Vue.js Events
Vue.js is a popular JavaScript framework that is used to build user interfaces. It has an extensive event system that allows developers to create interactive applications. In this page, we’ll discuss the Vue.js events in detail.
Syntax
To capture events in Vue.js, you can use the v-on
directive. The syntax for this directive is as follows:
<!-- shorthand -->
<button @click="doSomething"></button>
<!-- long-form -->
<button v-on:click="doSomething"></button>
The @
symbol is shorthand for v-on:
.
Example
<template>
<button v-on:click="incrementCounter">{{ counter }}</button>
</template>
<script>
export default {
data() {
return {
counter: 0
}
},
methods: {
incrementCounter() {
this.counter++;
}
}
}
</script>
Output
The counter
value will be incremented each time the user clicks the button.
Explanation
In the above example, we have a simple button element that has the v-on:click
directive attached to it. When the user clicks the button, the incrementCounter
method is called. The method simply increments the counter
data property.
