selenium send_keys慢，卡，怎么办？这里有你想要的解决方案

相信各位看官在用selenium时，会发现发送长字符时，一个字符一个字符在输入，特别在使用chrome时，更加明显。

如果你的网页是要大量编辑的怎么处理呢？

 

既然问题出来了，我看就先看看send_keys是怎么实现发送字符的，为什么这么慢呢？看看webdriver的源码吧

def send_keys(self, *value):
        """Simulates typing into the element.

        :Args:
            - value - A string for typing, or setting form fields.  For setting
            file inputs, this could be a local file path.

        Use this to send simple key events or to fill out form fields::

            form_textfield = driver.find_element_by_name('username')
            form_textfield.send_keys("admin")

        This can also be used to set file inputs.

        ::

            file_input = driver.find_element_by_name('profilePic')
            file_input.send_keys("path/to/profilepic.gif")
            # Generally it's better to wrap the file path in one of the methods
            # in os.path to return the actual path to support cross OS testing.
            # file_input.send_keys(os.path.abspath("path/to/profilepic.gif"))

        """
        # transfer file to another machine only if remote driver is used
        # the same behaviour as for java binding
        if self.parent._is_remote:
            local_file = self.parent.file_detector.is_local_file(*value)
            if local_file is not None:
                value = self._upload(local_file)

        self._execute(Command.SEND_KEYS_TO_ELEMENT, {'value': keys_to_typing(value)})
