capture json value returned from controller into a variable in asp.net mvc view

Question

I'm developing an application using MVC/Jquery, i able to get a value from controller to view by below getJson code,

 $.getJSON('@Url.Action("SampleData", "Home")', { pageNum: 1, pageSize: PageSize, accountDetailsType: AccountDetailsType }, function (result) {
            //total number of records
            totalRecords = result.total;
            //total records
            records = result.data;

            $('#Description').val(result.reportType);

$('#Description') gives me desired data, which i can check by below textbox in view,

@Html.TextBox("Description")

now, question is, is there any way to put this value in any variable/hidden filed, so that base on that value..i can show/hide some control in my view...

similar like,

if(("Description") = "VB")
{
}
else
{

}

Do you want to access the same data which returned from getJSON ? you are already doing it using $("#Description"). Why do you want to copy the information in another variable/hidden field? — neeebzz

I don't see no need for putting the result into a hidden field. You can directly hide or show the affected controls in the callback function of your Ajax request:

$.getJSON('@Url.Action("SampleData", "Home")',
    { pageNum: 1, pageSize: PageSize, accountDetailsType: AccountDetailsType },
    function (result) {
        //total number of records
        totalRecords = result.total;
        //total records
        records = result.data;

        if (result.reportType == "VB") {
          $('#control1').hide();
          $('#control2').show();
        } else {
          $('#control1').show();
          $('#control2').hide();
        }
    });

+1 - bonus pointer, you can turn those 6 lines of hide/show into about 2 by using .toggle instead.

you have to change following line

@Html.TextBox("Description")

to

@Html.Hidden("Description")

you can set value of this hidden field like

$("#Description").val(result.reportType);

and read it like

var somevar = $("#Description").val(); //assign to variable or make comparisons
