for example, I have a dynamic string like 1232 {Button 1} {Button 2} 765432 (variable length). How can I get 1231 and {Button 1}, {Button 2}, 765432?

var a='1232{1}{2}765432'
console.log(a.replace(/{/,',{').replace(/}/g,'},').split(','),'9999'); output
1232 {Button 1} {Button 2} 765432 then / ^ (\ d +) (\ {Button\ d\}) (\ {Button\ d\}) (\ {Button\ d\}) (\ d+) (\ d+) $/ can get each part from the captured submatches. For example,
var re=/^(\d+)(\{\d\})(\{\d\})(\d+)$/;
var rtall=re.exec("1232{1}{2}765432");
console.log(rtall);let str = "1232{1}{2}765432"
