Henrique Mendonca updated THRIFT-1087:
--------------------------------------
Attachment: THRIFT-1087-jquery-async-qunit.patch
THRIFT-1087-jquery-async-qunit.patch
Add support jQuery ajax for asynchronous requests:
{noformat}
client.testByte(0x01, function(result) {
equals(result, 0x01);
});
{noformat}
It uses a deferred object, so we can attach events like the normal jquery ajax
calls:
{noformat}
.error( function(error) { alert(error); } )
.success(function(result) {
alert("Success: " + result);
})
.complete(function() {
alert("complete");
})
{noformat}
I am not sure if we really need a separated generator (js:jquery) since it only
needs jQuery if the user adds a callback function to the parameter list.
e.g. *client.testByte(0x01)* still returns the result synchronously without
even using jQuery.
What do you guys think?

> The current js lib uses an ajax synchronous request, which is not very
> typical for javascript. Since the current browsers' js are still single
> threaded, they block the whole website until we get an answer from the server.
> Current trunk:
> {quote}
> MyServiceClient.prototype.getMyObject = function (objectId) \{
> this.send_getMyObject(objectId) //send request and wait for response
> return this.recv_getMyObject() //interpret response
> }
> {quote}
> I propose something like this: (pseudo-code + extra verbose for better
> understanding)
> {quote}
> MyServiceClient.prototype.getMyObject = function (objectId, onSuccessHandler)
> \{
> if ( ! onSucessHandler) \{
> this.send_getMyObject(objectId) //send request and wait for response
> return this.recv_getMyObject() //interpret response
> } else \{
> Thrift.HttpRequest.post( send_getMyObject(objectId) ); //send request
> asynchronously
> Thrift.HttpRequest.onreadystatechange = function () \{ onSuccessHandler(
> this.recv_getMyObject() ); } //call handler on success
> return Thrift.HttpRequest //return request object, as user might need
> to attach an onError handler
> }
> }
> {quote}
> I think it should be something similar to the jQuery post:
> http://api.jquery.com/jQuery.post/
> and it will still keep the compatibility with legacy code.
> Any thoughts or ideas?
