Question

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?

Answer 1

Can you expand the escape function with some custom logic to encode the hypen’s manually?

resource.aspx?original=page%2d%2d1%2d%2dof%2d%2d3.html

Something like this:

function customEscape(url) {
    url = escape(url);
    url = url.replace(/-/g, '%2d');
    return url;
}

location.href = customEscape("resource.axd?original=test--page.html");  

Update, for a bookmarklet:

<a href="javascript:location.href=escape('resource.axd?original=test--page.html').replace(/-/g, '%2d')">Link</a>
