stringify

问题 I am storing some values in localStorage using stringify and I'm trying to parse them but it doesn't work for me. This is how I add the values: localStorage.setItem('a', JSON.stringify({ userid : '4361', value : '23' })); And this is how I parse them: $('p').text(JSON.parse(localStorage.getItem('a'))); Here is the fiddle: http://jsfiddle.net/hrHfG/ Also, I'd like to know how can I parse each value separately. For example, only the userid of 'a', or only the value, if its possible. Thanks a

问题 How can I stringify a preprocessor macro with GNU gfortran? I would like to pass a macro definition to GNU gfortran which will then be used as a string in the code. Effectively I would like to do this: program test implicit none character (len=:), allocatable :: astring astring = MYMACRO write (*, *) astring end program test and then build with: gfortran -DMYMACRO=hello test.F90 I tried creating various macro, for example: #define STRINGIFY_(x) #x #define STRINGIFY(x) STRINGIFY_(x) ...

问题 I want to give a simple true response, but according to various JSON parsers, this is not valid JSON: true However, PHP and Javascript act like "true" is indeed valid JSON for true , both when encoding and when decoding: PHP- echo json_encode( true ); // outputs: true echo json_decode( true ); // outputs: 1 echo gettype(json_decode( true )); // outputs: boolean jQuery- JSON.stringify( true ); // outputs: true jQuery.parseJSON( true ); // outputs: true typeof jQuery.parseJSON( true ); //

问题 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/ 回答1: Because JSON cannot store functions. According to the spec, a value must be one of: (source: json.org)

问题 EDIT: Something like this, but this is not working either, but there is the problem I think var stringifyObj = JSON.stringify({ "addressAddressId":$('#address').val(){ "cityId:"$('#city').val(){ "postalCode":$('#postalCode').val() } } }); * When I generate test client in Netbeans, JSON-structure (GET/JSON) is like that, but how can I code that with Javascipt and Strinfy-function? * "addressAddressId": { "addressId": 1, "address": "Järnvägen 2", "address2": null, "district": null, "postalCode"

问题 I am running the following piece of code: var arr = []; arr["aaa"] = { "xxx" : 1, "ttt" : 2 }; arr["bbb"] = { "xxx" : 5, "qqq" : 6 }; var tmp = JSON.stringify(arr); alert(tmp); But the result is [] . How does one stringify an array with string keys and object values? 回答1: Use var arr = {}; Arrays should only be used for numerically indexed data, not arbitrary properties. Of course you are able to do it, because they are, in fact, objects. But it won't work in JSON. Instead, just use objects.

问题 I'm trying to stringify objects in Typescript that was implemented usign private properties like this export class Foo { private _property1:string; private _property2:string; private _property3:string; get property1(): string { return this._property1; } set property1(value: string) { this._property1 = value; } get property2(): string { return this._property2; } set property2(value: string) { this._property2 = value; } get property3(): string { return this._property3; } set property3(value:

问题 @SOLVED As explained by James M. Lay, I should change my content-type from application/x-www-form-urlencoded to application/json it implied in an error because it seems that only UrlEnconded types generates POST arrays in server side (at least in PHP). So I had to change the way I receive/deal with the request in my server script $json = file_get_contents('php://input'); //yes. php://input if($json) $params = json_decode($json,true); else $params = $_POST; I also had to make a few changes in
