[jQuery] How to uninstall the

[Kynn Jones]

I have a jQuery-based script that performs some updates on the current page
(using the load method), and eventually visits a second page, by resetting
window.location.

This works fine, but if the user hits the back button, the whole sequence is
repeated, including the re-loading of the second page.

I'd like to prevent this behavior.  Is it possible?

I tried removing the script with $( 'script[src*=/path/to/script]'
).remove(), but this did not prevent the whole sequence from running again.

Then I thought that the reason for this was that using remove() does not get
rid of the callback that was originally installed at the very end of the
script with jQuery( MyScript.sleep ).  So I tried to uninstall the callback
with $( 'document' ).unbind( 'ready', ... ), but this didn't do anything
either.

How can uninstall the onready callback?  If this is not possible, is there
some other way that I can block the sequence from running a second time when
the user the BACK button?

The script has the following form:

var MyScript = ( function ( $ ) {
  var SELF_URL = location.pathname + location.search;

  var $$; $$ = {
    check: function () {
      if ( $$.results_ready() ) {
        $( 'script[src*=/path/to/script]' ).remove();
        $( 'document' ).unbind( 'ready', $$.sleep );  // is this right???
        window.location = SELF_URL + '&results=1';
      }
      else {
        $$.sleep();
      }
    },

    sleep: function () {
      setTimeout( $$.refresh, 2000 );
    },

    refresh: function () {
      $( 'body' ).load( SELF_URL, $$.check );
    },

    results_ready: function () {
      // etc., etc.
    }
  };

  return $$;
} )( jQuery );

jQuery( MyScript.sleep );



Thanks in advance!
