regex - Help parsing string (City, State Zip) with JavaScript -

i've got string following format:

city, state zip

i'd city , state string.

how can javascript? edit: note doesn't mention has zip code when gets here, if helps in solution ~~ drachenstern

var address = "san francisco, ca 94129";  function parseaddress(address) {     // make sure address string.     if (typeof address !== "string") throw "address not string.";      // trim address.     address = address.trim();      // make object contain data.     var returned = {};      // find comma.     var comma = address.indexof(',');      // pull out city.     returned.city = address.slice(0, comma);      // after city.     var after = address.substring(comma + 2); // string after comma, +2 skip comma , space.      // find space.     var space = after.lastindexof(' ');      // pull out state.     returned.state = after.slice(0, space);      // pull out zip code.     returned.zip = after.substring(space + 1);      // return data.     return returned; }  address = parseaddress(address); 

this better using regular expressions , string.split(), takes account state , city may have spaces.

edit: bug fix: included first word of multi-word state names.

and here's minified version. :d

function parseaddress(a) {if(typeof a!=="string") throw "address not string.";a=a.trim();var r={},c=a.indexof(',');r.city=a.slice(0,c);var f=a.substring(c+2),s=f.lastindexof(' ');r.state=f.slice(0,s);r.zip=f.substring(s+1);return r;}
