How to use Vue to implement simulated handwritten signature effects

Introduction: In many applications, users are required to perform signature operations, such as electronic contracts, electronic forms, etc. In order to improve the user experience, we can use the Vue framework to implement a special effect that simulates a handwritten signature. This article will introduce in detail how to use Vue to simulate the effect of handwritten signatures, and provide specific code examples.

1. Create a Vue project

First, make sure that the Vue CLI has been installed, then execute the following command in the terminal to create a new Vue project:

vue create signature-effect

Enter the project directory:

cd signature-effect

2. Add necessary dependencies

In the Vue project, we need to use some libraries to achieve handwritten signature effects. Execute the following commands in the terminal to install these libraries:

npm install signature_pad --save
npm install vue-signature-pad --save

3. Create signature components

Create a file named# in the src/components directory ##SignaturePad.vue component file and copy the following code into it:

<template>
  <div>
    <canvas ref="canvas"></canvas>
    <button @click="clear">清除</button>
  </div>
</template>

<script>
  import SignaturePad from 'signature_pad';

  export default {
    mounted() {
      this.signaturePad = new SignaturePad(this.$refs.canvas);
    },
    methods: {
      clear() {
        this.signaturePad.clear();
      }
    }
  }
</script>

<style scoped>
  canvas {
    border: 1px solid #ccc;
  }
</style>

Use the signature component in the main component

In

src /App.vue file, replace the content in the

Run the project

Execute the following command in the terminal to start the Vue project:

npm run serve

Open

http://localhost:8080 in the browser, you will see a signature area and clear button page. In the signature area, you can use the mouse or touch screen to simulate a handwritten signature. Click the Clear button to clear the signature area.

Summary:

Through the above steps, we used Vue to build a page that simulates handwritten signature effects. By introducing the SignaturePad library and custom SignaturePad components, we implement basic handwritten signature functionality. You can further expand on this basis, such as adding save, undo and other functions to meet specific business needs.
