基于vue2.0实现仿百度前端分页效果附实现代码

<Paging 
   :name="name"
   @change="onPageChange"
   :page-size="size"
   :total="total"
   layout="jumper,total"
   :current-page="curPage"
  />

props: ['title', 'likes', 'isPublished', 'commentIds', 'author']

props: {
 title: String,
 likes: Number,
 isPublished: Boolean,
 commentIds: Array,
 author: Object
}

props: {
  // 基础的类型检查 (`null` 匹配任何类型)
  propA: Number,
  // 多个可能的类型
  propB: [String, Number],
  // 必填的字符串
  propC: {
   type: String,
   required: true
  },
  // 带有默认值的数字
  propD: {
   type: Number,
   default: 100
  },
  // 带有默认值的对象
  propE: {
   type: Object,
   // 对象或数组默认值必须从一个工厂函数获取
   default: function () {
    return { message: 'hello' }
   }
  },
  // 自定义验证函数
  propF: {
   validator: function (value) {
    // 这个值必须匹配下列字符串中的一个
    return ['success', 'warning', 'danger'].indexOf(value) !== -1
   }
  }
 }
