    var oContent=document.getElementById("content")

步骤：1、首先正常设置好大盒子里小盒子的样式，然后删除小盒子，只留着样式。这些样式可以统以给剩下的用。

  <style>
        #content{
            width: 1000px;
            margin: 300px auto;
            border: 1px solid #000;
            overflow: hidden;
        }
        .box{
            border: 1px solid #000;
            overflow: auto;
            width: 200px;
            box-sizing: border-box;
            float: left;

        }
        .box p{
            line-height:15x;
            font-size: 14px;
            width: 100%;
        }
        .box span{
            font-size: 16px;
            color: red;
        }
    </style>
</head>
<body>
<div id="content">
        <p>暂时没有货</p>
        <!--<img src="https://img10.360buyimg.com/babel/s180x180_jfs/t1/61418/15/1092/294001/5cf50c2cEe7e8bee5/280ec0703f1db717.jpg" alt="">-->
        <!--<p>苏泊尔（SUPOR)电磁炉 整板触控 SDHC8E15-210D电磁灶（赠汤锅+炒锅）</p>-->
        <!--<span>499</span>-->
</div>

　　　2、当没有数据包时自己制作数据包，制作要求：数组里面有多个对象，每个对象里都是键值对。属性值要用双引号（“”）包裹住，键值对之间用逗号（，）隔开，对象与对象之间也用逗号隔开，一定要注意格式别写错。

 var data=[{
        img:"https://img10.360buyimg.com/babel/s180x180_jfs/t1/61418/15/1092/294001/5cf50c2cEe7e8bee5/280ec0703f1db717.jpg",
        name:"苏泊尔（SUPOR)电磁炉 整板触控 SDHC8E15-210D电磁灶（赠汤锅+炒锅）",
        price:"499"
    },
        {
            img:"https://img11.360buyimg.com/babel/s180x180_jfs/t1/71634/16/6480/286082/5d48e109Ee6ec4ab4/114c9c81eeb8cfa3.jpg",
            name:"美的(Midea) 三门冰箱美的 双门冰箱无霜风冷家用节能静音电冰箱 BCD-231WTM(E)",
            price:"288"
        },
        {
            img:"https://img10.360buyimg.com/babel/s180x180_jfs/t1/61418/15/1092/294001/5cf50c2cEe7e8bee5/280ec0703f1db717.jpg",
            name:"苏泊尔（SUPOR)电磁炉 整板触控 SDHC8E15-210D电磁灶（赠汤锅+炒锅）",
            price:"499"
        },
        {
            img:"https://img10.360buyimg.com/babel/s180x180_jfs/t1/61418/15/1092/294001/5cf50c2cEe7e8bee5/280ec0703f1db717.jpg",
            name:"苏泊尔（SUPOR)电磁炉 整板触控 SDHC8E15-210D电磁灶（赠汤锅+炒锅）",
            price:"499"
        },
        {
            img:"https://img10.360buyimg.com/babel/s180x180_jfs/t1/61418/15/1092/294001/5cf50c2cEe7e8bee5/280ec0703f1db717.jpg",
            name:"苏泊尔（SUPOR)电磁炉 整板触控 SDHC8E15-210D电磁灶（赠汤锅+炒锅）",
            price:"499"
        }
    ];

　3、通过大盒子的id与js实现练习。设置一个空字符串，利用for循环，将设置的数据库data里面的各个属性值一次赋值给str，一定要注意格式。属性值外面要‘+xx.x+’，单引号和加号别搞忘了。

然后将str被赋到的值传给大盒子。str就相当于是小盒子

var oContent=document.getElementById("content")
    var str=""
    for(var i=0;i<data.length;i++){
        str+='<div class="box"><img src="'+data[i].img+'" alt=""><p>'+data[i].name+'</p><span>'+data[i].price+'</span></div> '
    }
    oContent.innerHTML = str;//除了表单标签用value，其他都用innerHTML;
