Selenium元素不会点击

Question

我有一个问题，其中.click()不适用于元素。一旦用鼠标点击它弹出一个小窗口，可以选择的值。不过，我不能让硒单击该元素，因为它会给我错误，即使找到元素。使用Selenium IDE并记录我的动作，它会在同一个元素上记录点击动作，所以我不明白什么是不工作的。到目前为止，我浏览并点击了很多元素。

以下是代码片段，引发错误：

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 
from selenium.webdriver.support.ui import Select 
import time 

def FirefoxTest(): 
    fp = webdriver.FirefoxProfile('C:/Users/MYUSER/AppData/Roaming/Mozilla/Firefox/Profiles/ethy92lt.default') 
    driver = webdriver.Firefox(fp) 
    site = ("www.company_intranet.com") 
    driver.get(site) 
    try: 
     WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, "C29_W35_V37_V46_btresporg_struct.partner_no-btn"))) 
    except: 
     print("C29_W35_V37_V46_btresporg_struct.partner_no-btn not found") 
    driver.find_element_by_id("C29_W35_V37_V46_btresporg_struct.partner_no-btn").click() 

元素的ID我尝试点击：

<a class="th-ip-h" id="C29_W35_V37_V46_btresporg_struct.partner_no-btn" href="javascript:void(0)" onclick="thtmlb_hideContextMenu(event); thtmlbCSVHManger.inputfieldF4IconClick('C29_W35_V37_V46_btresporg_struct.partner_no','C29_W35_V37_V46','ZSRQM_PROB_H','PROBLEMHEADEREF');htmlbSubmitLib('htmlb',this,'thtmlb:inputField:inputField:null','myFormId','C29_W35_V37_V46_btresporg_struct.partner_no','\x23AUTONAV\x23OP_FINDRESPORG\x23BTRESPORG\x230\x23PARTNER_NO',0);return false;" onfocus="thtmlbSaveKeyboardFocus('C29_W35_V37_V46_btresporg_struct.partner_no');thtmlb_hideContextMenu();" title="Open Input Help"><img class="th-ip-img" src="/SAP/BC/BSP/SAP/ZIR_STYLES/EHP3 default/images/helpF4.gif" alt="Open Input Help"></a> 

错误，我得到：

编辑：睡眠计时器之前已经解决了问题

time.sleep(5) driver.find_element_by_id("C29_W35_V37_V46_btresporg_struct.partner_no-btn").click()

有你一个问题tryexcept块，你等元素，但即使超时你仍会尝试找到它。它应该如下：

try: 
    WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, "C29_W35_V37_V46_btresporg_struct.partner_no-btn"))) 
    driver.find_element_by_id("C29_W35_V37_V46_btresporg_struct.partner_no-btn").click() 
except TimeoutException: 
    print("C29_W35_V37_V46_btresporg_struct.partner_no-btn not found") 

虽然我不认为这是问题的根源。
