I have a Javascript bookmarklet that, when clicked on, redirects the user to a new webpage and supplies the URL of the old webpage as a parameter in the query string.
I'm running into a problem when the original webpage has a double hyphen in the URL (ex. page--1--of--3.html
). Stupid, I know - I can't control the original page The javascript escape
function I'm using does not escape the hyphen, and IIS 6 gives a file not found error if asked to serve resource.aspx?original=page--1--of--3.html
Is there an alternative javascript escape function I can use? What is the best way to solve this problem? Does anybody know why IIS chokes on resource.aspx?original=page--1
and not page-1
?
"escape" and "unescape" are deprecated precisely because it doesn't encode all the relevant characters. DO NOT USE ESCAPE OR UNESCAPE. use "encodeURIComponent" and "decodeURIComponent" instead. Supported in all but the oldest most decrepit browsers. It's really a huge shame this knowledge isn't much more common.
(see also encodeURI and decodeURI)
edit: err just tested, but this doesn't really cover the double hyphens still. Sorry.
