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。


当前回答

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。

从@stephen-sweriduk解决方案开始(这对我来说更有趣!),我对它进行了轻微的修改,使其更加通用和可重用:

/**
 * Adapted from: http://stackoverflow.com/questions/650022/how-do-i-split-a-string-with-multiple-separators-in-javascript
*/
var StringUtils = {

  /**
   * Flatten a list of strings
   * http://rosettacode.org/wiki/Flatten_a_list
   */
  flatten : function(arr) {
    var self=this;
    return arr.reduce(function(acc, val) {
        return acc.concat(val.constructor === Array ? self.flatten(val) : val);
    },[]);
  },

  /**
   * Recursively Traverse a list and apply a function to each item
   * @param list array
   * @param expression Expression to use in func
   * @param func function of (item,expression) to apply expression to item
   *
   */
  traverseListFunc : function(list, expression, index, func) {
    var self=this;
    if(list[index]) {
        if((list.constructor !== String) && (list[index].constructor === String))
            (list[index] != func(list[index], expression)) ? list[index] = func(list[index], expression) : null;
        (list[index].constructor === Array) ? self.traverseListFunc(list[index], expression, 0, func) : null;
        (list.constructor === Array) ? self.traverseListFunc(list, expression, index+1, func) : null;
    }
  },

  /**
   * Recursively map function to string
   * @param string
   * @param expression Expression to apply to func
   * @param function of (item, expressions[i])
   */
  mapFuncToString : function(string, expressions, func) {
    var self=this;
    var list = [string];
    for(var i=0, len=expressions.length; i<len; i++) {
        self.traverseListFunc(list, expressions[i], 0, func);
    }
    return self.flatten(list);
  },

  /**
   * Split a string
   * @param splitters Array of characters to apply the split
   */
  splitString : function(string, splitters) {
    return this.mapFuncToString(string, splitters, function(item, expression) {
      return item.split(expression);
    })
  },

}

然后

var stringToSplit = "people and_other/things";
var splitList = [" ", "_", "/"];
var splittedString=StringUtils.splitString(stringToSplit, splitList);
console.log(splitList, stringToSplit, splittedString);

归还原物的:

[ ' ', '_', '/' ] 'people and_other/things' [ 'people', 'and', 'other', 'things' ]

下面是使用Regex可能会有帮助的一些情况:

\W匹配其他任何字符[a-zA-Z0-9_]。例子:

("Hello World,I-am code").split(/\W+/); // would return [ 'Hello', 'World', 'I', 'am', 'code' ]

一个或多个空格 \d来匹配数字 如果你想用一些字符来分割,你可以使用str.split(/[,-]+/)

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');

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))
