问题描述
默认情况下,每个JavaScript数组的索引都从0开始.我想创建一个索引从1开始的数组.
By default the indexing of every JavaScript array starts from 0. I want to create an array whose indexing starts from 1 instead.
我知道,一定很琐碎...谢谢您的帮助.
I know, must be very trivial... Thanks for your help.
推荐答案
这不是小事.不可能.最好的办法是使用从1开始的数值属性创建一个对象,但这不是一回事.
It isn't trivial. It's impossible. The best you could do is create an object using numeric properties starting at 1 but that's not the same thing.
为什么要让它精确地从1开始?要么
Why exactly do you want it to start at 1? Either:
-
从0开始,并根据需要调整索引;或
Start at 0 and adjust your indices as necessary; or
从0开始,只是忽略索引0(即仅使用索引1和更高).
Start at 0 and just ignore index 0 (ie only use indices 1 and up).
