正则表达式匹配模式或匹配所有其他内容-匹配优先级问题？

Question

I'm trying to write a regex that will use something like this

/([;\.])|([\s\S]+)/gi

to split this

a.b.cad0i2!--as.d;e;f;g00))(

into this

['a','.','b','.','cad0i2!--as','.','d',';','e',';','f',';','g00))(']

ie. Everything in the original string is in the final array, with the input regex simply listing a complex set of potential delimiters and I don't want to repeat the list of delimiters in the regex.

Is this possible?

Answer 1

Use string.match function.

> "a.b.cad0i2!--as.d;e;f;g00))(".match(/[^;.]+|[;.]/g)
[ 'a',
  '.',
  'b',
  '.',
  'cad0i2!--as',
  '.',
  'd',
  ';',
  'e',
  ';',
  'f',
  ';',
  'g00))(' ]

[^;.]+ matches any character but not of ; or . one or more times.

| OR,

[;.] match ; or .

Answer 2

Try this code:

 var re = /(?=([.;])(?=[^.;]+))/gi; var str = 'abcad0i2!--as.d;e;f;g00))('; var res = []; var result = str.split(re); for (var letter of result) { res.push(letter.replace(/^[.;](?=.+)/, '')); } alert(res); 

Result:

a,.,b,.,cad0i2!--as,.,d,;,e,;,f,;,g00))(
