问题
I have a webpage written in angular with an ngCloak directive. It is loaded in a dynamically sized iframe with pym.js.
The trouble is that the page does not appear unless I resize the browser or trigger a resize event, or call pymChild.sendHeight() after the page loads.
I don't see any events associated with ngCloak though. Is there an angular event for "page is rendered, controllers are initialized"?
回答1:
There is the $timeout service:
$timeout(function() {
// this code will execute after the render phase
});

You could write a directive that execute a callback in postLink function, since the postLink will be called last in the $compile life cycle.
.directive('onInitialized', function ($parse) {
return {
restrict: 'A',
priority: 1000, // to ensure that the postLink run last.
link: function postLink(scope, element, attrs) {
$parse(attrs.onInitialized)(scope);
}
}
});
and place it at the element that you would like to know when it and all its template-ready decendants have got compiled, for example:
<body ng-controller="MainCtrl" on-initialized="hello()">
and in the MainCtrl controller:
app.controller('MainCtrl', function($scope) {
$scope.name = 'World';
$scope.hello = function () {
console.log('Hello ' + $scope.name);
};
})
For template-ready, I mean all directives except: directives with templateUrl and the template haven't ready in the $templateCache yet, since they will get compiled asynchronously.
Hope this helps.
