Newsbar angular js fiddle4/6/2023 The stable release of AngularJS was on December 18, 2017, of version 1.6.8. Google released the initial version of AngularJS on October 20, 2010. Angular has features like generics, static-typing, and also some ES6 features. It is the successor of AngularJS and all mentions of Angular refer to versions 2 and up. var app = angular.module("demo", ) ĭocument.Angular is a TypeScript-based open source framework used to develop frontend web applications. Take a look at the test page for an example of how to do this. Note: You’ll have to stop the propagation of the event used to trigger the showing of the menus, because if you don’t, this document-wide click handler will immediately hide the menu after it’s shown. Angular JS has event emitters built into its scope objects, so we’re making use of those on the $rootScope variable, which is the overarching scope that is the eventual parent of all of the other scopes in your application. When the user hits escape or clicks anywhere on the document, the menus should hide. Here, we’re initializing the Angular JS application, and then hooking up some events that we can use to hide the menus once they’re revealed. And finally, we’ll take a look at the two directives used to render the menu: the menu itself, and the nested menu items. Second, we’ll take a look at the controller that initializes the directive. First, there’s the initialization of the Angular JS application. The JavaScript is broken down into a couple of different sections. For example, the sample usage above denotes three menu-items those three nodes would be placed inside the rendered HTML for the menu, as desecribed below. The ng-transclude directive is used to render child elements into the directive. I’m also setting the alignment class here, too, with left assigning the left class, and right the right, respectively. In this case, if visible is truthy (meaning not null or undefined), the show class will be added to the parent div. The only interesting thing going on here is the use of the ng-class directive, which indicates that a CSS class be added to the indicated element based on the truthiness of the specified variable. It’s relatively straightforward, but I’d still recommend you put this in a separate file for ease of use. Here’s the HTML for the directive template. Use the following to add the sliding menu directive to your page, where “visible” and “alignment” are variables on your controller. The CSS is a little complicated, as I’m adding fancy animations to do the actual sliding, but outside of that, it’s just plain old styling. The JavaScript is the meat of the article, and will explain how to create the sliding menu directive, as well as how to tie the Angular JS controller into the directive itself. The HTML shows how I’ve got the menu directive laid out, and also provides example usage. This article will be broken down into three separate sections: the HTML, the JavaScript, and the CSS. Visible indicates which controller variable should be responsible for showing the menu, and the alignment variable determines whether or not the menu slides in from the left side of the screen or the right side of the screen. The menu itself will be an Angular JS directive which takes just two arguments: visible and alignment. If you’re the kind of person who wants to see the big picture instead of having a step by step tutorial laid out for you, I’ve put together a demo page, which you can see here. The basic idea is that I want a menu to slide in from either the left or the right side of the screen based on some external controller action. I’d like to talk about how to create a sliding menu control using Angular JS and LESS CSS. Part 5 – Creating a Dropdown Control For Your Site.Part 4 – Creating a Focus Text Box Control With Fancy Feedback.This tutorial will teach you how to make a sliding menu using AngularJS directives among other tools. This intermediate AngularJS mini tutorial is part 3 of a 5 part series with each teaching you how to build something you can use on your web page.
