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
});
