You can use reactive form and create a formGroup but just to make it simple you can use formControl.

components

  selectControl:FormControl = new FormControl()

template

<article>
    <h1>What is your gender?</h1>
    <h2><span>Select a gender:</span></h2>
    <select [formControl]="selectControl">
        <option value="1">Male</option>
        <option value="2">Female</option>
        <option value="3">Intersex</option>
        <option value="4">Trans</option>
        <option value="5">Others</option>
    </select>
    <p><span>You selected: </span><b>{{selectControl.value}}</b></p>
    <button (click)="selectControl.setValue('4')">Set Value</button>
</article>

this may look alternative to ngModel but I just promote reactive forms

Comments
  • No need to add selectchangeHandler, because angular binds to that variable automatically. If you are going to process anything further on dropdown change then you can add that handler.
  • yes, you can use binding but what if in select tag you have an *ngIf e.g. <select class="form-control select1" id="Acquirer" name="Acquirer" (change)="updateMerchantAcquirer($event)"> <option *ngFor="let acquirer of acquirerList; let i = index" value={{i}}>{{acquirer.businessName}}</option> </select>
  • now you success get the value but what about set the value to the form or clear the form ?? my recommendation use angular forms solutions like template or reactive forms
