Add animation on dom event, by using a custom directive, the AngularJS $animate service and the Animate.css library.

Here’s is the code:

Yes, yes I know this can easily be done with the standard AngularJS ngAnimate directive, but I wanted to play around with a custom directive, isolated scope and the AngularJS $animate service. So I decided to use a wobble effect from the Animate.css library on a “alarm bell”.

 

The code use a css class “myWobble”, that uses a named keyframe animation from the Animate.css library, called: “wobble”.

.myWobble {
-moz-animation: wobble 1s;
-o-animation: wobble 1s;
-webkit-animation: wobble 1s;
animation: wobble 1s;
-webkit-animation-fill-mode: both;
-o-animation-fill-mode: both;
animation-fill-mode: both;
}

Then the custom directive “zvdz-animate” is used to start the animation on a dom event (in this case the on  “click” event). The directive will add the class “myWobble” to the element, when the animation is done and the “reset” option is set to “true”, the class “myWobble” will be removed, so when the user clicks again on the element, the animation is started again. When the “reset” option is set to “false” the class will not be removed and the animation will not be fired again.

In some case this is what you want, but in this case not.

<div class="alarmContainer" zvdz-animate="{ effects: [{ on: 'click', className: 'myWobble', reset: true }] }">
<a href="" class="fa fa-bell-o"></a>
</div>

How to sort items in a list with ng-repeat

Using ValidateAntiForgeryToken with AngularJS and MVC

I was getting a HTTP 500 error, when posting data from AngularJS to a MVC controller, which had the attribute ValidateAntiForgeryToken applied to it. This attribute expects a form to be posted to the MVC controller action method, but I wanted to sent JSON. If you want to do that then you can follow the blogpost from julian jelfs.

 

Now I just add: @Html.AntiForgeryToken()

Then I apply the custom attribute ValidateJsonAntiForgeryToken to the MVC controller action method, like

[HttpPost]
[Authorize] [ValidateJsonAntiForgeryToken]
public ActionResult GetDashboardData(DashboardViewModel model) {

Now I can Post data in AngularJS like:

// When using the @Html.AntiForgeryToken() and [ValidateJsonAntiForgeryToken], a http POST, 
// should contain a AntiForgeryToken in the header. // The @Html.AntiForgeryToken() will write add a hidden HTML input element with the name
//"__RequestVerificationToken". // This input element will contain to AntiForgeryToken. // The MVC AuthorizeAttribute [ValidateJsonAntiForgeryToken],
//will check the http request header for the "AntiForgeryToken".
function getHttpConfig() { var token = angular.element("input[name='__RequestVerificationToken']").val(); var config = { headers: { '__RequestVerificationToken': token } }; return config; }

var config = getHttpConfig();
var url = “http://localhost”;
var postData = {}; return $http.post(url, postData, config).then(function (response) {
// Do something terrible
});

Using AngularJS Batarang to debug AngularJS apps.

AngularJS Batarang is a Google Chrome plugin, that helps you identify problems in AngularJS apps.

 

For example in my last app, a Kendo UI chart was not showing correctly, so I opened the Google Chrome developer tools and switched to the AngularJS tab.

 

After selecting the correct scope, I could immediately see, I had made a mistake in my code.

Nice!

Microsoft Visual Studio 2013 Update 4 RC

Microsoft Visual Studio 2013 Update 4 RC can be downloaded at: http://www.microsoft.com/en-us/download/confirmation.aspx?id=44545

 

It contains many new features for an update: http://blogs.msdn.com/b/webdev/archive/2014/10/16/announcing-new-web-features-in-visual-studio-2013-update-4-rc.aspx

 

The thing I like the most:

 

Support for custom elements, polymer-elements and attributes

We no longer validate unknown attributers for custom elements as there will be many custom made tags in different frameworks. So there will no longer be squiggles under the unknown elements.
