我陷入了这个jQuery本地存储更新问题。我是代码新手，对此一无所知。
我想做的是，当我更改jsonfile值时，我希望本地存储自动更新这个值。我想我错过了什么。
如果有人能帮我的话，这是我的代码。
//start point
$(document).ready(function() {
let jsonData = {};
let ls = false;
jsonData.href = window.location.href;
function getLs() {
if (window.localStorage["local"]) {
ls = JSON.parse(window.localStorage.getItem("local"));
if (ls) {
$.each(ls, (key, val) => {
$("#" + key).text(val);
});
}
}
}
getLs();
// get language from flag click
$("[data-lang]").click(function(e) {
e.preventDefault();
let lang = $(this).attr("data-lang");
let jsonFile = `lang/${lang}.json`;
// get key:value from json files
$.getJSON(jsonFile, data => {
$.each(data, (k, v) => {
// set json file to the localStorage
if ("localStorage" in window) {
let jsonData = JSON.stringify(data);
window.localStorage.setItem("local", jsonData);
$("#" + k).text(v);
}
});
});
});

</html>有一点我的json:
{
"home": "accueil",
"about": "à propos de moi",
"work": "mon travail",
"contact": "me contacter"
}
非常感谢。
无论何时更改json，都必须更新本地存储。
每次更新json时，如果希望它在本地存储中更新，就必须这样做。它不能自动完成。
localStorage.setItem('local', JSON.stringify(yourObject));
var item = JSON.parse(localStorage.getItem('local'));
