javascript - AngularJS - How to display message "Loading..." while the content is being loaded? -

-

i found threads topic on so, looks way of loading data isn't best.

this how controller looks like:

app.controller("postsctrl", ['$scope', '$http', '$resource', 'posts', 'post', '$location', '$modal', '$timeout', function($scope, $http, $resource, posts, post, $location, $modal, $timeout) {       $scope.posts = posts.query();      ... add/edit/delete code

when page loaded, data db not displayed immediately. how display there loading... message?

i've tried using <div ng-if="loading">loading...</div> in view , 

$scope.loading = true; $scope.posts = posts.query(); $scope.loading = false;

in angularjs controller, doesn't seems working. i've noticed $scope.posts = posts.query(); executed every time when there's call controller.

is (or angularjs) way solve matter?

thank in advance.

what about

$scope.loading = true; $scope.posts = posts.query(function ()  {     $scope.loading = false; });

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
