javascript - python : how to get hidden html contents from a HTML page

Question

我正在尝试制作一个程序，可以使用 robobrowser 重新发行我从图书馆取出的书籍，因此我应该这样做

1) 登录我的ID
2)勾选相应书籍的复选框
3)点击提交

在我登录并打印页面的响应后，它确实打印了页面的源代码，除了包含所有复选框和书籍名称的表单的源代码。

它还应该显示表单的源代码，即

     <tr>
        <td valign="top">   














    <form action="./selectedBooks" method="get" id="form1" target="nid">
    <table border="0" class="briefListTbl" cellspacing="0" cellpadding="0" 
    valign="top">
    <tbody><tr><td>
    <table valign="top" border="0" cellspacing="0" cellpadding="0" height="100%" 
    width="100%">
       <tbody class="briefListHead">
    <tr align="middle">

                </tbody></table></td>



</tr>


</tbody></table>



                </form></td></tr> 

但它只是打印

<tr><td valign="top">
</td></tr>
</table>
</td>
</tr>
</table>

和我的代码..

browser = RoboBrowser(parser='lxml', user_agent='Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.11 (KHTML, like Gecko) Chrome/23.0.1271.64 Safari/537.11', history=True, session=start)


browser.open('http://61.12.27.181:8080/opac/html/checkouts')
sign_in = browser.get_form(action='./memberlogin')
sign_in['txtmemberid'].value = 'MyId'
browser.submit_form(sign_in, submit='  Go  ')
box = browser.get_form(action='./selectedBooks')
print(browser.parsed)

整个td标签丢失了，我不认为这是因为robobrowser因为我也在传递 session ，那么为什么会发生
有什么帮助吗？

Answer 1

可以通过检查元素即从网络选项卡添加脚本 URL 来解决这个问题

1) 转到检查元素工具中的网络选项卡。
2) 获取具有 ok 响应的 js 或 css 的 url 并使用 browser.session Robobrowser 中的 .get(url_of_js_or_css) 和请求中的 requests.get(url)

祝你好运!
