Python Selenium 单击悬停按钮

Python Selenium Click On Hover Button

我正在尝试单击按钮来启动文件 下载。根据我所见,该按钮具有悬停功能。我试过点击所有 find_element_by paths.

HTML 页面块,

<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({&quot;source&quot;:&quot;sub_1:listPgFrm:j_idt6461:downloadBtn&quot;,&quot;execute&quot;:'@all',&quot;render&quot;:'@all',&quot;event&quot;:&quot;activate&quot;,&quot;onstart&quot;: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 class 是,

"btn-retrieve ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only"

悬停时按钮的class是,

"btn-retrieve ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only ui-state-hover"

通过开发者选择按钮 window 并从

复制路径
<span>Download</span>==[=14=] 

我得到以下信息,

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()

并且,

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 text-based 定位器:

//button[.='Download']

请检查 dev tools (Google chrome) 我们是否在 HTML DOM 中有 unique 条目。

检查步骤:

Press F12 in Chrome -> 转到 element 部分 -> 执行 CTRL + F -> 然后粘贴 xpath 并查看是否需要 element正在 突出显示 1/1 匹配节点。

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()
