我如何分裂一个字符串与多个分隔符在JavaScript?

我试图拆分逗号和空格,但AFAIK JavaScript的split()函数只支持一个分隔符。

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"]

棘手的方法:

var s = "dasdnk asd, (naks) :d skldma";
var a = s.replace('(',' ').replace(')',' ').replace(',',' ').split(' ');
console.log(a);//["dasdnk", "asd", "naks", ":d", "skldma"]

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))

我很惊讶没有人建议它,但我的hack-ey(疯狂的快速)解决方案是附加几个“替换”调用之前由相同的字符分裂。

即删除a, b, c, d和e:

let str = 'afgbfgcfgdfgefg'
let array = str.replace('a','d').replace('b','d').replace('c','d').replace('e','d').split('d')

这可以方便地概括为一个拆分器数组,如下:

function splitByMany( manyArgs, string ) {
  do {
    let arg = manyArgs.pop()
    string = string.replace(arg, manyArgs[0])
  } while (manyArgs.length > 2)
  return string.split(manyArgs[0])
}

因此,在您的情况下,您可以调用

let array = splitByMany([" ", ","], 'My long string containing commas, and spaces, and more commas');
a = "a=b,c:d"

array = ['=',',',':'];

for(i=0; i< array.length; i++){ a= a.split(array[i]).join(); }

这将返回没有特殊字符的字符串。

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>
