分割字符串在JavaScript中

Question

內外定界符在我的JavaScript代碼，我有一個字符串，它是這樣的：

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

我想返回一個這樣的數組：

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

也就是說，我希望它將每個字符都分開，除了括號內的數字，我想將它們保留爲一個元素。

有沒有一個優雅的方式來做到這一點？

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"] 

jsFiddle。

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"]
