Set operation on key “visible“ failed: target is readonly.

 vue3 报错 Set operation on key "visible" failed: target is readonly.

变量visible只读属性，无法修改。

解决：visible 改成响应式

   // 原先visible 从props.modal获取，
   const { modalData: { visible }} = props

//修改
 const { modalData: { visible }} = props
 const visibleNew = ref(visible)
或
 const { modalData: { visible }} = toRefs(props)
