input disable input expression! !

 Requirements: Users can only enter Chinese, English, numbers, symbols

Because too many Emoji expression code, it can not be completely filtered, only positive thinking:

Numerals and symbols portion

inputEmoji(e, from) {
      var val = e.target.value;
      var reg = /[^a-zA-Z0-9_\u4e00-\u9fa5\u3002\uff1b\uff0c\uff1a\u201c\u201d\uff08\uff09\u3001\uff1f\u300a\u300b/,.!:()?/_""-——]/g;
      if (from === 'name') {
        this.name = val.replace(reg, '');
      } else {
        this.introduction = val.replace(reg, '');
      }
    }
