JS simply implements sliding loading data instance sharing

//滑动 function getScrollTop() { var scrollTop = 0; if (document.documentElement && document.documentElement.scrollTop) { scrollTop = document.documentElement.scrollTop; }else if (document.body) { scrollTop = document.body.scrollTop; } return scrollTop; } //获取当前可视范围的高度 function getClientHeight() { var clientHeight = 0; if (document.body.clientHeight && document.documentElement.clientHeight) { clientHeight = Math.min(document.body.clientHeight, document.documentElement.clientHeight); }else { clientHeight = Math.max(document.body.clientHeight, document.documentElement.clientHeight); } return clientHeight; } //获取文档完整的高度 function getScrollHeight() { return Math.max(document.body.scrollHeight, document.documentElement.scrollHeight); } //绑定事件 window.onscroll = function () { if (getScrollTop() + getClientHeight() == getScrollHeight()) { //dosomething } }
