页面更改时的NoSuchElementException

Question

代码一直工作到curPage=12，并在curPage=13中停止并显示上面的错误。我尝试了By.XPATH &By.css-选择器，但它不起作用。此外，也没有定位元素的框架。

相同的XPath &CSS-选择器，但在页面更改后不工作。

如果有人有主意，请救救我。

结果发现，每个xpath都有自己的元素“onclick”。因此，我更改了xpath，如下所示，它可以工作！

onClick='fn_page_link({}); return false;'.format(curPage)
driver.find_element(By.XPATH, '//a[contains(@onclick, onClick)]').click()
