To capture key events on a canvas in Vue.js, you can add an event listener to the canvas element in your Vue component. Here's an example of how you can capture key events on a canvas in Vue.js:

  1. Add a ref attribute to your canvas element in the template section of your Vue component:
1
2
3
<template>
  <canvas ref="canvas"></canvas>
</template>


  1. In the mounted() method of your Vue component, add an event listener to the canvas element to capture key events:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
export default {
  mounted() {
    this.$refs.canvas.addEventListener('keydown', this.handleKeyDown);
  },
  methods: {
    handleKeyDown(event) {
      // Handle key event here
      console.log(event.key);
    }
  }
}


  1. Don't forget to remove the event listener when the component is destroyed to avoid memory leaks:
 1

 5
 6
 7
 8
 9
10
11
12
13
14
export default {
  mounted() {
    this.$refs.canvas.addEventListener('keydown', this.handleKeyDown);
  },
  beforeDestroy() {
    this.$refs.canvas.removeEventListener('keydown', this.handleKeyDown);
  },
  methods: {
    handleKeyDown(event) {
      // Handle key event here
      console.log(event.key);
    }
  }
}


With these steps, you should be able to capture key events on a canvas in Vue.js. Make sure to adjust the key event handling logic in the handleKeyDown method to suit your application's needs.
