Textarea typing issue in ngFor in Angular 6

Textarea typing issue in ngFor in Angular 6

hop of those help? You bind all data into: [(ngModel)]=postAnswer.Description so text appears in all textareas. You should add some kind of filter with ID of textarea, or use array to keep all textareas, like [(ngModel)]=postAnswer[id].Description;
The simplest working example: https://stackblitz.com/edit/angular-yyvqvg?embed=1&file=src/app/app.component.html
code :
public tempVal = {};
public addNewAnswer(id, value) {
   console.log('ID', id);
   console.log("VAL", value);
<li class="media media-sm" *ngFor="let question of test; let i = index;">
    <textarea rows="3" name="answer" [(ngModel)]="tempVal[i]" class="form-control bg-silver" placeholder="Answer Here..."
        ngModel #answer="ngModel"></textarea>
    <button class="btn btn-primary" type="submit" (click)="addNewAnswer(question, tempVal[i])">BUTTON</button>

Angular 2. Issue with *ngFor, when i use Pipe

Hope that helps Since you load your data asynchronously using a promise, they are null at the beginning (before the first callback defined in the then method is called).
You need to check if the are parameter is null in your pipe. If so you shouldn't execute the "order by" processing...
code :
    name: 'orderBy',
    pure: false

export class orderBy implements PipeTransform {
    transform(arr: any[], orderFields: string[]): any {
      if (arr==null) {
        return null;

this will help Solution:
Run CODE snippet below & type as the textarea appears.
code :
var delay = 3000; // that's 3 seconds of not typing
var timer = null;
function isTyping() {
  var value = document.getElementById('text').value;
  if( value ) {
    document.getElementById('send').innerHTML = "Typing";
    document.getElementById("send").className = "typing";
    timer = setTimeout(notTyping, delay); 
  else {

function notTyping() {
  document.getElementById('send').innerHTML = "Not Typing";
  document.getElementById("send").className = "not-typing";
#send {
  display: block;
  width: 200px;
  height: 20px;
.not-typing {
  background-color: yellow;
.typing {
  background-color: red;
<textarea class="type-message" oninput="isTyping()" id="text" name="textarea" cols="45" rows="5"></textarea>
<div id="send" class="not-typing">Not Typing</div>

wish of those help The name5 value set by the user is not getting reset for the next question.
You need to have 2 way binding to reset the value once it is sent for each question.
code :
<ion-select name="{{question?.name}}" placeholder="Select" [(ngModel)]="selectedIndex"> 
<ion-option *ngFor="let i of inputs;let index = index" value="{{index}}">{{i.display}}</ion-option>
