下面是在ES6中实现相同的新方法:

SplitByString(source, splitBy) { var splitter = splitBy.split("); splitter.push([源]);//推送初始值 返回分配器。reduceRight(函数(累加器，curValue) { Var k = []; 蓄电池。v => k =[…k…v.split (curValue)]); 返回k; })； ｝ Var source = "abc,def#hijk*lmn,opq#rst*uvw,xyz"; var splitBy = "，*#"; splitBy console.log (SplitByString(源));

在这个函数中请注意:

不涉及正则表达式 以源代码中显示的相同顺序返回拆分后的值

以上代码的结果为:

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"]

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);
}

你可以看到代码在playground中运行: https://codeguppy.com/code.html?IJI0E4OGnkyTZnoszAzf

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.
