为什么我不能在列表中添加待办事项？

问题描述

当我在表单中输入并按回车键时，我输入的内容无法显示在内容 div 上。它从“//将项目添加到列表”部分不起作用，我想知道我的 EventListener 或 keyup 有什么问题......（在我的控制台上宣布没有错误）。任何人都可以帮助我吗？谢谢！这是我的 html 文件：

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <link rel="stylesheet"  href="to-do.css">
    <link rel="stylesheet"  href="/css/all.min.css">
</head>
<body>
    <div class="container">
        <div class="header">
            <div class="clear">
                <i class="fas fa-sync-alt"></i>
            </div>
            <div id="date"></div>
        </div>
        <div class="content">
            <ul id="list">
                <!--<li class="item">
                    <i class="far fa-circle co" job="complete" id="0"></i>
                    <p class="text">Drink Coffee</p>
                    <i class="fas fa-trash de" job="delete" id="0"></i>
                </li>-->
            </ul>
        </div>
        <div class="add-to-do">
            <i class="fas fa-plus-circle" ></i>
            <input type="text" id="input" placeholder="Add a-to-do">
        </div>
    </div>
    <script src="to-do.js"></script>


</body>
</html>

这是我的js文件：

const clear = document.querySelector('clear')
const dateElement=document.getElementById('date')
const list=document.getElementById('list')
const input = document.getElementById('input')

//classes name
const CHECK = "fa-check-circle"
const UNCHECK = "fa-circle-thin"
const LINE_THROUGH = "lineThrough"

// show todays date
const options={weekday:"long",month:"short",day:"numeric"} 
const today = new Date()
dateElement.innerHTML=today.toLocaleDateString("en-US",options)

//add to do function

function addTodo(todo){
    const item=`<li class="item">
                    <i class="far fa-circle co" job="complete" id="0"></i>
                    <p class="text">${todo}</p>
                    <i class="fas fa-trash de" job="delete" id="0"></i>
                </li>
                `
    const position="beforeend"
    list.insertAdjacentHTML(position,item)
}
addTodo("Drink Coffe")
// add an item to the list

document.addEventListener("keyup",function(even){
    if(event.keycode==13){
        const todo = input.value;
        //if the input isn't empty
        if(todo){
            addTodo(todo);
        }
        input.value=""

    }
});
