如何在 Angular Material 2 中构建自定义组件

是否有任何标准方法可以在 Angular Material 2 之上构建自己的组件或扩展现有组件。之前我使用过 Sencha/ExtJS 框架，构建自己的框架非常简单

svelte：第一次加载时窗口内部宽度未定义

Pinia 对象在 Vue 中的 foreach 后失去反应性

我有这个嵌套的foreach BalanceItemList.vue ... 我有这个嵌套的 foreach BalanceItemList.vue <template> <div v-for="category in categoryItemsStore.balanceCategories" :key="category.id" class="mt-5"> <div class="border-black border-b bg-gray-200"> <span class="font-bold w-full">{{ category.name }}</span> </div> <div v-for="balanceItem in category.balance_items" :key="balanceItem.id"> {{ balanceItem.total = 500 }} <balance-item :balance-item="balanceItem" @update-balance-item="update"/> </div> <div> <balance-item-create :category="category.id" @create-balance-item="update"/> </div> <div v-if="categoryItemsStore.totals[category.id]" class="grid grid-cols-4-b t-2 ml-2"> <div :class="category.is_positive ? '': 'text-red-600' " class="col-start-4 border-t-2 border-black font-bold"> €{{ categoryItemsStore.totals[category.id].total }} </div> </div> </div> </template> 我像这样检查了“balanceItem”的反应性 {{ balanceItem.total = 500 }} 它在商店中更新，但随后我有了我的平衡项目组件： BalanceItem.vue <script setup> import {reactive} from "vue"; import {useForm} from "@inertiajs/vue3"; import NumberInput from "@/Components/NumberInput.vue"; import {UseCategoryItemsStore} from "@/Stores/UseCategoryItemsStore.js"; const categoryItemStore = UseCategoryItemsStore() const props = defineProps({balanceItem: Object, errors: Object}) let item = reactive(props.balanceItem); const form = useForm(item); const emit = defineEmits(['update-balance-item']) const submit = () => { form.post(route('balance-item.update'), { preserveScroll: true, onSuccess: () => { props.balanceItem.total = 500 categoryItemStore.updateBalanceItemsTotals(form) emit('update-balance-item') } }) } </script> <template> <form @submit.prevent="submit"> <div class="grid grid-cols-4-b"> <span>{{ item.name }}</span> <NumberInput v-model="form.count" autofocus class=" mr-4 mt-1 block" type="number" @update:model-value="submit" /> <div :class="item.item_category.is_positive ? '' : 'text-red-600'" class="flex place-items-center"> <div class="pt-1 mr-1">€</div> <NumberInput v-model="form.amount" :class="form.errors.amount ? 'border-red-600' : ''" autofocus class="mt-1 mr-4 w-5/6" type="text" @update:model-value="submit" /> </div> <div :class="item.item_category.is_positive ? '' : 'text-red-600'" class="flex place-items-center"> <div class="pt-1 mr-1 w-5/6">€</div> <NumberInput v-model="form.total" autofocus class="mt-1 block" disabled style="max-width: 95%" type="text" /> </div> </div> </form> </template> 这是我测试反应性的商店。如果我增加输入的数字，则项目的计数保持不变 UseCategoryItemsStore.js import {defineStore} from "pinia"; import {ref} from "vue"; export const UseCategoryItemsStore = defineStore('UseCategoryItemsStore', () => { const balanceCategories = ref([]) const totals = ref([]) function getBalanceItems() { axios.get(route('balance-item.index')).then((response) => { balanceCategories.value = response.data // console.log(balanceCategories.value) }) } function getTotals() { axios.get(route('balance-item.totals')).then((response) => totals.value = response.data) } function getData() { getTotals() getBalanceItems() } function updateBalanceItemsTotals(selectedItem) { balanceCategories.value.forEach((category) => { category.balance_items.forEach((item) => { if (item.id === selectedItem.id) { // item.total = item.count * item.amount console.log(item) } }) }) } getTotals() getBalanceItems() return {balanceCategories, totals, getBalanceItems, getTotals, getData, updateBalanceItemsTotals} }) 在此测试中，我执行“props.balanceItem.total = 500”。但如果我检查商店，它不会更新。看来将“balanceItem”分配给一个道具会失去与我的 Pinia 商店的反应性。我可以使用“form.total = form.count * form.amount”手动更新我的表单，但这对我来说似乎很老套，我想使用 Pinia 商店的反应性。我考虑过根据“BalanceItem”获取 Pina 项目，但这似乎也很棘手。谁知道为什么失去反应性？我有laravel 10.39、vue3.2.41和pinia 2.1.17惯性0.6.11。到目前为止我知道的所有最新版本。我像这样更新我的表格和商店： <script setup> import {useForm} from "@inertiajs/vue3"; import NumberInput from "@/Components/NumberInput.vue"; import {UseCategoryItemsStore} from "@/Stores/UseCategoryItemsStore.js"; const categoryItemStore = UseCategoryItemsStore() const props = defineProps({balanceItem: Object, errors: Object}) let item = categoryItemStore.getItemById(props.balanceItem); let form = useForm(item); const emit = defineEmits(['update-balance-item']) const submit = () => { form.post(route('balance-item.update'), { preserveScroll: true, onSuccess: () => { item = categoryItemStore.updateItem(form) form = useForm(item) emit('update-balance-item') } }) } </script> 我将此功能添加到我的商店： import {defineStore} from "pinia"; import {ref} from "vue"; export const UseCategoryItemsStore = defineStore('UseCategoryItemsStore', () => { const balanceCategories = ref([]) const totals = ref([]) function getBalanceItems() { axios.get(route('balance-item.index')).then((response) => { balanceCategories.value = response.data // console.log(balanceCategories.value) }) } function getItemById(item) { let category = balanceCategories.value.find((category) => { return category.id === item.item_category_id }) return category.balance_items.find((item_from_store) => { return item_from_store.id === item.id }) } function updateItem(form) { const item = getItemById(form) item.count = form.count item.amount = form.amount item.total = item.count * item.amount return item } function getTotals() { axios.get(route('balance-item.totals')).then((response) => totals.value = response.data) } function getData() { getTotals() getBalanceItems() } getTotals() getBalanceItems() return {balanceCategories, totals, getBalanceItems, getTotals, getData, getItemById, updateItem} }) 假设如果帖子获得 200，我的表单值可用于更新商店和更新表单。这是我能想到的最好的
