ngfor

Here's my object (It has n number of dynamic keys. I've only shown two in the example below) let obj = { abc:["some text", "some more text"], xyz:["more text", "what do you think?", "I'm tired now"] } Here's my attempt to loop throw the above and print all the values <div *ngFor='let item of obj ; let i = index;'> <p *ngFor="let value of obj.i">{{value}} </div> But the above doesn't appear to work. What am I doing wrong and what's the correct syntax? You could do something like this: <li *ngFor="let o of obj"> <p *ngFor="let objArrayElement of generateArray(o)"> {{objArrayElement}} </p> </li>

I'm trying Angular 2 and I noticed that performance on Internet Explorer 11 is dramatically slow while cycling with *ngFor over 1500 items. It takes about 25sec with IE11 whereas less then 1sec on other browsers. Pausing the debugger I noticed that the code constantly calls isNan function in es6-shim.js. Here the call stack: A working plnkr here: http://plnkr.co/edit/sEujClHmuCbrydIiYQYL?p=preview . The code is very simple: <ul *ngFor="#item of items"> <li>Item: {{item.itemKey}}</li> </ul> //Load items simulating remote load setTimeout(function(){ for (let i = 0; i < 1500; i++) { self.items

I've seen many animation tutorials for the entering or leaving elements ("New element" on the image below), but the rest of elements (Element 1 and 2), that are pushed apart usually just teleport to their new location. Is there a way to animate the other elements to move away nicely, like depicted in the attached image? You can use angular2 animation API to achieve it. Plunker Example @Component({ selector: 'my-app', template: ` <div class="container"> <div *ngFor="let item of items; let i = index" class="item" (click)="remove(i)" [@anim]="item.state"> {{ item.name }} </div> </div> <div class=

I'm trying using the ngFor on my select DropDownList. Have loaded in the options which should be in the dropdown. The code you see here: <div class="column small-12 large-2"> <label class="sbw_light">Title:</label><br /> <select [(ngModel)]="passenger.Title"> <option *ngFor="#title of titleArray" [value]="title.Value">{{title.Text}}</option> </select> </div> Based on this code, it produces a dropdown which look like this image. The problem is that I want to set one of them "Mr or Mrs" as the active one based on the passenger.Title which is a string either "Mr" or "Mrs". Any can help see what I

Below is angular2 simple front end page:: <table class="table"> <tr> <th>title</th> <th>description</th> </tr> <tr *ngFor="let notes of Note"> <td>{{notes.title}}</td> <td>{{notes.body}}</td> </tr> </table> Below is component code:: in which Note is having export class Note { noteId: number ; title: String ; body: String ; color: String ; isArchive: boolean ; isPinned: boolean ; isTrash: boolean ; } notes:Note[]=[]; ngOnInit() { this.getAllNotes(); } //get all anotes getAllNotes(){ this.noteService.getNotes() .subscribe( // notes => { //tried not working // this.notes = notes; // console.log

I have to display a table and call a function for every row of table and the function called once for a row. <tr *ngFor="let item of mf.data" > <td > <button (click)="remove(item)" class="btn btn-danger">x</button> </td> <td>{{item.name}}</td> <td>{{item.email}}</td> <td class="text-right">{{item.age}}</td> <td>{{item.city | uppercase}}</td> </tr> Please suggest how will I implement this functionality?? You can add a directive @Directive({ selector: '[invoke]'}) class InvokeDirective { @Output() invoke:EventEmitter = new EventEmitter(); ngAfterContentInit() { this.invoke.emit(null); } } And
