问个JavaScript 问题?
我要在top中添加img,可以
var div1=document.getElementById( "top ");
var img=document.createElement( "image ");
img.src= "./Images/luobinmao.jpg ";
div1.appendChild(img);
问题是此处动态添加的img在html中是没有标记的,此时怎么删除?
用removeChild不行!

img.setAttribute( "id ", "image1 ");//设置id为image1
img.src= "../1.jpg ";
div1.appendChild(img);
}
function remove(){
var div1=document.getElementById( "div1 ");
var img=document.getElementById( "image1 ");
div1.removeChild(img);//通过id找到image并删除
}

<body>
<div id= "div1 ">
<input id= "Button1 " type= "button " value= "button " onclick= "remove() " />
</div>

img=null;
div1.innerHTML = " ";
OR
img.style.display = "none ";
