获取到以后元素,而后获取以后元素的高度、滚动条间隔顶部高度,滚条高度,从而进行判断。
代码如下:

that.$nextTick(() => {    const el = document.querySelector('.reg-pro-wrap');    const offsetHeight = el.offsetHeight;    el.onscroll = () => {        const scrollTop = el.scrollTop;        const scrollHeight = el.scrollHeight;        if ((offsetHeight + scrollTop) - scrollHeight >= -1) {            // 须要执行的代码            console.log('已滚动到底部')            that.disabled = false;        }    };});
