Updated protocol check to respect javascript: pseudo-protocol and hash links (#foo) Updated to support IE

backbone_pushstate_router.js

// Use absolute URLs to navigate to anything not in your Router.
// Note: this version works with IE. Backbone.history.navigate will automatically route the IE user to the appropriate hash URL

// Use delegation to avoid initial DOM selection and allow all matching elements to bubble
$(document).delegate("a", "click", function(evt) {
  // Get the anchor href and protcol
  var href = $(this).attr("href");
  var protocol = this.protocol + "//";

  // Ensure the protocol is not part of URL, meaning its relative.
  // Stop the event bubbling to ensure the link will not cause a page refresh.
  if (href.slice(protocol.length) !== protocol && protocol !== 'javascript://' && href.substring(0, 1) !== '#') {
    evt.preventDefault();

    // Note by using Backbone.history.navigate, router events will not be
    // triggered.  If this is a problem, change this to navigate on your
    // router.
    Backbone.history.navigate(href, true);
  }
