Question

I have a simple jQuery AJAX method that send data to a web method which brings data from da database. When I send number it works properly but I don’t know how to send data with parameter.

For example this method works properly:

function catchdata() {
     $.ajax({
         type: "POST",
         url: "rank.aspx/bringdata",
         data: "{lmt:16}",
         contentType: "application/json; charset=utf-8",
         dataType: "json",
         async: true,
         cache: false,
         success: function(ret){
             s = ret.d;
             dos(s, 0);
         },
         error: function(x,e){
             alert("error occur");
         } 
     });
}

But this below code does not work and error function raise:

function catchdata() {
     $.ajax({
         type: "POST",
         url: "rank.aspx/bringdata",
         data: {
             lmt:total
         },
         async: true,
         cache: false,
         success: function(ret){
             s = ret.d;
             dos(s, 0);
         },
         error: function(x,e){
             alert("error occur");
         }
     });
}

Answer 1

If the first example works fine, this should do the same with a parameter: (I assume total is defined as global variable elsewhere)

$.ajax({
     type: "POST",
     url: "rank.aspx/bringdata",
     data: "{lmt:" + total + "}",
     contentType: "application/json; charset=utf-8",
     dataType: "json",
     async: true,
     cache: false,
     success: function(ret){
         s = ret.d;
         dos(s, 0);
     },
     error: function(x,e){
         alert("error occur");
     } 
 });
