我正试图单击一个按钮来启动文件下载。该按钮具有悬停在我所看到的功能之上。我已尝试通过所有find_element_by paths
进行单击。
页面的HTML块,
<button class="btn-retrieve ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" id="sub_1:listPgFrm:j_idt6461:downloadBtn" name="sub_1:listPgFrm:j_idt6461:downloadBtn" onclick="new ice.ace.DataExporter('sub_1:listPgFrm:j_idt6461:downloadBtn', function() { ice.ace.ab(ice.ace.extendAjaxArgs({"source":"sub_1:listPgFrm:j_idt6461:downloadBtn","execute":'@all',"render":'@all',"event":"activate","onstart":function(cfg){showProcessingMessage('Downloading'); return true;;}}, {node:this})); });return false;" style="margin-top: -4px;" role="button" aria-disabled="false"><span class="ui-button-text"><span>Download</span></span></button>
悬停前按钮的类别是,
"btn-retrieve ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only"
悬停时按钮的类别为,
"btn-retrieve ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only ui-state-hover"
通过开发者窗口选择按钮并从复制路径
<span>Download</span>==$0
我得到以下,
CSS路径,
#sub_1:listPgFrm:j_idt6461:downloadBtn > span > span
XPath、
//*[@id="sub_1:listPgFrm:j_idt6461:downloadBtn"]/span/span
我试过的代码,
dwnd = driver.find_element_by_xpath("//*[@id='sub_1:listPgFrm:j_idt6461:downloadBtn']/span")
dwnd.click()
而且,
button = driver.find_element_by_css_selector("#sub_1:listPgFrm:j_idt6461:downloadBtn")
download = driver.find_element_by_link_text("Download")
hover = ActionChains(driver).move_to_element(button).move_to_element(download)
hover.click().build().perform()
您可以使用基于文本的定位器:
//button[.='Download']
如果我们在HTML DOM
中是否有唯一条目,请检查dev tools
(Google chrome(。
检查步骤:
Press F12 in Chrome
->转到element
部分->进行CTRL + F
->然后粘贴xpath
,看看您想要的element
是否通过1/1
匹配节点突出显示。
你可以点击它:
代码试用1:
time.sleep(5)
driver.find_element(By.XPATH, "//button[.='Download']").click()
代码试用2:
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//button[.='Download']"))).click()
代码试用3:
time.sleep(5)
button = driver.find_element(By.XPATH, "//button[.='Download']")
driver.execute_script("arguments[0].click();", button)
代码试用4:
time.sleep(5)
button = driver.find_element(By.XPATH, "//button[.='Download']")
ActionChains(driver).move_to_element(button).click().perform()
