How do I render a URL which is not encoded. Below is a sample
import { Component } from '#angular/core';
import { Router } from '#angular/router';
#Component({
selector: 'demo-app',
template: `<a [routerLink]="stringURL">Click here</a>`,
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
stringURL:string;
constructor(){
this.stringURL = "/url;mode=3"
}
}
The URL in the template has encoded string like /url%3Bmode%3D3 and I want it like /url;mode=3
How can I achieve this.
Here's the sample : https://stackblitz.com/edit/angular-q6mf3p
Thanks
You have to disable angular default URL encoding.
This post explains the solution quite well.
If the link is static, you can use the directive as follows: link to user component
If you use dynamic values to generate the link, you can pass an array of path segments, followed by the params for each segment.
For instance ['/url',{mode: 3}] means that we want to generate a link to /url;mode=3.
you code will work see this new link click to see
import { Component } from '#angular/core';
import { Router } from '#angular/router';
#Component({
selector: 'demo-app',
template: `<a [routerLink]="stringURL">Click here</a>`,
styleUrls: [ './app.component.css' ]
})
export class AppComponent {
stringURL:any;
constructor(){
this.stringURL = ["/url",{mode:3}]
}
}
today i have a div which name is "title" ,
I have the task of making it move, so now I can do it in javascript with 'dragable', but I am using angular 5 and my posture is as follows :
import { Component, OnInit, Input } from '#angular/core';
import{ AppComponent } from '../app.component'
#Component({
selector: 'app-modal',
templateUrl: './modal.component.html',
styleUrls: ['./modal.component.css']
})
export class ModalComponent implements OnInit {
constructor() { }
ngOnInit() {
}
}
you can see my html and css in code pen https://codepen.io/__knif147/pen/yKjmao
So, i have to give it move when i hold the 'title ' div, somebody else help me please.

go through this link.demo for drag and drop.
you have to install npm for that and put reference in app.module.ts in your project (npm install ng2-dnd --save) provided by angular
I'm using Vue Onsen UI and trying to render a Vue single file component for each tab.
In the documentation here, they make use of template in a single page. Which is not very reusable. I want to be able to import custom component and render that.
Here is something that I'm trying to do which doesn't seem to work.
<template lang="html">
<v-ons-page>
<!-- top tab bar -->
<v-ons-tabbar position="top" :index="0">
<v-ons-tab label="Browse" page="TaskList">
</v-ons-tab>
<v-ons-tab label="Second">
</v-ons-tab>
</v-ons-tabbar>
</v-ons-page>
</template>
<script>
import TaskList from './TaskList';
export default {
template: '#main',
components: {
'task-list': TaskList,
},
};
</script>
<style lang="scss">
</style>
Can you suggest anything that I should try?
Instead of using tab objects that reference the components directly, use the :tabs property of the tabbar to set up the pages:
<template lang="html">
<v-ons-page>
<v-ons-tabbar position="top" :index="0" :tabs="tabs">
</v-ons-tabbar>
</v-ons-page>
</template>
<script>
import TaskList from './TaskList';
import SecondPage from './SecondPage';
export default {
template: '#main',
data: function () {
return {
tabs: [
{label: 'Browse', page: TaskList},
{label: 'Second', page: SecondPage}
]
}
}
};
</script>
Also, make sure the root element of the components you reference in the page property are <v-ons-page> elements.
I was having the same difficulty with the following syptoms:
Tabs were not appearing at all
No errors in CLI or in console
Note that I was also using the "Hello World" app that is generated from the CLI (vue init OnsenUI/vue-pwa-webpack hello-world)
Resolution
It was pretty simple in the end: there is a file in the root of the folder called vue-onsen-components.js which has all of the components and some of them are commented out. I had to uncomment the following lines and then the tabs appeared:
export { default as VOnsTab } from 'vue-onsenui/esm/components/VOnsTab'
export { default as VOnsTabbar } from 'vue-onsenui/esm/components/VOnsTabbar'
I am trying to apply the html from my internal text/ng-template script tag. but it's fails to work. how to apply html from the script tag?
Here is my code and html:
js part :
//our root app component
import {Component} from 'angular2/core'
#Component({
selector: 'my-app',
providers: [],
templateUrl: "template.html", //this is the id.
directives: []
})
export class App {
public title = "My Title";
private userName = "Test Name";
constructor() {
this.name = 'Angular2'
}
}
HTML part :
<body>
<my-app>loading...</my-app>
//template declared
<script type="text/ng-template" id="template.html">
<h2>{{title}}</h2>
<div>
<h2>Hello {{name}}</h2>
<h2>{{userName}}</h2>
</div>
</script>
</body>
I am getting a error :
Failed to load template.html
What is the correct way to use it?
Unfortunately, this is not, nor will be, supported in Angular 2 :\ https://github.com/angular/angular/issues/6126
In Angular 1.x, we could insert HTML in real-time by using the HTML tag ng-bind-html, combined with the JavaScript call $sce.trustAsHTML(). This got us 80% of th way there, but wouldn't work when Angular tags were used, such as if you inserted HTML that used ng-repeat or custom directives.
To get that to work, we could use a custom directive that called $compile.
What is the equivalent for all of this in Angular 2? We can bind using [inner-html] but this only works for very simple HTML tags such as <b>. It doesn't transform custom angular 2 directives into functioning HTML elements. (Much like Angular 1.x without the $compile step.) What is the equivalent of $compile for Angular 2?
In Angular2 you should use DynamicComponentLoader to insert some "compiled content" on the page. So for example if you want to compile next html:
<div>
<p>Common HTML tag</p>
<angular2-component>Some angular2 component</angular2-component>
</div>
then you need to create component with this html as a template (let's call it CompiledComponent) and use DynamicComponentLoader to insert this component on the page.
#Component({
selector: 'compiled-component'
})
#View({
directives: [Angular2Component],
template: `
<div>
<p>Common HTML tag</p>
<angular2-component>Angular 2 component</angular2-component>
</div>
`
})
class CompiledComponent {
}
#Component({
selector: 'app'
})
#View({
template: `
<h2>Before container</h2>
<div #container></div>
<h2>After conainer</h2>
`
})
class App {
constructor(loader: DynamicComponentLoader, elementRef: ElementRef) {
loader.loadIntoLocation(CompiledComponent, elementRef, 'container');
}
}
Check out this plunker
UPD You can create component dynamically right before the loader.loadIntoLocation() call:
// ... annotations
class App {
constructor(loader: DynamicComponentLoader, elementRef: ElementRef) {
// template generation
const generatedTemplate = `<b>${Math.random()}</b>`;
#Component({ selector: 'compiled-component' })
#View({ template: generatedTemplate })
class CompiledComponent {};
loader.loadIntoLocation(CompiledComponent, elementRef, 'container');
}
}
I personally don't like it, it's look like a dirty hack to me. But here is the plunker
PS Beware that at this moment angular2 is under active development. So situation can be changed at any time.
DynamicComponentLoader is deprecated, you can use ComponentResolver instead
You could use this directive, add pipes if you need additional data manipulation. It also allows for lazy loading, you don't need it in your case, but it's worth mentioning.
Directive(I found this code and made some changes, you can do that too to make it fit your taste or use it as is):
import { Component, Directive, ComponentFactory, ComponentMetadata, ComponentResolver, Input, ReflectiveInjector, ViewContainerRef } from '#angular/core';
declare var $:any;
export function createComponentFactory(resolver: ComponentResolver, metadata: ComponentMetadata): Promise<ComponentFactory<any>> {
const cmpClass = class DynamicComponent {};
const decoratedCmp = Component(metadata)(cmpClass);
return resolver.resolveComponent(decoratedCmp);
}
#Directive({
selector: 'dynamic-html-outlet',
})
export class DynamicHTMLOutlet {
#Input() htmlPath: string;
#Input() cssPath: string;
constructor(private vcRef: ViewContainerRef, private resolver: ComponentResolver) {
}
ngOnChanges() {
if (!this.htmlPath) return;
$('dynamic-html') && $('dynamic-html').remove();
const metadata = new ComponentMetadata({
selector: 'dynamic-html',
templateUrl: this.htmlPath +'.html',
styleUrls: [this.cssPath]
});
createComponentFactory(this.resolver, metadata)
.then(factory => {
const injector = ReflectiveInjector.fromResolvedProviders([], this.vcRef.parentInjector);
this.vcRef.createComponent(factory, 0, injector, []);
});
}
}
Example how to use it:
import { Component, OnInit } from '#angular/core';
import { DynamicHTMLOutlet } from './../../directives/dynamic-html-outlet/dynamicHtmlOutlet.directive';
#Component({
selector: 'lib-home',
templateUrl: './app/content/home/home.component.html',
directives: [DynamicHTMLOutlet]
})
export class HomeComponent implements OnInit{
html: string;
css: string;
constructor() {}
ngOnInit(){
this.html = './app/content/home/home.someTemplate.html';
this.css = './app/content/home/home.component.css';
}
}
home.component.html:
<dynamic-html-outlet [htmlPath]="html" [cssPath]="css"></dynamic-html-outlet>
After reading a lot, and being close of opening a new topic I decided to answer here just to try to help to others. As I've seen there are several changes with the latest version of Angular 2. (Currently Beta9)
I'll try to share my code in order to avoid the same frustration I had...
First, in our index.html
As usual, we should have something like this:
<html>
****
<body>
<my-app>Loading...</my-app>
</body>
</html>
AppComponent (using innerHTML)
With this property you will be able to render the basic HTML, but you won't be able to do something similar to Angular 1.x as $compile through a scope:
import {Component} from 'angular2/core';
#Component({
selector: 'my-app',
template: `
<h1>Hello my Interpolated: {{title}}!</h1>
<h1 [textContent]="'Hello my Property bound: '+title+'!'"></h1>
<div [innerHTML]="htmlExample"></div>
`,
})
export class AppComponent {
public title = 'Angular 2 app';
public htmlExample = ' <div>' +
'<span [textContent]="\'Hello my Property bound: \'+title"></span>' +
'<span>Hello my Interpolated: {{title}}</span>' +
'</div>'
}
This will render the following:
Hello my Interpolated: Angular 2 app!
Hello my Property bound: Angular 2 app!
Hello my Interpolated: {{title}}
AppComponent Using DynamicComponentLoader
There is a little bug with the docs, documented in here. So if we have in mind that, my code should look now like this:
import {DynamicComponentLoader, Injector, Component, ElementRef, OnInit} from "angular2/core";
#Component({
selector: 'child-component',
template: `
<div>
<h2 [textContent]="'Hello my Property bound: '+title"></h2>
<h2>Hello my Interpolated: {{title}}</h2>
</div>
`
})
class ChildComponent {
title = 'ChildComponent title';
}
#Component({
selector: 'my-app',
template: `
<h1>Hello my Interpolated: {{title}}!</h1>
<h1 [textContent]="'Hello my Property bound: '+title+'!'"></h1>
<div #child></div>
<h1>End of parent: {{endTitle}}</h1>
`,
})
export class AppComponent implements OnInit{
public title = 'Angular 2 app';
public endTitle= 'Bye bye!';
constructor(private dynamicComponentLoader:DynamicComponentLoader, private elementRef: ElementRef) {
// dynamicComponentLoader.loadIntoLocation(ChildComponent, elementRef, 'child');
}
ngOnInit():any {
this.dynamicComponentLoader.loadIntoLocation(ChildComponent, this.elementRef, 'child');
}
}
This will render the following:
Hello my Interpolated: Angular 2 app!
Hello my Property bound: Angular 2 app!
Hello my Property bound: ChildComponent title
Hello my Interpolated: ChildComponent title
End of parent: Bye bye!
I think all you have to do is set the element you want to have compiled html with the [innerHTML]="yourcomponentscopevar"
Angular provided DynamicComponentLoader class for loading html dynamically. DynamicComponentLoader have methods for inserting components. loadIntoLocation is one of them for inserting component.
paper.component.ts
import {Component,DynamicComponentLoader,ElementRef,Inject,OnInit} from 'angular2/core';
import { BulletinComponent } from './bulletin.component';
#Component({
selector: 'paper',
templateUrl: 'app/views/paper.html'
}
})
export class PaperComponent {
constructor(private dynamicComponentLoader:DynamicComponentLoader, private elementRef: ElementRef) {
}
ngOnInit(){
this.dynamicComponentLoader.loadIntoLocation(BulletinComponent, this.elementRef,'child');
}
}
bulletin.component.ts
import {Component} from 'angular2/core';
#Component({
selector: 'bulletin',
templateUrl: 'app/views/bulletin.html'
}
})
export class BulletinComponent {}
paper.html
<div>
<div #child></div>
</div>
Few things you need to take care of :
Don't call loadIntoLocation inside the constructor of class . Component view is not yet created when component constructor is called. You will get error -
Error during instantiation of AppComponent!. There is no component
directive at element [object Object]
Put anchorName #child in html otherwise you will get error.
Could not find variable child
Have a look at this module https://www.npmjs.com/package/ngx-dynamic-template
After a long research, only this thing helped me. The rest of the solutions seems to be outdated.
