将这两个元素添加到我的 HTML 文件中的无序列表中

问题描述 投票：0回答：1

我目前正在尝试创建评论部分，我可以设法让用户输入他们的姓名和评论，并且我还完成了创建列表，但是我无法将输入的名称和评论都添加到列表中作为评论。你能修复 Javascript 以将名称和评论添加到列表中吗？我想修复我的 favascrpt，这样我就可以将我的元素“comment”添加到我添加的名为“list”的 ID 的列表中。

// JavaScript Document
function titleSubmit() {
  document.querySelector("titleNameinput");
  document.querySelector("message");
  document.getElementById("message").innerHTML = titleNameinput.value;
}

function CommentSubmit() {
  document.querySelector("CommentSubmitinput");
  document.querySelector("comment");
  document.getElementById("comment").innerHTML = CommentSubmitinput.value;
}

function AddItemsintoList() {
  document.querySelector("list")
  document.querySelector("comment");
  list.append("comment")
}
@charset "utf-8";

问题是您仅替换了现有 

#title
和 
#message
段落元素中的字符串。您需要做的就是向
#list
添加新元素。一种方法是使用 
.innerHTML
并不断添加新的字符串元素。此示例展示了如何使用模板文字将变量插入到字符串中。

此外，在元素上使用 

on-click
是一个不好的标准。您应该使用 
addEventListener
。

此外，删除了不相关的 HTML 代码。

document.getElementById("commentBtn").addEventListener("click", addComment);

function addComment() {
  const listElement = document.getElementById("list");
  const titleValue = document.getElementById("titleNameinput").value;
  const commentValue = document.getElementById("CommentSubmitinput").value;
  
  listElement.innerHTML += `
        <li>
          <p class="message">${titleValue}</p>
          <p class="comment">${commentValue}</p>
        </li>
  `
}
