How do I get the contents of a string?

$str = "Hello, welcome to [ARGS1]. We will ship to you immediately, address: [ARGS2]";

How to get [ARGS1] and [ARGS2]; Is it normal to match?

The regular level is a bit rotten, /^(\[)*(\])$/ is there a problem with matching?
Please advise!

JavaScript Edition

With match

var str = '你好，欢迎使用[args1].我们会马上给你发货，地址:[args2]';var re = /\[\w+\]/g;var matches = str.match(re);console.log(matches[0],matches[1]);

With exec

var str = '你好，欢迎使用[args1].我们会马上给你发货，地址:[args2]';var re = /\[\w+\]/g;while((matches =re.exec(str)) != null){    console.log(matches[0]);}

It's complicated.

var str = '你好，欢迎使用[args1].我们会马上给你发货，地址:[args2]';var re = /[\u4e00-\u9fa5]/;console.log(str.split(re).filter(function(value){return /\[\w+\]/.test(value)}))

You also need to make a simple return array.
