无法使用硒触发对某个链接的点击 [英] Can't trigger a click on a certain link using selenium

问题描述

我用python用selenium编写了一个脚本，单击网页上的某个链接以下载Excel文件.但是，当我执行脚本时，它会抛出timeout异常.我该如何运作?任何帮助将不胜感激.

I've written a script in python with selenium to click on a certain link in a webpage to download an excel file. However, when I execute my script, it throws timeout exception. How can I make it work? Any help will be greatly appreciated.

我尝试过的脚本:

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.Chrome()
wait = WebDriverWait(driver, 10)
driver.get('replace_with_above_link')

item = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, ".hasmore #dlink")))
item.click()
driver.quit()

包含下拉选项的HTML元素:

Html elements which contain the dropdown options:

<li class="hasmore drophover"><span>Share &amp; more</span><div><ul><li><button class="tooltip" tip="Use a customizable report creator that can<br>output HTML, CSV, or a shareable link." id="share_on_ajax_result_table">Modify &amp; Share Table</button></li><li><button class="tooltip" tip="Get a bit of widget code to emed this table on your site">Embed this Table</button></li><li><button class="tooltip" tip="Convert the table below to comma-separated values<br>suitable for use with excel">Get as Excel Workbook (experimental)</button><a id="dlink" style="display: none;"></a></li><li><button class="tooltip" tip="Export table as <br>suitable for use with excel">Get table as CSV (for Excel)</button></li><li><button class="tooltip" tip="">Strip Mobile Formatting</button></li><li><a id="a_ajax_result_table" name="ajax_result_table" href="#ajax_result_table::none">Copy Link to Table to Clipboard</a></li><li><button class="tooltip" tip="">About Sharing Tools</button></li><li><button class="tooltip" tip=""><a href="https://www.youtube.com/watch?v=MWapXbaWs_U&amp;feature=youtu.be" target="_blank">Video: SR Sharing Tools &amp; How-to</a></button></li><li><button class="tooltip" tip=""><a href="https://www.youtube.com/watch?v=JkDLV0roT14&amp;feature=youtu.be" target="_blank">Video: Stats Table Tips &amp; Tricks</a></button></li></ul></div></li>

该文件在该网页中的位置(所需的链接用铅笔标记):

Location of that file in that webpage (the desired link is marked with pencil):

推荐答案

目标链接已隐藏，因此等待其可见性将始终失败.您应该尝试处理button节点:

Target link is hidden and so wait for its visibility will always fail. You should try to handle button node instead:

item = wait.until(EC.visibility_of_element_located((By.XPATH, "//li[span='Share & more']")))
item.click()
wait.until(lambda driver: "drophover" in item.get_attribute("class"))
item.find_element_by_xpath("//button[.='Get as Excel Workbook (experimental)']").click()
