如何使用selenium python单击链接

Question

我尝试使用selenium在jsp网页中打开html链接，但它返回错误“无法定位元素”。请帮我解决这个问题，提前谢谢

HTML:

 <a href="#" class="dashboard-stat dashboard-stat-v2 blue" id="bookedOrders">
 </a>

Python代码：

_user = browser.find_element_by_name('username')
_user.send_keys(user_name)

_pass = browser.find_element_by_name('password')
_pass.send_keys(password)

submit = browser.find_element_by_id('submit-form')
submit.click()

order = browser.find_element_by_id('bookedOrders')
order.click()

错误：

Traceback (most recent call last):
  File "main.py", line 23, in <module>
    order = browser.find_element_by_id('bookedOrders')

您要等待元素。一种方法如下所示：

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

_user = browser.find_element_by_name('username')
_user.send_keys(user_name)

_pass = browser.find_element_by_name('password')
_pass.send_keys(password)

submit = browser.find_element_by_id('submit-form')
submit.click()

order = WebDriverWait(driver, 10).until(
    EC.element_to_be_clickable((By.ID, "bookedOrders")))
order.click()

#order = browser.find_element_by_id('bookedOrders')
#order.click()
