如何获取活动类值？

Question

我有三个代表std1，std2等标准的链接（锚标记）。我想获得活跃的类值。

  mService.getAPI().getAlbums().flatMap(new Func1<List<PhotoAlbum>, Observable<GetDriversResponse>>() {
                @Override
                public Observable<GetDriversResponse> call(GetDriversResponse mResponse) {
                    return mDatabaseHelper.setMyBus(mResponse);
                }
            }).subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread()).subscribe(new Action1<GetDriversResponse>() {
                        @Override
                        public void call(List<PhotoAlbum> photoAlbums{view().showSearchResult(photoAlbums);  }}, new Action1<Throwable>() {
                        @Override
                        public void call(Throwable throwable) {    
                            throwable.printTrack
                        }
                    }));

的jQuery

                                       <li data-interest="1" class="check <? if($std_id == 1){?> class="active"<?}?>" >
                                            <a href="#1" onclick="changeDiv('1','S1')" data-toggle="tab" title="S1">
                                                <span class="round-tabs green">
                                                    <span class="grade_catgory">S1</span>
                                                </span> 
                                            </a></li>
                                        <li data-interest="2" class="check <? if($std_id == 2){?> class="active"<?}?>" >
                                            <a  onclick="changeDiv('2','S2')" data-toggle="tab" title="S2">
                                                <span class="round-tabs yellow">
                                                    <span class="grade_catgory">S2</span>
                                                </span> 
                                            </a>
                                        </li>

我想要像1,2，等等的值。我可以把它放在哪里？

Answer 1

试试这个：

$("li").each(function(){ // loop through all li
  if($(this).hasClass("active")) { // check if li has active class
    console.log($(this).data("interest")) // get the value of data-interest attribute
  }
})

Answer 2

试试这个：

var val = $('body').find('li.active').attr('data-interest');
