AngularJS - how to override directive ngClick
Solution 1:
Every directive is a special service inside AngularJS, you can override or modify any service in AngularJS, including directive
For example remove built-in ngClick
angular.module('yourmodule',[]).config(function($provide){
$provide.decorator('ngClickDirective', ['$delegate', function($delegate) {
//$delegate is array of all ng-click directive
//in this case first one is angular buildin ng-click
//so we remove it.
$delegate.shift();
return $delegate;
}]);
});
angular support multiple directives to the same name so you can register you own ngClick
Directive
angular.module('yourmodule',[]).directive('ngClick',function (){
return {
restrict : 'A',
replace : false,
link : function(scope,el,attrs){
el.bind('click',function(e){
alert('do you feeling lucky');
});
}
}
});

I wrote a sample that removed angular built-in ng-click
and add a customized ngClick
Solution 2:
You can't override AngularJS built-in directives. However, you can define multiple directives with the same name and have them executed against the same element. By assigning appropriate priority
to your directive, you can then control whether your directive runs before or after a built-in directive.
This plunker shows how to build an ng-click
directive that executes before the built-in ng-click
does. The code is also shown below. When clicking the link, the custom ng-click
will run first, then the built-in ng-click
does.

return {
restrict: 'A',
priority: 100, // give it higher priority than built-in ng-click
link: function(scope, element, attr) {
element.bind('click', function() {
// do something with $rootScope here, as your question asks for that
alert('overridden');
})
}
}
})
.controller('MyCtrl', function($scope) {
$scope.alert = function() {
alert('built-in!')
}
})
