[jQuery] ArgumentOutOfRange Exception

[jQuery] ArgumentOutOfRange Exception


Hi, All
I use jquery 1.2.6 in one of my projects and it will call some
webmethods without arguments. it works properly in my dev machine.
However, ArgumentOutOfRange Exception (parameter: length) will be
thrown after deployment. Any idea? Thanks in advance.
Snippet like:
$.ajax({
type: "POST",
url: "Mywebpage/Mywebmethod",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(result) {
....
}
});
