And, to be JSON, all the quoted strings need to use "double quotes". The
JSON standard doesn't allow 'single quotes'.
The reason it hasn't caused any problem is that you're not using a JSON
parser to parse the JSON text, you're using eval(). And eval() of course
will accept (among other things) any JavaScript object literal.
Object literal notation allows either type of quote, and it makes the quotes
optional on property names as long as the name is a valid JavaScript
identifier. JSON is a subset of object literal notation and it is stricter
about the quotes.
Since you're using eval(), it doesn't really matter in a practical sense
whether you use strict JSON format or not. After all, even though we're
calling it "JSON", we're really using JavaScript code. You could even put
functions and stuff in there - download an object and the methods to go with
it.
You'll need to use the exact JSON format if you ever run your JSON data
through an actual JSON parser like the ones listed on json.org.
As an example, either of these would be valid JSON for your credits object:
{
"title": "credits",
"content": " <div
id=\"credits\"><h2>Credits</h2><div><p>Content</p></div></div>",
"image": "<img src=\"assets/images/scans/oink.jpg\" width=\"467\"
height=\"750\" alt=\"\" />",
"music": 8
}
or:
{
"title": "credits",
"content": " <div
id='credits'><h2>Credits</h2><div><p>Content</p></div></div>",
"image": "<img src='assets/images/scans/oink.jpg' width='467'
height='750' alt='' />",
"music": 8
}
Typically that would all be one one line with the extra whitespace removed,
but it's valid with or without the whitespace.
