js获取页码

function getPageNumberFromURL() {
    const urlParams = new URLSearchParams(window.location.search);
    return parseInt(urlParams.get('page')) || 1; // 默认页码为1
}

// 假设你有一个全局状态管理库Redux
const currentPage = useSelector(state => state.pagination.currentPage);

// 假设你使用Vuex
computed: {
    currentPage() {
        return this.$store.state.pagination.currentPage;
    }
}

function changePage(newPage) {
    const urlParams = new URLSearchParams(window.location.search);
    urlParams.set('page', newPage);
    window.location.search = urlParams.toString();
    // 触发数据加载逻辑
    fetchData(newPage);
}

function calculateTotalPages(totalItems, itemsPerPage) {
    return Math.ceil(totalItems / itemsPerPage);
}
