el-checkbox实现单选

el-checkbox可以通过一些技巧实现单选，以下是两种实现方式：

1. 多个单选框实现单选

<template>
  <el-checkbox-group v-model="checkList" @change="statusChange">
    <el-checkbox label="1">1</el-checkbox>
    <el-checkbox label="2">2</el-checkbox>
    <el-checkbox label="3">3</el-checkbox>
    <el-checkbox label="4">4</el-checkbox>
  </el-checkbox-group>
</template>

<script>
export default {
  data() {
    return {
      checkList: []
    };
  },
  methods: {
    statusChange(value) {
      if (this.checkList.length > 1) {
        this.checkList.splice(0, 1);
      }
    }
  }
};
</script>

2. 两个多选框实现单选

<template>
  <el-checkbox-group v-model="status">
    <el-checkbox false-label="null" :true-label="1" name="status">启用</el-checkbox>
    <el-checkbox false-label="null" :true-label="2" name="status">禁用</el-checkbox>
  </el-checkbox-group>
</template>

<script>
export default {
  data() {
    return {
      status: 1
    };
  }
};
</script>
