用逗号分割一个字符串，但使用 Javascript 忽略双引号内的逗号 [英] Split a string by commas but ignore commas within double-quotes using Javascript

问题描述

我正在寻找 [a, b, c, "d, e, f", g, h] 变成 6 个元素的数组:a, b, c, "d,e,f", g, h.我正在尝试通过 Javascript 来做到这一点.这是我目前所拥有的:

I'm looking for [a, b, c, "d, e, f", g, h]to turn into an array of 6 elements: a, b, c, "d,e,f", g, h. I'm trying to do this through Javascript. This is what I have so far:

str = str.split(/,+|"[^"]+"/g); 

但现在它正在拆分双引号中的所有内容，这是不正确的.

But right now it's splitting out everything that's in the double-quotes, which is incorrect.

好的，对不起，我对这个问题的措辞非常糟糕.我得到的是一个字符串而不是一个数组.

Okay sorry I worded this question really poorly. I'm being given a string not an array.

var str = 'a, b, c, "d, e, f", g, h';

我想使用类似split"函数的东西将那个变成一个数组.

And I want to turn that into an array using something like the "split" function.

推荐答案

这就是我要做的.

var str = 'a, b, c, "d, e, f", g, h';
var arr = str.match(/(".*?"|[^",s]+)(?=s*,|s*$)/g);

/* 将匹配:

    (
        ".*?"       double quotes + anything but double quotes + double quotes
        |           OR
        [^",s]+    1 or more characters excl. double quotes, comma or spaces of any kind
    )
    (?=             FOLLOWED BY
        s*,        0 or more empty spaces and a comma
        |           OR
        s*$        0 or more empty spaces and nothing else (end of string)
    )
    
*/
arr = arr || [];
// this will prevent JS from throwing an error in
// the below loop when there are no matches
for (var i = 0; i < arr.length; i++) console.log('arr['+i+'] =',arr[i]);
