If using Ui-Router with AngularJS and TypeScript, can I access the properties defined in a parent state from the nested estate directly (without using params or data)? I can use $state.$current.parent to access data in the data property, but I would like to access a property defined in the controller directly. I have called it xxx in the sample code provided. Here is my example: THE ROUTES: $stateProvider .state(STATE_NAMES.JOB_ADD.MAIN, { url: ‘/jobs/:Id’, redirectTo: STATE_NAMES.JOBL_ADD.DETAILS, views: […]

AngularJS Directive with Controller Constructor Never Fires
Hi I am trying to write a angularJS directive with a controller in typescript but I can’t seem to get my constructor to fire inside the controller.

Any insight into this issue would be greatly appreciated. class AdvancedFindDirective implements ng.IDirective { public […]
Create function event scroll swipe Typescript
I have the following piece of code that manages when scrolling with the keys up and down the keyboard: KeyEvents() { if (this.subskey != undefined) this.subskey.unsubscribe(); this.subskey = this.APPService.keyEvent$.subscribe((event) => { switch (event.keyCode) { case this.keyCodes.KEY_UP: this.isText(‘UP’); break; case this.keyCodes.KEY_DOWN: this.isText(‘DOWN’); break; } }); } Then with the isText(direction) function and a switch I can do the actions I want as I move down or up. For example when I move down I put an […]

How to transition an angularJS application to angular
I currently have a simple search functionality defined in AngularJS (https://next.plnkr.co/edit/qpyvZuvI8vw8q6on?open=lib%2Fscript.js&preview) but I’m hoping to migrate this feature into an existing Angular application. I created a new Angular application and moved the view into app.component.html <head> <script src=”./script.js”></script> </head> <h1> Search Feature </h1> <body ng-app=”search” ng-cloak> <div id=”content” ng-controller=”MainCtrl”> <input type=’text’ ng-model=’searchText’ placeholder=” Enter Query Here ” /> <ul> <li class=”angular-with-newlines” ng-repeat=”course in courses | filter:searchText”> {{course.course_number}}: {{course.title}} <button ng-click=”course.showDesc=!course.showDesc”>See More</button> <div ng-if=”course.showDesc”> Description: {{course.description}} […]
Set type to any from a list of classes
I have large list of components and a function that returns a component from that list based on a search query. The search function looks something like this: export const components = [Comp1, Comp2, Comp3]; export type AnyComponent = Comp1 | Comp2 | Comp3… ; export function findComponent(id: string): Type<AnyComponent>|undefined { return components.find(component => component.id === id); } Is there a way to avoid listing out my components twice both for the type definition and […]
