思路：第一步：当页面加载完后，获取所要操作的节对象第二步：为document添加一个滚轮滚动事件第三步：滚轮滚动切换获取当前浏览器可视区域的高度var viewHeight = document.body.clientHeight滚轮切换的目的：就是更改bigBox的top值top:最大0top:最小 viewHeight*-4从上到下或从下到上：最多走4次(5个页面) 每一次走viewHeight控制的关键点：索引 定一个索引 2滚轮↓索引+1滚轮↑索引-1bigBox.style.top = -索引*viewHeihgt */var bigBox = document.getElementById("bigBox");//获取bigBox节点对象var lis = document.querySelectorAll(".controls li");//获取所有的li节点对象var viewHeight = document.body.clientHeight;//获取当前页面高度var flag = true;//设置开关var index = 0;//设置索引//封装事件,兼容浏览器function on(obj,eventType,fn){if(obj.addEventListener){obj.addEventListener(eventType, fn);}else{obj.attachEvent("on" + eventType, fn);}}//鼠标滚动事件处理函数function handler(e){var _e = window.event || e;if(flag){flag = false;if(_e.wheelDelta==120 || _e.detail==-3){//如果鼠标滚轮向上滚动，detail为火狐判断条件index--;if(index<0){index = 0;}}else{//向下滚动index++;if(index>lis.length-1){//如果索引大于页面数，就是滚到最后一张页面时，再滚动鼠标页面不再滚动index = lis.length-1;}}bigBox.style.top = -index*viewHeight + "px";//bigBox整体上移index个页面for(var i=0; i<lis.length; i++){lis[i].className = "";//重置全部li的类}lis[index].className = "active";//设置当前li的类名setTimeout(function(){//页面滚动间隔一秒，防止滚动太快flag = true;//重新开启开关},1000);}}on(document,"mousewheel",handler);//滚轮滚动事件on(document,"DOMMouseScroll",handler);//滚轮滚动事件，适配火狐浏览器//数字标签点击处理for(var i=0; i<lis.length; i++){lis[i].tag = i;lis[i].onclick = function(){for(var j=0; j<lis.length; j++){lis[j].className = "";}lis[this.tag].className = "active";bigBox.style.top = -this.tag*viewHeight + "px";}}

对应的html代码：
<p>点击各个选项切换内容:</p><div id="London" class="tabcontent"><h3>London</h3><p>London is the capital city of England.</p></div><div id="Paris" class="tabcontent"><h3>Paris</h3><p>Paris is the capital of France.</p> </div><div id="Tokyo" class="tabcontent"><h3>Tokyo</h3><p>Tokyo is the capital of Japan.</p></div><div id="Oslo" class="tabcontent"><h3>Oslo</h3><p>Oslo is the capital of Norway.</p></div><button class="tablink" onclick="openCity('London', this, 'red')" id="defaultOpen">London</button><button class="tablink" onclick="openCity('Paris', this, 'green')">Paris</button><button class="tablink" onclick="openCity('Tokyo', this, 'blue')">Tokyo</button><button class="tablink" onclick="openCity('Oslo', this, 'orange')">Oslo</button>
对应的js代码：
function openCity(cityName,elmnt,color) {var i, tabcontent, tablinks;tabcontent = document.getElementsByClassName("tabcontent");for (i = 0; i < tabcontent.length; i++) {tabcontent[i].style.display = "none";}tablinks = document.getElementsByClassName("tablink");for (i = 0; i < tablinks.length; i++) {tablinks[i].style.backgroundColor = "";}document.getElementById(cityName).style.display = "block";elmnt.style.backgroundColor = color;}// 触发 id="defaultOpen" click 事件document.getElementById("defaultOpen").click();
对应的css代码：
body {font-family: "Lato", sans-serif;}.tablink {background-color: #555;color: white;float: left;border: none;outline: none;cursor: pointer;padding: 14px 16px;font-size: 17px;width: 25%;}.tablink:hover {background-color: #777;}/* Style the tab content */.tabcontent {color: white;display: none;padding: 50px;text-align: center;}#London {background-color:red;}#Paris {background-color:green;}#Tokyo {background-color:blue;}#Oslo {background-color:orange;}
