废话不多说了，直接给大家贴js代码了。
<!DOCTYPE html> <html> <head> <script src="/UploadFiles/2021-04-02/jquery-...js">ps：原生JavaScript如何触发滚动条事件"htmlcode">
<script> window.onscroll = function(){ var scrollT = document.documentElement.scrollTop||document.body.scrollTop; var scrollH = document.documentElement.scrollHeight||document.body.scrollHeight; var clientH = document.documentElement.clientHeight||document.body.clientHeight //console.log(scrollT +"+"+scrollH+"+"+clientH); if(scrollT == scrollH - clientH){ console.log("到底部了"); }else if(scrollT == 0){ console.log("到顶部了"); } } </script>
