I'm creating a JSON string and passing it to a SCORM 1.2 compliant LMS thus:
var tmp = {};
tmp.assess = assessScore;
tmp.loc = location;
tmp.progress = notes.topics.to String();
fScormSetValue( "cmi.suspend_da ta", tmp.toJSONStrin g(), false);
alas the LMS complains with this error
Error: missing ; before statement
Line: 1104, Column: 35
Source Code:
this.cmi.suspen d_data.cmivalue
= "{"assess":{"0_ 1q":true},"loc" :"res_0_2.htm", "progress":"1"} ";
------^
Ok, the LMS sees the JSON string as more than one string. I can, though,
successfully read and write it to a cookie.
I'm not sure what's going on. How do I resolve this?

The first guess would that your problem is a quoting issue where it is
seeing the "{" and then assess and balking on the quotes. Try changing
the outer quotes to ' and see if it makes a difference.
this.cmi.suspen d_data.cmivalue ='{"assess":{"0 _1q":true},"loc ":"res_0_2.htm" ,"progress":"1" }';

The error is being produced/reported by the LMS and is not something I

cmi.suspendata with the value tmp.toJSONStrin g().

Then you either have to use ' in your value, escape it in your value, or
encode it.

Then you either have to use ' in your value, escape it in your value, or

If I first convert apostrophes to ' and then quote to apostrophes
the LMS doesn't complain:
var tmp = {};
tmp.assess = assessScore;
tmp.loc = location;
tmp.progress = notes.topics.to String();
var str = tmp.toJSONStrin g();
str = str.replace(/'/g, "'");
str = str.replace(/\"/g, "'");
fScormSetValue( "cmi.suspend_da ta", str, false);
When I read back the value I reverse the process. It seems to be
working. Is this the "best" way to do it?

Without knowing how the LMS works, nobody can tell you what way would be
"best". The only thing you can do is try different ways and see which
ones don't fail. If it isn't broke, don't fix it though :)

Alas the LMS is a 3rd party product and so not open to inspection.

PS i am ready to use JSON as data/object interchange when using AJAX

Hello,
I noticed that the JavaScript library for JSON posted on json.org
(http://www.json.org/json.js) is modifying Object.prototype (adding a
method - toJSONString). I thought this was considered bad practice
because it can disrupt the use of for in loops on Objects.
Am I incorrect?

JSON vs. XML
JSON and XML are basically used for the same purpose—to represent and interchange data. I'll try to show you why you might want to use JSON rather than XML in an AJAX context by showing you an example of how an data class (actually, a list of PHP documentation pages) might be represented, first in XML. and then in JSON. This side-by-side comparison should let you begin to understand how to represent data in JSON. The XML version:...
