Reacting to Keyup Events with Angular

Scenario

We have an input field and we want to log the contents of it whenever a keyup event occurs.

Approach

First define the components keyup event handler:

keyup(event) {
    console.log(event);
    console.log(this.fieldvalue);
}

Note that we are logging the value both from the event that the handler receives and the fieldvalue that we bind in the component declaration.

Next declare the input field in the component template (Note that the event must start with $ as in $event ):

<input placeholder="Type stuff ..." [value]="fieldvalue" (keyup)="keyup($event.target.value)">
