I am using Coldfusion to do some database work. I have a st­ring of
data that is in the format of "name" <email>


I need to have the information between the <> assigned to a ­variable,

but the length of the field won't be the same each time.
How can I get this done using JavaScript?

Use a regular expression:

var myString = "\"foo<bar\" <abc@def>";
....
var aSubstrs = myString.match(/"[^"]+"\s+<([^>]+)>/),
myMatch = aSubstrs && aSubstrs[1];

Thanks for the info! I do have a couple of questions:

1) var myString = "\"foo<bar\" <abc@def>";

do I just need this in the code once?

2) I noticed the ...... , is there more that goes between the code
above and the var ASubstrs section?

Thanks!

You don't need this at all. It just supplied a string to test with.
You wrote "I have a string ...". I had none, so I had to get one

2) I noticed the ...... , is there more that goes between the code
above and the var ASubstrs section?

No, I only wanted to indicate that the line above is not actually a
part of the code that implements the substring extraction.

So, if my string looks like:

"Crm-its-datateam Boise" <[email protected]>
and I wanted to capture just the info in the < > ???

Let's assume you hold your string in a variable named
"myNiceVar" and want to assign the substring to a
variable named "myOtherVar", then use:

var aSubstrs = myNiceVar.match(/"[^"]+"\s+<([^>]+)>/),
myOtherVar = aSubstrs && aSubstrs[1];

A shorter variant is:

var myOtherVar = [].concat(myNiceVar.match(/"[^"]+"\s+<([^>]+)>/))[1];
