## 指定瀏覽器 surface

大多數子指令需要指定目標 surface。你可以用位置參數或 --surface 來傳遞。

```
# Open a new browser split
cmux browser open https://example.com

# Discover focused IDs and browser metadata
cmux browser identify
cmux browser identify --surface surface:2

# Positional vs flag targeting are equivalent
cmux browser surface:2 url
cmux browser --surface surface:2 url
```

## 導覽

```
cmux browser open https://example.com
cmux browser open-split https://news.ycombinator.com

cmux browser surface:2 navigate https://example.org/docs --snapshot-after
cmux browser surface:2 back
cmux browser surface:2 forward
cmux browser surface:2 reload --snapshot-after
cmux browser surface:2 url

cmux browser surface:2 focus-webview
cmux browser surface:2 is-webview-focused

cmux browser react-grab toggle
cmux browser devtools toggle
cmux browser devtools console
cmux browser focus-mode toggle
cmux browser zoom in
cmux browser zoom reset
cmux browser history clear --force
```

## 等待

使用 wait 來阻塞直到選擇器、文字、URL 片段、載入狀態或 JavaScript 條件滿足。

```
cmux browser surface:2 wait --load-state complete --timeout-ms 15000
cmux browser surface:2 wait --selector "#checkout" --timeout-ms 10000
cmux browser surface:2 wait --text "Order confirmed"
cmux browser surface:2 wait --url-contains "/dashboard"
cmux browser surface:2 wait --function "window.__appReady === true"
```

## DOM 互動

變更操作支援 --snapshot-after，用於腳本中的快速驗證。

```
cmux browser surface:2 click "button[type='submit']" --snapshot-after
cmux browser surface:2 dblclick ".item-row"
cmux browser surface:2 hover "#menu"
cmux browser surface:2 focus "#email"
cmux browser surface:2 check "#terms"
cmux browser surface:2 uncheck "#newsletter"
cmux browser surface:2 scroll-into-view "#pricing"

cmux browser surface:2 type "#search" "cmux"
cmux browser surface:2 fill "#email" --text "ops@example.com"
cmux browser surface:2 fill "#email" --text ""
cmux browser surface:2 press Enter
cmux browser surface:2 keydown Shift
cmux browser surface:2 keyup Shift
cmux browser surface:2 select "#region" "us-east"
cmux browser surface:2 scroll --dy 800 --snapshot-after
cmux browser surface:2 scroll --selector "#log-view" --dx 0 --dy 400
```

## 檢查

腳本使用結構化 getter，人工審查使用快照/截圖。

```
cmux browser surface:2 snapshot --interactive --compact
cmux browser surface:2 snapshot --selector "main" --max-depth 5
cmux browser surface:2 screenshot --out /tmp/cmux-page.png

cmux browser surface:2 get title
cmux browser surface:2 get url
cmux browser surface:2 get text "h1"
cmux browser surface:2 get html "main"
cmux browser surface:2 get value "#email"
cmux browser surface:2 get attr "a.primary" --attr href
cmux browser surface:2 get count ".row"
cmux browser surface:2 get box "#checkout"
cmux browser surface:2 get styles "#total" --property color

cmux browser surface:2 is visible "#checkout"
cmux browser surface:2 is enabled "button[type='submit']"
cmux browser surface:2 is checked "#terms"

cmux browser surface:2 find role button --name "Continue"
cmux browser surface:2 find text "Order confirmed"
cmux browser surface:2 find label "Email"
cmux browser surface:2 find placeholder "Search"
cmux browser surface:2 find alt "Product image"

cmux browser surface:2 find first ".row"
cmux browser surface:2 find last ".row"
cmux browser surface:2 find nth 2 ".row"

cmux browser surface:2 highlight "#checkout"
```

## JavaScript 執行和注入

```
cmux browser surface:2 eval "document.title"
cmux browser surface:2 eval --script "window.location.href"

cmux browser surface:2 addinitscript "window.__cmuxReady = true;"
cmux browser surface:2 addscript "document.querySelector('#name')?.focus()"
cmux browser surface:2 addstyle "#debug-banner { display: none !important; }"
```
