iam trying to use the autocomplete component
data is loaded (i can see it on the HTML)
but when user types inside the textbox
nothing happens
any idea why ?
thank u
the HTML:
<kendo-autocomplete [data]="data"
[placeholder]="'e.g. Denmark'"
class="countries" >
</kendo-autocomplete>
the TS:
import { Component, OnInit, NgModule } from '#angular/core';
#Component({
selector: 'app-product-search-box',
templateUrl: './product-search-box.component.html',
styleUrls: ['./product-search-box.component.css']
})
export class ProductSearchBoxComponent implements OnInit {
public data: Array<string> = ["Albania", "Andorra", "Armenia", "Austria", "Azerbaijan"];
constructor() {
}
ngOnInit() {
}
}
proof that data is loaded:
Make sure you have imported the BrowserAnimationsModule required for the popup animations:
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { BrowserAnimationsModule } from '#angular/platformbrowser/animations';
import { HttpModule } from '#angular/http';
import { DropDownsModule } from '#progress/kendo-angular-dropdowns';
import 'hammerjs';
import { AppComponent } from './app.component';
#NgModule({
imports: [ BrowserModule, BrowserAnimationsModule, HttpModule,
DropDownsModule ],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule { }
Everything in the provided code seems fine otherwise. You should also check for console errors like already suggested.
Here is an working example:

After upgrading to the latest cli and nativescript-angular I get a blank white screen when I start the app which opens the page tab based, but when I try to output something using the component ts file I can get it on the console. The problem is only at the template level (I get a blank page).

I have an js file which includes an array! The js file is like this one
export const appointments = [
{
"taskID": 9018929,
"resource_ID": 1,
"title": "KNDL Thatcham",
"description": "<Non-Selected>\r\n10:00 - 18:00",
"startTime": "2018-12-28T00:00:00",
"endTime": "2018-12-28T23:59:00",
"statusColour": "#DFDFDF",
"clientColour": "#FFFDD7"
}]
I have imported this js files in service.ts. And this appointments.js does not show in the console.log.
import { Injectable } from '#angular/core';
import { appointments } from '../appointments';
import { Color } from "tns-core-modules/color";
// >> angular-calendar-require
import { CalendarEvent } from 'nativescript-ui-calendar';
#Injectable({
providedIn: 'root'
})
export class CalendarService {
constructor() {
//var a="test test etsdhsakdsakd dsddssdsd";
console.log(appointments);
}
This is the component where I am importing the service.ts
import { Component, OnInit } from '#angular/core';
import { CalendarService } from "./service/calendar.service";
import { RadCalendar, CalendarEvent, CalendarSelectionEventData } from "nativescript-ui-calendar";
#Component({
selector: 'ns-calendar',
templateUrl: './calendar.component.html',
styleUrls: ['./calendar.component.css'],
moduleId: module.id,
providers: [CalendarService]
})
export class CalendarComponent implements OnInit {
}
You need to add a private calendarService parameter of type CalendarService to the constructor.
When Angular creates a CalendarComponent , the Dependency Injection system sets the calendarService parameter to the singleton instance of CalendarService .
export class CalendarComponent implements OnInit {
constructor(calendarService : CalendarService ) {}
}
I am developing an Angular web application using:
Angular 4.1.2
Angular Material 2.0.0-beta.11
I am trying to create a simple modal dialog and on reading the Angular guide documents (Dialog | Angular Material) I see that there are several directives available to make it easier to structure the dialog content.
I cannot work out how to implement md-dialog-title, <md-dialog-content>, <md-dialog-actions> or md-dialog-close. The attributes, when applied to an element, appear to make no difference at all and the <md-dialog-content> and <md-dialog-actions> create errors like this:
Unhandled Promise rejection: Template parse errors: 'md-dialog-content' is not a known element:
Any guidance would be very welcome please. Here are some further details of my project:
For my initial development I have created an Angular module, named AngularMaterialModule to manage my Angular Materials. Here is a summary of it:
import { NgModule } from '#angular/core';
import {
MdAutocompleteModule,
MdButtonModule,
....
MdStepperModule,
StyleModule,
} from '#angular/material';
import { CdkTableModule } from '#angular/cdk/table';
import { A11yModule } from '#angular/cdk/a11y';
import { BidiModule } from '#angular/cdk/bidi';
import { OverlayModule } from '#angular/cdk/overlay';
import { PlatformModule } from '#angular/cdk/platform';
import { ObserversModule } from '#angular/cdk/observers';
import { PortalModule } from '#angular/cdk/portal';
#NgModule({
exports: [
// Material Modules
MdAutocompleteModule,
MdButtonModule,
....
PlatformModule,
PortalModule
],
declarations: []
})
export class AngularMaterialModule { }
My Visual Studio Solution was created using dotnet new angular taking advantage of the Microsoft ASP.Net SPA Templates.
In my app.module.client.ts file I import the AngularMaterialModule, described above, like this:
import { NgModule } from '#angular/core';
import { BrowserModule } from '#angular/platform-browser';
import { BrowserAnimationsModule } from '#angular/platform-browser/animations';
import { FormsModule } from '#angular/forms';
import { HttpModule } from '#angular/http';
import { AngularMaterialModule } from './core/angular-material.module';
import { sharedConfig } from './app.module.shared';
#NgModule({
bootstrap: sharedConfig.bootstrap,
declarations: sharedConfig.declarations,
imports: [
BrowserModule,
BrowserAnimationsModule,
AngularMaterialModule,
FormsModule,
HttpModule,
...sharedConfig.imports
],
providers: [
{ provide: 'ORIGIN_URL', useValue: location.origin }
]
})
export class AppModule {
}
You need to import the actual dialog module into the module you want to use it in.
import { MdDialogModule } from '#angular/material';
#NgModule({
imports: [
MdDialogModule
],
})
After that, it's a straight forward and follow the example in their docs
import {Component, Inject} from '#angular/core';
import {MdDialog, MdDialogRef, MD_DIALOG_DATA} from '#angular/material';
/**
* #title Dialog Overview
*/
#Component({
selector: 'dialog-overview-example',
templateUrl: 'dialog-overview-example.html'
})
export class DialogOverviewExample {
animal: string;
name: string;
constructor(public dialog: MdDialog) {}
openDialog(): void {
let dialogRef = this.dialog.open(DialogOverviewExampleDialog, {
width: '250px',
data: { name: this.name, animal: this.animal }
});
dialogRef.afterClosed().subscribe(result => {
console.log('The dialog was closed');
this.animal = result;
});
}
}
#Component({
selector: 'dialog-overview-example-dialog',
templateUrl: 'dialog-overview-example-dialog.html',
})
export class DialogOverviewExampleDialog {
constructor(
public dialogRef: MdDialogRef<DialogOverviewExampleDialog>,
#Inject(MD_DIALOG_DATA) public data: any) { }
onNoClick(): void {
this.dialogRef.close();
}
}
If you ever want to create a custom dialog component, you will have to add it into your entryComponents in the module.
import { MdDialogModule } from '#angular/material';
#NgModule({
entryComponents: [
AddressDialogComponent,
],
imports: [
MdDialogModule,
],
exports: [
AddressDialogComponent,
],
})
I am having a app.component.html file with button to navigate to another component called HomeComponent
<button (click)="nav()" id="nav">Navigate</button>
<router-outlet></router-outlet>
My app.component.ts file
import { Component } from '#angular/core';
import { RouterModule,Router, Routes } from '#angular/router';
#Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'app';
constructor(private router: Router){
}
nav(){
this.router.navigate(['/home']);
}
}
and my app.module.ts
import { BrowserModule } from '#angular/platform-browser';
import { NgModule } from '#angular/core';
import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';
import { RouterModule, Routes,Router } from '#angular/router';
#NgModule({
declarations: [
AppComponent,
HomeComponent
],
imports: [
BrowserModule,
RouterModule.forRoot([{ path: "", component: AppComponent}]),
RouterModule.forChild([{ path: "home", component: HomeComponent}])
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Here is my spec file app.component.spec.ts
import { TestBed, async, ComponentFixture, fakeAsync, tick,inject } from '#angular/core/testing';
import { By, BrowserModule } from '#angular/platform-browser';
import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';
import { DebugElement } from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
import { Router, RouterOutlet } from "#angular/router";
import { FormsModule } from "#angular/forms";
import { RouterTestingModule } from '#angular/router/testing';
import * as br from '#angular/platform-browser';
describe('Component:AppComponent', () => {
let location, router;
let mockRouter
beforeEach(() => {
mockRouter = {
navigate: jasmine.createSpy('navigate')
};
TestBed.configureTestingModule({
imports: [RouterTestingModule.withRoutes([
{ path: 'home', component: HomeComponent }
])],
declarations: [AppComponent, HomeComponent]
});
});
it('should go home', async(() => {
let fixture = TestBed.createComponent(AppComponent);
fixture.detectChanges();
console.log(mockRouter.navigate);
let component = TestBed.createComponent(AppComponent).componentInstance;
component.nav();
spyOn(component, 'nav');
fixture.detectChanges();
expect(mockRouter.navigate).toHaveBeenCalledWith(['/home']);
}));
});
I am getting the result as
In order to create unit test case for router.navigate you can do something like this:
import { TestBed, async, ComponentFixture, fakeAsync, tick,inject } from '#angular/core/testing';
import { By, BrowserModule } from '#angular/platform-browser';
import { AppComponent } from './app.component';
import { HomeComponent } from './home/home.component';
import { DebugElement } from '#angular/core';
import { RouterModule, Routes } from '#angular/router';
import { Router, RouterOutlet } from "#angular/router";
import { FormsModule } from "#angular/forms";
import { RouterTestingModule } from '#angular/router/testing';
import * as br from '#angular/platform-browser';
describe('Component:AppComponent', () => {
beforeEach(() => {
TestBed.configureTestingModule({
imports: [RouterTestingModule],
declarations: [AppComponent, HomeComponent]
});
});
it('should go home', async(inject([Router], (router) => {
spyOn(router, 'navigate'); //added a spy on router
let fixture = TestBed.createComponent(AppComponent);
let component = TestBed.createComponent(AppComponent).componentInstance;
component.nav();
expect(router.navigate).toHaveBeenCalled();
expect(router.navigate).toHaveBeenCalledWith(['/home']);
}));
});
You have spied on router but you haven't provided it to the testBed environment. Try adding
providers: [
{ provide: Router, useValue: mockRouter},
],
after declarations.
Also you need not include RouterTestingModule since you are not clicking any links.

Angular 2 Unit Testing - Cannot read property 'root' of undefined
I'm trying to use the isBrowser function in angular universal but I keep getting the same error when I build. I did install the npm package of angular-universal
npm i angular2-universal --save
'ng build -prod -aot'
ERROR in Illegal state: symbol without members expected, but got {"filePath":"C:/dir/universal/website/node_modules/#angular/platform-browser/platform-browser.d.ts","name":"__platform_browser_private__","members":["BROWSER_SANITIZATION_PROVIDERS"]}.

It looks like they are using isPlatformBrowser() instead of isBrowser() in the angular universal example.
