I want to scrape some data of following url using Python.
http://www.hankyung.com/stockplus/main.php?module=stock&mode=stock_analysis_infomation&itemcode=078340

It's about a summary of company information. 

What I want to scrape is not shown on the first page. 
By clicking tab named "재무제표", you can access financial statement. And clicking tab named "현금흐름표', you can access "Cash Flow". 

I want to scrape the "Cash Flow" data. 

However, Cash flow data is generated by javascript across the url.
The following link is that url which is hidden, http://stock.kisline.com/compinfo/financial/main.action?vhead=N&vfoot=N&vstay=&omit=&vwidth=

Cash flow data is generated by submitting some option value to this url.

Is there good way to scrape cash flow data?
I tried scrapy but scrapy is difficult to cope with my another scraping code already I'm using.
