Javascript reg ex returns only one occurence

I have a string like this 

[Key1]+[Key2]+[Key3]

My following regular expression returns [Key1]+[Key2]+[Key3]

var re = new RegExp("\\[.+\\]", "g");
var arr = re.exec("[Key1]+[Key2]+[Key3]");

But I want to get [Key1], [Key2], [Key3]... all the available matches. How can I achive that?

Use the non greedy modifier:

var re = new RegExp("\\[.+?\\]", "g");
//                 here __^

re.exec gives only the first match, if you want all the matches, you have to use string.match(re):

var string = "[Key1]+[Key2]+[Key3]"; 
var re = new RegExp("\\[.+?\\]", "g");
var arr = string.match(re);

then arr contains ["[Key1]", "[Key2]", "[Key3]"]

var str = "[Key1]+[Key2]+[Key3]"; 
var res = str.match(/\[.+?\]/g);

res contains an array of matches, you can use res.join(",") in order to obtain your string
