Update Angular ngModel of a Select changed by jQuery


Update Angular ngModel of a Select changed by jQuery

seems to work fine You can use scope.$eval() to evaluate a string as code with the current scope as the context. It's safe to use because it will return undefined if the string happens not to reference an existing property, and the scope is the context for the evaluation, so trying to access properties not on the scope (like window) will also return undefined. You can use it like so:
code :
var scope = angular.element(optionObj).scope();

scope.$evalAsync(function(optionObj) {

    var ngModelAttr = optionObj.attr("ng-model");

    scope.$eval(ngModelAttr + " = '' ");

}(optionObj));

I think the issue was by ths following , I'm trying to create a select control that will bind the value to an Object and on change I can get access to the selected object. , You should define select inputs/outputs as following:
code :
<select [(ngModel)]="selected" (ngModelChange)="onChange()">
  <option *ngFor="let d of data" [ngValue]="d">
    {{d.name}}
  </option>
</select>

I wish this help you I am trying to make that after new value is selected, I call eventChange() function and restore selected value to default. But what happens: ngModel value updates, but selected value stays the same. How should I do that selected value and ngModel value would be the same? , Use ngModelChange and you don't need [ngValue]
code :
<select [(ngModel)]="selectedValue"
       (ngModelChange)="eventChange()"

This might help you Change ([ngModel])="selectedValue" to [(ngModel)]="selectedValue"
Just like the docs say:
code :
import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  template: `
  <select type="submit" [ngModel]="selectedValue" (ngModelChange)="onSelectedChange($event)">
    <option *ngFor="let option of options">{{ option }}</option>
  </select>

  {{ selectedValue }}
  ` ,
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  selectedValue = 1;
  options = [1,2,3]

  onSelectedChange(value: number) {
    // do something else with the value
    console.log(value);

    // remember to update the selectedValue
    this.selectedValue = value;
  }
}

fixed the issue. Will look into that further I want to update value of ngModel on click of a button using javascript. I have tried but it's not working. , Use Declare var $: any to use JQuery anywhere.
app.component.html
code :
{{ name }}
<p>
  <input type="text" [(ngModel)]="name" id="t">
</p>
<button type="button" (click)="test()">Clicx</button>
import { Component } from '@angular/core';
declare var $: any;
@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})
export class AppComponent  {
  name = 'Angular';

  test() {
    $("#t").val("Test Value");
  }
}

it fixes the issue Removing providers: [NgModel] from the @Directive attribute should fix the problem.
