JavaScript 警告框,提示框和确认框
WebDriver提供了一个API, 用于处理JavaScript提供的三种类型的原生弹窗消息. 这些弹窗由浏览器提供限定的样式.
Alerts 警告框
其中最基本的称为警告框, 它显示一条自定义消息, 以及一个用于关闭该警告的按钮, 在大多数浏览器中标记为"确定"(OK). 在大多数浏览器中, 也可以通过按"关闭"(close)按钮将其关闭, 但这始终与“确定”按钮具有相同的作用. 查看样例警告框.
WebDriver可以从弹窗获取文本并接受或关闭这些警告.

Prompt 提示框
提示框与确认框相似, 不同之处在于它们还包括文本输入. 与处理表单元素类似, 您可以使用WebDriver的sendKeys来填写响应. 这将完全替换占位符文本. 按下取消按钮将不会提交任何文本. 查看样例提示框.
