Javascript searcing and replacing?

I want to change a string which start 'a' and end 'n'.

For example: "action" I want to replace 'ctio' and all starting 'a' and finishing 'n' with ''.

How can do it?

var sub = "hello";
str.replace(/(<)(\w+)(")/igm,"$1" + sub + "$3");

in Javascript:

var substitute = "\"";
var text = "action";
var text = text.replace(/\b(a)([a-z]+?)(n)\b/gim,"$1" + substitute + "$3");
// result = a"n ... if what  you really want is a double quote here

I'm not really sure what you're trying to do, but I'm guessing going from "action" to "ctio"?

var foo = 'action';
if (foo.substr(0,1)=='a' && foo.substr(-1,1)=='n') {
  var bar = foo.substr(1,foo.length-2);
  alert(bar); // ctio
}
