selenium python中引用js

    def execute_script(self, script, *args):
        """
        Synchronously Executes JavaScript in the current window/frame.

        :Args:
         - script: The JavaScript to execute.
         - \*args: Any applicable arguments for your JavaScript.

        :Usage:
            driver.execute_script('document.title')
        """
        converted_args = list(args)
        return self.execute(Command.EXECUTE_SCRIPT,
            {'script': script, 'args':converted_args})['value']

上面是官方的解释 貌似是可以做到脚本和数据分离来试用,这里我只是简单的用了下  具体的demo如下

        js='var x=document.getElementsByTagName("img");\
        return x[0].getAttribute("src")'
        
        print browser.execute_script(js)
