export default {
  data() {
    return {
      value: '123',
      showKeyboard: true,
      errorInfo: ''
    };
  },
  methods: {
    onInput(key) {
      this.value = (this.value + key).slice(0, 6);
      if (this.value.length === 6) {
        this.errorInfo = 'Password Mistake';
      } else {
        this.errorInfo = '';
      }
