JS字符串去重

code如下

//设置没有重复的nextOperatorCode
setTruecode(){
   console.info(this.nextOperatorCode,111);

   //先按照逗号分割字符串
   let arrycode  =  this.nextOperatorCode.split(",");
   console.info(arrycode,222);

   //去重
   arrycode = Array.from(new Set(arrycode));
   console.info(arrycode,333);

   //拼接正确的nextOperatorCode
   this.nextOperatorCode = arrycode = arrycode.toLocaleString();
   console.info( this.nextOperatorCode,444);

}

log如下

admin,lisi,zhangsan,admin,lisi,zhangsan 111

["admin", "lisi", "zhangsan", "admin", "lisi", "zhangsan"] 222

["admin", "lisi", "zhangsan"] 333

admin,lisi,zhangsan 444
