Using TypeScript to pass the text field ID to a function for clearing the text field with a button

I am looking for a way to improve the functionality of my web page featuring several buttons that will clear different text boxes on the same line. Currently, I am using separate functions for each button, but my goal is to streamline this process by utilizing a single function that can be customized through passing in the text field ID.

Here is an example of what I have now in HTML: 

<div class="col-sm-4">
     <input type="text" class="form-control" id="textField1" formControlName="textField1" />
</div>
      <button class="btn btn-danger" (click)="clearTextField('textField1')"><i class="fa fa-times"></i></button>

As shown above, I have a specific function for each text field like "clearTextField1()". Is there a way to achieve the desired outcome with just one function and dynamically pass in the text field ID when needed?

Answer №1

To make it work, simply include the formcontrolname in the click functions.

  <button class="btn btn-danger" (click)="clearTextField1('textField1')"><i class="fa fa-times"></i></button>

Here is the function that should be used:

clearTextField1(field:String): void {
    return this.form.controls[field].setValue('');
}
