If an object you export as CSV with Export-Csv or ConvertTo-Csv has property values that contain a collection (array) of values, these values are stringified via their .ToString() method, which results in an unhelpful representation, as in the case of your array-valued .IPV4Addresses property. To demonstrate this with the ConvertTo-Csv cmdlet (which works analogously to … Read more
JSON.stringify includes an object’s own, enumerable properties (spec) that have values that aren’t functions or undefined (as JSON doesn’t have those), leaving out ones it inherits from its prototype, any that are defined as non-enumerable, and any whose value is a function reference or undefined. So clearly, the object you get back from getVoices()[0] has … Read more
Like the other answers stated, Infinity is not part of the values JSON can store as value. You can reverse the censor method on parsing the JSON: var c = JSON.parse(b, function (key, value) { return value === “Infinity” ? Infinity : value; });
Please use a <pre> tag demo : http://jsfiddle.net/K83cK/ var data = { “data”: { “x”: “1”, “y”: “1”, “url”: “http://url.com” }, “event”: “start”, “show”: 1, “id”: 50 } document.getElementById(“json”).textContent = JSON.stringify(data, undefined, 2); <pre id=”json”></pre>
You can use JSON.stringify with a replacer like: JSON.stringify({ color: ‘red’, doSomething: function (arg) { alert(‘Do someting called with ‘ + arg); } }, function(key, val) { return (typeof val === ‘function’) ? ” + val : val; });
You can use toJSON method to customise the way your class serialises to JSON: class MyClass { constructor(property) { this.property = property } set property(prop) { // Some validation etc. this._property = prop } get property() { return this._property } toJSON() { return { property: this.property } } }
I did what I initially feared I’ll have to do : I took Crockford’s code and modified it for my needs. Now it builds JSON but handles cycles too deep objects too long arrays exceptions (accessors that can’t legally be accessed) In case anybody needs it, I made a GitHub repository : JSON.prune on GitHub … Read more
I’m not entirely sure but I think you are probably surprised at how arrays are serialized in JSON. Let’s isolate the problem. Consider following code: var display = Array(); display[0] = “none”; display[1] = “block”; display[2] = “none”; console.log( JSON.stringify(display) ); This will print: [“none”,”block”,”none”] This is how JSON actually serializes array. However what you … Read more
You won’t be able to serialize an event object with JSON.stringify, because an event object contains references to DOM nodes, and the DOM has circular references all over the place (e.g. child/parent relationships). JSON can’t handle these by default, so you’re a bit out of luck there. I’d suggest to look at How to serialize … Read more
Circular structure error occurs when you have a property of the object which is the object itself directly (a -> a) or indirectly (a -> b -> a). To avoid the error message, tell JSON.stringify what to do when it encounters a circular reference. For example, if you have a person pointing to another person … Read more
