问题描述

我在MVC5中工作,在项目文件夹上保存上传图像后,我想使用隐藏字段值将图像名称绑定到模型对象,



查看,



 @ Html.HiddenFor(m => m.AdImageFileName,new {@id =hdAdImageFileName})





我的尝试:



通过使用jQuery下面的代码,我保存图像并返回并将图像名称绑定到隐藏字段作为值。



 Advertisement = {
Addform: function (e){
this 。 SaveAdvtImages();
$ .ajax({
url: / UserRegister / Advertisement
类型: POST
data:$(' form')。serializeArray(),
success: function (结果){
$(' .loading')。hide( );
$( .modal-content)。height( 225 );
$(' #alertMsgModalContent')。html(result);
$(' #alertMsgModal')模态(选项);
$(' #alertMsgModal')。modal(' show');
},
错误:功能(结果){

}
});
},
SaveAdvtImages: function (){

var formData = new FormData($(' # frmAdvertisement')[ 0 ]);
$(' .loading')。show();
$ .ajax({
url:' ../ UserRegister / SaveAdvImages /'
类型:' POST'
data:formData,< span class =code-comment> //
{$ formData,pageVM:hidJson},

contentType: false
processData: false

成功: function (res){
$(' #hdAdImageFileName').val(res.AdvImage);
},
错误: function (数据){

}
});
}
}





但在提交'

 $之前( 'form')。serializeArray()

'我必须设置

 m => m.AdImageFileName 

模型对象。现在,

 [HttpPost] 
public ActionResult Advertisement(AdvertisementVM advertisementVM
{

}





 advertisementVM.AdImageFileName 

是传递null,不设置图像名称。



请帮帮我,我该怎么做?

解决方案

.ajax({
url: / UserRegister / Advertisement
类型: POST
data:


' form')。serializeArray(),
成功: function (result){


' .loading'< /跨度>)隐藏();

I am working in MVC5, After save the upload image on project folder then I want to bind the image name to model object using hidden field value,

View,

@Html.HiddenFor(m => m.AdImageFileName, new { @id = "hdAdImageFileName" })



What I have tried:

By using jQuery below code, I have saving image and return and bind the image name in to the Hidden field as value.

Advertisement = {
   Addform: function (e) {
    this.SaveAdvtImages();
                   $.ajax({
                       url: "/UserRegister/Advertisement",
                       type: "POST",
                       data: $('form').serializeArray(),
                       success: function (result) {
                           $('.loading').hide();
                           $(".modal-content").height(225);
                           $('#alertMsgModalContent').html(result);
                           $('#alertMsgModal').modal(options);
                           $('#alertMsgModal').modal('show');
                       },
                       error: function (result) {

                       }
                   });
                   },
   SaveAdvtImages: function () {

       var formData = new FormData($('#frmAdvertisement')[0]);
       $('.loading').show();
       $.ajax({
           url: '../UserRegister/SaveAdvImages/',
           type: 'POST',
           data: formData, //{ $formData, pageVM: hidJson },

           contentType: false,
           processData: false,

           success: function (res) {
               $('#hdAdImageFileName').val(res.AdvImage);
           },
           error: function (data) {

           }
       });
   }
   }



But before submit the '

$('form').serializeArray()

' I have to set

m => m.AdImageFileName

model object. Now,

 [HttpPost]
        public ActionResult Advertisement(AdvertisementVM advertisementVM
{

}



the

advertisementVM.AdImageFileName

is passing null, not setting image name.

Please help me, how can I do this ?

解决方案

.ajax({ url: "/UserRegister/Advertisement", type: "POST", data:


('form').serializeArray(), success: function (result) {


('.loading').hide();
