Discover the power of Vue.js 3 by seamlessly integrating anonymous functions within event handlers

Is it possible to invoke an anonymous function within an event handler in Vue.js 3?

I came across several options on various websites:

<button @click="return function() { console.log('test')}()">Click me</button>

<button @click="() => { console.log('test') }">Click me</button> //ES6

<button @click="(function(){ console.log('Test'); })();">Click me</button>

Unfortunately, none of these methods appear to be effective. It's possible that they were designed for use with Vue.js 2, but I cannot confirm this.

Answer №1

One issue arises when console is not defined in the template. To solve this, you can either define it as a property in your data object or call a method that utilizes the console:

<button @click="() => { logDatat('some data log') }">Click me</button> 

<button @click="() => { myConsole.log }">Click me</button> 

....

data(){
  return {
     myConsole : console
   }
}

All three syntaxes are valid and can be seen in action in this demo:
