问题 I have a Methode from an API. It returns a promise which resolves to an $ctrl(?) object. This objects should contain a measurement and will be updated whenever it receive a new data. getMeasurements.latest(filter) //only a object to filter through all measurements .then(function (latestMeasurement) { $ctrl.latestMeasurement = latestMeasurement; }); My problem is that I don't know how to work with this data or display it in my html file. How does $ctrl work? Here the documentation of the API

问题 I posted an issue on the AngularJS github but it doesn't seem to be getting a whole lot of attention and I wasn't able to fix it myself since it's a pretty low-level issue, so I think it's time to look for a workaround. Angular allows you to put a promise (or anything with a .then(...) function) into your scope, and once it is resolved, all $watches and anything bound to that promise will use the resolved value. The issue arises when you use a function to return a promise, as the same doesn't

问题 I have created a directive that accepts some attributes and initializes the isolated scope with these attributes. If an attribute isn't specified, then the isolated scope should be initialized with a calculated value. I added a link function that inspects the scope and initializes the default values (if no value has been set using the attributes). The scope has been initialized, but if I set a default value then it will be overwritten later by the framework. A workaround is to use $timeout(..

问题 I made a simple demo of a factory and I am trying to test this using jasmine . I am able to run the test but I am using the spyOn method.

问题 I am attempting to follow this [tutorial] but can't get it working. My Angular controller is logging undefined for a model created in my directive. Here is a [JSFiddle] of it working created my author of tutorial. The problem is the view can find $scope.myFile and but controller does not ( $scope.myFile is undefined ). The view displays {{ myFile.name }} (as just example my-image.jpg ). The myFile variable is a JS object containing data on selected file. This works fine. The directive seems

问题 I am new to angular Js. My application flow is as below: 1) I have a view controller wherein, each view controller sets the breadcrumb data with the help of Breadcrumbs factory. 2) Breadcrumbs factory takes data from view controller and attaches data to $location.$$state object.(reason for storing in state object is if back button is pressed, view controller doesn't instantiate so I can refer history data for breadcrumbs ) below is code to attach data to state object: var state = $location
