Regexp to get the utm values

I'm looking to extract some of the utm values from a URL using regexp. My URL would look something like the below - 

utm_source=ko_1d5b57661294a3154&utm_medium=internetq&utm_campaign=-android5436af9f1aef91a654a7255038&utm_term=searchthis&utm_content=mainpage&

Is there any way to have a regexp that would extract all the utm values such as utm_source, utm_medium, utm_capaign, utm_term, utm_content ?

Another one according to utm_

/[^utm_=]\w+(?=&)/g

You could grab all patching pairs and then convert it to an object.

NOTE: The object conversion is simplistic (doesn't account for multiple params of the same key, etc.).

var regexp = /(?!&)utm_[^=]*=[^&]*(?=&)/g;

var query = 'utm_source=ko_1d5b57661294a3154&utm_medium=internetq&utm_campaign=-android5436af9f1aef91a654a7255038&utm_term=searchthis&utm_content=mainpage&';

var matches = query.match(regexp);
var values = matches.reduce(function(obj, param) {
  var keyVal = param.split('=');
  obj[keyVal[0]] = keyVal[1];
  return obj;
}, {});

document.write('<pre>' + JSON.stringify({
  matches: matches,
  values: values
}, null, 2) + '<pre>');

You could use a positive lookbehind for this case. The pattern would look like that:

(?<=utm_[a-z]+=)\w+

This pattern matches any alphanumerical characters that are preceeded by "utm_???="
