Having trouble with the @keyup event not functioning properly in Vue?

Question

Having trouble with the @keyup event not functioning properly in Vue?

I'm attempting to trigger a method when the enter key is pressed, but for some reason it's not working. Here's the code snippet:

<template>
  <div>
    <button @click="callEvent" @keyup.enter="callEvent"> Click </button>
  </div>
</template>

<script>
export default{
  methods:{
    callEvent(){
      console.log("The event has been triggered");
    }
  }
}
</script>

javascript vue.js

Answer №1

When it comes to triggering the click event using the ENTER key, you don't need much code. Simply add @click="callEvent" to your button element and it will work seamlessly as the focus is already on the button:

var app = new Vue({
  el: "#app",
  methods: {
    callEvent() {
      console.log("Event called");
    }
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.2/vue.min.js"></script>
<div id="app">
  <button @click="callEvent">Enter</button>
</div>

If you want the ENTER key to trigger the button even without focus, you can bind the event to the window object within the mounted handler like so:

var app = new Vue({
  el: "#app",
  methods: {
    callEvent() {
      console.log("Event called");
    }
  },
  mounted() {
    window.addEventListener('keyup', function(event) {
      if (event.keyCode === 13) { 
        app.callEvent();
      }
    });
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.2/vue.min.js"></script>
<div id="app">
  <button>Enter</button>
</div>

In case you are using Single File Components, remember that the instance is exposed by the this keyword, allowing you to call component methods in the desired handler:

export default {
  methods: {
    callEvent() {
      console.log('Event called')
    }
  },
  mounted() {
    window.addEventListener('keyup', event => {
      if (event.keyCode === 13) { 
        this.callEvent()
      }
    })
  }
}

Buttons do not trigger the keyup event when pressed. Even if you focus on a button and press enter, it will register as a click event instead of keyup.enter.

You can try attaching the event to an input element for it to function properly.

Another approach would be using jQuery (or Vanilla JS) to listen for the keydown event on the body element, and then manually triggering the Vue method with app.callEvent().

var app = new Vue({
  el: "#app",
  methods: {
    callEvent() {
      console.log("Event called");
    }
  },
  mounted() {
    var self = this;
    window.addEventListener('keyup', function(event) {
      if (event.keyCode === 13) { 
        self.callEvent();
      }
    });
  }
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.2/vue.min.js"></script>
<div id="app">
  <template>
  <div>
    <button @click="callEvent"> Click </button>
  </div>
  <input type="text"  @keyup.enter="callEvent" />
</template>

</div>

My experience with using native JS and window.addEventListener led to inconsistent results. Fortunately, VueJS has built-in support for customizing keyboard event behavior https://v2.vuejs.org/v2/guide/events.html#Key-Modifiers

This approach worked much better for me, especially when I needed different actions for the tab key.

You can achieve custom input behavior by defining modifiers for each key press and release events like this:

    <input 
        type="text" 
        class="form-control" 
        placeholder="Start typing to search..." 
        v-model="search_text" 
        @focus="searchFocus" 
        @blur="searchFocusOut"
        v-on:keyup.enter="nextItem"
        v-on:keyup.arrow-down="nextItem"
        v-on:keyup.arrow-up="nextItem"
        v-on:keydown.tab="nextItem"
    >

In the 'nextItem' function, you can access the event object and determine which key was pressed or create separate functions for each key modifier.
