    There are several fallback scripts listed on this page. Basically those scripts check the location.hash at a regular interval. Here is a version that allows only one handler to be bound to the <code>window.onhashchange</code> property:

    (function(window) {
    
      // exit if the browser implements that event
      if ( "onhashchange" in window.document.body ) { return; }
    
      var location = window.location,
        oldURL = location.href,
        oldHash = location.hash;
    
      // check the location hash on a 100ms interval
      setInterval(function() {
        var newURL = location.href,
          newHash = location.hash;
    
        // if the hash has changed and a handler has been bound...
        if ( newHash != oldHash && typeof window.onhashchange === "function" ) {
          // execute the handler
          window.onhashchange({
            type: "hashchange",
            oldURL: oldURL,
            newURL: newURL
          });
    
          oldURL = newURL;
          oldHash = newHash;
        }
      }, 100);
    
    })(window);
