Open URL with a set Target

EDIT: The solution I am seeking is a command line to be run to accomplish this from a batch file in Windows.

How would I mimic a browser function to open a URL with a specific target so that if that tab is already open it will load there instead of creating a new tab?

So instead of the default http://url.com with the target "_blank", I could change this to "w00t", etc.

I am using Chrome exclusively, so if this were to be a Chrome specific command, that would be acceptable.

Solution

You could create a HTML-page and add the following code like this:

<script>
  var url = getQueryVariable("url");
  var target = getQueryVariable("target");
  window.open(url,target);

  function getQueryVariable(variable) {
    var query = window.location.search.substring(1);
    var vars = query.split("&");
    for (var i=0;i<vars.length;i++) {
    var pair = vars[i].split("=");
      if (pair[0] == variable) {
        return pair[1];
      }
    }
  }
</script>

I have this script hosted here: scriptcoded.github.io/redirect

You could then call it from a batch-file using this command:

START scriptcoded.github.io/redirect?url=http://www.google.com&target=w00t

Use ?url=http://www.google.com&target=_blank to set the redirect.

The only problems I find with this method is that some browsers blocks the new window and that the tab won't close. Yes, we could use window.close();, but it will only close tabs that were opened by the webpage itself.

Hope it helps!
