javascript - Ruby，Watir，无法单击由 Java 脚本加载的框架中的按钮

因为我的 B593 路由器有时会卡在产生大约 50% 数据包丢失的状态，所以我正在尝试编写一个程序让它自动重启，如果让我们说最后 100 次 ping 中有 30 次丢失。

我无法单击实际的重启按钮本身，它似乎是由某些 Javascript 加载的，但 watir 无法看到该按钮。在谷歌上搜索了很多，似乎我需要提供我目前正在尝试做的这个按钮的路径 - 但到目前为止运气不好。

如果有人能说明一些问题，那真的会让我和其他一些 B593 拥有者也很开心。

这是当我点击重启按钮上的“复制 XPath”时 google inspector 所说的内容。

//*[@id="btnReboot"]

这是重启按钮在框架源代码中的样子。

<button onclick="reboot()" id="btnReboot">
<script>document.write(gVarReboot);</script>Reboot
</button>

我当前的代码

require "watir-webdriver"

admin_password = 'stackoverflowcanhelp'

#spawn instance
browser = Watir::Browser.new :chrome

#open homepage
browser.goto "http://192.168.0.75"

#set Langauge to english
browser.select_list(:name => 'Language').select 'English'

#enter password
browser.text_field(:name => "Password").set admin_password

#login
browser.a(:id, "btnLogin").click

#go to reboot menue
browser.cookies.add 'FirstMenu', 'Admin_10', :path => "/"
browser.cookies.add 'SecondMenu', 'Admin_10_1', :path => "/"
browser.cookies.add 'ThirdMenu', 'Admin_10_1_0', :path => "/"

#refresh browser
browser.refresh

#reboot router
browser.button(:xpath, '//*[id="btnReboot"]').click #does not work
browser.alert.set "Click "
browser.alert.ok

#close browser
browser.close

错误信息

gems/watir-webdriver-0.6.2/lib/watir-webdriver/elements/element.rb:490:in `assert_exists': unable to locate element, using {:xpath=>"//*[id=\"btnReboot\"]", :tag_name=>"button"} (Watir::Exception::UnknownObjectException)
    from /Users/stackoverflowfan/.rvm/gems/ruby-1.9.3-p194@rails3tutorial2ndEd/gems/watir-webdriver-0.6.2/lib/watir-webdriver/elements/element.rb:118:in `click'
    from a.rb:29:in `<main>'

最佳答案

我找到了另一种方法，但仍然对 xpath 方法感兴趣。 :)

browser.frame(:id => "contentfrm").button(:id => "btnReboot").when_present.click

关于javascript - Ruby，Watir，无法单击由 Java 脚本加载的框架中的按钮，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16096892/
