Tag event binding in Vue

In Vue.js, you can pass v-on Directive binds DOM events to methods in the Vue instance.

Syntax:

<code><标签名 v-on:事件="方法名" other-props="...">...</标签名></code>

Specific steps:

1. Select the label to which the event will be bound: Determine the elements that need to listen for events.
2. Add the v-on directive: Use the v-on directive to specify the event type and method of handling the event. For example, v-on:click is used to bind click events.
3. Specify method name: Specify the Vue method to be called in the value of the v-on directive. The method name must be a method in the Vue instance.

Example:

The following example shows how to bind a click event handler:

<code class="html"><button v-on:click="handleClick">点击我</button></code>

<code class="javascript">// Vue 实例
const app = new Vue({
  methods: {
    handleClick() {
      console.log("按钮被点击了！");
    }
  }
});</code>

When a button is clicked, ## The #handleClick method will be called and output a message to the console.

Note:

Event names should follow camel case (e.g.
• v-on:click), not hyphens form (e.g. v-on:on-click).
Vue uses lowercase letters to bind events, such as
• v-on:click instead of v-on:onClick.
If you want to bind an event that requires modifiers (for example,
• v-on:click.stop), you can add a period (.) and modifiers after the event name.
