删除警报确认与watir webdriver的JavaScript

watir webdriver和javascript对话框我有例子，不能摆脱测试中的警报。这是JavaScript的删除警报确认与watir webdriver的JavaScript

<script> 
alert("hello.\n\nPress OK to go."); 
</script>

然后我需要点击它，网页会加载

require 'watir-webdriver' 
require 'webdriver-user-agent' 
b = Watir::Browser.new Webdriver::UserAgent.driver(:browser => :chrome, :agent => phone.to_sym, :orientation => :landscape) 
b.goto "file:///test.html"

误差

    from test.rb:7:in `each' 
    from test.rb:7:in `<main>'

与

b.execute_script "window.onbeforeunload = null"

这个工作正常如果JavaScript是d ifhere如window.onbeforeunload

但这个警报给我错误，所有后来的工作不再工作，因为我不能点击该警报，以便页面加载。

# don't return anything for alert 
browser.execute_script("window.alert = function() {}") 

# return some string for prompt to simulate user entering it 
browser.execute_script("window.prompt = function() {return 'my name'}") 

# return null for prompt to simulate clicking Cancel 
browser.execute_script("window.prompt = function() {return null}") 

# return true for confirm to simulate clicking OK 
browser.execute_script("window.confirm = function() {return true}") 

# return false for confirm to simulate clicking Cancel 
browser.execute_script("window.confirm = function() {return false}") 

# don't return anything for leave page popup 
browser.execute_script("window.onbeforeunload = null")

但它不工作，因为页面不加载和警报之前，我无法找到点击它的方式。

这似乎有点哈克，但以下似乎工作。

require 'watir-webdriver' 
require 'webdriver-user-agent' 

driver = Webdriver::UserAgent.driver(:browser => :chrome, :agent => phone.to_sym, :orientation => :landscape) 
b = Watir::Browser.new driver 

begin 
    b.goto "file:///test.html" 
rescue Selenium::WebDriver::Error::UnhandledAlertError 
    b.alert.ok 
end 

# Continue to use the page

基本上，你：

转到页
救援异常
使用的Watir的警报API在警报
点击好继续自己的方式
