How can I use jquery remote validation validation in ASP.NET web forms?

Question

I have searched everywhere and I cannot find a convincing example.

Does anyone do this? Can someone provide an example of invoking remote validation using the JQuery validation plugin via WebMethod on an aspx page (web forms)?

Answer 1

I think the reason that the code gives you a bad taste is because writing json as strings is pretty smelly. One minor improvement would be to create a real JSON object and then use the JSON.stringify (...) function.

json-,

var customerInput = {"customerToAssignTo":$("#customerToAssignTo").val()};
var serializedCustomerInput = JSON.stringify(customerInput );

data: "{'customerToAssignTo':'" + $("#customerToAssignTo").val() + "'}"

data: serializedCustomerInput
