我有这个功能来使用硒填充 webfroms

def fill_form(self, action, dict):
        import time
        print "Starting %s ... \n" % action

        # fill the form
        for key in dict.keys():
            try:
                inputElement = self._driver.find_element_by_name(key)
                inputElement.clear()
                inputElement.send_keys(dict[key])
                time.sleep(0.5)
            except:
                self.log()
                pass

当然这个函数是类的一部分

使用此功能硒忽略任何下拉菜单，因此我必须填充每个下拉菜单，然后始终使用正常语句但在循环之前，例如：

inputElement = driver.find_element_by_name('dropdownMenu')
inputElement.send_keys('Test')
object.fill_form('action here', dict)

我尝试使用没有该功能的循环，但它给出了相同的结果，问题是循环！

我在日志文件中也有很多异常
