纯前端分页

一、前端分页

<el-pagination 
	v-model:page-size="pageSize" 
	:current-page="currentPage" 
	:page-sizes="[10, 20, 30, 40]" 
	:total="total" 
	background
	layout="total, sizes, prev, pager, next, jumper" 
	@size-change="handleSizeChange"
	@current-change="handleCurrentChange"
/>

setup() {
	const state = reactive({
		pageSize: 10,
		currentPage: 1, // 当前页
		total: 0, // 总条数	
		list:[],
	})
	function getListFun() {
		api().then((res: any) => {
			if (res.status == '1000') {
				state.total = res.data.length;
				state.list= res.data.slice((state.currentPage - 1) * state.pageSize, state.currentPage * state.pageSize);
			}
		})
	}
	function handleSizeChange(data: number) {
		state.pageSize = data;
		state.currentPage = 1;
		getListFun();
	}
	function handleCurrentChange(data: number) {
		state.currentPage = data;
		getListFun();
	}
}
