How To Create Regex From Any Letter To A Specific Character

I have string like this: http://someurl.com?someparameter=dhws6sd6cvg and i would like to mach part from first letter to '=' with javascript regex. Is it possible?

Solution 1:

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: ^(.*?=)

Solution 2:

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.

Solution 3:

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 ^[^=]+=

Solution 4:

This pattern should match until =:

.+?=
