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

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 dblclick ".item-row"
cmux browser surface:2 hover "#menu"
cmux browser surface:2 focus "#email"
cmux browser surface:2 check "#terms"
