Ajax 如何将表单数据连同 ID 一起发送到 Controller

Question

I'm having a bit of trouble Sending the Form Data along with an ID to the controller. I'm getting the data to do with the file, just having trouble with the ID of event.target.id;.

Here is what I have below.

Ajax

var id = event.target.id;
                
var file = $("#" + event.target.id).prop("files")[0];
var formData = new FormData;
formData.append("file", file);formData.append("id",event.target.id);



                            $.ajax({
                                url: "@Url.Action("SaveImage")",
                                method: "post",
                                contentType: false,
                                processData: false,
                                data: formData,
                                success: function (booSession) {


                                }
                            });

Controller

[HttpPost]
    public ActionResult SaveImage()
    {var file = Request.Files[0];}

Thank you.

You need to add id as a parameter in the Action method.

I tested it with your code and its working for me

        [HttpPost]
        public ActionResult SaveImage(int id)
        { 
            var file = Request.Files[0];
