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"]

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"]

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))

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"]

我认为如果你指定你想要保留什么，而不是你想要删除什么，会更容易。

如果你只想要英语单词，你可以这样用:

text.match(/[a-z'\-]+/gi);

示例(运行片段):

var R=[/[a-z'\-]+/gi,/[a-z'\-\s]+/gi]; var s=document.getElementById('s'); for(var i=0;i<R.length;i++) { var o=document.createElement('option'); o.innerText=R[i]+''; o.value=i; s.appendChild(o); } var t=document.getElementById('t'); var r=document.getElementById('r'); s.onchange=function() { r.innerHTML=''; var x=s.value; if((x>=0)&&(x<R.length)) x=t.value.match(R[x]); for(i=0;i<x.length;i++) { var li=document.createElement('li'); li.innerText=x[i]; r.appendChild(li); } } <textarea id="t" style="width:70%;height:12em">even, test; spider-man But saying o'er what I have said before: My child is yet a stranger in the world; She hath not seen the change of fourteen years, Let two more summers wither in their pride, Ere we may think her ripe to be a bride. —Shakespeare, William.
