Of course you're not limited to just the click event as the v-on directive accepts the common Javascript events such as v-on:mouseover, v-on:keydown, v-on:submit, v-on:keypress, etc... or even your own custom defined events.
Since you will find yourself using the v-on:* directive quite frequently when developing, Vue provides us with a shorthand notation denoted by the @ symbol and you can simply replace this statement in our previous example:
<button v-on:click="sayHello">Hey there!</button>
with an equivalent @ version:
<button @click="sayHello">Hey there!</button>
