如何使用Selenium和python将字符序列发送到contenteditable =“ true”元素

Question

lately, I try to use python3.6 and selenium to do a small task, I want to log in a chatting webpage and send the message automatically.

http://maimai.cn/?regfr=baidu_pc_title this is the webpage that I want to send the message to

In my limited experience with python, I only know that the input element can send string. However, I came across this tough question.
I google a lot and I know that I need to use JavaScript in my python code to insert the string into a div element whose attribute contenteditable is true. when I run my code like this:

my_desired_text="lzylzylzy" driver.execute_script("document.getElementsByClassName('inputPanel'[0].innerHTML="+ my_desired_text)

it warns me like that:

selenium.common.exceptions.WebDriverException: Message: unknown error: lzylzylzy is not defined

but I indeed define my string. I am searching for a long time on the net. But no use, please help or try to give some ideas on how to achieve this. Thanks in advance.

在我的项目中，首先要放置一个iframe元素。我在iframe中找到了一个元素，但是我忘了切换到主框架。这个元素在主框架中，这就是为什么我找不到它的原因。如果遇到类似情况，则可以检查是否切换到主机并使用.sendkey（）方法发送字符串。
