element plus switch组件change事件为什么一开始就会触发？

Question

为什么change事件在一开始就会触发，期间没做啥操作，就接口取了个值

<el-switch
  v-model="scope.row[column.prop]"
  :active-value="1"
  :inactive-value="0"
  @change="parentSwitchChange(scope.row[column.prop], scope.row)"
/>

<script>
const parentSwitchChange = () => {
    console.log(1)
}
</script>
