There are times when developing in SharePoint where you will be required to modify existing links on a page to make those links open in a new window (Document Library, Links List, etc.).  There are times when the original anchor tag carries an “onclick” event of “GoToLink(this); return false;”.  The original “GoToLink” function will not allow for opening even links with a modified target in a new window.  The following is a piece of JavaScript that will allow for overriding the original “GoToLink” function.

Note:  For those links where I truly wish to override the “GoToLink” behavior, I attach a custom attribute to the anchor to be sure it is truly a link I have manipulated.

//Create a custom GoToLink function
var _origGoToLink = GoToLink;
GoToLink = function(elm) {
  if (elm.href == null)
    return;
  var ch = elm.href.indexOf(\"?\") >= 0 ? \"&\" : \"?\";
  var srcUrl = GetSource();
  if (srcUrl != null && srcUrl != \"\")
    srcUrl = ch + \"Source=\" + srcUrl;
  var targetUrl = elm.href + srcUrl;
  if (elm.getAttribute('cnWebPartsHref') != null) {
    //Use window.open rather than window.location
    window.open(STSPageUrlValidation(targetUrl));
  }
  else {
    window.location = STSPageUrlValidation(targetUrl);
  }
}
