ajax success/error handlers

[devrow]

hi.
something is wrong...
(for all requests server status is 200)

var client = new $.RestClient('/rest/api/', { stringifyData: true });
restAjaxOptions = {
    success: function(data, textStatus, jqXHR) {
       console.log("success " + jqXHR);
    },
    error: function(jqXHR, textStatus, errorThrown) {
       console.log("error " + jqXHR);
    }
};
client.add('items', {ajax: restAjaxOptions});
...
$("button[data-role='save']").on("click", function(e){
  client.items.update($("#form").serializeJSON());
});

console log:

success [object]

var client = new $.RestClient('/rest/api/', { stringifyData: true });
restAjaxOptions = {
    success: function(data, textStatus, jqXHR) {
       console.log('success ' + jqXHR);
    },
    error: function(jqXHR, textStatus, errorThrown) {
       console.log('error ' + jqXHR);
    }
};
client.add('items');
...
$("button[data-role='save']").on("click", function(e){
  client.items.update($("#form").serializeJSON(), {ajax: restAjaxOptions});
});

console log:

success undefined
error undefined

how can i pass the error handlers for each resource request?
thx.

Do you want handlers that run for all requests under one resource? or do you want handlers for one particular request?

[devrow]

for one particular request. mainly for update resource requests. but for GET method i want handle internal server side script errors contains in data argument.

for example:

restAjaxOptions = {
    success: function(data, textStatus, jqXHR) {
       if (data.rc == -1) {
           alert("data too big");
       } else {
           // bla-bla-bla
       }
    },
//...
};

maybe there is another way?

So update(id1, id2, idN, data) only accepts IDs (to build the URL) and the POST/PUT body, though it returns a deferred object (a jquery promise). So what you want is:

client.foo.update({test:42}).done(successHandler);
client.foo.update({test:42}).fail(errorHandler);
//where errorHandler is function(xhr, result, statusText){...}

ok. thank you. 👍
i casually read the manual.
