多附件的上传

   
1、JS代码

 1function addFileControl()
 2         {
 3         var str='<input type=file name=File size=40>'
 4         document.getElementById('FileCollection').insertAdjacentHTML("beforeEnd",str)
 5         }
 6         
 7          function delFile()
 8         {
 9            var el = document.getElementById("FileCollection");
10            if (el.hasChildNodes())
11               el.removeChild(el.lastChild);
12         }

    2. 前台代码 

1<p id="FileCollection">
2                                        <input type="file" name="File" id="file" size="40" />
3                                    <p>
4                                        <%--<input type =image onclick="addFileControl()"   src="../Images/tianjia.gif"  value="增加"/>--%>
5                                        <input type="button" value="增加" onclick="addFileControl()" class="button" />
6                                        &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
7                                        <input type="button" value="取消" onclick="delFile()" class="button" /></p>
