因为我的B593路由器有时会停留在产生大约50％丢包率的状态下我试图写一个程序让它自动重启，如果让我们说最后100个ping 30丢失了。
我无法点击实际的重启按钮本身，它似乎被一些Javascript加载但是watir无法看到按钮。谷歌搜索相当多，似乎我需要提供这个按钮的路径，我目前正在尝试 - 但到目前为止没有运气。
如果有人能说清楚它会让我和其他一些其他B593的主人成为现实。
这是google检查员在重启按钮上点击“复制XPath”时所说的内容。
//*[@id="btnReboot"]
这是重启按钮在帧源代码中的外观。
<button onclick="reboot()" id="btnReboot">
<script>document.write(gVarReboot);</script>Reboot
</button>

答案 0 :(得分：2)
我找到了另一种方法，但仍然对xpath的方式感兴趣。 ：）
browser.frame(:id => "contentfrm").button(:id => "btnReboot").when_present.click
答案 1 :(得分：1)
另一种方法是直接调用“reboot（）”函数。
以下是：
require "watir"
ie = Watir::IE.new()
ie.goto("address")
ie.execute_script("reboot()")
这直接调用了所需的功能，这样可以省去在页面上找到疯狂事物的麻烦。
祝你好运
