selenium 关于CodeMirror-code中无法输入内

今天在使用 selenium 对CodeMirror-code类型的文本域对象使用send_keys方式输入内容时，发现这种方式不生效了

尝试代码方式：

# 组件内容
b.find_element_by_name("codemirror").send_keys(content)

# 点击保存按钮
b.find_element_by_css_selector("div.componentProgramAddOrEdit-form button.el-button.el-button--primary").click()
time.sleep(0.5)
print("创建[%s]编程组件成功！" % name)

执行后结果报错：

Traceback (most recent call last):
  File "/Users/sleeli/Desktop/programfile/PycharmProjects/testBSC/BCC V3.1/start.py", line 70, in <module>
    createPrograms(b,"组件编程01")

    return self._parent.execute(command, params)

    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.ElementNotInteractableException: Message: element not interactable
  (Session info: chrome=78.0.3904.108)

通过查询.ElementNotInteractableException: Message: element not interactable错误查询发现是因为这个对象是在页面是不可见的，看来不能按正常方法进行输入操作了

最终查询和尝试解决方法如下：
经过查找发现因为默认情况下文本框是display: none;，即使不可见的状态，需要先使用鼠标点击激活后才能进行输入操作

# 找到文本框
# e = b.find_element_by_name("codemirror")  # 第一次通过名称找的文本框找错了 发现还有一个
e = b.find_element_by_css_selector(".CodeMirror textarea") #

# 找到所在输入的行对象
p = b.find_element_by_css_selector("pre.CodeMirror-line")

#对做所在行进行点击操作，激活文本框
p.click()
# 在文本框中输入内容
e.send_keys("Hello, World!")

执行效果，成功输入字符串

说明：

在.CodeMirror下找到的textarea并不是name=codemirror的
