Question

在我的Javascript代码中，我有一个类似这样的字符串：

"1943[15]43[67]12[32]"

我想返回一个这样的数组：

["1","9","4","3","15","4","3","67","1", 2","32"]

也就是说，我希望它将每个字符分开，但括号内的数字除外，我想将其保留为一个元素。

有优雅的方法吗？

Answer 1

var str = '1943[15]43[67]12[32]',
    matches = str.match(/\d|\[\d+\]/g);

for (var i = 0, matchesLength = matches.length; i < matchesLength; i++) {
    matches[i] = matches[i].replace(/\D/g, '');
};

console.log(matches);
// ["1", "9", "4", "3", "15", "4", "3", "67", "1", "2", "32"]

Answer 2

var str = "1943[15]43[67]12[32]", 
    re = new RegExp(/(\d)|\[(\d+)\]/g), 
    out = [],
    m;

while (m = re.exec(str)) { 
  out.push(m[2] || m[0]); 
}

console.log(out); // ["1", "9", "4", "3", "15", "4", "3", "67", "1", "2", "32"]

在Javascript中使用内部和外部分隔符拆分字符串
