对象文字可以嵌套多远? [英] How far can an object literal be nested?

问题描述

我发现可以将另一个属性嵌套在对象文字属性内.这是一个示例:

I have found that it is possible to nest another property within an object literal property. Here is an example of this:

var rectangle = { 
    upperLeft : { x : 2, y : 2 },
    lowerRight : { x : 4, y : 4}
};

但是，当我尝试在该嵌套属性中嵌套另一个属性时，我无法使其正常工作.也许我的语法不正确?这是我的代码:

However, when I tried to nest yet another property within that nested property, I could not get this to work. Is maybe my syntax incorrect? Here is my code:

var rectangle = { 
    upperLeft : { x : {min: 2, max: 4}, y : 2 },
    lowerRight : { x : {min: 4, max: 6}, y : 4}
};

推荐答案

您的第二个示例很好.当您访问时:

Your second sample is fine. When you access:

rectangle.upperLeft.x.min

它正确返回2.您遇到什么问题?请注意，没有理论上的最大嵌套级别.

it correctly returns 2. What problems do you encounter? Note that there is no theoretical maximum nesting level.
