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

一、项目中，使用element-ui的input表单的maxlength属性报错

二、使用场景： 

      <el-input v-model="fname"  maxlength='100'></el-input>

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

 

      解决方法：

      <el-input v-model="fname"  :maxlength='100'></el-input>

三、minlength同理
