JavaScript for Line of Business Applications

I’ve been struggling with understanding when and how to use jQuery inside an AngularJS directive and have the data binding work as expected.  I’ve got a good example I put together that shows how to do this as well as shows when you need to use the scope.$apply(). 

You can see from the below example that in the directive, I am using AngularJS.  Because our DOM is being modified outside of what AngularJS can see, it does not have a watch assigned to it and therefore in the AngularJS digest loop, the scope.cntjQuery does not get updated.  As we know, the $scope contains the “truth” of this application but if the digest loop is not run then the truth never makes it to the browser.  Calling scope.$apply() causes the digest loop to be run.

The main thing about AngularJS is that it allows us to extend the capabilities of HTML to serve the purpose of today's dynamic webpages. In this article I will show you how you can use AngularJS's Directives to make your development faster, easier and your code more maintainable. | Difficulty: Intermediate; Length: Medium; Tags: AngularJS, JavaScript

ngReactGrid is an Angular directive that can be used to render an enhanced HTML table or grid of data very fast using React as the rendering engine. It is based on ng-grid and jQuery DataTables. It uses HTML tables and supports fixed column headers by default.

AngularJS directives are what controls the rendering of the HTML inside an AngularJS application. Examples of directives are the interpolation directive ( {{ }} ), the ng-repeat directive and ng-if directive.
It is possible to implement your own directives too. This is what AngularJS refers to as "teaching HTML new tricks".

You can implement the following types of directives:
* Element directives
* Attribute directives
* CSS class directives
* Comment directives

Of these, AngularJS recommends that you try to use element and attribute directives, and leave the CSS class and comment directives (unless absolutely necessary).
The type of a directive determines how the directive is activated. An element directive is activated when AngularJS finds a matching HTML element in the HTML template. An attribute directive is activated when AngularJS finds a matching HTML element attribute. A CSS class directive is activated when AngularJS finds a matching CSS Class. And, a comment directive is activated when AngularJS finds a matching HTML comment.

I've created a custom directive shakeThat which has two scope variables. The first one submit calls the parent controller function submit() when the form is valid. The second one submitted is a Boolean value and false at the beginning. It simply defers the activation of error classes until the user clicks on the 'Login' button. Check out AngularJS Form Validation for more information about the submitted variable.

I get that ng-grid is based off SlickGrid and uses virtualization to not render the full data set, but I am not sure this works well with Angular and the performance issues you run into when you have 2000+ bindings on the page.

I knew I could not be happy with this project until I fixed this problem. I tried a lot things with ng-grid, using bindonce, and other suggestions but the performance gain would usually create a bug in one of the grids where I was expecting the bindings to work as usual.

At the time, I thought to myself that I should switch to ng-table. But I had written so much code already that the ng-table seemed too expensive.

That's when I decided to create a proof of concept with one of the bigger grids and render it with ReactJS.

I created an AngularJS directive called reactGrid, and tried to support ng-grid's api as much as possible (with some minor changes).

Built on top of D3.js and AngularJS, n3-charts.line-chart directive creates beautiful charts in AngularJS applications. It is simple and interactive.

* ng-flow

* RESTAngular

* ng-table

* ui-router

* ng-csv

Directives are the most important components of any AngularJS application. Although AngularJS ships with wide range of directives, you will often need to create application specific directives. This tutorial will give an overview of custom directives and explain how to use them in real world Angular projects. At the end of the tutorial, I will guide you through the creation of a simple note taking app with the help of Angular directives.

In my day job, I work on appear.in, a video chat service built with AngularJS and WebRTC. Recently, our application has become more complex, and our HTML templates ended up having a lot of state in them. We could no longer just use unit testing to verify our application logic, we also needed to test the state in our templates.

For our unit testing, we landed on using Jasmine and Karma, and this has worked fairly well for us. So when we wanted to test our templates, we wanted to use the same tools.
