1. I have a list, and when I swipe to delete it, I get the index, and call localStorage.removeItem (index).. The data in the cache cannot be deleted. Is there something wrong with my writing? I"m going to delete the option to 1 now. What do I do?

localStorage is a key-value pair
list is its key
if you want to delete list, removeItem ('list')
delete the data inside getItem ('list') get the array and then set it
function f(i){
let list = localStorage.getItem('list');
list.splice(i, 1);
localStorage.setItem('list', list);
}upstairs is basically correct, but localStorage can only store strings. A small change based on him
function f(i){
var list = JSON.parse(localStorage.getItem('list'));
list.splice(i, 1);
localStorage.setItem('list', JSON.stringify(list));
