stringify

Here I'm creating a JavaScript object and converting it to a JSON string , but JSON.stringify returns "[object Object]" in this case, instead of displaying the contents of the object. How can I work around this problem, so that the JSON string actually contains the contents of the object? var theObject = {name:{firstName:"Mark", lastName:"Bob"}}; alert(JSON.stringify(theObject.toString())); //this alerts "[object Object]" Use alert(JSON.stringify(theObject)); theObject.toString() The .toString() method is culprit. Remove it; and the fiddle shall work: http://jsfiddle.net/XX2sB/1/ JSON

When stringifying an object using JSON.stringify (or something similar) is there a way to limit the stringification depth, i.e. only go n levels deep into the object tree and ignore everything that comes after that (or better: put placeholders in there, indicating something was left out)? I know that JSON.stringify takes a replacer function of the form function (key, value) but I didn't find a way to get the depth in the original object of the current key-value-pair handed to the replacer function. Is there a way to do this with the default JSON.stringify implementation? Or have I reached a

JavaScript Code: $.ajax({ type: "POST", url: "postTestingResult.php", data: {data: JSON.stringify(sendData)}, dataType: "json", success: ajaxSuccess, error: ajaxError }); PHP Code $data = json_decode($_POST['data'], TRUE); When I POST a complex data structure to the server, the outermost array is becoming a string. For example, the JavaScript object could be var data = {"apps": [[1,2,3], [4,5,6]]} Using JSON.stringify(data) this becomes "{"apps": "[[1,2,3], [4,5,6]]"}" //As seen via console.log(data) in Chrome console But after doing the json_decode($_POST['data'], TRUE) it becomes array('apps

I have the following JSON object data returned from my apicontroller : > [ {"id":2,"text":"PROGRAMME","parent":null}, > {"id":3,"text":"STAGE","parent":2}, > {"id":4,"text":"INFRA","parent":2}, > {"id":5,"text":"SYSTEM","parent":3}, > {"id":6,"text":"STOCK","parent":3}, {"id":7,"text":"DPT","parent":3}, > {"id":9,"text":"EXTERNAL","parent":null} ] I want to replace "parent":null with "parent":'"#"' I have tried the code below, but it is only replacing the first occurrence of "parent":null . How can I replace all "parent":null entries? <script> $(document).ready(function () { $.ajax({ url:

Why doesn't JSON.stringify() display prop2? var newObj = { prop1: true, prop2: function(){ return "hello"; }, prop3: false }; alert( JSON.stringify( newObj ) ); // prop2 appears to be missing alert( newObj.prop2() ); // prop2 returns "hello" for (var member in newObj) { alert( member + "=" + newObj[member] ); // shows prop1, prop2, prop3 } JSFIDDLE: http://jsfiddle.net/egret230/efGgT/ Eric Because JSON cannot store functions. According to the spec, a value must be one of: (source: json.org ) As a side note, this code will make the functions noticed by JSON.stringify : Function.prototype.toJSON
