ASP.net .net ASP Web JavaScript

1.在工具箱中添加Brettle.Web.NeatUpload.dll，可以看到工具箱中出现InputFile等控件。
2.复制文件夹NeatUpload到根目录.
3.拖放使用上传控件InputFile和进度条ProgressBar,添加上传文件的按钮.aspx页面代码如下：

[复制此代码]CODE:
<body>
<form id="form1" runat="server">
<div>
<upload:InputFile id="AttachFile" runat="server"></upload:InputFile>
<asp:Button ID="Upload" runat="server" Text="Upload" OnClientClick="ToggleVisibility('ProgressBar','on')" OnClick="Upload_Click"/>
<div id="ProgressBar" style="display:none;">
<upload:progressbar id="pbProgressBar" runat="server" Inline="true" Width="500px" Height="100"> </upload:progressbar>
</div>
</div>
</form>
</body>

4.添加脚本代码ToggleVisiblity函数到页面上如下：
[复制此代码]CODE:
<script type="text/javascript" language="javascript">
function ToggleVisibility(id, type)
{
el = document.getElementById(id);
if(el.style)
{
if(type == 'on')
{
el.style.display = 'block';
}
else
{
el.style.display = 'none';
}
}
else
{
if(type == 'on')
{
el.display = 'block';
}
else
{
el.display = 'none';
}
}
}
</script>

5.给上传文件的按钮添加事件Upload_Click
[复制此代码]CODE:
protected void Upload_Click(object sender, EventArgs e)
{
string FileName = this.AttachFile.FileName;//获取上传文件的全路径
string ExtenName = System.IO.Path.GetExtension(FileName);//获取扩展名
string SaveFileName = System.IO.Path.Combine(Request.PhysicalApplicationPath, DateTime.Now.ToString("yyyyMMddhhmm") + ExtenName);//合并两个路径为上传到服务器上的全路径
if (this.AttachFile.ContentLength > 0)
{
try
{
this.AttachFile.MoveTo(SaveFileName, Brettle.Web.NeatUpload.MoveToOptions.Overwrite);
}
catch (Exception ex)
{
throw ex;
}
}
}

6.在配置文件web.config中添加http模块声明:
[复制此代码]CODE:
<httpModules>
<add name="UploadHttpModule" type="Brettle.Web.NeatUpload.UploadHttpModule, Brettle.Web.NeatUpload" />
</httpModules>

7.需要在web.config进行其他一些设置才能保证完美。
在<configuration>里面加入
[复制此代码]CODE:
<configSections>
<sectionGroup name="system.web">
<section name="neatUpload" type="Brettle.Web.NeatUpload.ConfigSectionHandler, Brettle.Web.NeatUpload" allowLocation="true" />
</sectionGroup>
</configSections>

在 <system.web>加入
[复制此代码]CODE:
<neatUpload useHttpModule="false" maxNormalRequestLength="4096" maxRequestLength="2097151" defaultProvider="FilesystemUploadStorageProvider">
<providers>
<add name="FilesystemUploadStorageProvider" type="Brettle.Web.NeatUpload.FilesystemUploadStorageProvider, Brettle.Web.NeatUpload" />
</providers>
</neatUpload>

在<configuration>里面的后面位置加入
[复制此代码]CODE:
<location path="Default.aspx" >
<system.web>
<neatUpload useHttpModule="true" />
<httpRuntime maxRequestLength="2097151" executionTimeout="3600" useFullyQualifiedRedirectUrl="true" />
</system.web>
</location>
</configuration>
