看着是readyonly,尝试js移除readonly属性，然后直接send_keys

# 输入元素 下拉框方法封装 #直接sendkeys不行，不会往下走
def base_send_keys(self, loc, value):
    # 先找到元素
    el = self.base_find(loc)
    self.driver.execute_script("document.getElementsByTagName(‘input‘)[0].removeAttribute(‘readonly‘);")
    self.driver.execute_script("document.getElementsByTagName(‘input‘)[1].removeAttribute(‘readonly‘);")
    # 输入
    el.send_keys(value)
send是send进去了，但是带不出来下一个NOSTRO CODE的值，要点击一下才能触发去带出来对应的值

好换一种：
# 选择下拉元素方法封装 
def base_select(self, loc,value):
    Select(self.driver.find_element_by_xpath(loc)).select_by_visible_text(value)

#Message: Select only works on <select> elements, not on <li>
确实不是个正经的下拉框

正常还可以用actionchain，不过也失败了，代码被我改过了，不粘了

最后写了个demo

def test_demo(self):
    options = Options()
    options.add_experimental_option ("debuggerAddress", "127.0.0.1:9222")
    self.driver = webdriver.Chrome(options = options)
    _iframe_loc = self.driver.find_elements(By.CSS_SELECTOR,‘.iframe‘)#//*[@id="pane-#CBIBANK"]/iframe
    self.driver.switch_to.frame(_iframe_loc[1])
    self.driver.find_element_by_xpath("//*[@class=‘el-input__inner‘]").click()
    # els = self.driver.find_elements_by_xpath(‘//li[@class="el-select-dropdown__item"]‘)
    # for el in els:
    #     # print(el.get_attribute("outerText"))
    #     if "SIGNATURE BANK" in el.text:
    #         el.click()
    el = self.driver.find_element_by_xpath(‘//li[@class="el-select-dropdown__item"]/span[contains(text(),"SIGNATURE BANK")]‘)
    print(el)
    self.driver.execute_script("arguments[0].click();",el)
    # # print(els)

发现先找到元素，然后用js点击是可行的

#下拉框找到元素，js,click
def base_js_click(self,el):
    self.driver.execute_script("arguments[0].click();",el)

填坑webUI自动化-下拉选择元素
