如何在javascript中一定数量的字符后的空格处分割字符串?

问题描述

所以我有一个不错的长字符串，我需要在Javascript中的一定数量字符后的空格处分割它.例如，如果我有

So I have a nice long string that I need to split in Javascript at a space following a certain amount of characters. For instance, if I have

你是狗，我是猫."

我希望它在10个字符之后但在下一个空格处拆分...因此，我不想将狗拆分掉，而是希望下一个空格作为拆分点.

and I want it to split after 10 characters but at the next space... so rather than splitting dog up I want the next space to be the split point.

我希望我写得清楚些，解释起来有点尴尬.

I hope I wrote that clearly, its a bit awkward to explain.

我需要将所有这些存储到一个数组中.因此，按照我的描述将字符串拆分开，但是将其存储到一个数组中，可以进行迭代.抱歉让我感到困惑，就像我说的那样，有点奇怪.

I need to store all of this into an array. So splitting the string up as I described, but storing it into an array which I can iterate through. Sorry for the confusion- like I said, a bit odd to describe.

推荐答案

考虑:

str = "How razorback-jumping frogs can level six piqued gymnasts!"
result = str.replace(/.{10}\S*\s+/g, "$&@").split(/\s+@/)

结果:

[
 "How razorback-jumping",
 "frogs can level",
 "six piqued",
 "gymnasts!"
]
