How to call a function in VUE template?

Here, we will learn on how to call a function in vue template.

Define and call a function in vue template.

First let’s create the data and the methods in vue.

In script:

<script>
export default {
      data(){
        return{
          number: 0
        }
      },
      methods:{
        increaseNumber(){
          this.number ++
        }
      }
}
</script>

Here i have created a function call increaseNumber(), which will increment the number with + 1 whenever we call the function with a click Event.

In template:

<template>
  <div>
    <button @click="increaseNumber()">Increase Number</button>
    The Number is : {{ number }}
  </div>
</template>

Now whenever we click the function from the template, it will call the function and it will increase the value of the number by + 1.
