Javascript 在空格或引号上将字符串拆分为数组

Question

var str = 'single words "fixed string of words"';
var astr = str.split(" "); // need fix

我希望数组是这样的:

var astr = ["single", "words", "fixed string of words"];

Answer 1

接受的答案并不完全正确。它分隔非空格字符，如 .和 - 并在结果中留下引号。执行此操作以排除引号的更好方法是使用捕获组，例如:

//The parenthesis in the regex creates a captured group within the quotes
var myRegexp = /[^\s"]+|"([^"]*)"/gi;
var myString = 'single words "fixed string of words"';
var myArray = [];

do {
    //Each call to exec returns the next regex match as an array
    var match = myRegexp.exec(myString);
    if (match != null)
    {
        //Index 1 in the array is the captured group if it exists
        //Index 0 is the matched text, which we use if no captured group exists
        myArray.push(match[1] ? match[1] : match[0]);
    }
} while (match != null);

myArray 现在将包含 OP 要求的内容:

single,words,fixed string of words
