javascript-.remove()无法在成功功能上使用Ajax

我有一些使用jinja2生成的html div：

{% for student in students %}
<div class="item" id="{{ student.id }}_div">
   <div class="right floated content">
      <div class="negative ui button compact remove_from_class" id="{{ student.id }}">Remove from Class</div>
   </div>
   <i class="large user icon middle aligned icon"></i>
   <div class="content">
      <div class="header">
         <h3><u>{{ student.get_full_name }}</u></h3>
      </div>
      <div class="description">{{ student.email }}</div>
   </div>
</div>
{% endfor %}

这是我拥有的脚本,该脚本获取父divs ID,然后尝试使用.remove()删除它.

$(".remove_from_class").each(function () {
$(this).on("click", function () {
    var id = this.id;
    var url = window.location.pathname.split('/');
    var set_id = url.pop() || url.pop()


    $.ajax({
        method: 'POST',
        url: '/ajax/delete_from_class/',
        data: {
            'id': id,
            'set_id': set_id,
        },
        dataType: 'json',
        success: function (data) {
            if (data.success == true) {
                var div_id = id + "_div";
                var parent_div = $(div_id);
                parent_div.remove();

            } else {
                alert("Student wasn't removed!");
            }

        }
    })
})
})

但是,即使显示成功弹出窗口,也不会删除div.

谢谢你的帮助！

解决方法:

您需要使用#来将id用作选择器.

var div_id = "#"+id + "_div"; // Use # here
var parent_div = $(div_id);
parent_div.remove();

或者我建议的更好的方法是将div存储在.click中的某个变量中,然后再使用它.

$(".remove_from_class").each(function () {
$(this).on("click", function () {
    var $parentDiv = $(this).closest(".item"); // Save it here
    var id = this.id;
    var url = window.location.pathname.split('/');
    var set_id = url.pop() || url.pop()


    $.ajax({
        method: 'POST',
        url: '/ajax/delete_from_class/',
        data: {
            'id': id,
            'set_id': set_id,
        },
        dataType: 'json',
        success: function (data) {
            if (data.success == true) {
                $parentDiv.remove(); // And remvoe it here

            } else {
                alert("Student wasn't removed!");
            }

        }
    })
})
})
