Regex Match Value In Typescript

I am trying to extract the value of certain pattern from the text. Sample text: Test: [] subtests: [a] I want to extract the line subtests: [a] or precisely what's the data insid

Solution 1:

Here is a Working Fiddle. So the only change was to remove the captures ie: changing (.*) to .*

Explaining your problem..

This regex ^subtests: (.*) has captures in it. And when you find the matches for this regex, it gives you a set of all the regex matches and then all the capture's. So the first set is subtests: [] and then the set of captures that is []. Hence your output was subtests: [],[] (note the ,).

Solution 2:

Here is a live demo. Forked and modified from your source. https://jsfiddle.net/soonsuweb/aj38617b/

var data = `blur blur subtests: [] blur\nblur`;
var regex = /subtests: \[.*\]/;
var test = regex.exec(data);
alert("Op: " + test);
