1.示例

点击转换

得到的arrayBuffer对象文本：

<template>
  <div class="flex flex-col">
    <div class="flex gap-8px">
      <el-input placeholder="请输入要文本" v-model="text" />
      <el-button class="flex-none" :disabled="!text" @click="onEncode">点击转换</el-button>
    </div>

    <el-divider />
    <div class="mt-4px max-h-400px overflow-y-auto">得到的arrayBuffer对象文本：{{ arrayBufferString }}</div>
  </div>
</template>

<script>
import { textToArrayBuffer } from 'sf-utils2'

export default {
  data() {
    return {
      text: '',
      arrayBufferString: ''
    }
  },

  methods: {
    async onEncode() {
      const arrayBuffer = await textToArrayBuffer(this.text)
      this.$message.warning('请查看控制台')
      console.log(arrayBuffer)
      this.arrayBufferString = JSON.stringify(Array.from(new Uint8Array(arrayBuffer)))
    }
  }
