Look at below..
You can also acheive the same through below code..

JavaScript

"Salvar BD": function() {
$.ajax({
   type: "GET",
   //url: "../atualizaBD.aspx",
   //data: $("form").serialize(),
    url: "mainhomesearch.asmx/businesslisting",
   data: "{'keywords':'" + request.term + "','name':'Vinod','Email':'Vinodkumarnie@gmail.com','password':'******'}",
   cache: false,
   error: function(msg) { alert("Erro: " + msg); },
   success: function(msg) {
       alert("Ok!");
       allFields.val("");
   }
});

code below..
mainhomesearch.vb

C#

Public Function businesslisting(ByVal keywords As String, ByVal name As String, ByVal Email As String,ByVal Password As String ) As IList(Of String)

//your code here..

End Function

This is one way of passing more than one values and retrieve the same..

Solution 2

Use

C#

<webmethod> _

before writing function in codebehind.

since you are using
VB Use

VB

<webmethod> _

if c#

C#

[WebMethod]

Because json does not respond to normal function.

and change the url with calling the method name

url: "../atualizaBD.aspx/your function name",
