Converting circular structure to JSON

管理系统在firefox开发，目前要兼容google chrome 。。firefox 下一切正常运行，但是在google chrome下出现这个错误提示：Converting circular structure to JSON

MiscUtils.clone = function(object) {
return JSON.parse(JSON.stringify(object)); //出现错误提示代码行
};

网络上关于这个错误的说明：

It means that the object you pass in the request (I guess it ispagedoc) has a circular reference, something like:

JSON.stringifycannot convert structures like this.

N.B.: This would be the case with DOM nodes, which have circular references, even if they are not attached to the DOM tree. Each node has anownerDocumentwhich refers todocumentin most cases.documenthas a reference to the DOM tree at least throughdocument.bodyanddocument.body.ownerDocumentrefers back todocumentagain, which is onlyoneof multiple circular references in the DOM tree.

最后的解决方法：

MiscUtils.clone = function(object) {
return object;
};

该方法的功能是克隆一个对象，传过来的参数也是一个object类型，所以就没有必要先转成string ，然后再转成object类型。。
