我在netbeans中创建了一个程序，程序中的所有选项都有效但是当我把代码粘贴到记事本然后在cmd编译它时，一些选项可以正常工作而有些选项不起作用，为什么会这样？ / p>
let tablesQuery = app.tables
app.navigationBars["LandingScreen"].buttons["Hamburger"].tap()
tablesQuery.staticTexts["alwaysShownButton"].tap()
app.navigationBars["alwaysAccessibleScreen"].buttons["Hamburger"].tap()
tablesQuery.staticTexts["sometimesHiddenButton"].staticTexts.tap() <-fails
以下是其他代码：
