Relative URL to a different port number in a hyperlink?

Question

Is there a way without Javascript / server-side scripting to link to a different port number on the same box, if I don\'t know the hostname?

e.g.:

&l         


        

Answer 1

Based on Gary Hole's answer, but changes urls on page load instead of on click.

I wanted to show the url using css:

a:after {
  content: attr(href);
}

So I needed the anchor's href to be converted to contain the actual url that would be visited.

function fixPortUrls(){
  var nodeArray = document.querySelectorAll('a[href]');
  for (var i = 0; i < nodeArray.length; i++) {
    var a = nodeArray[i];
    // a -> e.g.: Test
    var port = a.getAttribute('href').match(/^:(\d+)(.*)/);
    //port -> ['8080','/test/blah']
    if (port) {
      a.href = port[2]; //a -> Test
      a.port = port[1]; //a -> Test
    }
  }
}

Call the above function on page load.

or on one line:

function fixPortUrls(){var na=document.querySelectorAll('a[href]');for(var i=0;i

(I'm using for instead of forEach so it works in IE7.)
