使用selenium反复单击隐藏按钮

Question

我在网页上有几个列表，如下面的示例。第一个列表显示“立即应用”按钮，我可以使用下面的代码单击该按钮。然后在我填充对话框并关闭它后，第一个列表从页面中消失，其他列表仍然可见。但是，在我点击下一个列表中的任何位置之前，“立即申请”按钮不会显示在下一个列表中，然后将弹出“立即应用”按钮以进行列表。此外，如果我刷新页面，则会弹出“立即应用”按钮以进行下一个列表。如果我第二次尝试运行下面的代码，（当下一个列表中看不到“立即应用”按钮时），我将得到以下错误。我的目标是能够为每个列表单击“立即应用”，一个接一个。任何人都可以建议如何在下一个列表中显示“立即应用”按钮，在此示例中为“SecondOne”。我已经尝试了下面的代码，但两次尝试都没有重复。

Answer 1

请尝试以下选项以单击元素。

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[text()[contains(.,'Apply Now')]]"))).click()

要么

WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a.g-button"))).click()

如果以上两个选项没有抛出任何错误，你仍然无法点击，那么试试JavaScripts执行者。

element=WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//a[text()[contains(.,'Apply Now')]]")))
driver.execute_script("arguments[0].click();", element)

让我知道这个是否奏效。
