我无法在引导日期选择器中找到日期，月份和年份。当我尝试检查日历中的元素时，日历将关闭并且无法找到该元素。
答案 0 :(得分：0)
打开页面，单击负责显示日历的控件并调用WebDriver.getPageSource()函数，应该没问题。
示例代码（由于WebDriverWait调用的异步特性，它使用DOM来确保日历小部件在那里，因为AJAX准备就绪后可能会加载日历小部件）：
driver.get("https://eonasdan.github.io/bootstrap-datetimepicker/");
new WebDriverWait(driver, 10)
.until(ExpectedConditions
.elementToBeClickable(By
.xpath("//span[contains(@class,'calendar')]")))
.click();
Files.write(Paths.get("response.html"), driver.getPageSource().getBytes(StandardCharsets.UTF_8));
上一页的输出示例：
<div class="bootstrap-datetimepicker-widget dropdown-menu bottom"
style="display: block; top: 34px; bottom: auto; left: 0px; right: auto;">
<ul class="list-unstyled">
