javascript - 如何仅将门票添加到特定卡目前所有门票都添加到第一张卡

标签 javascript

创建类似 trello 的东西来练习，所以到目前为止我已经创建了三张卡，在每张卡中我想创建门票，但我只能在我的第一张卡中做到这一点，我不知道如何在所有卡片分开，这是我的所有代码

我的html文件

//display username on home screen
let name = Cookies.get('UName');
let dis = name.split('@');
let dispname = dis[0];
document.getElementById('Uname').innerHTML = dispname;


//editable li items on click
document.addEventListener("click", function (e) {
    var elementsIdSelector = "editableLi";
    e = (e || window.event);
    e.preventDefault();
    var path = e.path;
    for (var i = 0; i < path.length - 4; i++) {
        if (path[i].tagName == "LI" && path[i].id == elementsIdSelector) {
            //Found a Li element with the id required ( Even dynamically created li would fires ! )

            path[i].addEventListener("click", function () {
                if (this.getAttribute("contenteditable") != "true") {
                    var wantEdit = window.confirm("You want to edit this card content ?");

现在我想要的是用户可以在每张卡中创建门票 车道，所以任何帮助将不胜感激，我对 js 很陌生

最佳答案

我认为如果你只有树 ul 你可以将 ul id 传递给你的函数

function createEditableLi(ulId) { //here is change to your code
    const ul = document.getElementById(ulId);  ////here is change to your code
    const newLi = document.createElement("li");
    newLi.setAttribute("id", "editableLi");
    ul.appendChild(newLi);
}

这里是对 html 的更改

<section class="lists-container">
        <div class="list" id="dragabble_card">// here change
            <h3 class="list-title">Tasks</h3>
            <form action="/public/card-controller.js" method="POST">
                <ul class="list-items" id="parent_1">
                    <li id="editableLi"> </li>
                    <li id="editableLi"> </li>
                    <li id="editableLi"> </li>
                </ul>
            </form>
            <button class="add-card-btn btn" onclick="createEditableLi('parent_1')">Add a card</button> //here is change to you code
        </div>
        <div class="list" id="dragabble_card">// here change
            <h3 class="list-title">Pending Tasks</h3>
            <form action="/public/card-controller.js" method="POST">
                <ul class="list-items" id="parent_2">//here change
                    <li id="editableLi"> </li>
                    <li id="editableLi"> </li>
                    <li id="editableLi"> </li>
                </ul>
            </form>
            <button class="add-card-btn btn" onclick="createEditableLi('parent_2')">Add a card</button> // here change
        </div>
        <div class="list" id="dragabble_card">
            <h3 class="list-title">Completed Tasks</h3>
            <form action="/public/card-controller.js" method="POST">
                <ul class="list-items" id="parent_3">//here change
                    <li id="editableLi"> </li>
                    <li id="editableLi"> </li>
                    <li id="editableLi"> </li>
                </ul>
            </form>
            <button class="add-card-btn btn" onclick="createEditableLi('parent_3')">Add a card</button> // here change
        </div>
    </section>
