object1作为object2的属性，而object2又是object1的属性 - 会导致内存泄漏吗？ [英] object1 as a property of object2 which is in turn a property of object1 - will result in memory leak?

问题描述

form和form.errorProcessor只是保持对彼此的单个引用，并且在内存中只有2个对象，或者这是泄漏/问题情况？

Will "form" and "form.errorProcessor" just hold single references to each other and have only 2 objects in memory, or is this a leak / problem situation?

var ErrorProcessor = function(form){
    this.form = form; // Problem Line
}
var form = $("form");
form.errorProcessor = new ErrorProcessor(form); // Some element assignment

发布问题行后，我有一个对象层次结构，如下所示[由控制台检查] .log（form）]

Post the problem line, I have an object hierarchy as below [checked by console.log(form)]

form：{errorProcessor：{form：{errorProcessor：{form：{errorProcessor：{...}}}}}}

form: {errorProcessor: {form: {errorProcessor: {form: {errorProcessor: {...}}}}}}

推荐答案

不，循环引用没有内存泄漏，并且您在代码中只创建了两个对象。任何体面的垃圾收集器都可以处理它们。

No, there is no memory leak caused by circular references, and you are creating only two objects in your code. Any decent garbage collector can handle them.

唯一的问题是当您递归检查对象时（就像在控制台中扩展其属性一样），无底洞 - 如果以编程方式完成，您将从递归中获得无限循环或堆栈溢出。但是，您在控制台中看到的所有这些结构都代表同一个对象。

The only problem is when you recursively inspect your object (like you do with expanding its properties in the console), you go down a bottomless pit - if done programmatically, you'd get an infinite loop or stack overflow from recursion. All these structures you see in your console are representing the same object, though.
