求助一个问题:动态添加删除一个文件控件,添没什么,但删除遇到点问题
代码如下:大侠最好能给出改动后的程序 
 var   fjNo=0; 
 function   addFujian()   { 
       var   str   =    ' <span   name=fj '+   fjNo+ '>  <input   type= "button "   value= "删除 "onclick= "delFujian(    '+fjNo   +    '); ">  <INPUT   type= "file "   size= "40 "   NAME= "File ">  <br>  </span>     ' 
       fjNo++; 
       document.getElementById( 'fjlist ').insertAdjacentHTML( "beforeEnd ",str) 
       document.getElementById( 'addB ').value   =    "继续添加 "; 
 }                                          
 function   delFujian(   no   ){ 
             var   node   =   document.getElementByName(       "fj "+no   ); 
             node.parentNode.removeChild(   node   ); 
 }   
  <body>  
        <form   method= "post "   name= "mail "   action= "tosend.jsp?submit=a "   ENCTYPE= "multipart/form-data "   >  
              <input   type= "button "   value= "添加附件 "   onclick= "addFujian(); "   id= "addB ">  
  </form>  
                 <p   id= "fjlist ">  
                 </p>  
  </body>  
------解决方案--------------------删除也用getElementById呀   
 getElementsByName   you 个 s  ,getElementsByName 取的是个数组,删要用getElementsByName(“”)[0]
------解决方案--------------------function delFujian( no ){ 
     var node = document.getElementsByName(   "fj "+no )[0]; 
     node.parentNode.removeChild( node ); 
 }
