測試需求：如下圖所示，要求根據裝置使用人條件去自動勾選頁面左側的勾選框

首先獲取到該頁裝置使用人和勾選框的元素列表，通過遍歷裝置使用人元素列表獲取裝置使用人文字，判斷名字，假如text="yanfukun",序號num加入到列表list中。再遍歷列表list,通過選擇框元素索引去勾選選擇框，即可完成上面需求，注意索引取值減一。

程式碼如下：

for x in range(1,7):
        ms = driver.find_element_by_xpath('//iframe[2]')
        driver.switch_to.frame(ms)
        time.sleep(1)
        driver.find_element_by_xpath('//div/a[contains(@onclick,"新增列印裝置")]').click()
        driver.switch_to.default_content()
        time.sleep(1)
        ms1 = driver.find_element_by_xpath('//div[@class="layui-layer-content"]/iframe')
        driver.switch_to.frame(ms1)
        
        driver.find_element_by_xpath('//div[@class="col-sm-7"]/input[@name="device_address"]').clear()
        driver.find_element_by_xpath('//div[@class="col-sm-7"]/input[@name="device_address"]').send_keys('localhost')
        driver.find_element_by_xpath('//div/input[@name="device_port"]').clear()
        driver.find_element_by_xpath('//div/input[@name="device_port"]').send_keys('8000')
        time.sleep(1)
        Select(driver.find_element_by_xpath('//div/select[@name="device_name"]')).select_by_value('Fax')
        time.sleep(1)
        Select(driver.find_element_by_xpath('//select[@name="print_format" and @required]')).select_by_value(str(x))
        driver.find_element_by_xpath('//div[@class="col-sm-7"]/input[@name="printer_name"]').clear()
        driver.find_element_by_xpath('//div[@class="col-sm-7"]/input[@name="printer_name"]').send_keys('yanfukun')
        driver.find_element_by_xpath('//div[@class="col-sm-4 col-sm-offset-5"]/button').click()
        driver.switch_to.default_content()
        time.sleep(4)
        
    ms2 = driver.find_element_by_xpath('//iframe[2]')
    driver.switch_to.frame(ms2)
    # ----------------核心邏輯程式碼------------------
    elements_1 = driver.find_elements_by_xpath('//tbody[1]/tr/td[5]')
    elements_2 = driver.find_elements_by_xpath('//td/input[@type="checkbox"]')
    #print(elements_2)
    list = []
    num = 1
    
    for x in elements_1:
        text1 = x.text
        #print(text1)
        if text1 == "yanfukun":
            list.append(num)
            num = num + 1
        else:
            num = num + 1
    print(list)
    for y in list:
        #print(y)
        elements_2[y-1].click()
        time.sleep(0.5)
    # ----------------核心邏輯程式碼------------------
    driver.find_element_by_xpath('//div/a[@onclick="printerObject.delContainerSelect()"]').click()
    driver.switch_to.default_content()
    driver.find_element_by_xpath('//div/a[@class="layui-layer-btn0"]').click()
