问题描述

我正在尝试在组件中使用on click指令,但它似乎不起作用。当我点击组件时,当我在控制台中获得测试点击时,会发生无关紧要的事情。我在控制台中没有看到任何错误,所以我不知道我做错了什么。

I'm trying to use the on click directive inside a component but it does not seem to work. When I click the component nothings happens when I should get a 'test clicked' in the console. I don't see any errors in the console, so I don't know what am I doing wrong.

index.html

<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">
    <title>vuetest</title>
  </head>
  <body>
    <div id="app"></div>
    <!-- built files will be auto injected -->
  </body>
</html>

App.vue

<template>
  <div id="app">
    <test v-on:click="testFunction"></test>
  </div>
</template>

<script>
import Test from './components/Test'

export default {
  name: 'app',
  methods: {
    testFunction: function (event) {
      console.log('test clicked')
    }
  },
  components: {
    Test
  }
}
</script>

Test.vue(组件)

<template>
  <div>
    click here
  </div>
</template>

<script>
export default {
  name: 'test',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  }
}
</script>


推荐答案

如果你想听一个原生事件组件的根元素,您必须使用 .native 修饰符 v-on ,如下所示:

If you want to listen to a native event on the root element of a component, you have to use the .native modifier for v-on, like following:

<template>
  <div id="app">
    <test v-on:click.native="testFunction"></test>
  </div>
</template>

或简写,如评论中所示,您也可以这样做:

or in shorthand, as suggested in comment, you can as well do:

<template>
  <div id="app">
    <test @click.native="testFunction"></test>
  </div>
</template>
