selenium python，尝试单击按钮

Question

我正在尝试使用以下代码单击“加载更多”按钮

browser.find_element_by_xpath('//*[@id="mainContent"]/div[1]/div/div[5]/div/div[1]').click()
browser.find_element_by_css_selector('#mainContent > div.left-panel > div > div.result-list > div > div.content').click()
browser.find_element_by_link_text('Load More').click()

我收到以下错误：

Traceback (most recent call last):

我已经分别尝试了这 3 个，但似乎无法让硒单击按钮

When pressing inspect that is the following element I receive

元素代码如下：

<div class="content" onclick="javascript:mtvn.btg.Controller.sendLinkEvent({ linkName:'PROFMIDPANE:LoadMore', linkType:'o' } );">Load More</div>

如果有人对我如何实现这一点有任何建议，我将不胜感激！

更新： 我尝试了推荐给我的两种解决方案，但不幸的是没有成功，如果有人感兴趣，我会在这里发布。

iamsankalp89 解决方案：

wait = WebDriverWait(driver, 10)
element = wait.until(EC.element_to_be_clickable((By.XPATH, "//div[@class='content' and text()='Load More']")))
element.click()

朱利安莫雷诺解决方案：

ActionChains(driver).move_to_element("//div[@class='content' and text()='Load More']").click("//div[@class='content' and text()='Load More']").perform()

错误信息：

Answer 1

试试这个 xpath

//div[@class='content' and text()='Load More']

代码是这样的：

browser.find_element_by_xpath('//div[@class='content' and text()='Load More']').click()

也可以使用WebDriverWait

wait = WebDriverWait(driver, 10)
element = wait.until(EC.element_to_be_clickable((By.XPATH, "//div[@class='content' and text()='Load More']")))
element.click()

Answer 2

尝试使用 ActionChains：

类 selenium.webdriver.common.action_chains.ActionChains(driver)

ActionChains(driver).move_to_element(your_element).click(your_element).perform()

移动到元素会将鼠标（光标）移动到元素（your_element）的中间，然后执行函数将执行链接的操作。

编辑

试试这个：

load_more = browser.find_element_by_css_selector("#mainContent > div.left-panel > div > div.result-list > div > div.content")
WebDriverWait(browser, timeout).until(EC.visibility_of(load_more))
browser.execute_script("return arguments[0].scrollIntoView(true);", load_more)
ActionChains(browser).move_to_element(load_more).click().perform()

ActionChains(browser).move_to_element() 接受 WebElement 对象或作为元素 id 的字符串。由于 load more 没有 ID，所以 move_to_element() 找不到 WebElement。

分析网页后，我注意到move_to_element(load_more) 移动到 load_more 按钮（直到它在屏幕内），但它也触发向下滚动并显示网页的页脚。此页脚包含 load_more 按钮。因此，您需要browser.execute_script("return arguments[0].scrollIntoView(true);", load_more)，它基本上会一直滚动，直到 load_more 出现（无论页脚是否显示）。
