I click on the three images to return this data. How can I get the corresponding value?

Java javascript

I don't quite understand what you want to ask. There's nothing wrong with your code, and so is the output. What's wrong with it?

< hr >

look at it again. Is there something wrong with what you write here? 

var id = $(".Grand_Template").attr("data-id");

it seems to me that every class class name is this Grand_Template ?

so the you get in this step is the first of the three same class classes. Do you want to get the following? What you get should be a group, and there are several that you can cycle out

. 
console.log($(".Grand_Template").data("grade_id"))

this is a data- attribute of h5, which is obtained by dataset method in native js. Use $(''). Data ()) to get

in jq.

this is api http://jquery.cuishifeng.cn/d.

hope to be useful to you, welcome to follow: Front end Guide official account 
$(".jiepan_swiper").on("click","img", function() { 
    var $item = $(this).parents(".Grand_Template");
    var grade_id = $item.attr("data-grade_id");
    console.log(grade_id);
    var id = $item.attr("data-id");
    console.log(id);
    var teacher = $item.attr("data-teacher");
    console.log(teacher);
    var content = $item.attr("data-video_url");
    console.log(content);
    //window.location.href = "v_play.html?grade_id=" + grade_id + "&id=" + id + "&teacher=" + teacher + "&content=" +content;

});
