想要在我的按钮点击事件上上传多个文件 [英] Want ajax multiple file upload on my button click event

问题描述

这是我的.aspx页码

Here is my .aspx page code

 <form id="form1" runat="server">
    <asp:ToolkitScriptManager runat="server">
    </asp:ToolkitScriptManager>
    <asp:AjaxFileUpload ID="AjaxFileUpload1" runat="server"
        Width="400px" OnUploadComplete="OnUploadComplete" Mode="Auto" />
    <asp:Button ID="abc" runat="server" Text="Button" OnClientClick="$('.ajax__fileupload_uploadbutton').trigger('click');" OnClick="abc_Click" />
</form>

.aspx.cs代码是

.aspx.cs code is

 protected void OnUploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
    {
        string fileName = Path.GetFileName(e.FileName);
        AjaxFileUpload1.SaveAs(Server.MapPath("~/uploads/" + fileName));
    }
    protected void abc_Click(object sender, EventArgs e)
    {
    // need file upload on this click and also need to store some outer data in this click event
    }

如何在我自己的按钮点击事件上实现ajax多文件上传我需要上传多个文件以及此按钮上的其他一些数据点击

我已经放置了控制html和.cs代码好吧，并使用事件OnUploadComplete上传多个图像，但我需要在abc_Click事件上传图像，以便单击我可以上传图像以及我也可以保存数据

推荐答案

您应该考虑将项目迁移到 ASP.NET MVC 。当向您的代码隐藏发送不同的和多种数据类型时，这会给您带来很多好处。然后你可以创建一个 ViewModel ，它可以保存图片列表以及你需要的其他信息，并在一次通话中将所有信息发送到你的后端。

You should really consider migrating the project to ASP.NET MVC. That would give you a lot of perks, when sending different and multiple data types to your code-behind. Then you can make a ViewModel which can hold a list of the pictures, alongside with the other information you need, and send all the information to your backend in one call.

当然，我不知道你是否已经熟悉MVC，但如果没有，
