	17	+ NOT CONTROL.
	18	+
	19	+
	20	+ This file creates a global JSON object containing two methods: stringify
	21	+ and parse.
	22	+
	23	+ JSON.stringify(value, replacer, space)
	24	+ value any JavaScript value, usually an object or array.
	25	+
	26	+ replacer an optional parameter that determines how object
	27	+ values are stringified for objects. It can be a
	28	+ function or an array of strings.
	29	+
	30	+ space an optional parameter that specifies the indentation
	31	+ of nested structures. If it is omitted, the text will
	32	+ be packed without extra whitespace. If it is a number,
	33	+ it will specify the number of spaces to indent at each
	34	+ level. If it is a string (such as '\t' or ' '),
	35	+ it contains the characters used to indent at each level.
	36	+
	37	+ This method produces a JSON text from a JavaScript value.
	38	+
	39	+ When an object value is found, if the object contains a toJSON
	40	+ method, its toJSON method will be called and the result will be
	41	+ stringified. A toJSON method does not serialize: it returns the
	42	+ value represented by the name/value pair that should be serialized,
	43	+ or undefined if nothing should be serialized. The toJSON method
	44	+ will be passed the key associated with the value, and this will be
	45	+ bound to the value
	46	+
	47	+ For example, this would serialize Dates as ISO strings.
	48	+
	49	+ Date.prototype.toJSON = function (key) {
	50	+ function f(n) {
	51	+ // Format integers to have at least two digits.
	52	+ return n < 10 ? '0' + n : n;
	53	+ }
	54	+
	55	+ return this.getUTCFullYear() + '-' +
	56	+ f(this.getUTCMonth() + 1) + '-' +
	57	+ f(this.getUTCDate()) + 'T' +
	58	+ f(this.getUTCHours()) + ':' +
	59	+ f(this.getUTCMinutes()) + ':' +
	60	+ f(this.getUTCSeconds()) + 'Z';
	61	+ };
	62	+
	63	+ You can provide an optional replacer method. It will be passed the
	64	+ key and value of each member, with this bound to the containing
	65	+ object. The value that is returned from your method will be
	66	+ serialized. If your method returns undefined, then the member will
	67	+ be excluded from the serialization.
	68	+
	69	+ If the replacer parameter is an array of strings, then it will be
	70	+ used to select the members to be serialized. It filters the results
	71	+ such that only members with keys listed in the replacer array are
	72	+ stringified.
	73	+
	74	+ Values that do not have JSON representations, such as undefined or
	75	+ functions, will not be serialized. Such values in objects will be
	76	+ dropped; in arrays they will be replaced with null. You can use
	77	+ a replacer function to replace those with JSON values.
	78	+ JSON.stringify(undefined) returns undefined.
	79	+
	80	+ The optional space parameter produces a stringification of the
	81	+ value that is filled with line breaks and indentation to make it
	82	+ easier to read.
	83	+
	84	+ If the space parameter is a non-empty string, then that string will
	85	+ be used for indentation. If the space parameter is a number, then
	86	+ the indentation will be that many spaces.
	87	+
	88	+ Example:
	89	+
	90	+ text = JSON.stringify(['e', {pluribus: 'unum'}]);
	91	+ // text is '["e",{"pluribus":"unum"}]'
	92	+
	93	+
	94	+ text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
	95	+ // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
	96	+
	97	+ text = JSON.stringify([new Date()], function (key, value) {
	98	+ return this[key] instanceof Date ?
	99	+ 'Date(' + this[key] + ')' : value;
	100	+ });
	101	+ // text is '["Date(---current time---)"]'
	102	+
	103	+
	104	+ JSON.parse(text, reviver)
	105	+ This method parses a JSON text to produce an object or array.

	115	+
	116	+ // Parse the text. Values that look like ISO date strings will
	117	+ // be converted to Date objects.
	118	+
	119	+ myData = JSON.parse(text, function (key, value) {

Use $article = new Article( $form, 0 );. This thing has caused enough bugs already.

#Comment by Werdna (talk | contribs) 02:56, 21 May 2011

Not sure I understand.

#Comment by Nikerabbit (talk | contribs) 06:38, 21 May 2011

What can I do?

#Comment by Catrope (talk | contribs) 10:37, 21 May 2011

If you don't pass zero as the second parameter to the Article constructor, it'll try to infer the oldid from $wgRequest, which will happily override the provided title if the oldid in the query string refers to a different title.

#Comment by MZMcBride (talk | contribs) 03:12, 21 May 2011

Where'd this code come from? It doesn't seem to be following the standard extension file layout.

#Comment by 😂 (talk | contribs) 03:16, 21 May 2011

Looks fine to me, other than Body.php.

#Comment by MZMcBride (talk | contribs) 03:18, 21 May 2011

Yeah, the more I looked, I guess it's not so strange. The lack of a i18n file, the "Body.php" file name, and the lack of a url/version in the ExtensionCredits made me think he might've been importing someone else's code into SVN. Guess not.

Hi,

Did you make any changes to the original json2.js code that made ext.sftoolbar.json specific to the SemanticFormsToolbar extension? if not, please rename to jquery.json (if you need backwards compatibility) or remove it and use the jquery.json.js already in /phase3/resources/jquery/ :).
