Question

这是我第一次涉足Selenium。如果这是一个愚蠢/琐碎的问题，请提前道歉。

我正在尝试从网页上抓取信息。使用Python / Selenium，我可以登录该站点并访问包含我需要的信息的页面。在显示我需要的页面后，我正在发布

time.sleep(20)
html_source = driver.page_source
print html_source

＆＃34;来源＆＃34;被打印的不同于右键单击并选择查看页面源和右键单击并选择此框架，查看框架源

所需信息位于View Frame源中。所有这一切都在Firefox中。

到达Frame Source需要做什么？帧源中没有帧名称。

以下附加信息：

当我右键单击并选择查看页面源时，我得到以下内容：

                    {
                        frameDetail.focus();
                    }

                    function addInProgressPanel(doc)

                        td.bgcolor="red";

                        row.appendChild(td);

                        td = doc.createElement("td");
                        td.className="inProcessing";
                        td.appendChild(doc.createTextNode("Your Request is Being Processed  ..."));
                        row.appendChild(td);

                        d.appendChild(tbl);
                        doc.body.appendChild(d);
                        return d;
                    }

                    function inProgressScreen(type)
                    {
                        var ws = frames["frameDetail"];
                        if(!ws) return true;
                        var ips = ws.document.getElementById("inProgressPane");
                        if(ips)
                        {
                            if(type)  ips.className = 'freezeOn';
                            else      ips.className = 'freezeOff';
                        }else if(type)
                            ips = addInProgressPanel(ws.document);

   </frameset>
</html>

当我右键单击并选择This Frame，View Frame source I get

<!DOCTYPE html><html>
   <head>
      <meta http-equiv="Content-Type" content="text/html; charset=utf-8">

这里有更多代码。没贴，因为它太长了。除了以下对iSessionFrame的引用之外，没有框架名称：

    </script><script language="javascript" src="portal/grades.js"></script></div>
            </div>
         </div>
         <div id="footer">
            <table id="language"><select id="locale" style="width:175px"></select></table>
         </div>
      </div><iframe id="iSessionFrame" name="iSessionFrame" width="0" height="0" src="https://website.org/xxxxxx/white.jsp" style="visibility:hidden;"></iframe></body>
</html>

Answer 1

问：我需要做什么才能到达Frame Source？

A：首先，您必须使用switch_to命令切换到所需的帧，然后您应该使用.page_source来获取html源。

Obs。：查看Selenium文档，更具体地说是Moving between windows and frames。

代码：

driver.switch_to_frame(driver.find_element_by_tag_name("frameDetail"))
driver.page_source

Answer 2

您可以尝试使用其ID切换到框架：

driver.switch_to_frame(driver.find_element_by_id("iSessionFrame"))
driver.page_source

Python selenium打印帧源
