Asynchronous Javascript problem

Hi,
I'm working on an app which has a google map which users can use to
search for locations, and on which I want to place markers.
The asynchronous call is a call to google's geocoder service which
takes a string to search for from an input field, and a callback
function that the position will be passed to:
geocoder.getLatLng(address,showAddress);
function showAddress(point) {
if (!point) {
alert(address + " not found");
} else {
map.setCenter(point, 13);
}
}
So the issue here is that after map.setCenter I want to make an ajax
call to retrieve marker data from the server using the 'point'. I
would like to use lift's javascript abstraction to build this but I'm
struggling to see how to do it given the asynchronous call.
Any ideas?

You can put a little JavaScript on the page which contains a function that you can call... for example:
define a JsonHandler:
Now, build a stable function to send to the browser:
You'll have a JavaScript function, sendPointToServer that you cal with the point and the rest is automatic.
Thanks,

define a JsonHandler:

def apply(in: Any): JsCmd = in match {
case JsonCmd("setPoint", _, yourData, _) =>
/// do something with yourData
Noop
}
}
def apply(in: Any): JsCmd = in match {
case JsonCmd("setPoint", _, yourData, _) =>

}
Now, build a stable function to send to the browser:
Script(Function("sendPointToServer", "point", PointHandler.call("setPoint", JsVal("point"))))
You'll have a JavaScript function, sendPointToServer that you cal with the point and the rest is automatic.

Hi,
I had to replace JsVal("point") with JsVar("point"), but when I run it
up, I get "ReferenceError: Can't find variable: F542198622797IUJ" in
the browser console. The function in the page looks like this:
function sendPointToServer(point) {
F542198622797IUJ({'command': 'setPoint', 'params':point});
}
I guess I am missing something else?

Are you putting the result of:
Script(Function("sendPointToServer", "point", PointHandler.call("setPoint", JsVal("point"))))
Anywhere on your page?

which looks like this:
def mapFunctions(xhtml : NodeSeq) : NodeSeq = {
val node = Script(Function("sendPointToServer", List("point"),

node ++ <head>{Script(OnLoad(Call("initialize")))}</head>

cool thanks, that did it.
Google recommends running a script on unload, their example has: <body
onload="initialize()" onunload="GUnload()">
I couldn't see any Unload function anyway, I guess it would be a
useful thing to add?

ok I am getting somewhere. Thanks for your patience, I'll write this
up somewhere in case someone else needs a google map in a liftweb app.
The functions being generated are good:
function sendPointToServer(point) {
F298945645192D4K({'command': 'setPoint', 'params':point});
}
function F298945645192D4K(obj) {lift_ajaxHandler('F298945645192D4K='+
encodeURIComponent(JSON.stringify(obj)), null,null);
But I get a "Can't find variable: JSON" error.

But the problem I am having now is a NumberFormatException:

The string its parsing is: {"command":"setPoint","params":{"mf":
51.3256123,"$a":-0.6379592,"x":-0.6379592,"y":51.3256123}}
The scala json parser seems ok with it though.

Channing,
We don't use the Scala JSON parsing stuff because it does not do well with very long JSON expressions (stack overflow problems).
The parsing defects (which I've fixed and added tests for) are a result of some strong typing that Scala *should* be enforcing and is not (the compiler was not rejecting certain patterns which should never have been allowed.)
Give it an hour and give it a try.
Thanks for hanging with me through these defects.

This is very odd because the very data set that you included is part of the tests for the JSON parser.
Please delete ~/.m2/respository and do a clean build and see if it works.

ah wait, I am not seeing the latest code changes you made in the
snapshot source I just downloaded from the mvn repos. I will endeavour
to figure out why.

spoke too soon :-(
when I test this on a new browser or flush browser caches, I am
getting a javascript error: Undefined variable: JSON
I am not wrapping my the input field in a json form as described in
the book because when I do the page reloads. Could that be the
problem? In which case how do I prevent the page reloading?

ok, lots of jscript debugging and I'm pretty sure its this:
JSON.stringify(new GLatLng(0,0))
where GLatLng is a google map object.
the imports needed for this are
<script src="http://maps.google.com/maps?
file=api&v=2.x&key=your-key&sensor=false" type="text/
javascript"></script>
<script type="text/javascript" src="/classpath/jquery.js"
id="jquery"></script>
<script src="/classpath/json.js" type="text/javascript"></script>
there is a key=your-key argument in that first import. don't worry
about that, just make sure you test the page using localhost, not
127.0.0.1, just localhost. The key is not used for file:// and
localhost addresses.

actually that example doesn't work in Opera, but does in safari and
firefox. To see the problem in safari I had to modify the script like
this:
var geocoder = new GClientGeocoder();
geocoder.getLatLng("london",doit);
function doit(point) {
var s = JSON.stringify(point);
alert(s)
}
This does work in Firefox though, but my full version doesn't.
Hopefully these examples will help a little. I am beginning to think I
should just pass simple objects to the server via JSON.

In order to debug the problem, I need something that is fully running (e.g., fork http://github.com/dpp/lift_1_1_sample/tree/master and implement something that demonstrates the problem).
The mechanism we are working on is passing the objects to the server via JSON. JSON.stringify is the JSON serializer and an JavaScript object must be serialized to send to the server.

ok I've done that: git://github.com/channingwalton/lift_1_1_sample.git
run the app up and go to http://localhost:8080/mapSearch and try the
search. I find stack overflow in Safari 4.0.2, and Opera 9.64. The
query works in Firefox 3.5.2 and Webkit Version 4.0.2 (5530.19,
r46770) (latest nightly) - all OS X
I haven't been able to test on windows yet.

I've added a much simpler example too, see simple.html

I reproduced the issue on Opera... then Google banned my IP address for excessive requests... :-(
I'll sign up for a google maps account.
