我看了一下发生了什么。它打开正常，但在打开期间，它会注册一个文档点击处理程序，关闭菜单以响应菜单外的任何点击，并且此处理程序立即处理按钮上的点击。你应该能够像这样停止处理这个点击的处理程序：

$(function () {
    $( "#speed" ).selectmenu();
    $('#btn').click(function(event){
        $( "#speed" ).selectmenu('open');
        event.stopPropagation();
    });
});

如何从javascript打开JQuery selectmenu插件？
