var this id=$(this).attr(“id”);
$(thisChildren).each(函数(索引){

});
});

使用 href a 随着 $.map :

$(".sport").on("click", function() {
  let id = $(this).attr("href")
  , list = $.map($(id).find(".sportlist"), function(item){
    return $(item).data("value")      
  })
  console.log(list)
});

下面是另一种不使用id的方法

$(".sport").click(function () {
   let ids = $.map($(this).closest(".panel-heading").next(".panel-collapse").find(".sportlist"), function (element) {
        return $(element).data("value")
    });
    console.log(ids)
});

jQuery closes -对于集合中的每个元素,通过测试元素本身并在DOM树中遍历其祖先来获取与选择器匹配的第一个元素。

jQuery next -获取匹配元素集中每个元素的紧接着的同级。如果提供了选择器,则仅当它与该选择器匹配时,才检索下一个同级。

jQuery find -获取当前匹配元素集中每个元素的子元素,这些子元素由选择器、jQuery对象或元素筛选。

jQuery map -将当前匹配集中的每个元素通过
