JSON方法远不如Gecko引擎的. tosource()原语。

有关比较测试，请参阅SO文章响应。

同样，上面的答案指的是http://forums.devshed.com/javascript-development-115/tosource-with-arrays-in-ie-386109.html，它像JSON一样(另一篇文章http://www.davidpirek.com/blog/object-to-string-how-to-deserialize-json通过“ExtJs JSON编码源代码”使用)不能处理循环引用，并且是不完整的。下面的代码显示了它的(欺骗的)限制(修正为处理无内容的数组和对象)。

在你知道对象只是一个布尔值的情况下，日期，字符串，数字等…javascript的String()函数工作得很好。我最近发现这在处理来自jquery的$的值时很有用。每个函数。

例如，下面将“value”中的所有项转换为字符串:

$.each(this, function (name, value) {
  alert(String(value));
});

详情如下:

http://www.w3schools.com/jsref/jsref_string.asp

/*
    This function is as JSON.Stringify (but if you has not in your js-engine you can use this)
    Params:
        obj - your object
        inc_ident - can be " " or "\t".
        show_types - show types of object or not
        ident - need for recoursion but you can not set this parameter.
*/
function getAsText(obj, inc_ident, show_types, ident) {
    var res = "";
    if (!ident)
        ident = "";
    if (typeof(obj) == "string") {
        res += "\"" + obj + "\" ";
        res += (show_types == true) ? "/* typeobj: " + typeof(obj) + "*/" : "";
    } else if (typeof(obj) == "number" || typeof(obj) == "boolean") {
        res += obj;
        res += (show_types == true) ? "/* typeobj: " + typeof(obj) + "*/" : "";
    } else if (obj instanceof Array) {
        res += "[ ";
        res += show_types ? "/* typeobj: " + typeof(obj) + "*/" : "";
        res += "\r\n";
        var new_ident = ident + inc_ident;
        var arr = [];
        for(var key in obj) {
            arr.push(new_ident + getAsText(obj[key], inc_ident, show_types, new_ident));
        } 
        res += arr.join(",\r\n") + "\r\n";
        res += ident + "]";
    } else {
        var new_ident = ident + inc_ident;      
        res += "{ ";
        res += (show_types == true) ? "/* typeobj: " + typeof(obj) + "*/" : "";
        res += "\r\n";
        var arr = [];
        for(var key in obj) {
            arr.push(new_ident + '"' + key + "\" : " + getAsText(obj[key], inc_ident, show_types, new_ident));
        }
        res += arr.join(",\r\n") + "\r\n";
        res += ident + "}\r\n";
    } 
    return res;
};

示例:

var obj = {
    str : "hello",
    arr : ["1", "2", "3", 4],
b : true,
    vobj : {
        str : "hello2"
    }
}

var ForReading = 1, ForWriting = 2;
var fso = new ActiveXObject("Scripting.FileSystemObject")
f1 = fso.OpenTextFile("your_object1.txt", ForWriting, true)
f1.Write(getAsText(obj, "\t"));
f1.Close();

f2 = fso.OpenTextFile("your_object2.txt", ForWriting, true)
f2.Write(getAsText(obj, "\t", true));
f2.Close();

your_object1.txt:

{ 
    "str" : "hello" ,
    "arr" : [ 
        "1" ,
        "2" ,
        "3" ,
        4
    ],
    "b" : true,
    "vobj" : { 
        "str" : "hello2" 
    }

}

your_object2.txt:

{ /* typeobj: object*/
    "str" : "hello" /* typeobj: string*/,
    "arr" : [ /* typeobj: object*/
        "1" /* typeobj: string*/,
        "2" /* typeobj: string*/,
        "3" /* typeobj: string*/,
        4/* typeobj: number*/
    ],
    "b" : true/* typeobj: boolean*/,
    "vobj" : { /* typeobj: object*/
        "str" : "hello2" /* typeobj: string*/
    }

}

我需要制作一个更可配置的JSON版本。stringify，因为我必须添加注释和知道JSON路径:

const someObj = { a: { nested: { value: 'apple', }, sibling: 'peanut' }, b: { languages: ['en', 'de', 'fr'], c: { nice: 'heh' } }, c: 'butter', d: function () {} }; function* objIter(obj, indent = ' ', depth = 0, path = '') { const t = indent.repeat(depth); const t1 = indent.repeat(depth + 1); const v = v => JSON.stringify(v); yield { type: Array.isArray(obj) ? 'OPEN_ARR' : 'OPEN_OBJ', indent, depth }; const keys = Object.keys(obj); for (let i = 0, l = keys.length; i < l; i++) { const key = keys[i]; const prop = obj[key]; const nextPath = !path && key || `${path}.${key}`; if (typeof prop !== 'object') { yield { type: isNaN(key) ? 'VAL' : 'ARR_VAL', key, prop, indent, depth, path: nextPath }; } else { yield { type: 'OBJ_KEY', key, indent, depth, path: nextPath }; yield* objIter(prop, indent, depth + 1, nextPath); } } yield { type: Array.isArray(obj) ? 'CLOSE_ARR' : 'CLOSE_OBJ', indent, depth }; } const iterMap = (it, mapFn) => { const arr = []; for (const x of it) { arr.push(mapFn(x)) } return arr; } const objToStr = obj => iterMap(objIter(obj), ({ type, key, prop, indent, depth, path }) => { const t = indent.repeat(depth); const t1 = indent.repeat(depth + 1); const v = v => JSON.stringify(v); switch (type) { case 'OPEN_ARR': return '[\n'; case 'OPEN_OBJ': return '{\n'; case 'VAL': return `${t1}// ${path}\n${t1}${v(key)}: ${v(prop)},\n`; case 'ARR_VAL': return `${t1}// ${path}\n${t1}${v(prop)},\n`; case 'OBJ_KEY': return `${t1}// ${path}\n${t1}${v(key)}: `; case 'CLOSE_ARR': case 'CLOSE_OBJ': return `${t}${type === 'CLOSE_ARR' ? ']' : '}'}${depth ? ',' : ';'}\n`; default: throw new Error('Unknown type:', type); } }).join(''); const s = objToStr(someObj); console.log(s);

这里没有一个解决方案对我有效。JSON。stringify似乎是很多人所说的，但它削减了函数，并且在我测试时尝试的一些对象和数组似乎很坏。

我做了自己的解决方案，至少在Chrome中工作。把它贴在这里，这样任何在谷歌上看到的人都能找到它。

//Make an object a string that evaluates to an equivalent object
//  Note that eval() seems tricky and sometimes you have to do
//  something like eval("a = " + yourString), then use the value
//  of a.
//
//  Also this leaves extra commas after everything, but JavaScript
//  ignores them.
function convertToText(obj) {
    //create an array that will later be joined into a string.
    var string = [];

    //is object
    //    Both arrays and objects seem to return "object"
    //    when typeof(obj) is applied to them. So instead
    //    I am checking to see if they have the property
    //    join, which normal objects don't have but
    //    arrays do.
    if (typeof(obj) == "object" && (obj.join == undefined)) {
        string.push("{");
        for (prop in obj) {
            string.push(prop, ": ", convertToText(obj[prop]), ",");
        };
        string.push("}");

    //is array
    } else if (typeof(obj) == "object" && !(obj.join == undefined)) {
        string.push("[")
        for(prop in obj) {
            string.push(convertToText(obj[prop]), ",");
        }
        string.push("]")

    //is function
    } else if (typeof(obj) == "function") {
        string.push(obj.toString())

    //all other values can be done with JSON.stringify
    } else {
        string.push(JSON.stringify(obj))
    }

    return string.join("")
}

编辑:我知道这段代码可以改进，但只是从来没有做过。用户andrey在评论中提出了一个改进:

这里有一点变化的代码，它可以处理'null'和'undefined'，也没有添加过多的逗号。

使用它在你自己的风险，因为我没有验证它在所有。请随意提出任何额外的改进意见。
