Passing javascript object to webservice via Jquery ajax
- by kralco626
I have a webservice that returns an object
[WebMethod]
public List<User> ContractorApprovals()
I also have a webservice that accepcts an object
[WebMethod]
public bool SaveContractor(Object u)
When I make my webservice calls via Jquery:
function ServiceCall(method, parameters, onSucess, onFailure) {
var parms = "{" + (($.isArray(parameters)) ? parameters.join(',') : parameters) + "}"; // to json
$.ajax({
type: "POST",
url: "services/"+method,
data: parms,
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function(msg) {
if (typeof onSucess == 'function' || typeof onSucess == 'object')
onSucess(msg.d);
},
error: function(msg, err) {
$("#dialog-error").dialog('open');}
});
I can call the first one just fine. My onSucess function gets passed a javascript object exactly structured like my User object on the service.
However, I am now having trouble getting the object back to the server.
I'm accepting Object as a parameter on the server side so I can't inagine there is an issue there. So I'm thinking something is wrong with the parms on the client side but i'm not sure what...
I am doing something to the effect
ServiceCall("AuthorizationManagerWorkManagement.asmx/ContractorApprovals",
"",
function(data,args){$("#div").data('user',data[0])},
null)
then
ServiceCall("AuthorizationManagerWorkManagement.asmx/SaveContractor",
$("#div").data('user'), //These also do not work: "{'u': ' + $("#div").data("user") + '}", NOR JSON.stringify({u: userObject})
function(data,args){(alert(data)},
null)
I know the first service call works, I can get the data. The second one is causing the "onFailure" method to execute rather then "OnSuccess".
Any ideas?
