Javascript 使用JQuery拖放将1分别添加到总计中

使用

jqueryui

，我有一个项目列表，对于每个

拖动
和
拖放
到投票div，我想在span总数中添加1。目前，每次拖放都会在第一个列表项中添加1，我已经尝试了我所知道的一切

JS

$count.droppable({
    accept: "#gallery > li",
    activeClass: "ui-state-highlight",
    drop: function() {
        var el = $('#rj_no');
        var num = parseInt(el.text());
        el.text(num + 1);
        $('#dialog').dialog();
    }
})

$count.droppable({
  activeClass: "ui-state-highlight",
  drop: function(event, ui) {
   if(ui.draggable.is('#rj')) {
      var el = $('#rj_no');
      var num = parseInt(el.text());
      el.text(num+1);
    } else if(ui.draggable.is('#wc')) {
      var el = $('#wc_no');
      var num = parseInt(el.text());
      el.text(num+1);
    } else if(ui.draggable.is('#kk')) {
      var el = $('#kk_no');
      var num = parseInt(el.text());
      el.text(num+1);
