js正则的问题

正则


let str = `\loves{小猫}{鱼}
  \loves2{小猫1}{鱼2}
 `;


 let reg2 = new RegExp(`(\\([\s\S]*?))(\{)([\s\S]*?)(\})(\{)([\s\S^\{\}]*?)(\})(\{)([\s\S]*?)(\})`);

 let arr = reg2.exec(str);
        

结果

> arr [
  '\loves{小猫}{鱼}
        \loves2{小猫1}{鱼2}',
  '\loves',
  'loves',
  '{',
  '小猫',
  '}',
  '{',
  '鱼}
        \loves2{小猫1',
  '}',
  '{',
  '鱼2',
  '}',
  index: 0,
  input: '\loves{小猫}{鱼}
        \loves2{小猫1}{鱼2}
        ',
  groups: undefined
]

本来我是想匹配 这样的 love{}{}{}

我希望括号里面不要再有 { 或者 } 符号。

应该怎么写正则呢

(这个排版我反复编辑了四五次,实在调不好)

没有你想的那么复杂吧

let reg2=/\\[^{]*?({[^{
]*})+/

或者

let reg2=/\\[^{]*?{([^{
]*)}[^{]*?{([^{
]*)}[^{]*?$/
