循环结构(Cyclic Structures)是指在对象的属性之间存在相互引用的情况。例如,对象A的属性指向对象B,而对象B的属性又反过来指向对象A,形成了一个闭环。这种相互引用导致了对象的图结构中存在环,因此被称为循环结构。 2. 为什么JSON.stringify不能序列化循环结构? JSON.stringify方法用于将JavaScript对象转换为JSON字符串。
JSON.stringify报cyclic object value错误 这是一个典型的循环引用的错误,一个对象里引用自己就会立刻得到这个错误: 1 2 3 4 5 6 7 8 9 obj = { x:555, y:"hi"}; obj.myself = obj; try{ json = JSON.stringify(obj); alert(json) }catch(e){ alert(e); } 演示:http://jsfiddle.net/walk...

The cyclic reference between error.config and config.cancelToken (where cancelToken.reason points back to config) caused JSON.stringify to overflow. This commit clones the config and cancelToken objects and deletes the 'reason' property to break the cycle while preserving that cancelToken was provided...

JSON.stringify() needs to get key-array first, and then get the value. It will trigger the call of Reflect.ownKeys(). The return of ownKeys will not be directly used as the key-array, Enumerable of the attribute will be verified here. But this verification does not seem to be performed...
JSON.parse & JSON.stringify have limitation by design, because there are no data formats for things like Date Function Class Symbol Error etc. Also JSON doesn't support cyclic data structures. This library allows you to pass in data with all of the above properties. It will transform the pr...
