![]() One thing you should keep in mind when managing form submissions in JavaScript apps is that you must utilize the native preventDefault() function of the submit event before running your form handling function. The following code illustrates how you can pop an alert message when form data is submitted: Form Events in Vueįorm events are triggered by form actions such as submission, input field change and lots more - using event names like :submit, :change, :reset. The key event modifier follows the structure: Key event modifiers in Vue offer extensive support for listening to keyboard inputs. Taking a look at the code above, you will notice we added key event modifiers - such as. You can register an event when a user is pressing down a key ( keydown), starts to presses a key ( keypress), or releases a key ( keyup): įor instance, suppose we want an alert to show what is typed into an input fields when we press the enter key on our keyboard. Keyboard events are triggered when a user types a particular button on the keyboard. It defines a DOM event it listens to and assigns a JavaScript function that runs when the event is detected: Īlternatively, we can make use of the symbol and avoid using v-on as seen below: Vue uses the v-on directive to catch and handle events. We will learn how to handle the click, submit, scroll, and some keyboard events. Event handling enables us to run JavaScript as a response to DOM events. In this article, we will explore how to handle events in Vue using the v-on directive. Events can appear either as user input or we can manually create them in the code and emit them when needed. It has an event handling mechanism that allows you to catch and handle events from within each independent component file. ![]() These functions are known as event handlers. Interactive and reactive applications are, in essence, built around the concept of reacting to events - each time an event is detected, an application calls a corresponding function that handles the detected event. ![]() Generally speaking, an event is a signifier of an interaction between a user and our application - clicking, typing on a keyboard, and so on.

On line 3, I’ve triggered an event (method) called onF2. You can then use the key code in any template as follows: export default Code language: HTML, XML ( xml ) You’d notice that I’ve added a ke圜ode as f2 with a value of 113. Here’s my main.js file: import Vue from "vue" You can then access the keycode to trigger any event using the given name. Here, in this example I’ll show you how you can register a key code and give it a name, as an alias. I’ve previously written an article on controlled combination of mouse and keyboard key presses to trigger events. That means, you can use something like v-on:keyup.enter or to trigger an event when the Enter key is pressed. Vue.js comes with many key code names out of the box.
