     上面写的html等价于
     $(‘<input type="button" id="btn" value="点击">‘)
     $("#btn").click(function(){  //绑定事件
         console.log(2);
     })
     var ipt = $("#btn").clone(true);  //克隆不克隆事件,如果需要克隆事件需要在后面clone写个true
     $("body").append(ipt);
     var div = document.createElement("div")
     // obox.innerHTML = div;     ×
     // [object Object]
     obox.appendChild(div)
     $("body").html($("<div>"))   ×
     $("body").html("<div>")    //可以直接写元素就创建,input被替换成了·div
     $("body").append($("<div>"))  //插入式创建,创建在script标签后面。
    // clone出的元素,与创建出的元素类型相同,意味着,clone出的元素必须通过append方法插入
