为什么当我点击选择框，javascript创建新的div？

我需要JavaScript函数来创建新的增量divs点击图片！它的作品！但是当我点击选择选项，我不能选择任何选项和JavaScript创建总是新的div。为什么？为什么当我点击选择框，javascript创建新的div？

<script type="text/javascript">  
var i = 1; 
var p = 1; 
function duplicate() { 
    var original = document.getElementById('room'); 
    var subDiv = document.getElementById('subroom'); 
    var clone = subDiv.cloneNode(true); // "deep" clone 
    // document.getElementsByName("st").innerHTML = "Room "+ ++p; 
    clone.setAttribute('class', "sw-room sw-room-"+ ++i); // there can only be one element with an ID 
    //subDiv.setAttribute('class', "sw-room sw-room-"+ ++i); 
    // clone.setAttribute('class', "sw-room sw-room-"+ ++i); // there can only be one element with an ID 
    clone.onclick = duplicate; // event handlers are not cloned 
    var find = document.getElementById('fff'); 
    original.appendChild(clone, find.nextSibling); 
} 
</script>

我需要我的脚本onclick在图像（创建CSS丝毫雪碧）

我可以看到你的HTML吗？ –

你可以请把你的html和js在jsfiddle中。 –

你克隆一个元素与一个ID，从而创建具有相同ID的两个元素。这是不允许的。

也许你可以用类来标记元素？
