How to create var in Javascript and access in MVC razor

Question

Javascript

 function Content(data) {
        var array = data.split(',');

    var id = array[0]; //I want to save this var and make it 
                       //accessible in the below razor code in the forloop. 
 }

@foreach (Chart item in Model)
 {
    @if(id -- this var is taken from the top javascript.) { 
        <tr>
           <td>                              
               @item.Description
           </td>
        </tr>
    } else { }
 }

As above I want to create a variable or some entity which is set in Javascript which can then be called in razor in the foreach loop.

Answer 2

Your can do it, only through ajax request.

in the client side use jQuery $.ajax

Controller:

[HttpPost]
        public void ActionName(bool id)
        {
    any actions
           ViewBag.id=id
           return View();
        }

in view:

@foreach (Chart item in Model)
 {
    @if(ViewBug.id) { 
        <tr>
           <td>                              
               @item.Description
           </td>
        </tr>
    } else { }
 }
