用过126.com邮件的人都知道,他的功能确实很强大,其中很多细节都是值得我们去学习。
126.com添加附件一直是人们仿效的对象,我记得在以前的时候,点击一次添加附件就出现一个浏览框,现在他也越来月人性话,直接点击就添加附件,这样让用户少了一步操作,也降低了使用的难度。
下面是我仿照网上一些大侠的做法添加自己的理解做的
上传页面:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>仿上126.com上传文件对话框</title>
<script language="javascript">
var i=0;
//点击选择上传文件
function upLoad(){
i++;
var fileBlock = document.getElementById("upFile");
var oDiv = document.createElement("div");
oDiv.id="fileDiv"+i;
oDiv.innerHTML = "<a href=# class=\"addfile\"><input type=\"file\" class=\"addfile\" name=\"file"+(i)+"\" id=\"file"+(i)+"\" onchange='check();'/></a>";
fileBlock.appendChild(oDiv);
}
//当检查点击的文件域
function check(){
if(document.getElementById("file"+i).value != ""){
var fileList=document.getElementById("fileList");
var lDiv=document.createElement("div");
lDiv.id="list"+i;
lDiv.innerHTML = ""+document.getElementById("file"+i).value+" <a href='javascript:delFile("+i+");'><b>×</b></a>;";
fileList.appendChild(lDiv);
document.getElementById("fileDiv"+i).style.display="none";
upLoad();
}
}
//删除选择文件
function delFile(i){
var fileBlock=document.getElementById("upFile");
var oDiv=document.getElementById("fileDiv"+i)
fileBlock.removeChild(oDiv);
//var list=document.getElementById("listFile");
var lDiv=document.getElementById("list"+i)
lDiv.removeNode(true);
}

我通过SA上传组件,做一下上传操作,如下:
<%@ Language=VBScript %>
<%
Function GetFileExt(FullPath)
If FullPath <> "" Then
GetFileExt = LCase(Mid(FullPath,InStrRev(FullPath, ".")+1))
Else
GetFileExt = ""
End If
End function
Set oFileUp = Server.CreateObject("SoftArtisans.FileUp")
oFileUp.Path = Server.MapPath("upfile")
For Each strFormElement In oFileUp.Form
If IsObject(oFileUp.Form(strFormElement)) Then
If Not oFileUp.Form(strFormElement).IsEmpty Then
response.Write oFileUp.Form(strFormElement).ContentType
oFileUp.Form(strFormElement).Save
Response.Write( strFormElement & "|Saved as: " & oFileUp.Form(strFormElement).ServerName & "<br>")
response.Write GetFileExt(oFileUp.Form(strFormElement).ServerName)
Else
// Response.Write(strFormElement)
End If
Else
response.Write(oFileUp.form("name"))
End If
Next
Set oFileUp = Nothing
%>
</BODY>
</HTML>
