Does Enter key trigger a click event?

In the code below removeSelectedCountry() should be called when a span element is clicked and handleKeyDown($event) should be called when there is a keydown event on a div.

@Component({
    selector: "wng-country-picker",
    template: `
    <ul class="CountryPicker-selected" *ngIf="selectedCountries.length > 0">
    <li *ngFor="let country of selectedCountries">
        <span class="Pill Pill--primary" (click)="removeSelectedCountry(country)">
        {{ country.name }}
        </span>
    </li>
    </ul> 
    <div (keydown)="handleKeyDown($event)" class="CountryPicker-input"></div>
`,
providers: [CUSTOM_VALUE_ACCESSOR]
})

But removeSelectedCountry() is called every time Enter key is pressed.

To make the code work, I had to change the click event to mousedown event. It works fine now.

Can anyone explain why the Enter key would trigger the click event?

@Component({
    selector: "wng-country-picker",
    template: `
    <ul class="CountryPicker-selected" *ngIf="selectedCountries.length > 0">
    <li *ngFor="let country of selectedCountries">
        <span class="Pill Pill--primary" (mousedown)="removeSelectedCountry(country)">
        {{ country.name }}
        </span>
    </li>
    </ul> 
    <div (keydown)="handleKeyDown($event)" class="CountryPicker-input"></div>
`,
providers: [CUSTOM_VALUE_ACCESSOR]
})

Adding class snipppet:

export class CountryPickerComponent {

private selectedCountries: CountrySummary[] = new Array();

private removeSelectedCountry(country: CountrySummary){
    // check if the country exists and remove from selectedCountries
    if (this.selectedCountries.filter(ctry => ctry.code === country.code).length > 0)
    {
        var index = this.selectedCountries.indexOf(country);
        this.selectedCountries.splice(index, 1);
        this.selectedCountryCodes.splice(index, 1);
    }
}

private handleKeyDown(event: any)
{
    if (event.keyCode == 13)
    {
       // action
    }
    else if (event.keyCode == 40)
    {
        // action
    }  
    else if (event.keyCode == 38)
    {
        // action
    }    
}

For ENTER key, why not use (keyup.enter):

@Component({
  selector: 'key-up3',
  template: `
    <input #box (keyup.enter)="values=box.value">
    <p>{{values}}</p>
  `
})
export class KeyUpComponent_v3 {
  values = '';
}

Here is the correct SOLUTION! Since the button doesn't have a defined attribute type, angular maybe attempting to issue the keyup event as a submit request and triggers the click event on the button.

<button type="button" ...></button>

Use (keyup.enter).

Angular can filter the key events for us. Angular has a special syntax for keyboard events. We can listen for just the Enter key by binding to Angular's keyup.enter pseudo-event.

For angular 6 there is a new way of doing it. On your input tag add

(keyup.enter)="keyUpFunction($event)"

Where keyUpFunction($event) is your function.

@Component({
  selector: 'key-up3',
  template: `
    <input #box (keyup.enter)="doSomething($event)">
    <p>{{values}}</p>
  `
})
export class KeyUpComponent_v3 {
  doSomething(e) {
    alert(e);
  }
}

This works for me!

<form (keydown)="someMethod($event)">
     <input type="text">
</form>

someMethod(event:any){
   if(event.keyCode == 13){
      alert('Entered Click Event!');
   }else{
   }
}

What personally me fount usable for me is:

(mousedown)="callEvent()" (keyup.enter)="$event.preventDefault()

keyup.enter prevents the event from triggering on keyup, but it still occurs for keydown, that works for me.
