如何在网站上选择框架元素？

Question

我想在网站上运行以下代码：

import datetime
current_time = datetime.datetime.now()
now = datetime.time(current_time.hour, current_time.minute)
if datetime.time(22, 0) <= now <= datetime.time(23, 0):
    print "current time is between 10:00pm to 11:00pm":
else:
    print "current time is NOT between 10:00pm to 11:00pm"

问题是我必须选择框架“ EditForm.aspx”：

在IE中，我可以通过手动单击轻松地选择框架，但是我只想在JavaScript中完成，而无需手动选择。

我尝试过

document.getElementById("FileLeafRef_8553196d-ec8d-4564-9861-3dbe931050c8_$onetidIOFile").value = "test";

但是我认为这是错误的路径...
