本文介绍了使用Selenium Webdriver上传文件并使用<按钮类型=“按钮”>的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用Selenium WebDriver和Ruby，我需要自动化文件上传功能。
我试过了
WAIT.until {driver.find_element（：css，'div.ui-dialog-buttonset'）。显示？ }
通过使用它可以让超时错误
elem = driver.find_element（：css，'div.ui-dialog-buttonset'）
putsHi
js =<< -end
var buttons = document.querySelectorAll（'button'）;
buttons [0] .setAttribute（'aria-disabled'，true）;
end
elem = driver.execute_script（js，elem）
puts elem
elem.send_keys（C：\\ Users \\\\\\\\\\\\' Desktop \\1413.jpg）
以上代码无法正常工作，脚本因错误
这里是HTML代码
< div class =ui -dialog-buttonpane ui-widget-content ui-helper-clearfix>
< div class =ui-dialog-buttonset>
< button class =otherButtonClass ui-state-hover ui-state-focustype =buttonrole =buttonaria-disabled =false>
< button class =otherButtonClasstype =buttonrole =buttonaria-disabled =falsestyle =display：none;>
< button class =cancelButtonClasstype =buttonrole =buttonaria-disabled =false>
< / div>
< / div>
这里是错误堆栈

善意帮助
解决方案
首先检查链接以避免这种超时错误。
您可以尝试下面的代码：
＃隐式超时声明
wait = Selenium :: WebDriver :: Wait.new（：timeout => 60）
＃等待显示所需的按钮元素
＃使用链接：http://www.w3schools.com/cssref/css_selectors.asp
＃for css选择器
wait.until {driver.find_element（：css，'div.ui-dialog-buttonse>按钮'）[1] .displayed？ }
elem = driver.find_element（：css，'div.ui-dialog-buttonse> button'）[1]
elem.sendKeys（C：//path/To/File.jpg ）
更新
查看链接和您的零件 html 下方，我看到 aria-disabled 设置为 false ：
< button class =otherButtonClass ui-state-hover ui-state-focustype =buttonrole =buttonaria-disabled =false>
所需的按钮元素已禁用。
现在看到以下问题： $ b
更新
#implicit超时声明
wait = Selenium :: WebDriver :: Wait.new（：timeout => 60）
＃等待显示div元素
wait.until {driver.find_element（：css，'div.ui-dialog-buttonse'）。显示？ }
elem = driver.find_element（：css，'div.ui-dialog-buttonse'）
js =<<< -end
var buttons = document.querySelectorAll （ '按钮'）;
buttons [0] .setAttribute（'aria-disabled'，true）;
end
elem = driver.execute_script（js，elem）
elem.sendKeys（C：//path//To//File.jpg）
I am using Selenium WebDriver and Ruby and I need to automate the file upload feature.I tried with
WAIT.until { driver.find_element(:css,'div.ui-dialog-buttonset').displayed? }
by using this it gives time out error
elem = driver.find_element(:css,'div.ui-dialog-buttonset')
puts "Hi"
js = <<-end
var buttons = document.querySelectorAll('button');
buttons[0].setAttribute('aria-disabled', true);
end
elem = driver.execute_script(js, elem)
puts elem
elem.send_keys("C:\\Users\\seema\\Desktop\\1413.jpg")
Above code is not working and script fails by following error
here is HTML code
<div class="ui-dialog-buttonpane ui-widget-content ui-helper-clearfix">
<div class="ui-dialog-buttonset">
<button class="otherButtonClass ui-state-hover ui-state-focus" type="button" role="button" aria-disabled="false">
<button class="otherButtonClass" type="button" role="button" aria-disabled="false" style="display: none;">
<button class="cancelButtonClass" type="button" role="button" aria-disabled="false">
</div>
</div>

解决方案
First check out the link Selenium::WebDriver::Wait to avoid such time out error.
You can try the below code :
# implicit time out declarations
wait = Selenium::WebDriver::Wait.new(:timeout => 60)
# wait till the required button element being displayed
# Use the link : http://www.w3schools.com/cssref/css_selectors.asp
# for css selectors
wait.until { driver.find_element(:css,'div.ui-dialog-buttonse>button')[1].displayed? }
elem = driver.find_element(:css,'div.ui-dialog-buttonse>button')[1]
elem.sendKeys("C://path/To/File.jpg")
Update
Looking at the link aria-disabled attribute and your part html below, I am seeing aria-disabled is set as false :
<button class="otherButtonClass ui-state-hover ui-state-focus" type="button" role="button" aria-disabled="false">
That desired button element is disabled.
Now see the question : Does WebDriver support file uploads?
Update
#implicit time out declarations
wait = Selenium::WebDriver::Wait.new(:timeout => 60)
#wait till the div element is being displayed
wait.until { driver.find_element(:css,'div.ui-dialog-buttonse').displayed? }
elem = driver.find_element(:css,'div.ui-dialog-buttonse')
js = <<-end
var buttons = document.querySelectorAll('button');
buttons[0].setAttribute('aria-disabled', true);
end
elem = driver.execute_script(js, elem)
elem.sendKeys("C://path//To//File.jpg")
