The tab character ( U+0009), carriage return ( U+000D), line feed ( U+000A), and space ( U+0020) characters are the only valid whitespace characters. Insignificant whitespace may be present anywhere except within a JSONNumber (numbers must contain no whitespace) or JSONString (where it is interpreted as the corresponding character in the string, or would cause an error). Date objects implement the toJSON () method which returns a string (the same as date.toISOString () ). Unescaped = %x20-21 / %x23-5B / %x5D-10FFFF JSON.stringify () calls toJSON with one parameter, the key, which has the same semantic as the key parameter of the replacer function: if JSON.stringify () was directly called on this object, an empty string. String = quotation-mark *char quotation-mark Object = begin-object Īrray = begin-array end-array
Value = false / null / true / object / array / number / string Valid JSON syntax is formally defined by the following grammar, expressed in ABNF, and copied from IETF JSON standard (RFC): JSON-text = object / arrayīegin-array = ws %x5B ws [ left square bracketīegin-object = ws %x7B ws right curly bracket For more information, see Object literal syntax vs. The same text may represent different values in JavaScript object literals vs. For those who wish to use a more human-friendly configuration format based on JSON, there is JSON5, used by the Babel compiler, and the more commonly used YAML. Here’s an example usage of JSON. It recursively converts all the enumerable properties of the object and their values into a string. Other differences include allowing only double-quoted strings and no support for undefined or comments. The JSON.stringify () method takes an object as an argument and returns a string that represents the object in JSON format. Before the revision, U+2028 LINE SEPARATOR and U+2029 PARAGRAPH SEPARATOR are allowed in string literals and property keys in JSON but the same use in JavaScript string literals is a Synta圎rror. NaN and Infinity are unsupported.Īny JSON text is a valid JavaScript expression, but only after the JSON superset revision. A decimal point must be followed by at least one digit. Property names must be double-quoted strings trailing commas are forbidden. It is based upon JavaScript syntax, but is distinct from JavaScript: most of JavaScript is not JSON. Keep in mind that I'm building an object or array of other objects here.JSON is a syntax for serializing objects, arrays, numbers, strings, booleans, and null. I have the same issue with the dynamic object every time. I've tried using an array of objects and that has the same issue.Īm I constructing my dynamic object wrong? I've tried building it with strings, pushing to an array, and several other things. However, the statically typed "hand made" JSON object using the same structure and keys and similar values does work properly. SP.UI.ModalDialog.showModalDialog(options) Īs you can see, the dynamically constructed JSON object shows up different in the console and will not stringify. console.log(JSON.parse(sessionStorage.getItem("labelData"))) tItem("labelData", JSON.stringify(labelData)) Ĭonsole.log("Compare Test Object Above to Dynamic Object Below") Url: "/Lists/Engineering Sample Database/SampleLabels.aspx" Var stringifyTest = JSON.stringify(stringifyTestObj) El método JSON.stringify()en Javascript se utiliza para crear una cadena JSON. LabelDataObject = labelDataTemp Ĭonsole.log("Test Statically Typed JSON Recursion") ġ: Var nextKey = Object.keys(labelDataObject).length+1
#STRINGIFY JSON JAVASCRIPT CODE#
Here's some of the code function parseSelectedItemsForLabels () I am trying to take selected listed items and pack specific data values from them into either an array or JSON "object" to then stringify and store in local browser session storage so I can pass it to a page for making labels for the selected list items.
