Reverse polarity of an angular.js filter

Question

Given a filter method that returns true if some condition is met, is it possible to invoke its opposite in HTML, e.g. to use:

\"item in items | filter:!AllDa         


        

Answer 1

shacker's answer didn't work for angular 1.0.7, so here's another way to do this:

// You can register this in your AppCtrl if you like, otherwise just use $scope.
$rootScope.not = function(func) {
    return function (item) { 
        return !func(item); 
    }
};

Then you would do this:

filter:not(myFilterMethod)
