直接给出代码如下：
复制代码 代码如下:
jQuery.event.special.tripleclick = {
    setup: function(data, namespaces) {
        var elem = this, $elem = jQuery(elem);
        $elem.bind('click', jQuery.event.special.tripleclick.handler);
    },

    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);
    }
};


调用时：

复制代码 代码如下:
$('#div').bind('tripleclick', function (event) {
    //do something
});
