传入一个regexp作为参数:

js> "Hello awesome, world!".split(/[\s,]+/)
Hello,awesome,world!

编辑补充:

你可以通过选择数组的长度减去1来获得最后一个元素:

>>> bits = "Hello awesome, world!".split(/[\s,]+/)
["Hello", "awesome", "world!"]
>>> bit = bits[bits.length - 1]
"world!"

．.． 如果模式不匹配:

>>> bits = "Hello awesome, world!".split(/foo/)
["Hello awesome, world!"]
>>> bits[bits.length - 1]
"Hello awesome, world!"

我发现我需要这样做的主要原因之一是在/和\上拆分文件路径。这是一个有点棘手的正则表达式，所以我将它贴在这里作为参考:

var splitFilePath = filePath.split(/[\/\\]/);

我将为这样的函数提供一个经典的实现。代码可以在几乎所有版本的JavaScript中运行，并且在某种程度上是最优的。

它不使用正则表达式，这很难维护 它没有使用JavaScript的新特性 它不使用需要更多计算机内存的多次.split() .join()调用

只是纯代码:

var text = "Create a function, that will return an array (of string), with the words inside the text";

println(getWords(text));

function getWords(text)
{
    let startWord = -1;
    let ar = [];

    for(let i = 0; i <= text.length; i++)
    {
        let c = i < text.length ? text[i] : " ";

        if (!isSeparator(c) && startWord < 0)
        {
            startWord = i;
        }

        if (isSeparator(c) && startWord >= 0)
        {
            let word = text.substring(startWord, i);
            ar.push(word);

            startWord = -1;
        }
    }

    return ar;
}

function isSeparator(c)
{
    var separators = [" ", "\t", "\n", "\r", ",", ";", ".", "!", "?", "(", ")"];
    return separators.includes(c);
}

让我们保持简单:(在你的RegEx中添加“[]+”表示“1或更多”)

这意味着“+”和“{1，}”是相同的。

var words = text.split(/[ .:;?!~,`"&|()<>{}\[\]\r\n/\\]+/); // note ' and - are kept

My refactor of @Brian answer var string = 'and this is some kind of information and another text and simple and some egample or red or text'; var separators = ['and', 'or']; function splitMulti(str, separators){ var tempChar = 't3mp'; //prevent short text separator in split down //split by regex e.g. \b(or|and)\b var re = new RegExp('\\b(' + separators.join('|') + ')\\b' , "g"); str = str.replace(re, tempChar).split(tempChar); // trim & remove empty return str.map(el => el.trim()).filter(el => el.length > 0); } console.log(splitMulti(string, separators))
