问题描述

我从数据库中收集一个值。我希望将该值发送给view.and他们想检查该值。



我尝试过:



控制器中的操作方法

公共ActionResult BookSet(长?ClassId)

{

列表< bkselect> Bk =新列表< bkselect>();



Bk =(来自db.Student_Book_Allow_Quantity中的a

其中a.Class_Id == ClassId

选择新的BKselect()

{

Class_Id = a.Class_Id,

Student_Book_Allow_Quantity_Id = a.Student_Book_Allow_Quantity_Id

})。OrderBy(a => a.Class_Id).ToList();

ViewBag.BKselect = Bk.ToList();

返回PartialView();

}

视图部分

$(#FieldListTable)。append('

< input class =addNewButtonstyle =float:left; margin-left:0px;type =buttonvalue =Addid =btnAdd/>< input class =addNewButtonstyle =float:left; margin-left:0px;type =buttonid =btnRemovevalue =Remove/>
BOOkS LISt
@ Html.ListBox(LstSignInAuthority,Enumerable.Empty< SelectListItem>(),new {@id =LstSignInAuthority,style =width:200px; height: 130px;})
');

功能部分

功能Addbook(){

var bkLst = $(#LstSignInAuthority);

if(bkLst!==){

$(document).ready(function ()




var newValue = $('input [name = Book_Name]')。val();

var TotalItems = document.getElementById(LstSignInAuthor ity)。options.length;



if(TotalItems< 5){

$('#LstSignInAuthority')。append('< option value ='+ newValue +'>'+ newValue +'< / option>'); < br $>
$(#Book_Name)。val();

$(#Title)。val();

$(#Book_Category_Name)。val();



}



}) ;







}



}

I collecting a value from database. and i want to send that value to view.and their i want to check that value.

What I have tried:

In Action method in controller
public ActionResult BookSet(long? ClassId)
{
List<bkselect> Bk = new List<bkselect>();

Bk= (from a in db.Student_Book_Allow_Quantity
where a.Class_Id==ClassId
select new BKselect()
{
Class_Id=a.Class_Id,
Student_Book_Allow_Quantity_Id=a.Student_Book_Allow_Quantity_Id
}).OrderBy(a => a.Class_Id).ToList();
ViewBag.BKselect = Bk.ToList();
return PartialView();
}
in view part
$("#FieldListTable").append('

<input class="addNewButton" style="float: left; margin-left: 0px;" type="button" value="Add" id="btnAdd" /><input class="addNewButton" style="float: left; margin-left: 0px;" type="button" id="btnRemove" value="Remove" />
BOOkS LISt
@Html.ListBox("LstSignInAuthority", Enumerable.Empty<SelectListItem>(), new { @id = "LstSignInAuthority", style = "width:200px;height:130px;" })
');
fuction part
function Addbook() {
var bkLst = $("#LstSignInAuthority");
if (bkLst !== "") {
$(document).ready(function () {


var newValue = $('input[name=Book_Name]').val();
var TotalItems = document.getElementById("LstSignInAuthority").options.length;

if (TotalItems < 5) {
$('#LstSignInAuthority').append('<option value="' + newValue + '">' + newValue + '</option>');
$("#Book_Name").val("");
$("#Title").val("");
$("#Book_Category_Name").val("");

}

});



}

}

< input class =addNewButtonstyle = float:left; margin-left:0px;type =buttonvalue =Addid =btnAdd/>< input class =addNewButtonstyle =float:left; margin-left:0px ;type =buttonid =btnRemovevalue =Remove/>
BOOkS LISt
@ Html.ListBox(LstSignInAuthority,Enumerable.Empty< SelectListIt em>(),new {@id =LstSignInAuthority,style =width:200px; height:130px;})
');

@Html.ListBox("LstSignInAuthority", Enumerable.Empty<SelectListItem>(), new { @id = "LstSignInAuthority", style = "width:200px;height:130px;" })
');
fuction part
function Addbook() {
var bkLst =


(#LstSignInAuthority);

if(bkLst!==){
("#LstSignInAuthority");
if (bkLst !== "") {


(document).ready(function(){





var newValue =

var newValue =
