How to get javascript link

ydnh2222

I want to get the uri address of the corresponding attachment (.doc / .pdf format) from the link on a webpage and download it. How to achieve it by using a program to obtain the uri under the .net and automatically download it using a program? I always think that if an attachment If uri is implemented in javascript, my program will not get this link. I wonder if there is a good way for heroes?

use dom

Using the webbrowser control, after downloading the URL
Get the document property of webbroswer and use dom to analyze the URLs in it

Does webbroswer need to execute that js function, otherwise, how can we get the real url? Know that we can't get the url based on the literal of the js function.
If webbroswer executes js functions, how to execute them, aren't those js function codes on the server of other websites, how do I get the source code of js?
Online etc ...

I saw that js code can be executed with dom in other places, but I don’t know if I can still get the url link. Expert enlightenment

Use regular expressions to extract URLs and execute javascript using methods in webbrowser. You can check on the Internet for details.
