# Modal Component

模態元件在對焦的覆蓋視窗中顯示重要資訊或請求使用者操作。模態基於語義 HTML 對話方塊元素構建，支援動畫、可自訂定位和背景覆蓋。 Frutjam 模態系統可透過鍵盤導航和陷阱焦點完全訪問，使其成為確認、表單和警報對話框的理想選擇。

僅 CSS，無需 JavaScript。 WCAG AA 可存取且與框架無關 - 可與 Django、HTMX、Laravel、React 和任何堆疊配合使用。

## 基本用法

將唯一的 ID 新增至

HTML 元素，然後在 JavaScript 中使用該 id 呼叫 `myModal.showModal()` 開啟模式，並使用 `myModal.close()` 關閉模式。

## 按一下外部時關閉模態

`.modal-backdrop` 提供了一個可點擊的背景，當在模態內容之外點擊時，背景會關閉模態。

```html
<dialog class="modal" id="backdropModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Dialog modal</div>
    </div>
    <div class="divider my-3"></div>
    <p class="para">Press Esc key or click outside to close the modal</p>
  </div>
  <button type="button" class="modal-backdrop" onclick="backdropModal.close()">
    Close Modal via Backdrop
  </button>
</dialog>
<button type="button" class="btn btn-xs" onclick="backdropModal.showModal()">Show Modal</button>
```

## 模態幻燈片動畫

使用模態組件中的以下定向實用程式類，從頂部、底部、開始（LTR 中向左、RTL 中向右）或結束（LTR 中向右、RTL 向左）平滑滑入和滑出：`modal-slide-top`、`modal-slide-bottom`、、`modal-slide-bottom`、、`mod-slide-bottom`、<這些動畫透過使用基於模態位置的動態過渡來改善使用者體驗。

### 從頭開始模態幻燈片（水平）

添加 modal-slide-start 實用程式以從起始側水平滑動模態；在從左到右 (LTR) 佈局中，它從左側出現；在從右到左 (RTL) 佈局中，它從右側出現。

```html
<dialog class="modal modal-center lg:modal-middle modal-slide-start" id="slideStartModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Slide start modal</div>
      <button type="button" class="btn btn-xs btn-square btn-rounded btn-ghost" onclick="slideStartModal.close()">
        <svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
          <path d="M18 6 6 18"></path>
          <path d="m6 6 12 12"></path>
        </svg>
      </button>
    </div>
    <div class="divider my-3"></div>
    <p class="para">Horizontally slides the modal in and out from the start side.</p>
  </div>
</dialog>
<button type="button" class="btn btn-xs" onclick="slideStartModal.showModal()">Show Modal</button>
```

### 從末端開始模態滑動（水平）

在模態組件中添加 `modal-slide-end` 實用程序，使模態從末端水平滑動；在從左到右 (LTR) 佈局中，它從右側出現；在從右到左 (RTL) 佈局中，它從左側出現。

```html
<dialog class="modal modal-center lg:modal-middle modal-slide-end" id="slideEndModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Slide end modal</div>
      <button type="button" class="btn btn-xs btn-square btn-rounded btn-ghost" onclick="slideEndModal.close()">
        <svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
          <path d="M18 6 6 18"></path>
          <path d="m6 6 12 12"></path>
        </svg>
      </button>
    </div>
    <div class="divider my-3"></div>
    <p class="para">Horizontally slides the modal in and out from the end side.</p>
  </div>
</dialog>
<button type="button" class="btn btn-xs" onclick="slideEndModal.showModal()">Show Modal</button>
```

### 從底部滑動（垂直）：`modal-slide-up`

方向：從底部垂直滑入

```html
<dialog class="modal modal-center lg:modal-middle modal-slide-up" id="slideUpModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Slide up modal</div>
      <button type="button" class="btn btn-xs btn-square btn-rounded btn-ghost" onclick="slideUpModal.close()">
        <svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
          <path d="M18 6 6 18"></path>
          <path d="m6 6 12 12"></path>
        </svg>
      </button>
    </div>
    <div class="divider my-3"></div>
    <p class="para">Vertically slides the modal in and out from the bottom.</p>
  </div>
</dialog>
<button type="button" class="btn btn-xs" onclick="slideUpModal.showModal()">Show Modal</button>
```

### 從頂部滑動（垂直）

在模態元件中加入 modal-slide-down 公用程式以從頂部垂直滑入。

```html
<dialog class="modal modal-center lg:modal-middle modal-slide-down" id="slideDownModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Slide down modal</div>
      <button type="button" class="btn btn-xs btn-square btn-rounded btn-ghost" onclick="slideDownModal.close()">
        <svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
          <path d="M18 6 6 18"></path>
          <path d="m6 6 12 12"></path>
        </svg>
      </button>
    </div>
    <div class="divider my-3"></div>
    <p class="para">Vertically slides the modal in and out from the top.</p>
  </div>
</dialog>
<button type="button" class="btn btn-xs" onclick="slideDownModal.showModal()">Show Modal</button>
```

### 用於通知的滑動動畫模式的範例用法

```html
<dialog class="modal modal-end modal-top modal-slide-end" id="notificationSlideModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Notification modal</div>
      <button type="button" class="btn btn-xs btn-square btn-rounded btn-ghost" onclick="notificationSlideModal.close()">
        <svg xmlns="http://www.w3.org/2000/svg" width="20" height="20" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round">
          <path d="M18 6 6 18"></path>
          <path d="m6 6 12 12"></path>
        </svg>
      </button>
    </div>
  </div>
</dialog>
<button type="button" class="btn btn-xs" onclick="notificationSlideModal.showModal()">Show Modal</button>
```

## 模態展示位置

預設情況下，模態元件位於螢幕中央，但可以根據使用情況使用水平類別 `modal-start`、`modal-center` 或 `modal-end` 以及垂直類別 `modal-top`、`modal-middle` 或 `modal-bottom`。佈局的設計考慮了 RTL 和 LTR 相容性，使模式能夠適應不同的語言方向和佈局。

使用`modal-start`、`modal-center`或`modal-end`進行水平放置，使用`modal-top`、`modal-middle`或`modal-bottom`進行垂直放置。這些類別應用於模態組件。

### 左上角模態位置

```html
<dialog class="modal modal-start modal-top" id="topLeftModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">

## 桌面和行動螢幕的模態響應式定位

根據您的使用案例，您可以將模態框放置在桌面或行動裝置上的任何位置，例如桌面中心和行動裝置頂部中心。

```html
<dialog class="modal modal-center modal-top lg:modal-center lg:modal-middle" id="responsiveModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Responsive modal</div>
    </div>
    <div class="divider my-3"></div>
    <p class="para">Resize the modal to a small screen to see the change in modal position.</p>
  </div>
  <button type="button" class="modal-backdrop" onclick="responsiveModal.close()">
    Close Modal via Backdrop
  </button>
</dialog>
<button type="button" class="btn btn-xs" onclick="responsiveModal.showModal()">Show Modal</button>
```

## 基於語言方向的模態定位

根據語言方向（LTR 或 RTL）將模態框放置在螢幕上的任意位置。

### LTR 和 RTL 中右對齊且垂直居中

```html
<dialog class="modal ltr:modal-end ltr:modal-middle rtl:modal-start lg:modal-middle" id="ltrModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Responsive modal</div>
    </div>
    <div class="divider my-3"></div>
    <p class="para">
      Changing
      <code>dir="rtl"</code>
      in the HTML will have no effect on the modal's the position because the layout is controlled by utility classes:
      <code>modal-end</code>
      for the LTR variant and
      <code>modal-start</code>
      for the RTL variant.
    </p>
  </div>
  <button type="button" class="modal-backdrop" onclick="ltrModal.close()">
    Close Modal via Backdrop
  </button>
</dialog>
<button type="button" class="btn btn-xs" onclick="ltrModal.showModal()">Show Modal</button>
```

## 根據螢幕尺寸和語言方向放置模態框

```html
<dialog class="modal ltr:modal-center lg:ltr:modal-start ltr:modal-top lg:ltr:modal-middle rtl:modal-center lg:rtl:modal-start rtl:modal-bottom lg:rtl:modal-middle" id="mixedModal">
  <div class="modal-content">
    <div class="flex justify-between items-center gap-3">
      <div class="font-medium heading-lg">Responsive modal</div>
    </div>
    <div class="divider my-3"></div>
    <p class="para">Change the screen and screen direction to see the change in modal position.</p>
  </div>
  <button type="button" class="modal-backdrop" onclick="mixedModal.close()">
    Close Modal via Backdrop
  </button>
</dialog>
<button type="button" class="btn btn-xs" onclick="mixedModal.showModal()">Show Modal</button>
```
