, arguments)
: fn.call(self);
};
} else {
// in IE, native methods are not functions so they cannot be bound (note: they don't need to be)
return fn;
}
}
When using this function, make sure to follow the syntax shown below:
var context, fn, args;
angular.bind(context, fn, args);
