Passing variable from ASP.net to JavaScript

Question

How to pass a variable from asp.net to JavaScript?

Answer 1

1. Use javascript tag

   <script>
       var var1 = @var1;  
       var var2 = @var2;  
   </script>
   

2. Use hidden field

   <input type="hidden" value="@var1" id="h_var1"/>  
   <input type="hidden" value="@var2" id="h_var2" />`
   

in js

$(function()
{
    var var1 = $("#h_var1").val();
    var var2 = $("#h_var2").val();
}

3.Retrieve data via ajax using json

var var1;
var var2;
    $.get(url,function(result)
    {
        var1 = result.var1; var2 = result.var2;
     }

@var syntax depend of your view engine. It maybe <%= Var1 %>
