JSON.stringify（）的第二个参数还允许您指定一个关键字名称数组，该数组应保存在数据中遇到的每个对象中。这可能不适用于所有用例，但却是一个简单得多的解决方案。

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify

var obj = {
    a: "foo",
    b: this
}

var json = JSON.stringify(obj, ['a']);
console.log(json);
// {"a":"foo"}

注意：奇怪的是，OP中的对象定义在最新的Chrome或Firefox中没有抛出循环引用错误。这个答案中的定义被修改了，所以它确实抛出了一个错误。

superserial完全序列化JavaScript对象。

https://github.com/denostack/superserial

用法：

const serializer = new Serializer();

const nodes = [{ self: null as any, siblings: [] as any[] }, {
  self: null as any,
  siblings: [] as any[],
}];
nodes[0].self = nodes[0];
nodes[0].siblings = nodes;
nodes[1].self = nodes[1];
nodes[1].siblings = nodes;

const serialized = serializer.serialize(nodes);

console.log(serialized);

输出：

[$1,$2];{"self":$1,"siblings":$0};{"self":$2,"siblings":$0}

我们使用对象扫描进行数据处理，这可能是一个可行的解决方案。这就是它的工作方式（也可以正确修剪数组）

.作为控制台包装｛最大高度：100%！重要；顶部：0｝<script type=“module”>导入对象扫描自'https://cdn.jsdelivr.net/npm/object-scan@18.1.2/lib/index.min.js'；const prune=（data）=>对象扫描（['**']{rtn：'计数'，filterFn：（｛isCircular，父级，属性｝）=>{if（isCircular）{if（Array.isArray（父级））{parent.splice（属性，1）；}其他{删除父项[属性]；}返回true；}return false；},breakFn:（｛isCircular｝）=>isCircular==true})（数据）；常量obj={a:'foo'，c:[0]}；obj.b=对象；obj.c.push（obj）；console.log（obj）；//=><ref*1>｛a:'foo'，c:[0，[Circular*1]]，b:[Circulal*1]｝console.log（prune（obj））；//返回循环计数// => 2console.log（obj）；//=>｛a:'foo'，c:[0]｝</script>

免责声明：我是物体扫描的作者

使用带有替换符的JSON.stringify方法。有关详细信息，请阅读本文档。http://msdn.microsoft.com/en-us/library/cc836459%28v=vs.94%29.aspx

var obj = {
  a: "foo",
  b: obj
}

var replacement = {"b":undefined};

alert(JSON.stringify(obj,replacement));

找出用循环引用填充替换数组的方法。您可以使用typeof方法来查找属性的类型是否为“object”（引用），并使用精确的等式检查（==）来验证循环引用。

根据其他答案，我最终得到以下代码。它可以很好地处理循环引用、带有自定义构造函数的对象。

从要序列化的给定对象，

缓存遍历对象时遇到的所有对象，并为每个对象分配一个唯一的hashID（自动递增的数字也有效）找到循环引用后，将新对象中的字段标记为循环，并将原始对象的hashID存储为属性。

console.log(obj); // ORIGINAL

// SERIALIZE AND THEN PARSE
var jsonObj = DJS.stringify(obj);
console.log(DJS.parse(jsonObj));

示例用法2：

// PERSON OBJECT

function Person() {

    this.child = null;
    this.dad = null;
    this.mom = null;
}
var Dad = new Person();

var Child = new Person();
Child.name = 'Kiddo';

Dad.child = Mom.child = Child;
Child.dad = Dad;
Child.mom = Mom;

console.log(Child); // ORIGINAL

// SERIALIZE AND THEN PARSE
var jsonChild = DJS.stringify(Child);
console.log(DJS.parse(jsonChild));

当你不知道所有循环引用的键时，对于未来搜索这个问题解决方案的谷歌用户，你可以使用JSON.stringify函数的包装器来排除循环引用。参见示例脚本https://gist.github.com/4653128.

解决方案本质上归结为在数组中保留对先前打印对象的引用，并在返回值之前在替换函数中检查该引用。它比仅排除循环引用更具限制性，因为它还排除了两次打印对象的可能性，其副作用之一是避免循环引用。

包装示例：

function stringifyOnce(obj, replacer, indent){
    var printedObjects = [];
    var printedObjectKeys = [];

    function printOnceReplacer(key, value){
        var printedObjIndex = false;
        printedObjects.forEach(function(obj, index){
            if(obj===value){
                printedObjIndex = index;
            }
        });

        if(printedObjIndex && typeof(value)=="object"){
            return "(see " + value.constructor.name.toLowerCase() + " with key " + printedObjectKeys[printedObjIndex] + ")";
        }else{
            var qualifiedKey = key || "(empty key)";
            printedObjects.push(value);
            printedObjectKeys.push(qualifiedKey);
            if(replacer){
                return replacer(key, value);
            }else{
                return value;
            }
        }
    }
    return JSON.stringify(obj, printOnceReplacer, indent);
}
