for（var i in obj）问题 [英] for (var i in obj) question

问题描述

我有一个对象数组。


我在表格中显示数组的内容。


然后我有一个链接它允许用户对表进行排序。我这样做是通过排序数组，删除表的内容，然后重新显示数组的内容。但是for（var i in obj）似乎使用原始订单。我可以在firebug中看到数组已正确排序。那么为什么它保持原始的排序顺序呢？


这是我的示例代码，下面是排序后数组的屏幕截图;

I have an array of objects.

I display the content of the array in a table.

Then I have a link which lets the user sort the table. I do that by sorting the array, delete the content of the table and then redisplay the content of the array. But the "for (var i in obj)" seems to use the original order. I can see in firebug that the array is properly sorted. So why does it maintain the original sort order?

Here is my sample code and below is a screen shot of the array after sorting;

推荐答案

在尝试自己时，排序发生。

upon trying myself, sorting occured.

我刚刚添加了一张图片从萤火虫看到的阵列。对数组进行排序，但是for（var i in obj）正在使用原始排序顺序。为什么会这样？

I just added a picture of the array as viewed from firebug. The array is sorted but the "for ( var i in obj)" is using the original sort order. Why would this be?

从图片判断， a7DayKeys 不是标准数组（除了Firebug总是显示属性和方法排序）


出于兴趣，

judging from the picture, a7DayKeys is not a standard array (besides that Firebug always display the properties and methods sorted)
