Question

I have the follow line in my Javascript code

credenciadausuario = '<%= getCredenciada() %>';

In my code-behind I have this method

public string getCredenciada()
{
    Utilidade.QuebraToken tk = new Utilidade.QuebraToken();
    string credenciada = tk.CarregaToken(1, Request.Cookies["token"].Value);
    return credenciada;
}

but when I put the debugger in my javascript code, the credenciadausuario variable, receives the string “<%= getCredenciada() %>” and not the return of my method. How can I call my method that are in my code-behind via javascript or jquery ?

IF possible make use of ajax and do call the method, that will do you task.

Cs File (codebehind)

[WebMethod] 
public static string IsExists(string value) 
{     
    //code to check uniqe value call to database to check this     
   return "True";
 } 

Javascript

function IsExists(pagePath, dataString)
 {
  $.ajax({
     type:"POST",
     url: pagePath,
     data: dataString,
     contentType:"application/json; charset=utf-8",
     dataType:"json",
     error:
          function(XMLHttpRequest, textStatus, errorThrown) {               
               alert("Error");
          },
     success:
          function(result) {
                  alert( result.d);

      }
     }
});}

      var pagePath = window.location.pathname + "/IsExists";
     var dataString = "{ 'value':'ab" }";
     IsExists(pagePath, dataString);
