Python 硒：Send_keys 执行失败
Python Selenium: Send_keys Failed to execute
我想用
填写表格
driver.find_element_by_id("name").send_keys("Test")
但我每次 运行 脚本时都会收到此错误：
Traceback (most recent call last):
File "fill.py", line 22, in <module>

selenium.common.exceptions.WebDriverException: Message: unknown error: Failed to execute 'contains' on 'Node': parameter 1 is not of type 'Node'.

<input first_and_last="true" placeholder="name" class="string required" type="text" name="flname" id="name">
注意：我在搜索名称时也遇到错误。如果我搜索 Xpath，它填写表单的速度非常慢，我需要它更快。
我该如何解决这个问题？
使用任一定位器策略：
css_selector :
driver.find_element_by_css_selector("input.string.required#name").send_keys("Test")
xpath :
driver.find_element_by_xpath("//input[@class='string required' and @id='name']").send_keys("Test")
更新
我已尝试寻找解决您遇到的两条错误消息的方法，以下是相关详细信息：
selenium.common.exceptions.WebDriverException: Message: unknown error: Failed to execute 'contains' on 'Node': parameter 1 is not of type 'Node'. ：根据讨论 possibly your application is based on Polymer and before you start looking out for any element soon after Page Load as a precautionary measure induce a waiter through WebDriverWait along with proper expected_conditions
Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element'." ：根据讨论 JS: Failed to execute 'getComputedStyle' on 'Window': parameter is not of type 'Element' and Failed to execute 'getComputedStyle' on 'Window': parameter 1 is not of type 'Element' error 指出了类似的行为，即所需元素实际上并不存在于 DOM 而 JavaScript 或 Ajax 调用 正在处理 adding/removing 个元素。
