如果你真的不想访问或与repo交互，下面是工作代码:

/**
 * 
 * @param {type} input The string input to be split
 * @param {type} includeTokensInOutput If true, the tokens are retained in the splitted output.
 * @param {type} tokens The tokens to be employed in splitting the original string.
 * @returns {Scanner}
 */
function Scanner(input, includeTokensInOutput, tokens) {
    this.input = input;
    this.includeTokensInOutput = includeTokensInOutput;
    this.tokens = tokens;
}

Scanner.prototype.scan = function () {
    var inp = this.input;

    var parse = [];
    this.tokens.sort(function (a, b) {
        return b.length - a.length; //ASC, For Descending order use: b - a
    });
    for (var i = 0; i < inp.length; i++) {


        for (var j = 0; j < this.tokens.length; j++) {

            var token = this.tokens[j];
            var len = token.length;
            if (len > 0 && i + len <= inp.length) {
                var portion = inp.substring(i, i + len);
                if (portion === token) {
                    if (i !== 0) {//avoid empty spaces
                        parse[parse.length] = inp.substring(0, i);
                    }
                    if (this.includeTokensInOutput) {
                        parse[parse.length] = token;
                    }
                    inp = inp.substring(i + len);
                    i = -1;
                    break;
                }

            }

        }

    }
    if (inp.length > 0) {
          parse[parse.length] = inp;
    }

    return parse;


};

用法很简单:

    var tokens = new Scanner("ABC+DE-GHIJK+LMNOP", false , new Array('+','-')).scan();

console.log(tokens); 

给:

['ABC', 'DE', 'GHIJK', 'LMNOP']

如果您希望在输出中包含分隔令牌(+和-)，将false设置为true，瞧!它仍然有效。

现在的用法是:

var tokens = new Scanner("ABC+DE-GHIJK+LMNOP", true , new Array('+','-')).scan();

and

console.log(tokens);

将:

['ABC', '+', 'DE', '-', 'GHIJK', '+', 'LMNOP']

享受吧!

我使用regexp:

str =  'Write a program that extracts from a given text all palindromes, e.g. "ABBA", "lamal", "exe".';

var strNew = str.match(/\w+/g);

// Output: ["Write", "a", "program", "that", "extracts", "from", "a", "given", "text", "all", "palindromes", "e", "g", "ABBA", "lamal", "exe"]

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!"

我在寻找c# string. split()函数的替代品时遇到了这个问题，该函数使用参数中的字符分割字符串。

在JavaScript中，你可以使用map和reduce来迭代分隔字符和中间值:

let splitters = [",", ":", ";"]; // or ",:;".split("");
let start= "a,b;c:d";
let values = splitters.reduce((old, c) => old.map(v => v.split(c)).flat(), [start]);
// values is ["a", "b", "c", "d"]

Flat()用于平滑中间结果，因此每次迭代都处理没有嵌套数组的字符串列表。每次迭代对old中的所有值应用split，然后返回拆分器中要被下一个值拆分的中间结果列表。Reduce()使用包含初始字符串值的数组进行初始化。

我用缩减和过滤解决了这个问题。它可能不是最易读的解决方案，也不是最快的，在现实生活中，我可能会在这里使用aaron的答案，但写起来很有趣。

[' ','_','-','.',',',':','@'].reduce(
(segs, sep) => segs.reduce(
(out, seg) => out.concat(seg.split(sep)), []), 
['E-mail Address: user@domain.com, Phone Number: +1-800-555-0011']
).filter(x => x)

或作为一个函数:

function msplit(str, seps) {
  return seps.reduce((segs, sep) => segs.reduce(
    (out, seg) => out.concat(seg.split(sep)), []
  ), [str]).filter(x => x);
}

这将输出:

['E','mail','Address','user','domain','com','0','Phone','Number','+1','800','555','0011']

如果没有最后的过滤器，你将在数组中得到空字符串，其中两个不同的分隔符彼此相邻。

不是最好的方法，但适用于使用多个和不同的分隔符/分隔符进行分割

html

<button onclick="myFunction()">Split with Multiple and Different seperators/delimiters</button>
<p id="demo"></p>

javascript

<script>
function myFunction() {

 var str = "How : are | you doing : today?";
 var res = str.split(' | ');

 var str2 = '';
 var i;
 for (i = 0; i < res.length; i++) { 
    str2 += res[i];
    
    if (i != res.length-1) {
      str2 += ",";
    }
 }
 var res2 = str2.split(' : ');

 //you can add countless options (with or without space)

 document.getElementById("demo").innerHTML = res2;
}
</script>
