In our application module controller (graphPlotterDemoCtrl), we used the $scope object and attached the graphPlots variable (which contains the data for the 4 plots) to it.Here, the scope object is nothing else but the $scope object we attached our graphPlots variable inside the controller of our application module. Once the directive is applied to a component. We have applied this directive to 2 elements h1 and div. In this directive, we are going to highlight the selected DOM.
So, let's get started with creating our first Custom Attribute directive. To create a custom directive we have to replace Component decorator with Directive decorator. This is how we can create the directive by providing the directive name, for example. Creating a custom directive is just like creating an Angular component.
They have custom client software for Windows and Mac OS X, and various Linux. The command we need to execute is given below. on this occasion I will convey about AirVPN 2018 Premium VPN Review Review. The custom directive updates the backgroundColor property of the elements on which it is applied. To create the custom directive, we can use Angular CLI. In the above code, we have created a custom attribute directive appl圜olor. As they have stated, link option will be a function which takes scope, element and attrs as parameters. We will name this custom attribute appl圜olor. We will sort it our soon! Since we are going to modify the DOM, it is obvious that we need to use the link option. ntroller( 'graphPlotterDemoCtrl', [ '$scope', function ($scope) where:Įlement is the jqLite-wrapped element that this directive matches.Īttrs is a hash object with key-value pairs of normalized attribute names and their corresponding attribute values.ĭon't worry it does not mean anything for you. Because every angular module should have a name! So what else is better than a beautiful name like 'graphPlotterDemoApp'.
(Because all we are going to do in this application is demonstrating our directive :P)Īs I mentioned earlier, we are writing the application module inside the app.js file. For the sake of simplicity we will make our application a Line Graphs - Demo Application. This can be a sales system, banking application, dashboard of a blog, POS system etc. Now we are going to implement our application. Step 3 - Implementing our application module Those are the expected outcomes of an AngularJS Directive. By separating the data and the logic of displaying like this, we preserve the re-usability and extensibility.
If you feel like you know what you are doing before I explain it, feel free to fast-forward)Īctually what we are going to do is, define and manipulate the data required to plot the graph inside our application module (app.js) and use the custom attribute to display them in a line graph. (These explanations will waste the valuable time of experienced programmers. Therefore graph-plotter.js should be imported before app.js. We know that our application module (app.js) makes use of our custom directive.
We have imported the angularjs after that. Since all the 3 Plotly libraries require jquery, it should be loaded before everything. Plotly Graph Plotter Directive for AngularJS - Demo Note on the order of importing javascript files (Skip if you understand)
