jquery-mobile - jQuery Mobile 是否有现有的按字母顺序排列的列表小部件？

Question

我希望使用 jQuery Mobile 创建这个常见的(在 iPhone 上)列表类型:



关键功能是从右侧向下运行的字母表，它将滚动到最接近的匹配项。

像这样的东西已经存在还是我需要自己动手？我无法在演示中找到它，尽管 List dividers让我在那里的一部分。

嗯，这是一项正在进行的工作，但我认为可以完成。例子:

http://jsfiddle.net/qXT9Z/32/

CSS

#list-navigation {
    color:#696969;

    position:absolute;
    right:0px;
    top:0px;
    z-index:200;
}

JS

$('.scrollToSelected').bind('click', function() {
    var view = $(this).attr('id');
    var list = view.split('-');
    var elem = $("#"+list[1]);

    // not sure if this is offset or position
    var position = elem.position(); 
    var offset   = elem.offset();

    //alert('left: '+position.left + ", top: " + position.top);
    //alert('left: '+offset.left + ", top: " + offset.top);

    $.mobile.silentScroll(position.top);
    //$.mobile.silentScroll(offset.top);

});

$('.showDetails').bind('click', function() {
    $.mobile.changePage( "#details", { transition: "slideup"} );
});
