Invalid prop: type check failed for prop "maxLength". Expected Number, got String.

背景今天使用Ant Design of Vue的input表单的maxlength属性报错了 

<a-input
      :value="value"
      placeholder="Input a number"
      maxLength="100"
      style="width: 120px"
      @change="onChange"
      @blur="onBlur"
    />

解决

maxLength="100"

改为

:maxLength="100"

或

:max-length="100"

就OK了。
