  replacement: '',
  val: '223'
}

HTML

<pattern-input class="your-class-name"
               :regExp="setting.regExp"
               :replacement="setting.replacement"
               @input="handleInput"
               @change="handleChange"
               v-model.number="setting.val"></pattern-input>

This setting will make user input positive integer only.

When you want get a Number, remember use v-model.number, and the safe maxlength is 15.
