我有存储对象数组。商店是从具有“完成”和“取消”按钮的弹出组件访问的。我的目标是仅在用户单击“完成”按钮时更新商店。如果弹出窗口关闭或单击“取消”按钮,我不想更新商店。我认为我可以使用局部变量来分配 Store 的值,但即使我更新了局部变量,它也会更新 Store。商店应该这样运作吗?
这是弹出组件

let categorySections = [...$CategorySectionStore];
let categoryLists = [...$CategoryListStore];
let accountSections = [...$AccountSectionStore];
let accountLists = [...$AccountListStore];
let payeeLists = [...$PayeeListStore];
export let togglePopup = () => {};
export let filter;
const toggleCategoryGroup = (groupID) => {
for (let list of categoryLists) {
// console.log(list)
// console.log('gid: ' + groupID)
if (list.Id === groupID) {
list.Checked = !list.Checked;
}
}
}

这里是商店之一。它们都是相同的,只是名称不同。
import { writable } from 'svelte/store';
export const CategorySectionStore = writable([]);
export default CategorySectionStore;
