setInterval的最大延迟是多少？ [英] What is the maximum delay for setInterval?

问题描述

我在Firefox 15和Chrome 21上遇到以下代码问题：

I'm having problems on Firefox 15 and Chrome 21 with the following code:

setInterval(function () { console.log('test') }, 300000000000)

在这两种浏览器上，该功能立即运行很快就重复了。当然，这是一个很大的数字（代表从现在开始大约10年），但我不认为它被视为微小或负数。我没有看到任何文档中允许的最大延迟。有没有人知道是否有标准最大值，或者这只是浏览器有趣吗？

On both browsers, the function is run right away repeats very quickly. Sure, that's a big number (representing about 10 years from now), but I wouldn't expect it to be treated as a tiny or negative number. I haven't seen a maximum allowed delay in any documentation. Does anyone know if there's a standard max, or if this is just the browsers being funny?

推荐答案

我找不到任何目前的文档，但如果定时器值必须符合32位有符号整数，我不会感到惊讶。

I can't find any documentation at the moment, but I wouldn't be surprised if the timer value had to fit in a 32-bit signed integer.
