Pour construire sur stewe réponse de la fermeture du compilateur avec l' Avancée activée vous donne un script qui pollue l'espace de noms global avec un groupe d'une lettre de variables. Alors, je viens de l'envelopper dans un anonyme, un appel de fonction comme ceci:
(function() {
function g(a){var b=typeof a;if("object"==b)if(a){if(a instanceof Array)return"array";if(a instanceof Object)return b;var c=Object.prototype.toString.call(a);if("[object Window]"==c)return"object";if("[object Array]"==c||"number"==typeof a.length&&"undefined"!=typeof a.splice&&"undefined"!=typeof a.propertyIsEnumerable&&!a.propertyIsEnumerable("splice"))return"array";if("[object Function]"==c||"undefined"!=typeof a.call&&"undefined"!=typeof a.propertyIsEnumerable&&!a.propertyIsEnumerable("call"))return"function"}else return"null";
else if("function"==b&&"undefined"==typeof a.call)return"object";return b};function h(a){a=""+a;if(/^\s*$/.test(a)?0:/^[\],:{}\s\u2028\u2029]*$/.test(a.replace(/\\["\\\/bfnrtu]/g,"@").replace(/"[^"\\\n\r\u2028\u2029\x00-\x08\x10-\x1f\x80-\x9f]*"|true|false|null|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?/g,"]").replace(/(?:^|:|,)(?:[\s\u2028\u2029]*\[)+/g,"")))try{return eval("("+a+")")}catch(b){}throw Error("Invalid JSON string: "+a);}function i(a,b){var c=[];j(new k(b),a,c);return c.join("")}function k(a){this.a=a}
function j(a,b,c){switch(typeof b){case "string":l(b,c);break;case "number":c.push(isFinite(b)&&!isNaN(b)?b:"null");break;case "boolean":c.push(b);break;case "undefined":c.push("null");break;case "object":if(null==b){c.push("null");break}if("array"==g(b)){var f=b.length;c.push("[");for(var d="",e=0;e<f;e++)c.push(d),d=b[e],j(a,a.a?a.a.call(b,""+e,d):d,c),d=",";c.push("]");break}c.push("{");f="";for(e in b)Object.prototype.hasOwnProperty.call(b,e)&&(d=b[e],"function"!=typeof d&&(c.push(f),l(e,c),c.push(":"),
j(a,a.a?a.a.call(b,e,d):d,c),f=","));c.push("}");break;case "function":break;default:throw Error("Unknown type: "+typeof b);}}var m={'"':'\\"',"\\":"\\\\","/":"\\/","\u0008":"\\b","\u000c":"\\f","\n":"\\n","\r":"\\r","\t":"\\t","\x0B":"\\u000b"},n=/\uffff/.test("\uffff")?/[\\\"\x00-\x1f\x7f-\uffff]/g:/[\\\"\x00-\x1f\x7f-\xff]/g;
function l(a,b){b.push('"',a.replace(n,function(a){if(a in m)return m[a];var b=a.charCodeAt(0),d="\\u";16>b?d+="000":256>b?d+="00":4096>b&&(d+="0");return m[a]=d+b.toString(16)}),'"')};window.JSON||(window.JSON={});"function"!==typeof window.JSON.stringify&&(window.JSON.stringify=i);"function"!==typeof window.JSON.parse&&(window.JSON.parse=h);
})();
Maintenant, vous pouvez appeler:
var JSONString = JSON.stringify({name: 'value'});
