Struts里面上传多附件例子

首先说ActionForm

public class AykjArtistForm extends ActionForm{
     //有那么麻烦吗,还要写什么LIST在里面,不用的..当然了其它参数就看你的情况了
}

Action里面就这样处理

ArrayList list= new ArrayList();//用来装FormFile
Hashtable fileh = form.getMultipartRequestHandler().getFileElements();//form是传过来的参数
for(Iterator it = fileh.keySet().iterator(); it.hasNext();){   
    String key = (String) it.next();   
    FormFile formfile = (FormFile) fileh.get(key);//获取一个FormFile
    list.add(formfile);//装进去
}

再看HTML文件

<div id="artist">
    <div id="myupload0">
        <input type="file" id="file0" name="photo(0)" onchange="addinput(0)">
    </div>
</div>

//js文件
<script type="text/javascript">
	 var i = 0;
	 function addinput(numline){
	 	var divid = "divid"+(numline+1);
	 	if(document.getElementById(divid)){
	 		return;
	 	}
	 	i++;
		var myHTML = "<input type='file' id='file"+(numline+1)+"' name='photo("+(numline+1)+")' onchange='addinput("+(numline+1)+")'>";
		var pdiv = document.getElementById("artist");
		var div = document.createElement("div");
		var divids = "divid"+(numline+1)
		div.setAttribute("id",divids);
		/*var inputHTML = document.createElement("input");*/		
		/*var inputHTMLnum = "artistPhoto("+numline+")";*/
		div.innerHTML = myHTML;
		/*div.appendChild(inputHTML);*/
		pdiv.appendChild(div);		
	}
</script>
