node.js正则表达式拆分字符串以发送到另一台服务器

Question

I'm trying to split this type of string in node.js currently to send information from one server to another. I'm having trouble getting any regular expression to work considering I kind of stink at Regular Expressions in Node.js or any language at the moment. I'm trying to make it easier on myself without having a bunch of strings that replace or are split into an array. So, here's the string:

?name!identity@url.url

Is it possible to just get the name from this string without .replace() and .split()?

Answer 1

using matching groups:

 var myString = "?name!identity@url.url"; var myRegexp = /\\?(.*?)\\!.+?/g; var match = myRegexp.exec(myString); if(match) { alert(match[1]); // name } else { alert("no match"); }
