Trim Function

j1500 · Jul 5, 2006

I need to trim the values inbetween the () parens in the following string. The number of characters between the parens may vary so I basically need to search for the beginning ( and ending ) and extract the value.

5609010.1151607160.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none)

Please provide any guidance you may have. I noticed JavaScript does not have a trim function.

what do you mean? do you mean you need to remove spaces from either side of the values within parentheses?

See this is a cookie value and I only want the value (whatever it may be; in this case it is direct) inbetween the parens of 'utmccn='.

So, I need a function which would return "direct" extracted from the string below:

5609010.1151607160.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none)

well, here's an example, using a regular expression. this will work, however depending on the complexity of your cookie string, you may need to tweak the regex a little...

Code:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>
<head>
	<title>Untitled</title>
<script type="text/javascript"><!--

var cookie = "5609010.1151607160.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none)";
var ma = cookie.match( /(\S+)\((\w+)\)(\S+)\((\w+)\)(\S+)\((\w+)\)/ );

alert(RegExp.$2);
alert(RegExp.$4);
alert(RegExp.$6);

//--></script>
</head>

<body>

</body>
</html>

Here's an alternate version of Cory's code that will handle a dynamic number of values.

Code:

<script type="text/javascript"><!--

var cookie = "5609010.1151607160.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none)";
var ma = cookie.match( /[^\(\)]+(?=\))/gi );

for(var i=0; i<ma.length;i++){
  alert(ma[i]);
}

//--></script>
