The documentation regarding $postLink() is correct. It’s called after its controller’s element and its children have been linked. This doesn’t mean that you’ll see a directive’s result immediately. Maybe it’s calling $http and inserting the result once it arrives. Maybe it’s registering a watcher which in turns sets the result, as most of Angular’s built-in … Read more
Updated 2015-01-17: As pointed out by Leblanc Meneses in the comments Angular 1.3 now supports interpolation with form, ngForm and input directives. This means that using expressions to name your elements: <div ng-form=”namesForm_{{$index}}” ng-repeat=”name in names”> <input type=”text” name=”input_{{$index}}_0″></input> <!– … –> </div> will work as expected: $scope[‘namesForm_0’] $scope.namesForm_1 // Access nested form elements: $scope.namesForm_1.input_1_0 … Read more
It is all about promises (actually every protractor question is about promises). browser.wait() is not a blocking call, it schedules a command to wait for a condition: Schedules a command to wait for a condition to hold, as defined by some user supplied function. If any errors occur while evaluating the wait, they will be … Read more
It enables AngularJS code to be minified. AngularJS uses parameter names to inject the values to your controller function. In JavaScript minification process, these parameters are renamed to shorter strings. By telling which parameters are injected to the function with a string array, AngularJS can still inject the right values when the parameters are renamed.
[EDIT] I wrote an article on my blog to explain things in more details: read it on sam-dev.net and you can now read part II, with code sample. I’ll answer my own question. Not because I think it’s the best approach, but just because it’s the one I’ve decided to go with. This is how … Read more
The HTML5 spec allows for arbitrary attributes as long as they’re prefixed with data- like so: <div data-myattribute=””></div> Whereas this would be invalid HTML5: <div myattrbute=””></div> For more information on data- attributes, have a look here. As for “x-” attributes, I think you mean “x:” attributes and elements, which are specific to XHTML validation… To … Read more
Your function is run 10 times. Why 10? Why not 100? The answer is in the docs: The watch listener may change the model, which may trigger other listeners to fire. This is achieved by rerunning the watchers until no changes are detected. The rerun iteration limit is 10 to prevent an infinite loop deadlock. … Read more
Since routes are defined on a provider level, normally new routes can only be defined in the configuration block. The trouble is that in the configuration block all the vital services are still undefined (most notably $http). So, on the surface it looks like w can’t define routes dynamically. Now, it turns out that in … Read more
ObjectID is not a global variable, it is defined by mongoose (see the documentation): var fileId = mongoose.Types.ObjectId();
Returning only a function in a directive is just a shorthand for the link function in the full definition. If you are specifying something other than a link function (like templateUrl) then you need to write it the long way: angular.module(“app”). directive(“widgetUno”, [“$http”, function ($http) { return { link: function(scope, element, attrs) { // A … Read more
