RegEx in JavaScript - Start with and Ends with

Question

I want to extract a string using RegEx in Javascript for example

StudentName nameX = John;

or

StudentName nameX;

I want to extract only "nameX" this is what i've tried so far.

var name = allName.match("StudentName(.*);|StudentName(.*)=");

what I'm getting is : "nameX = John" , but I'm not getting "nameX" only.

Use regex pattern inside of match

match(/StudentName\s+(\w+)/)[1]

See this demo.

Thanks, that works. is there a way to find all the objects? for example, if you have StudentName nameX; StudentName nameY; StudentName nameZ; can you find all of nameX,y and z ? Thanks

@kkDev - To find all occurrences use re = new RegExp() and while loop with match = re.exec() condition. Google for it :)

Try this non greedy pattern

var name = allName.match("StudentName\\s*(.*?)\\s*[=;]");

If you split on blank spaces then the second match at index 1 should contain the name.

var name = allName.split(/[ ;]/g)[1];
