{
    var url = 'lib/ajax_request.php';
    var params = 'action=login&login=' + $F( 'form_login' ) + '&pass=' + $F( 'form_pass' );
    
    function login()
    {
        var ajax = new Ajax.Request( this.url, { parameters: this.params, onLoading: msgBox( 'SHOW', 'Loading...' ), onSuccess: msgBox( 'Logged...' ), onFauilure: reportError} );
        switch( ajax.responseText )
        {
            case 'OK': this.msgBox( 'SHOW', 'Logged ...' ); this.pause( 1000 ); this.msgBox( 'HIDE', '' ); break
                
        }
    }
    
    function msgBox( type, msg )
    {
        $F( 'msg_box' ).innerHTML = msg;
        switch( type )
        {
            case 'HIDE': $F( 'msg_box' ).style.display = 'none'; break
            case 'SHOW': $F( 'msg_box' ).style.display = 'block'; break
        }
    }
    
    function pause( ms )
    {
        var now = new Date();
        var exitTime = now.getTime() + ms;
    
        while( true )
        {
            now = new Date();
            if( now.getTime() > exitTime ) return;
        }
    }
