关于webdriver定位元素，报错无法点击

1.换ENTER键
from selenium.webdriver.common.keys import Keys

imageTypeRadio = '//i[starts-with(@class,"input-helper") and contains(.,"%s")]'% image_type
context.driver.find_element_by_xpath(imageTypeRadio).send_keys(Keys.ENTER)

2.元素在页面下方，被遮挡，聚焦到元素后再点击
ERROR Message: unknown error: Element <label>...</label> is not clickable at point (597, 835). Other element would receive the click: <div data-v-d25eeca0="" class="button-box" style="top: 777px;">...</div>

解决方法：聚焦滚动到元素可见，再点击

target = driver.find_element_by_id("id_keypair")
driver.execute_script("arguments[0].scrollIntoView();", target) #拖动到可见的元素去

3.元素被透明遮罩层遮挡，等待遮罩层消失
ERROR Message: unknown error: Element <button class="k-btn" tabindex="0" type="button">...</button> is not clickable at point (811, 352). Other element would receive the click: <div class="ksc-loading-mask"></div>

解决方法：

from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

def wait_loading(context):
    try:
        WebDriverWait(context.driver, 1, 0.1).until(
            EC.visibility_of_element_located((By.XPATH, "//div[@class='ksc-loading-mask']")))
    except TimeoutException:
        pass
    WebDriverWait(context.driver, SMALL_TIME_OUT).until(
        EC.invisibility_of_element_located((By.XPATH, "//div[@class='ksc-loading-mask']")))
