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

最佳答案

我认为如果您只有树ul,则可以将ul id传递给函数

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">
