直接给出代码如下：

    teardown: function(namespaces) {
        var elem = this, $elem = jQuery(elem);
        $elem.unbind(\'click\', jQuery.event.special.tripleclick.handler);
    },

    handler: function(event) {
        var elem = this, $elem = jQuery(elem), clicks = $elem.data(\'clicks\') || 0;
        clicks += 1;
        if ( clicks === 3 ) {
            clicks = 0;
            // set event type to \"tripleclick\"
            event.type = \"tripleclick\";
            // let jQuery handle the triggering of \"tripleclick\" event handlers
            jQuery.event.handle.apply(this, arguments)
        }
        $elem.data(\'clicks\', clicks);
    }
};
