jquery从JS对象数组中生成多级下拉列表特效

使用方法

        $(function(){
          // parse the data
          languages.forEach(function(item){
            item.label = item.name
            item.value = item.indexcode
            item.children = item.s
            item.s.forEach(function(item2){
              item2.label = item2.name
              item2.value = item2.indexcode
              if (item2.s && item2.s.length) {
                item2.children = item2.s
                item2.s.forEach(function(item3){
                  item3.label = item3.name
                  item3.value = item3.indexcode
                })
              }
            })
          })
          // initialize the plugin on the input field and done
          $('#test').zdCascader({
            data: languages,
            container: '#test',
            onChange: function(value, label, datas){
              console.log(value, label, datas);
            }
          });
        })
