The use of .* will cause the regex to back track and use of () will create a backreference. So we can use this to capture the given string ^[^=]+=

You can create a group which will match all the words starting from the beginning till the =. You can then access the regex group as shown here.

Something like: ^(.*?)= Should yield the following group value: http://someurl.com?someparameter. If you would like to include the =, then, just do as follows: ^(.*?=)

Up front: If you're parsing URLs, you might want to use one of the existing URL parsers or URI.js.

The beginning of a string is denoted by ^ so your RegEx could look like ^([^=]+). This matches everything but = from the beginning of the string. If you only want the part after the ?, try \?([^=]+). Note that you'll only get the very first parameter this way.

Have a look at MDN explaining RegExp.

This pattern should match until =:

.+?=
