url encoding with javascript window open

Question

ASP.NET 4.0, webform site

There is a link in my site is to call another page and pass url parameters, it looks like below.

http://www.foo.com/foo.aspx?anotherURI?param1=aaa&26param2=bbb

However, I need to do url encode for "anotherURI?param1=aaa&26param2=bbb", so it turns into:

http://www.foo.com/foo.aspx?anotherURI?param1%3Daaa%26param2%3Dbbb

Now if I want to enclose this with javascript, it won't work. How do I encode the url again?

javascript:void(window.open('http://www.foo.com/foo.aspx?anotherURI?param1%3Daaa%26param2%3Dbbb', 'popup'))

Answer 1

Correct the URI:

WRONG: http://www.foo.com/foo.aspx?anotherURI?param1%3Daaa%26param2%3Dbbb

RIGHT: http://www.foo.com/foo.aspx?anotherURI=param1%3Daaa%26param2%3Dbbb

Example for multiple URIs: http://www.foo.com/foo.aspc?uri1=[encodedURI]&uri2=[encodedURI2]

To get a value from a queryString variable on asp.net:

Dim sUrl1 as String = request("VarName")
Dim sUrl2 as String = request("VarName")
Dim sUrl3 as String = request("VarName")

If you want to get the decoded URL from that variable:

Dim sDecodedUrl1 as String = Server.UrlDecode(sUrl1)
Dim sDecodedUrl2 as String = Server.UrlDecode(sUrl2)
Dim sDecodedUrl3 as String = Server.UrlDecode(sUrl3)
