2.分页组件

</template><script setup lang="ts" name="pagination">
const emit = defineEmits(['sizeChange', 'currentChange']);const props = defineProps({current: {type: Number,default: 1,},size: {type: Number,default: 10,},total: {type: Number,default: 0,},pageSizes: {type: Array as () => number[],default: () => {return [1, 10, 20, 50, 100, 200];},},layout: {type: String,default: 'total, sizes, prev, pager, next, jumper',},
});
// 分页改变
const sizeChangeHandle = (val: number) => {emit('sizeChange', val);
};
// 分页改变
const currentChangeHandle = (val: number) => {emit('currentChange', val);
};
</script>
