前两天写了一个简易的选项卡 封装一下 暂时没发现有什么好处 等以后做的东西多了再说

css
*{ margin: 0; list-style: none; } .ChangeCard{ width: 300px; height: 100px; background-color: red; margin: 100px auto; } #top{ /* margin: 0 auto; */ height: 30px; line-height: 30px; background-color: yellowgreen; text-align: center; } #top li{ display: inline; margin: 0 5px; cursor: pointer; } #button{ margin-top: 25px; text-align: center; } .oks{ color: white; } .oksbox{ display: none; }
js
window.onload = function(){ // 用面向对象封装选项卡 // 要求：传入参数周一周二周三周四周五周六周日的天气 // 当点击相应的选项卡 下方的button会变成对应的内容 // 参数 toJson = { lable : "li", topValue: ["周一","周二","周三","周四","周五","周六","周日"], buttonValue: [ "气温变化平稳，建议穿薄型T恤短裤等夏装", "昼夜温差极大，极易发生感冒，请特别注意增减衣服保暖防寒", "近期空气干燥，注意经常补充水分，以保身体健康", "请各单位、各部门对所在教学楼、办公楼积雪进行清理", "凡在南阳台安装自来水的住户，请保护好水管，以免水管冻裂产生不必要的麻烦", "扣紧门窗，免被强风吹开", "雾霾天气，请减少外出" ], topchange: "ok" } function ChangeCard(toJson){ topCard = document.getElementById("top"); buttonCard = document.getElementById("button"); // 创建内容模块 this.createCard = function(){ for(i=0;i<toJson.topValue.length;i++){ oli = document.createElement("li"); oli.setAttribute("index",i); topCard.appendChild(oli); } } // 点击事件效果模块 this.EventClick = function(){ topCard.children[0].style.color = "white"; buttonCard.innerHTML = toJson.buttonValue[0] for(i=0;i<toJson.topValue.length;i++){ // console.log(111); topCard.children[i].innerHTML = toJson.topValue[i]; topCard.children[i].onclick = function(){ for(i=0;i<toJson.topValue.length;i++){ topCard.children[i].style.color = "black"; } this.style.color = "white" buttonCard.innerHTML = toJson.buttonValue[this.getAttribute("index")]; } } }; } changeCard = new ChangeCard(toJson); changeCard.createCard(); changeCard.EventClick(); }
练习使用没啥看头
