任何人都知道如何点击该按钮而不会出错?

Anyone have any ideas as to how to click that button without errors?

推荐答案

此错误信息...

selenium.common.exceptions.NoSuchElementException: Message: no such element: Unable to locate element: {"method":"name","selector":"submitNext"}
  (Session info: chrome=66.0.3359.170)
  (Driver info: chromedriver=2.36.540470)

...表示 ChromeDriver 无法找到所需的元素.

...implies that the ChromeDriver was unable to locate the desired element.

根据您分享的 HTML，点击元素，您可以使用以下任一定位器策略:

As per the HTML you have shared to click on the element you can use either of the following Locator Strategies :

• css_selector :

driver.find_element_by_css_selector("input[name='submitNext'][value='Next']").click()

xpath :

driver.find_element_by_xpath("//input[@name='submitNext' and @value='Next']").click()

但是，您的主要问题是您使用的二进制文件之间的版本兼容性，如下所示:

However your main issue is the version compatibility between the binaries you are using as follows :

• 您正在使用 chromedriver=2.36
• chromedriver=2.36 的发行说明明确提到以下内容:

支持 Chrome v63-65

• 您正在使用 chrome=66.0
• ChromeDriver v2.38的发行说明 明确提及以下内容:

支持 Chrome v65-67

• 我们不知道您的 Selenium Client 版本.

因此 ChromeDriver v2.36 和 Chrome 浏览器 v66.0 之间存在明显的不匹配

So there is a clear mismatch between the ChromeDriver v2.36 and the Chrome Browser v66.0

• 将 Selenium 升级到当前级别版本 3.11.0.
• 将 ChromeDriver 升级到当前的 ChromeDriverv2.38 级别.
• 将 Chrome 版本保持在 Chrome v66.x 级别.(根据 ChromeDriver v2.38 发行说明)
• 清理您的项目工作区，通过您的 IDE 并重建您的项目，仅使用所需的依赖项.
• 使用 CCleaner 工具清除所有操作系统杂事在执行测试套件之后.
• 如果您的基本Web Client 版本太旧，请通过卸载它Revo Uninstaller 并安装 Web Client 的最新 GA 和发布版本.
• 进行系统重启.
• 执行您的@Test.
• Upgrade Selenium to current levels Version 3.11.0.
• Upgrade ChromeDriver to current ChromeDriver v2.38 level.
• Keep Chrome version at Chrome v66.x levels. (as per ChromeDriver v2.38 release notes)
• Clean your Project Workspace through your IDE and Rebuild your project with required dependencies only.
• Use CCleaner tool to wipe off all the OS chores before and after the execution of your test Suite.
• If your base Web Client version is too old, then uninstall it through Revo Uninstaller and install a recent GA and released version of Web Client.
• Take a System Reboot.
• Execute your @Test.
