timeselector | A simple jquery plugin for time selection | Plugin library

I've recently started with typescript. I've created a dropdown using select and option tags in the template.

I'm new to Unit testing in Angular using Jasmine and Karma. I've written a spec file but I'm getting an error. Let me first show what I've done so far. I've created a custom component:

TimeselectorComponent

I'm new to Unit testing in Angular using Jasmine and Karma. I'm an intern. I was going through a spec file. I want to know what is meant by should create in this context. TimeselectorComponent is the component that I want to test. I took the code from my senior. The code is like this:

I have an array of time Slots, I want to highlight the start time and end time.

WHAT I NEED IS: On my first click, Selected div will get highlighted, AND on my second click, another selected div will get highlighted.

My code for div formation in which Time is written is:

I'm new to testing with Jasmine and Karma. Pardon me if I'm asking anything wrong. I've a component app-timeselector inside which there are some custom child components. The template looks like:

timeselector.component.html

This is my day 3 in Angular unit testing with Jasmine and Karma. I'm following Pluralsight lectures. First thing first, dls-option is a component which I'm using form a library. I'll explain. I'm using a library of angular components provided by our company. In the below code and are nothing but and tag of HTML. They've created color and font styling wrapper around it. Here's my code: timeselector.component.html Choose one from the list {{ mode }} timeselector.component.ts import { Component, OnInit, ... } from '@angular/core'; ... @Component({ selector: 'app-timeselector', templateUrl: './timeselector.component.html' }) export class TimeselectorComponent implements OnInit { modes = ["Novice", "Intermediate", "Expert", "Beast"]; ... } and here's my test file: timeselector.component.spec.ts import { TestBed, ComponentFixture } from "@angular/core/testing" import { TimeselectorComponent } from './timeselector.component' import { Component } from '@angular/core'; import { FormsModule } from '@angular/forms'; fdescribe('TimeselectorComponent', () => { let fixture: ComponentFixture; @Component({ selector: 'dls-label', template: '' }) class DlsLabelComponent {} @Component({ selector: 'dls-dropdown', template: '' }) class DlsDropdownComponent {} @Component({ selector: 'dls-option', template: '' }) class DlsDropdownOption {} beforeEach(()=>{ TestBed.configureTestingModule({ imports: [ FormsModule ], declarations: [ TimeselectorComponent, DlsLabelComponent, DlsDropdownComponent, DlsDropdownOption ] }); fixture = TestBed.createComponent(TimeselectorComponent); }) it('should create', ()=> { //expect(fixture.componentInstance).toBeTruthy(); }) }) But my test case is failing. Here's the screenshot: Please help me with this and also feel free to suggest other mistakes as well. This will help me in my career. PS: I just want to do a shallow testing. I want to mock child components.

I'm working on an Angular project. I need last day of a given month for a given year using moment. But there are some limitations. I don't have a full date in a proper mm-dd-yyyy, etc format. And also that data types are any. We'll have two input fields, one for the month and the other for year. Then on click of Get last day button I should get the last day in numeric format, because I've to perform some arithmetic on that later. See it's very simple:

timeselector.component.html

I'm new to Angular. I'm trying to access/mutate a variable of a parent component from the child component. I've drawn a small diagram to explain my structure.

1. Label 1: the parent component where the variable (to be mutated) is situated.
2. Label 2: the child component which will change parent's variable on click event.
3. Label 3: the button inside child which will trigger the change.

I have checked many solutions like:

1. Change parent component state from child component
2. Angular access parent variable from child component
3. Angular2: child component access parent class variable/function

But I'm not able to solve my problem. I've created an stackblitz also. Please have a look at my code.

timeselector.component.ts

I have a javascript script that's supposed to detect whenever an html form input with type="time" has any value entered.

However, whenever I enter a partial value (for instance, type one number, instead of a full time with AM/PM), it doesn't detect the input as having a value.

In the below example, timeSelector is the input with type="time".
