Angular.js取消bind（）事件中的$ http请求

Question

According to this https://github.com/angular/angular.js/issues/1159

this should work, shouldn't it?

el.bind('keyup', function() {       
    var canceler = $q.defer();
    $http.post('/api', data, {timeout: canceler.promise}).success(success);
    canceler.resolve();
});

because it doesn't fire the request at all, no errors or anything, could it be because it's inside a bind function?

Answer 1

it indeed was because it's inside the nonangular bind() event, putting scope.$apply() after http and before resolve will fix it

el.bind('keyup', function() {       
    var canceler = $q.defer();
    $http.post('/api', data, {timeout: canceler.promise}).success(success);
    scope.$apply();
    canceler.resolve();
});
