使用javascript正则表达式提取字符串

Question

Given:
"4 John Smith Rd., Pasadena 94786" or
"4 John Smith Rd., North Pasadena 94786".

The following regex failed to extract the City in array index 0 and the zip code in array index.

How to fix it? thx

doc.address.match(/, (\\w+) +(\\d{5})/g);

Answer 1

 var address = ["4 John Smith Rd., Pasadena 94786", "4 John Smith Rd., North Pasadena 94786" ] for(var i in address){ console.log(address[i].match(/, (.+)? +(\\d{5})/)); } 

group1 is city and group2 is the zip code.

Answer 2

If match is successful, the captures will begin at the first index. Try:

var result = docs.address.match(/, ([\w ]+) (\d{5})/i);
var city = result[1];
var zip = result[2];

But this is pretty naïve address parsing. There are libraries dedicated to this.

Answer 3

This will match all after the .,

var rs = docs.address.match(/[^\.\,](\w+ ){1,}(\d+)/);

Dont match the . and , then match any word after it, then match the ZIP code
