JSON Web Service, Parameter Passing


Jennifer Mathews

The web service succesfully gets called if data: {} (no parameters)
But if I try to pass a parameter, an error occurs.
The Code Behind doesn't seem to like the parameter passing.

What am I doing wrong when passing the parameter?
I have tried:
//"{'fname':'dave'}" << doesnt work
//"{fname:dave}" << doesnt work
and actually a few others that I am too embarrassed to print.

type: "POST",
url: "wsLkup2_Load.asmx/Lkup2_Load",
data: {fname:dave}, << Error with ANY parameter. Works if just {} (no
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(result) {
error: function(req, status, error) {
alert('asdfasdf ERROR');

' if the parameter is removed, the web service is successfully called.
