检查元素在硒中是否可点击 [英] Check whether element is clickable in selenium

问题描述

我可以验证元素是否存在以及是否显示，但似乎无法找到一种方法来查看它是否是可点击的（不是说禁用）。

问题在于，当填充webform时，我想要的元素可能会在加载时用div覆盖。 div本身很难被发现，因为它是id，名字，甚至css都很灵活。因此，我试图检测是否可以点击或填充输入字段。当覆盖div存在时，该字段不能由普通用户填充（因为div将覆盖输入字段并且不允许用户填充它），但它可以由硒填充。我想阻止这种情况，只有在用户也可以填充硒时才允许硒填充它。

  from selenium import webdriver 
 from selenium.webdriver.common.by import By 
 from selenium.webdriver.support.ui从selenium.webdriver.support导入WebDriverWait 
导入expected_conditions作为EC 
 
驱动程序= webdriver.Firefox（）
 driver.get（http：/ / somedomain）
 
 element = WebDriverWait（driver，10）.until（
 EC.element_to_be_clickable（（By.ID，myDynamicElement））
）

或者，您可以按照 EAFP 原则并捕获异常为r alen by click（）：

  from selenium.common.exceptions import WebDriverException 
 
尝试：
 element.click（）
除WebDriverException外：
 print元素不可点击
  

I'm able to verify whether or not an element exists and whether or not it is displayed, but can't seem to find a way to see whether it is 'clickable' (Not talking about disabled).

Problem is that often when filling a webform, the element i want may be overlayed with a div while it loads. The div itself is rather hard to detect as it's id, name and even the css is flexible. Hence i'm trying to detect whether or not a input field can be 'clicked' or 'filled'. When the overlaying div is present, the field cannot be filled by a regular user (As the div would overlay the input field and not allow the user to fill it) but it can be filled by selenium. I want to prevent that and only allow selenium to fill it once the user can also fill it.

解决方案

You can wait for the element to be clickable:

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

driver = webdriver.Firefox()
driver.get("http://somedomain")

element = WebDriverWait(driver, 10).until(
    EC.element_to_be_clickable((By.ID, "myDynamicElement"))
)

---

Or, you can follow the EAFP principle and catch an exception being raised by click():

from selenium.common.exceptions import WebDriverException

try:
    element.click()
except WebDriverException:
    print "Element is not clickable"
