获取使用 ajax AsyncFileUpload 保存的文件的新文件名？

发布于 2024-10-08 04:50:13 字数 543 浏览 2 评论 0原文

我正在使用ajax工具包中的asyncfileupload ajax插件保存一个文件，当我保存它时，我正在更改文件名（以避免多个文件同名）。

文件上传后，用户需要知道文件的名称，因此我在 onclientuploadcomplete 事件中使用此 javascript 代码。

function UploadComplete(sender, args) {
    alert(args.get_fileName());
}

这是有效的，除非它获取的是旧名称，而不是新名称（由服务器端确定）。有什么办法让它返回新名称而不是旧名称？或者有什么办法可以实现这一目标？

这是我在获取新文件名后面的代码中的代码：

string filename = DateTime.Now.ToString("dMyHmsf") + e.filename;
string strPath = MapPath("~/SavedImages/") + filename;    
AsyncFileUpload1.SaveAs(strPath);

原文

I'm saving a file with the asyncfileupload ajax plugin from the ajax toolkit and when I save it I'm changing the filename (to avoid multiple files with the same name).

After the file is uploaded, the user needs to know what the file has been named so I'm using this javascript code on the onclientuploadcomplete event.

function UploadComplete(sender, args) {
    alert(args.get_fileName());
}

This works except it gets the old name, not the new name (which is determined server-side). Is there any way to get it to return the new name rather than the old name? Or any work around to achieve this?

This is my code in the code behind the get the new filename:

string filename = DateTime.Now.ToString("dMyHmsf") + e.filename;
string strPath = MapPath("~/SavedImages/") + filename;    
AsyncFileUpload1.SaveAs(strPath);

我从 http://forums.asp.net/post/4139037.aspx 它对我有用...

从那里复制代码：

<asp:ToolkitScriptManager runat="server">  
    </asp:ToolkitScriptManager>  


<!--This script snippet must be located below the ScriptManager-->  
    <script type="text/javascript">  
        Sys.Extended.UI.AsyncFileUpload.prototype.newFileName = null;  //I did not use this line
        function uploadcomplete(sender, e) {  
            alert(sender.newFileName);  
        }  
    </script>  


    <asp:AsyncFileUpload ID="AsyncFileUpload1" OnClientUploadComplete="uploadcomplete" 

        runat="server" OnUploadedComplete="AsyncFileUpload1_UploadedComplete1" />

背后的代码：

protected void AsyncFileUpload1_UploadedComplete1(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e) 
{ 
    ScriptManager.RegisterClientScriptBlock(this, 
        this.GetType(), "newfile",  
        "window.parent.$find('" + AsyncFileUpload1.ClientID + "').newFileName='newfile.jpg';", true); 
}

I got the answer from http://forums.asp.net/post/4139037.aspx It works for me...

copied code from there:

<asp:ToolkitScriptManager runat="server">  
    </asp:ToolkitScriptManager>  


<!--This script snippet must be located below the ScriptManager-->  
    <script type="text/javascript">  
        Sys.Extended.UI.AsyncFileUpload.prototype.newFileName = null;  //I did not use this line
        function uploadcomplete(sender, e) {  
            alert(sender.newFileName);  
        }  
    </script>  


    <asp:AsyncFileUpload ID="AsyncFileUpload1" OnClientUploadComplete="uploadcomplete" 

        runat="server" OnUploadedComplete="AsyncFileUpload1_UploadedComplete1" />

the code behind:

protected void AsyncFileUpload1_UploadedComplete1(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e) 
{ 
    ScriptManager.RegisterClientScriptBlock(this, 
        this.GetType(), "newfile",  
        "window.parent.$find('" + AsyncFileUpload1.ClientID + "').newFileName='newfile.jpg';", true); 
}
