我目前正在从事 Udacity 纳米学位项目，我需要使用 JS 动态创建简历。我移动得很好，直到我撞到了现在的这堵墙，如果有人能帮忙的话，我很乐意帮忙爬过去。

我尝试在我的姓名下附加联系信息，但这些元素始终显示在我的姓名上方。

这是代码的当前状态:

name = "Joel Carter";
title = "Software Developer"
mobile = "708-5xx-xx90"
email = "carter3689@gmail.com"

var formattedName = HTMLheaderName.replace("%data%", name);
var formattedTitle = HTMLheaderRole.replace("%data%", title);
var formatedMobile = HTMLmobile.replace("%data%",mobile);
var formattedEmail = HTMLemail.replace("%data%", email);

$("#header").append(formattedName);
$("#header").append(formattedTitle);
$("#topContacts").prepend(formatedMobile);
$("#topContacts").prepend(formattedEmail);

这也是 HTML(几乎已经得到了这部分)

任何帮助将不胜感激。谢谢

最佳答案

我认为你的问题是 div #header 已经包含 ul 元素#topContacts。因此，您 .append() 的任何内容都将放置在该元素之后。我会尝试 .before(); 而不是 .append();

$('#topContacts').before(formattedName + formattedTitle);

这将在 ul 元素之前插入您的姓名和头衔。然后对于无序列表 #topContacts 尝试:

$('#topContacts').append($('<li>').html(formattedMobile)); 
$('#topContacts').append($('<li>').html(formattedEmail));

这将在 ul 元素内添加一个 li 元素，其中包含您的手机和电子邮件信息的文本。
