找到WebDriver元素，但单击不返回任何内容
我找不到现有post的解决方案（虽然我一直在寻找）。 我在下拉菜单中进行选择后尝试从代码中的URL中抓取数据。 最后，我想点击“保存”按钮并下载excel文件。 这是可以正常工作的代码，但最终没有点击保存按钮。
from selenium import webdriver from selenium.webdriver.support.ui import Select from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.common.by import By from selenium.webdriver.support import expected_conditions as EC from selenium.common.exceptions import NoSuchElementException url = 'http://omms.nic.in/#' browser = webdriver.Chrome() browser.get(url) 单击菜单中的“进度监控”项，然后单击“物理和财务项目摘要”项。 然后我为每个下拉项目做出选择。
progElem = browser.find_element_by_link_text('Progress Monitoring').click() summElem = browser.find_element_by_link_text("Physical and Financial Project Summary").click() browser.implicitly_wait(10) #select the state stateElem = browser.find_element_by_xpath("//select[@name='StateCode']") state_select = Select(stateElem) ap = state_select.select_by_visible_text('Andhra Pradesh') #select the district distElem = browser.find_element_by_xpath("//select[@name='DistrictCode']") dist_select = Select(distElem) dist = dist_select.select_by_visible_text('All Districts') #select the block blockElem = browser.find_element_by_xpath("//select[@name='BlockCode']") block_select = Select(blockElem) block = block_select.select_by_visible_text('All Blocks') #select the year yearElem = browser.find_element_by_xpath("//select[@name='Year']") year_select = Select(yearElem) year = year_select.select_by_visible_text('2016-2017') #select the batch batchElem = browser.find_element_by_xpath("//select[@name='Batch']") batch_select = Select(batchElem) batch = batch_select.select_by_visible_text('All Batches') #select the funding agency collabElem = browser.find_element_by_xpath("//select[@name='FundingAgency']") collab_select = Select(collabElem) collab = collab_select.select_by_visible_text('Regular PMGSY') # check the roadwise box checkElem = browser.find_element_by_xpath("//input[@name='RoadWise']") browser.execute_script("arguments[0].click();", checkElem) # click on the view button viewElem = browser.find_element_by_xpath("//input[@type='button']") viewElem.click() #switch to a new frame browser.switch_to_frame(browser.find_element_by_xpath("//iframe")) WebDriverWait(browser, 40).until( EC.element_to_be_clickable((By.XPATH,"//table[@title='Export drop down menu']"))) saveElem = browser.find_element_by_xpath("//table[@title='Export drop down menu']") saveElem.click() #excelElem = browser.find_element_by_xpath("//a[@title='Excel']") #excelElem.click() #browser.execute_script("arguments[0].click();", excelElem)
代码成功运行，但是没有单击“保存”按钮。 令人惊讶的是，一旦我在我的spyder编辑器中运行代码。 然后在IPython shell中键入saveElem.click（），单击该按钮。
我太初学了解正在发生的事情。
这是工作代码：
