我有点像这样的弦

aa11b2s
abc1sff3
a1b1sdd2

etc.... i need to change these strings to these

aa 11 b 2 s
abc 1 sff 3
a 1 b 1 sdd 2

简单说说.我需要在每一个(数字/脑)区块之间增加一个空间

最佳回答
var str =  aa11b2s ;
console.log(str.replace(/([d.]+)/g,   $1  ).replace(/^ +| +$/g,   ));
问题回答
var str =  aa11b2s .replace(/([a-z]+|d+)(?!$)/gi,  $1  );
result = subject.replace(/[a-z](?=[0-9])|[0-9](?=[a-z])/ig, "$& ");

此字符匹配一个字母, 之后是一位数字, 或者一个数字, 之后是一位字母, 没有第二个字符 耗尽 < /em> 。 然后用一个字符替换第一个字符, 然后用一个空格取代第一个字符 。
