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

我们有一个拥有超过 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
               }; 

JavaScript 对象的属性数量是否有已知限制?根据我的测试，该对象在 65500 个元素上仍然有效.

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、IE9 中，脚本崩溃(错误 -2147024882).
• Windows XP、IE8 运行良好.

推荐答案

从我们对这个问题的测试来看，IE9、Windows 7 似乎将 HTA 脚本中的行数限制为 65535.我没有找到任何来源问题，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.
