一、scrollintoviewhtml<div><h2>scrollintoview</h2><button id="roll1">scrollintoview(false)</button><button id="roll2">scrollintoview(true)</button><div><div id="mydiv"></div><div id="roll_top">scrollintoview(ture)元素上边框与视窗顶部齐平<span id="bottom">scrollintoview(false)元素下边框与视窗底部齐平</span></div></div></div>
css #mydiv {height: 900px;background-color: gray; }#roll_top {height: 900px;background-color: green;color: #fff;font-size: 50px;position: relative; }#bottom {position: absolute;display: block;left: 0;bottom: 0; }
js window.onload = function () { document.queryselector(#roll1).onclick = function () { document.queryselector(#roll_top).scrollintoview(false); }; document.queryselector(#roll2).onclick = function () { document.queryselector(#roll_top).scrollintoview(true); }; }
二、滚动监听html<div><h2>scroll</h2><div id="nav"><div class="f1">floor1</div><div class="f2">floor2</div><div class="f3">floor3</div><div class="f4">floor4</div><div class="f5">floor5</div></div><p>页面结构</p><div class="main"><div id="f1">测试1</div><div id="f2">测试2</div><div id="f3">测试3</div><div id="f4">测试4</div><div id="f5">测试5</div></div></div>
css .main div {height: 1000px;width: 300px;margin: 20px;background-color: #c0c0c0; }#nav {position: fixed;width: 100px;height: 200px;top: 40%;right: 10px; }#nav div {cursor: pointer;text-align: center; }
js $(function () { $(window).scroll(function () {//为页面添加页面滚动监听事件var wst = $(window).scrolltop(); //滚动条距离顶端值for (var i = 1; i < 6; i++) { //加循环if ($("#f" + i).offset().top <= wst + 10) { //判断滚动条位置$('#nav div').css("background-color", "white"); $(".f" + i).css("background-color", "red"); } } }); $('#nav div').click(function () { $('html,body').animate({scrolltop: $("#" + this.classname).offset().top}, 500);// $("#" + this.classname)[0].scrollintoview(true);//h5 scrollintoview()}); });
