Chrome在展开时显示不同的对象内容 [英] Chrome displays different object contents on expand

问题描述

为什么Chrome会显示两个不同的数据集，具体取决于您是否扩展了对象视图？

Why does Chrome display two differing datasets depending on if you have the object view expanded?

在缩小视图中，我的对象有两个属性：

In contracted view, my object has two properties:

在扩展视图中，我的对象有三个属性：

In expanded view, my object has three properties:

推荐答案

您在控制台中看到的对象是特定时间点的对象快照 - 您登录时的时间。当您展开对象时，它将再次评估属性。

The object you see in the console is a snapshot of the object at a particular point in time - the time when you logged it. When you expand the object, it will evaluate the properties again.

在下面的示例中，我创建了一个具有两个数组属性的对象。我将它记录在控制台上，然后向它添加了第三个属性 c 。

In the example below, I have created an object with two array properties. I logged it the console, and then I added a third property, c to it.

只有前两个属性仍然显示，即使我刚刚添加了第三个属性。在控制台中展开对象后，我可以看到第三个。这是该对象的最新状态。

Only the first two properties are showing still, even though I just added a third property. After expanding the object in the console, I can see the third one. It is the latest state of the object.

如果你将鼠标悬停在小蓝色 i 图标上，即可解释所做的操作：
