如何解决需要帮助更改克隆待办事项列表以使其记录 3 个输出而不是一个 (javascript/html/css/JSON)
我开始更改复制的代码，因此它不是一次发出一个语句的“待办事项”列表，而是想将其更改为一次发出 3 个语句并登录一行。
我可以再添加 2 个盒子，但是当我按下紫色按钮让它运行时，它只记录其中一个盒子，而在其他 2 个盒子（我制作的新盒子）中写入，最终看起来在按下紫色按钮之前像这样：
这会导致注销：
只是名称，但电子邮件不会，它会留下电子邮件和日期的印记（与“用户名框”不同）
尝试修改 eth 代码，但不明白如何操作它以使其显示我想要的内容并记录三件事。你能帮我看看如何做到这一点。以下是 HTML、CSS 和 JS 的 3 个文件。

首先，您从未使用过 email 和 date 的值，因此只显示了 name。
我对您的 listArray 结构进行了一些更改，并将其设为一个对象，类似这样
let userEnteredValue = {
name: inputBox.value,email: email.value,date: date.value
};
为了更好的理解和代码可读性。 然后我对您的 css 进行了一些更改以将其显示在一行中。
我还添加了一个按钮来代替垃圾桶图标，因为我没有引导程序，但您可以再次用图标替换按钮
const inputBox = document.querySelector(".inputField input");
const email = document.querySelector("#email");
const date = document.querySelector("#date");
const addBtn = document.querySelector(".inputField button");
const todoList = document.querySelector(".todoList");
const deleteAllBtn = document.querySelector(".footer button");
// onkeyup event
inputBox.onkeyup = () => {
let userEnteredValue = inputBox.value; //getting user entered value
if (userEnteredValue.trim() != 0) {
//if the user value isn't only spaces
addBtn.classList.add("active"); //active the add button
} else {
addBtn.classList.remove("active"); //unactive the add button
}
};
showTasks(); //calling showTask function
addBtn.onclick = () => {
//when user click on plus icon button
let userEnteredValue = {
name: inputBox.value,date: date.value,}; //getting input field value
console.log(userEnteredValue);
let getLocalStorageData = localStorage.getItem("New Todo"); //getting localstorage
if (getLocalStorageData == null) {
//if localstorage has no data
listArray = []; //create a blank array
} else {
listArray = JSON.parse(getLocalStorageData); //transforming json string into a js object
}
listArray.push(userEnteredValue); //pushing or adding new value in array
localStorage.setItem("New Todo",JSON.stringify(listArray)); //transforming js object into a json string
showTasks(); //calling showTask function
addBtn.classList.remove("active"); //unactive the add button once the task added
};
function showTasks() {
todoList.innerHTML = "";

if (getLocalStorageData == null) {
listArray = [];
} else {
listArray = JSON.parse(getLocalStorageData);
}
const pendingTasksNumb = document.querySelector(".pendingTasks");
pendingTasksNumb.textContent = listArray.length; //passing the array length in pendingtask
if (listArray.length > 0) {
//if array length is greater than 0
deleteAllBtn.classList.add("active"); //active the delete button
} else {
deleteAllBtn.classList.remove("active"); //unactive the delete button
}
// console.log(listArray);
listArray.forEach((element,index) => {
let newLiTag = "";
newLiTag = `<li>${element.name} ${element.email} ${element.date}<span class="icon" onclick="deleteTask(${index})"><button>Delete</button></span></li><br>`;
todoList.insertAdjacentHTML("afterbegin",newLiTag); //adding new li tag inside ul tag
});
// console.log(newLiTag);
inputBox.value = "";
email.value = "";
date.value = ""; //once task added leave the input field blank
}
// delete task function
function deleteTask(index) {
let getLocalStorageData = localStorage.getItem("New Todo");
