Overlay

我的代码的第 1 行允许我单击主页上的上述时间段，这会触发弹出叠加层。我的目标是单击叠加层上的类(class)预订按钮。根据我的理解，Python需要切换到overlay/iframe。请告知如何编写此代码，因为到目前为止我的尝试尚未成功。

相关主页 HTML:

 <script type="text/javascript">

    $(document).ready(function () {

        setPageScroll('dashboard');

        $(".club-selections a").click(function () {
            $("#ctl00_cphContents_ddlClub").val($(this).attr('rel'));
            $("form:first").submit();
        });

        $(".schedule-selection a").click(function () {
            $("#ctl00_cphContents_ddlSchedule").val($(this).attr('rel'));
            $("form:first").submit();
        });

        $(".club-selections a[rel=" + $("#ctl00_cphContents_ddlClub").val() + "]").addClass('selected');
        $(".schedule-selection a[rel=" + $("#ctl00_cphContents_ddlSchedule").val() + "]").addClass('selected');

        $(".lnkClassInfo").click(function () {
            $.colorbox({
                href: $(this).attr("href"),
                title: $(this).attr("title"),
                transition: 'fade', iframe: true,
                width: 566, height: 600,
                fixed: true
            });
            return false;
        });

        var FIREFOX = /Firefox/i.test(navigator.userAgent);

        if (FIREFOX) {
            $('.tbl-wrapper .tbl-container').scroll(function () {
                $('title').html($(this).scrollLeft());
                $(this).find('a.lnkClassInfo').css('margin-right', $(this).scrollLeft() + "px");
            });
        }

    });
</script>

Highly recommended for those who want a solid foundation in bike set-up &amp; cycling technique. A high energy workout, this indoor cycling workout is paced with light and music settings to create a vibrant atmosphere.<br />
&nbsp;<br />
Push your limits and get intense through warm-up, sprints, climbs and cool-down segments , with changing body positions, pedal speed and resistance.<br />
&nbsp;<br />
<span style="font-size:24px"><strong>Indoor Cycling Experience (I.C.E.) II</strong></span><br />
This programme has proven to be one of the most well-received fat-loss programmes thus far! Simple yet hyper-challenging!<br />
&nbsp;<br />
<span style="font-size:24px"><strong>Indoor Cycling Experience (I.C.E.) III</strong></span><br />
Expectations from participants as well as instructors alike are astronomical! Must have had regular training with Spin II to attempt this class.

最佳答案

您不应该切换到叠加层，因为它只是一个简单的模式窗口(div 节点)。而且目标元素看起来不像输入，而是一个链接

<a id="ctl00_cphContents_btnBook" class="btn-gradient" href="javascript:__doPostBack('ctl00$cphContents$btnBook','')">BOOK THIS CLASS NOW</a>

请尝试以下操作，等待链接出现并单击它:

from selenium.webdriver.support.ui import WebDriverWait as wait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

driver.find_element_by_class_name("lnkClassInfo").click()
wait(driver, 5).until(EC.element_to_be_clickable((By.LINK_TEXT, "BOOK THIS CLASS NOW"))).click()

Here您可以找到有关 iframe 及其外观的更多信息...
