Enter with @keyup event not working in Vue
The click event already triggers with the ENTER key (it also triggers with Space in some browsers, like Chrome for desktop). So, your code only needs a @click="callEvent" and everything works well since 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 that any ENTER triggers the button even if it isn't with focus, you should bind the event to the window object, which can be made inside the mounted handler:
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>Remember that if you're using Single File Components, the instance is exposed by the this keyword, which can be used to call component methods inside the desired handler:
export default { methods: { callEvent() { console.log('Event called') } }, mounted() { window.addEventListener('keyup', event => { if (event.keyCode === 13) { this.callEvent() } }) }}
Buttons don't have keyup event on them. Even when you have focus on the button, and hit enter, it will be considered a click event, instead of keyup.enter.
Try binding the event to an input and it'd work.
Alternatively, you could use jQuery (or Plain JS) to bind for keydown event on the body element, and trigger the Vue method by calling 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>Updated to use mounted instead of relying on jQuery - as per Erick Petrucelli's answer as it allows referring to the Vue component without the global variable.
I experienced inconsistent results when using native JS with window.addEventListener. VueJS natively supports modifying behavior for keyboard events https://vuejs.org/v2/guide/events.html#Key-Modifiers
This also worked a lot better in my case due to needing separate behavior for the tab key.
Your input can look like this with custom modifiers on each key up|down
<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" >Then inside NextItem you can reference the event, and get each key.. or write a separate function for each key modifier.
