我有以下代码段：
(document)
.on("submit", ".edit-employee-form", function (e) {
e.preventDefault();
$.ajax({
type: "POST",
url: $(this).attr("action"),
method: $(this).attr("method"),
dataType: "html",
context: this,
data: $(this).serialize(),
success: function (response) {
p = $(this).parent();
p.prevAll('#first-name').html($(this).find("#first_name").val());
p.prevAll('#last-name').html($(this).find("#last_name").val());
p.prevAll('#email').html($(this).find("#email").val());
p.prevAll('#remain_case').html($(this).find("#remain_case").val());
$(this).parent().hide();
console.log('yay');
},
error: function (response, error) {
console.log("ERROR");
console.log(response);
console.log(error);
}
});
}
）;
它的作用是提交表格来编辑特定员工（页面上显示一个列表），然后更新html以反映用户提交的更改。
我的问题是，一些员工也是通过ajax调用添加的，因此他们相应的列表元素会动态添加到html中。我似乎无法使用id名字，姓氏，电子邮件等访问他们的div。有关如何选择动态添加的div的任何建议吗？
我很抱歉这是一张图片，但我似乎无法复制Chrome控制台。第二个元素是动态添加的。

答案 0 :(得分：1)
你的代码应该确定完成ajax调用的顺序，因为用人眼看它太快了。如果未完成追加ajax调用，则无法使用偶数元素id选择这些元素。
为此，您应该在“成功处理程序”中放置ajax函数调用。 如果第一个是成功，那么在一个成功处理程序中排名第二，在两个成功处理程序中排在第三，依此类推......
简单的解决方案是使用PROMISE按顺序获取所有ajax相关函数。 请参阅链接：https://api.jquery.com/promise/
要检查元素是否已成功追加，请使用“console.info或console.log”或类似内容检查控制台。如果长度为0，则附加的ajax调用尚未完成。
