Javascript Capturing Groups

Question

I am struggling with capturing and non-capturing groups in Javascript.

I have the following string

var string = "#Blah blah blah\n#ENV:This is env note 1\n#MISC:this is a misc note\n#ENV:this is env note 2\n\n";

I would like to capture each text that starting with #ENV: and ending with new line, without capturing the '#ENV:' tag itself. (ie I want to return ["this is env note 1", "this is env note 2"]

I have tried the following:

var capture = string.match(/(?:#ENV)([^\n]*)/gi);
// Returns: ["#Blah blah blah", "#ENV:This is env note 1", "#MISC:this is a misc note", "#ENV:this is env note 2"]

var capture2 = string.match(/(?:(#ENV))([^\n]*)/gi);
//Returns ["#ENV:This is env note 1", "#ENV:this is env note 2"]

Any advice is greatly appreciated.

Thanks

Answer 1

两个正则表达式具有相同的结果，您必须从结果中剪切#ENV:

Answer 2

Found solution.

Problem comes from match method.

The following code works instead

var regex = /#ENV:(.*?)\n/gi;
var match;
var result=[];
while(match = regex.exec(string)) {result.push(match[1]);}
