问题描述
我的主页是这样的..
My Main Page Like this..
<body>
<form id="form1" runat="server">
<div style="width: 500px">
<div style="float:left;">
<iframe id="iFramImage" src="FileUploader.aspx" frameborder="0"></iframe>
</div>
<div style="float:right">
<asp:Image ID="imgUploaded" runat="server" AlternateText="Image" Height="400" Width="300"/>
</div>
</div>
<div>
<asp:Button ID="bntSaveImage" runat="server" Text="Save Image"
onclick="bntSaveImage_Click" />
</div>
</form>
</body>
FileUploader.aspx
FileUploader.aspx
<body>
<form id="form1" runat="server">
<div>
<asp:HiddenField ID="hdnImagFileName" runat="server" />
<asp:FileUpload ID="ImageUpload" runat="server"/>
</div>
</form>
</body>
FileUploader.aspx.cs
FileUploader.aspx.cs
public void FileUpload()
{
if (ImageUpload.HasFile)
{
if (CheckFileExtension(ImageUpload.FileName))
{
string filePath = "~/temp_image/" + ImageUpload.FileName;
ImageUpload.SaveAs(Server.MapPath(filePath));
}
}
hdnImagFileName.Value = ImageUpload.FileName;
}
protected bool CheckFileExtension(string FileName)
{
string ext = Path.GetExtension(FileName);
switch (ext.ToLower())
{
case ".jpg":
case ".png":
case ".bmp":
case ".gif":
return true;
default:
return false;
}
}
现在我想要的是使用时从我的
文件保存控制中选择一个图像文件
当时我在ifram的页面FileUploader.aspx中要调用FileUpload()，因此在该页面的哪个事件中我都将调用该函数，以便将我的文件上载到临时目录.
now what i want that when use select a image file from fileupload control held in my
ifram''s page FileUploader.aspx at that time i want to call FileUpload() so in which event of page i place that function call so my file will be uploaded at temp directory.
推荐答案
与JQuery无关.正如网上显示的众多示例所示，您将有一个按钮或其他控件来发起回发.从该事件中调用上载方法.
This has nothing to do with JQuery. As the multitude of examples available on the web show, you would have a button, or some other control to initiate the postback. Call the upload method from that event.
