Summary of the method of monitoring keyboard keys on Vue page

In Vue pages, there are several ways to listen to keyboard keys. Here are at least five commonly used methods:

1. Use the @keydown or @keyup directive to bind keyboard key events.

<template>
  <div>
    <input type="text" @="handleEnterKey" />
  </div>
</template>
<script>
export default {
  methods: {
    handleEnterKey() {
      // Handle the Enter key press event    },
  },
};
</script>

2. Use the v-on command to bind keyboard key events.

<template>
  <div>
    <input type="text" v-on:="handleEnterKey" />
  </div>
</template>
<script>
export default {
  methods: {
    handleEnterKey() {
      // Handle the Enter key press event    },
  },
};
</script>

3. Use to monitor keyboard key events globally.

<template>
  <div></div>
</template>
<script>
export default {
  mounted() {
    ('keydown', );
  },
  beforeUnmount() {
    ('keydown', );
  },
  methods: {
    handleKeyDown(event) {
      if ( === 'Enter') {
        // Handle the Enter key press event      }
    },
  },
};
</script>

4. Use the vue-shortkey plug-in to monitor keyboard keys.

<template>
  <div>
    <input type="text" ="handleEnterKey" />
  </div>
</template>
<script>
import VueShortkey from 'vue-shortkey';
export default {
  directives: {
    shortkey: VueShortkey,
  },
  methods: {
    handleEnterKey() {
      // Handle the Enter key press event    },
  },
};
</script>

5. Use the keydown event listener.

<template>
  <div>
    <input type="text" ref="input" />
  </div>
</template>
<script>
export default {
  mounted() {
    this.$('keydown', );
  },
  beforeUnmount() {
    this.$('keydown', );
  },
  methods: {
    handleKeyDown(event) {
      if ( === 'Enter') {
        // Handle the Enter key press event      }
    },
  },
};
</script>

List of commonly used keyboard event listening in Vue page

The following is a list of commonly used keyboard event listening on Vue pages:

  • @keydown: Listen to the keyboard press event.
  • @keyup: Listen to keyboard lift event.
  • @keypress: Listen to keyboard key events, including pressing and lifting.
  • @: Listen to the event of the Enter key press.
  • @: Listen to the Tab key press event.
  • @: Listen to the Esc key press event.
  • @: Listen to the spacebar press event.
  • @: Listen to the event of the left arrow key press.
  • @: Listen to the right arrow key press event.
  • @: Listen to the event of the up arrow key press.
  • @: Listen to the down arrow key press event.
  • @: Listen to the delete key press event.
  • @: Listen to the event of the backspace key press.
  • @keydown.[key]: Listen to other specific key press events, such as @ listen to the letter A key press events.

Listen event component encapsulation

You can encapsulate a component called KeyboardEventListener to facilitate the call to keyboard event monitoring. Here is an example:

<template>
  <div></div>
</template>
<script>
export default {
  name: 'KeyboardEventListener',
  props: {
    event: {
      type: String,
      required: true,
    },
  },
  mounted() {
    (, );
  },
  beforeUnmount() {
    (, );
  },
  methods: {
    handleEvent(event) {
      this.$emit('keydown', event);
    },
  },
};
</script>

When using it, you can introduce and use the KeyboardEventListener component where you need to listen for keyboard events, and pass the event name to listen for it through the event attribute, and listen for the keydown event to handle specific key logic. For example:

&lt;template&gt;
  &lt;div&gt;
    &lt;KeyboardEventListener event="" @keydown="handleEnterKey" /&gt;
  &lt;/div&gt;
&lt;/template&gt;
&lt;script&gt;
import KeyboardEventListener from '@/components/';
export default {
  components: {
    KeyboardEventListener,
  },
  methods: {
    handleEnterKey(event) {
      // Handle the Enter key press event    },
  },
};
&lt;/script&gt;

By encapsulating components, they can be directly introduced and used where keyboard events need to be monitored, avoiding duplicate listening and processing logic, and improving code maintainability and reusability.
