JavaScript对象中的属性数量是否有限制？ [英] Are there limits to the number of properties in a JavaScript object?

问题描述

我们有一个超过75000个属性的对象。对象的格式如下：

We have an object with more than 75000 properties. The format of the object is as following:

// The key starts with 3 letters and then is followed by 8 numbers
var bigArray = {'AAA########':123456789,
                'AAA########':123456790,
                'AAA########':123456791
               }; 

是否已知JavaScript对象的属性数量限制？从我的测试中，对象仍然可以在65500个元素上运行。

Is there a known limit of the quantity of properties for JavaScript objects? From my tests the object still works at 65500 elements.

• 在Windows 7中，IE9脚本崩溃（错误-2147024882）。


• Windows XP，IE8正常工作。

推荐答案

来自我们在这个问题上进行测试似乎IE9，Windows 7，将HTA脚本中的行数限制为65535.我没有找到任何关于此问题的来源，这只是我们测试的结果。

From our test on this issue it seems that IE9, Windows 7, limits the number of line in a HTA script to 65535. I did not find any source on the issue, it is just the results of our tests.
