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

    <div class="ChangeCard">
        <div id="top">
            
        </div>
        <div id="button">
           
        </div>
    </div>   
</body>
</html>

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;
}

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
