How to use v-on:click.native to bind native events in Vue

Vue is a popular JavaScript framework that can quickly build a responsive user interface and provides great help for website development. In Vue, we often need to use event binding to respond to user operations. When we need to bind native events, we can use v-on:click.native.

v-on:click.native is a directive provided by Vue. When used in a template, it instructs Vue to bind a native click event to the current element. This command can also be used for other events, such as keyup, keydown, etc. This means that we can use native JavaScript events in Vue to handle user interactions.

When using v-on:click.native, we need to pay attention to some details. First, you need to use this instruction in the template of the Vue component:

<template>
  <div v-on:click.native="handleClick">点击我</div>
</template>

Here we bind a click event to a div element and specify the event handler function as handleClick. It should be noted that v-on:click.native is bound to the native DOM element, not to the custom element of the Vue component.

Secondly, we can define a Vue method as usual, which will be called to perform the operation:

<script>
export default {
  methods: {
    handleClick(event) {
      console.log('点击事件触发：', event);
    }
  }
}
</script>

Here we define a method named handleClick, which receives an event parameter . We can access the event object in methods to get details about the event. In this example, we use the console.log() function to log the message that triggered the event.

Finally, we need to understand an important concept: v-on:click.native is not bound to the element of the Vue component template, but to the root element of the Vue component. This means that if we need to bind v-on:click.native to a rendered sub-element, we need to set this sub-element as the root element in the vue instance. As shown below:

<script>
import Vue from 'vue';
import ChildComponent from './ChildComponent.vue';

export default {
  components: {
    ChildComponent,
  },
  mounted() {
    const child = new Vue({
      el: this.$refs.childRef,
      methods: {
        handleClick(event) {
          console.log('点击事件触发：', event);
        }
      }
    });

    this.$refs.childRef.child = child;
  }
}
</script>

<template>
  <div>
    <ChildComponent ref="childRef">
      <div v-on:click.native="child.handleClick">点击我</div>
    </ChildComponent>
  </div>
</template>

In this example, we use a child component ChildComponent and bind the v-on:click.native event to the dom element of the child component. We use $refs to reference the subcomponent, set it as the root element, and then bind the event handler to the vue instance.

Summary

The v-on:click.native directive allows us to use native JavaScript events in Vue to respond to user operations. It should be noted that this directive is bound to the root element of the Vue component, not to the custom Vue component element. When using it, we need to use the methods attribute to define the method. In this method, we can access the event object to get the details of the event.
