自写了一个动态添加删除input的实例 贴出来 也许对楼主有帮助<script>
    function addspan(obj,text,id,type)//添加元素
    { 
        var olddiv;
        if(obj==null)
        {
            olddiv=null;
        }  
        else
        {
            olddiv = document.getElementById(obj.id+"span"); 
        }   
        if(olddiv==null)  
        {        
            var span=document.createElement("input");            
            span.className="red";
            span.type=type;
            if(type=="button")
            {
                span.value="删除";                
                span.id="button"+id;
                span.onclick=function(){
                    obj.parentNode.removeChild(span);
                    var text=document.getElementById("text"+id);
                    if(text!=null)
                    obj.parentNode.removeChild(text);                
                };
            }
            span.id="text"+id;
            obj.parentNode.appendChild(span,obj);  
        }
     
    }    function add()
    {        
        hid=document.getElementById("Hidden1");
        var i=hid.value;
        obj=document.getElementById("S_Title");
        addspan(obj,"",i,"text");
        addspan(obj,"",i,"button");
        i++;
        hid.value=i;
    }  
    </script>
<form id="form1" runat="server">
        <div>
            <div>
                标题：<input id="S_Title" type="text" onchange="add()" /></div>
        </div>       
        <input type="button" value="addfile" onclick="add()"/>
