Hey guys,

This is just a question that I've been trying to find some information on and can't seem to locate it anywhere. I want to be able to call a service using code service.execute({});/code, but I want to be able to manipulate some of the callbacks from the javascript code. I found that we can do this:
pre
service.execute({
success: function(e) {
//Success handler here
},
error: function(e) {
//Error handler here
},
complete: function(e) {
//Complete handler here
},
});
/pre

but I've also seen Yurii post this notation:

pre
uploadService2.execute({
'allowDataModification': false,
'processData': false,
'body': {data: data},
'cache': false,
'success': onSuccess
});
/pre

I have 3 questions:
1- Should the success be in quotes, as shown in Yurii's response, or not, as in the previous one?
2- What would we use for the "Before Send" handler?
3- How would we set the data mapping from this javascript?

I've looked at the documentation here, but there is no information on how to create a code snippet that is equivalent to using the Appery's mapping feature (maybe it's just the same as code"body"{data:data}/code?), and no information on setting the "Before Send" handler function.

Hello,

1) No, it shouldn't be in quotes
2) You have to add "data" parameter, which send request parameters. It is the same as "before send" event: https://getsatisfaction.com/apperyio/...
3) You have to use one of two variants: mapping or execution JS.

Thank you Sergiy for the response. Just to clarify:

1. Great, that's clear.

2. Is there an example where someone used the "data" parameter (just to see what the code should look like)? I can't find anything in the documentation either. Or would it simply be like:
   pre
   service.execute({
   data: function(e){
   //Before Send handler here
   },
   success: function(e) {
   //Success handler here
   },
   error: function(e) {
   //Error handler here
   },
   complete: function(e) {
   //Complete handler here
   },
   });
   /pre

3. Lastly, I know we can use the mapping functionality, but I would like to know HOW to do the JS execution of the mapping. Is there a sample code for this? In other words, if I have a service that looks like:
   
   As an example, how would we create the equivalent using:
   pre
   restservice1.execute({
   data: function(e){//is the use of "data" correct here?
   /What is the JS execution for mapping here, if suppose we are mapping a LSV named "UserName" to the request parameter "username"?/
   },
   success: function(e) {
   /What is the JS execution for mapping here, if suppose we are mapping the response parameter "Status" to the LSV named "userStatus"?/
   },
   error: function(e) {
   //Error handler here
   }
   });
   /pre

   Thank you again for the clarification and reference!

I think I got it. I created a simple server code script, added it as a service, and created No mapping and no javascript where the service was added to the page. Then when I call for the execution of the service, I define the "data" mapping, as well as what it should do on success and on error. Here's my example:

pre
function testButtonClick(){
var onSuccessHandler = function(data){if(data){alert(data.replied);}};
var onErrorHandler = function(data){if(data){alert(JSON.stringify(data));}};
sentReplied.execute({
data:{"sent":localStorage.getItem("username")},
success:onSuccessHandler,
error: onErrorHandler
});
}
/pre

And it works great.

Thanks again Sergiy for the help.

Thanks for the update, Jon!
