onDelete(name) {
console.log("ProductList.onDelete: ", name);
let {products} = this.state;
products = products.filter(product => product.name !== name);
this.setState({products});
localStorage.setItem('products', JSON.stringify(products));
}
要从本地存储中删除项目，您只需运行：
localStorage.removeItem("name of the item")
let items =JSON.parse(localStorage.getItem("item"));
items = items.filter((item) => item.id !== id);
localStorage.setItem("item", JSON.stringify(items));
if (items.length === 0) {
localStorage.removeItem("item");
}
@Prometheus 是正确的。
既然，你已经要求 ReactJS，我希望下面的小提琴能帮助你：https ://jsfiddle.net/ghoshnirmalya/eqb9vych/5/ 。
addItem = () => localStorage.setItem("name", this.state.name)
removeItem = () => localStorage.removeItem("name")
我在 ReactJS 中添加了一个完整的例子。
