我在通过Selenium Webdriver的PhantomJS API提交表单时遇到了一个奇怪的问题。单击提交按钮后，表单将被验证（用户名和密码太短，或空白等），但最终未提交。也就是说，如果我提交无效表单并检查屏幕截图，则会有警报通知。如果我提交有效表格，则没有任何反应。页面上的JS应该验证表单，然后在单击提交按钮时提交它。
一些规则。我在提交按钮上尝试了.click()和.submit()，这是一个按钮元素。我还在表单本身以及Selenium允许的表单中的任意元素（如密码）上尝试.submit()。
事实上，如果我驾驶Firefox而不是PhantomJS，相同的代码就可以正常运行。不过，我不想切换，因为Firefox速度较慢，而且给我带来了不可预测的连接问题。
我的规格：我在Ubuntu 14.04 LTS（GNU / Linux 3.17.1-elastic x86_64）上通过Python 2.7使用Selenium 1.43版和PhantomJS 1.98。
以下代码。首先是我的Selenium代码。然后是表单的html。然后是来自该站点的login.js源代码。我认为在js中发生的是由于某种原因，invalidHandler函数中的.validate正在运行，但submitHandler不是？提前感谢您的关注。
# enter username and password up here first
submitEl = self.find_element_by_css_selector("button[type='submit']")
submitEl.click()
self.save_screenshot('login_submission.png')
Edit2：＆＃34; self＆＃34;是一个继承自Webdriver.PhantomJS类的驱动程序对象。现在形式为html：

最后ERROR不是我问题的一部分，而是更多的书挡。当抓取算法查找登录后显示的页面上的链接时会发生这种情况。由于我们没有成功提交登录表单，因此该链接自然不存在。
答案 0 :(得分：0)
我不确定哪些更改会导致突破，但我可以说我添加了以下代码。编辑：其中只有两个是新的。删除了一个。
webdriver.DesiredCapabilities.PHANTOMJS["phantomjs.page.settings.localToRemoteUrlAccessEnabled"] = True
webdriver.DesiredCapabilities.PHANTOMJS["phantomjs.page.settings.browserConnectionEnabled"] = True
并且我提交了表单本身，而不是单击一个按钮（在更改上述配置之前我也曾尝试过这个）。
formEl = self.find_element_by_css_selector("form[name='login']")
formEl.submit()
