使用 Tailwind UI 所提供 button。

第 6 行

Modal dialog 會使用 v-if 顯示，搭配 Vue 的 <transition> 使其逐漸變化。

15 行

<div v-if="isShowModal" class="fixed z-10 inset-0 overflow-y-auto" aria-labelledby="modal-title" role="dialog" aria-modal="true">

使用 isShowModal state 控制 modal dialog 是否顯示。

61 行

ref: isShowModal = false

定義 isShowModal state 且初始值為 false。

63 行

let onShow = () => isShowModal = true

當 Submit 按下時執行 onShow()，將 isShowModal 設定為 true 顯示 modal dialog。

64 行

let onHide = () => isShowModal = false

當 modal dialog 的 Cancel、Deactivate 與 Dimiss 按下時執行 onHide()，將 isShowModal 設定為 false 隱藏 modal dialog。

功能不變，但使用 Point-free 改寫。

<script setup>
import { ref } from 'vue'
import { write } from 'vue3-fp'
import { pipe, always } from 'ramda'

let isShowModal = ref(false)

let onShow = pipe(
  always(true),
  write(isShowModal)
)

let onHide = pipe(
  always(false),
  write(isShowModal)
)
</script>

65 行

let isShowModal = ref(false)

使用 ref() 定義 isShowModal state 方便 Function Pipeline。

67 行

let onShow = pipe(
  always(true),
  write(isShowModal)
)

組合出 onShow()：

always()：準備 true
write()：寫入 isShowModal state

72 行

let onHide = pipe(
  always(false),
  write(isShowModal)
)

組合出 onHide()：

always()：準備 true
write()：寫入 isShowModal state

Conclusion

Tailwind UI 已經提供 modal dialog，我們只要小心控制其 state 就可使用
