Javascript正則分組命名

Javascript的正則分組不支援命名，只好自己搞了一個。先把命名存入數組，然後匹配。

唉~~~有更好的解決方案嗎？

代碼：

var route = '/{controller}/{action}/{id}',    url = '/home/index/2';groupRE(route, url); // ==> {controller:'home', action:'index', id:'2'}/** @re: string, e.g.: '/{controller}/{action}/{id}'* @s: string to match, e.g.: 'home/index/2'* @return: dict, e.g.: {controller:'home', action:'index', id:'2'}*/function groupRE(re, s){    var names = [], result = {}, cursor = 0;    re = re.replace(/\{([^}]+)\}/g, function(m, g1){        names.push(g1);        return '(.+)';    });    re = new RegExp(re);    var tmp = re.exec(s);if(tmp){for(var i=1; i<tmp.length; i++){if(names[i-1]){result[ names[i-1] ] = tmp[i];}}}    return result;}
