I wanted to stringify an object on the first level without including a third-party library / too much code. In case you look for the same, here is a quick one-liner to do so: var json = JSON.stringify(obj, function (k, v) { return k && v && typeof v !== “number” ? (Array.isArray(v) ? “[object … Read more

When you save some data using JSON.stringify() and then need to read that in php. The following code worked for me. json_decode( html_entity_decode( stripslashes ($jsonString ) ) ); Thanks to @Thisguyhastwothumbs
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
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
Use the second parameter of stringify, the replacer function, to exclude already serialized objects: var seen = []; JSON.stringify(obj, function(key, val) { if (val != null && typeof val == “object”) { if (seen.indexOf(val) >= 0) { return; } seen.push(val); } return val; }); http://jsfiddle.net/mH6cJ/38/ As correctly pointed out in other comments, this code removes … Read more
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>
