首先举个例子,html的js弹出窗口的代码如下:
<html>
<head><title>Popup Window</title></head>
<body>
<input id = "btn" value = "click" type = "button" onclick = "alert('hello');"/>
</body>
</html>
当点击按钮会弹出相应的js提示框来,我们一般叫他js弹出窗口。
对于JS的弹出窗口一般常见的有两种,alert/confirm两种,watir-webdriver也有自己的处理方式,我先贴出来:
require "watir-webdriver/extensions/alerts"
JAVASCRIPT ALERTS
browser.alert do
browser.button(:value => 'Alert').click
end #=> 'the alert message'
JAVASCRIPT CONFIRMS
browser.confirm(true) do
browser.button(:value => 'Confirm').click
end #=> 'the confirm message'
JAVASCRIPT PROMPT
browser.prompt('hello') do
browser.button(:value => 'Prompt').click
end #=> { :message => 'foo', :default_value => 'bar' }
不过我用起来,不太方便,我觉得调用底层的selenium-webdriver会比较简单,比方说处理alert的方法
a = b.driver.switch_to.alert
p a.text
a.accept
如果使用Confirm取消用a.dismiss。这样用起来比较简单
还有一种方式就是就是不让窗口弹出来,主要是通过覆盖js原有的方法,具体代码如下,可供参考
# 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}")
