中的待办事项列表中删除项目。
我正在考虑做类似的事情：
localStorage
在这部分代码中：
let deleteTodos = () => {localStorage.removeItem(todos["hola"]); };
这是给您的完整代码以及整个应用的构想
list.addEventListener("click", (e) => {
if (e.target.classList.contains("delete")) {
e.target.parentElement.remove();
localStorage.setItem("todos", JSON.stringify(todos));
}
});
答案 0 :(得分：0)
如果要将字符串化的待办事项保存在“ todos”下的localStorage中，则无法通过localStorage.removeItem(todos["hola"])删除单个项目。
在不评论您是否应该以这种方式使用localStorage的情况下，要删除一项，您需要替换localStorage中的整个对象：
const deleteTodo = (label) => {
// get the items from storage
const oldTodos = JSON.parse(localStorage.getItem('todos'));
// delete the specified item. (however you need to do it. this might not work with your specific data structure)
const newTodos = oldTodos.filter(({ label: x }) => x === label);
// re-reserialize to local storage
localStorage.setItem('todos', JSON.stringify(newTodos));
};
