How to use "a.b()" with multiple instance of JSCocoaController?
benny
I'm trying to use JSCocoa in the iPhone. And the usage is like this;
============================================================
<Common.js>
function func_common()
{
log("Im func_common")
}
<Specifilc.js>
function test()
{
log("Im test - calling func_common with . notation")
theCommon.func_common();
}
============================================================
To make it work, I've tried to code like this
<xxxViewController.m>
- (IBAction) test_jscocoa
{
id jsCommon = [JSCocoaController sharedController];
id path = [[NSBundle mainBundle] pathForResource:@"Common"
ofType:@"js"];
[jsCommon evalJSFile:path];
//
id jsSpecific = [[JSCocoaController alloc] init];
id path2 = [[NSBundle mainBundle] pathForResource:@"Specific"
ofType:@"js"];
[jsSpecific evalJSFile:path2];
[jsSpecific setObject:jsCommon withName:@"theCommon"];
//
[jsSpecific callFunction:@"test"];
}
============================================================
But I got the error like this;
2011-03-18 10:59:48.500 SampleJSCocoa[671:207] Im test - calling
func_common with . notation
2011-03-18 10:59:48.501 SampleJSCocoa[671:207] JSException: TypeError:
Result of expression 'theCommon.func_common' [undefined] is not a
function. on line 17 of /Users/eshysis/Library/Application Support/
iPhone Simulator/4.2/Applications/514EC8B3-DF66-4D47-AFE7-ACE2C2A0546D/
SampleJSCocoa.app/Specific.js
============================================================
I think that the basic/critical problem is on 'setObject' method.
-> [jsSpecific setObject:jsCommon withName:@"theCommon"];
Which object should be setObject ?
ie. Some js files can be in defferent instance of JSCocoa . And one
instace of js wants to access them with . notation in the js file.
What should I do to make the '.' notation in a js file ?
Thanks in advance.
Benny.

Note that JSCocoa uses JavascriptCore, which is a private framework on the iPhone. The app store licenses prohibits this, your app might be rejected.

Patch JSCocoa to have it use an instance variable (add BOOL useAutoCall in JSCocoa's class definition in JSCocoaController.h) instead of the current global one.

Thank you for your response.

I want to keep the hope that JSCocoa will be allowed.
Anyway, do you have an alternative of JSCocoa?
btw,
is 'useAutoCall' in JSCocoaController.h.
It's hard to understand your recommendation to use 'a.b()' notation in
a js.
I think that I failed to explain my problem.
What I want is;
The usage "theCommon.func_common(); " is an obligation of mine. (not
'()', '.' is what I want)
The a.b() notation must be acceptable on my-building-app.
Can you advice to accomplish it?
Best Regards.

It seems that the . operation is working. No error!
But nothing happen!
That means 'theCommon.func_common' or 'theCommon.func_common()' does
not work.
Can you help this?
Best regards.

Since the license prohibits it, don't stake your app on it.

Someone suggested to bundle your own copy of JavascriptCore with your app. (Meaning downloading the Javascriptcore source, compiling it yourself, and including it as library in your project)
This would satisfy the app store requirement of "no private framework, no downloaded code".

[jsSpecific setUseAutoCall:NO];
This will apply to all jscocoa instances. If you want instance specific behaviour (what I understood from your first question), then you have to add an instance variable :
@interface JSCocoaController : NSObject {
JSGlobalContextRef ctx;
BOOL ownsContext;
id _delegate;
BOOL useAutoCall; // <----------------- add this for instance specific behaviour

Why do you want multiple instances in the first place ? Why jsCommon and jsSpecific ?

- Because of it's an necessity from my customers.
- They use .js files with such / these manners.
1. One .js has the codes and variables - it's called as Common or
Global js.
2. Other which is called as local js, calls the function of Common.
3. ie. "theCommon.function" calling method is used by my customer.
- I think that '.' operation is the solution.
- So still I'm looking for the How.
Dear author of "Multiple JSCocoa instances" in "parmanoir-
jscocoa-3008d25"
It does not run and not work.
Would you fix the problem of it?
I've tried to solve it like these;
1. 64bit -> 32 bit from "Get Info"
2. Add "jslint-jscocoa.js" into the project.
3. And move it to "Copy Bundle resource" from Targets.
Then it can be run. But does not work.
Another favor to Patrick.
Could I send my sample source to you to check up my problem?
Or where can I post my sample source to be check up?
Best regards

In this thread, there's such guide.
I can find some interesting apps which have a script-capable.
And I can get Opera browser in AppStore, also.
I think that we can publish our JSCocoa-apps.
Yours faithfully

Hi Benny,
I don't have time right now. Try to find a way to go with a single instance.

The app store accepts script libraries that are packaged in your app. Right now JSCocoa uses JavascriptCore which is private on the iPhone. If you want to bundle your own copy of JavascriptCore with your app, it might work. But once again, don't stake your app on it.
