vue3 滚动到底部触发方法

import { onMounted, onBeforeUnmount, ref } from 'vue';
const logs = ref(null) // 绑定到滚动的盒子上
onMounted(() => {
    window.addEventListener('scroll', handleScroll, true);
})
onBeforeUnmount(() => {
    window.removeEventListener('scroll', handleScroll, true);
})
const handleScroll = () => {
    // 总数据条数大于当前已加载条数
    if (state.logsTotal > state.logsArr.length) {
        var scrollHeight = logs.value.scrollHeight
        var scrollTop = logs.value.scrollTop
        var clientHeight = logs.value.clientHeight
        //滚动条滚到最底部
        if (scrollHeight - clientHeight == scrollTop) {
            ... // 在这里调用加载数据的方法
        }
    }
}
