如何在视图中调用控制器动作方法,返回一个int值? [英] How do i call controller action method in view which returns a int value?
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("");
}
});
}
}
