分页组件是每一个系统里必不可少的一个组件,分页组件分为两部分。第一部分是模版部分,用于显示当前分页组件的状态,例如正在获取数据、没有数据、没有下一页等等;第二部分是分页数据对象,用于封装一个分页组件的属性和方法,例如获取数据的 url、当前第几页(page)、每次加载条数(count)、一共有多少页(totalPage)等等,方法可能会有上一页、下一页、处理数据等等。
import base from '@/api/base'
export default class Pagination {
constructor({ url, processFunc, processExt, count = 10, isMock = false }) {
// 数据访问地址
this.url = url
// 数据集合
this.list = []
// 第几页
this.page = 1
// 一共几页
this.totalPage = 1
// 加载数据条数
this.count = count
// 数据处理函数
this.processFunc = processFunc
// 错误处理函数
this.processExt = processExt
// 正在加载中
this.loading = false
// 参数
this.params = {}
// 是否底部
this.reachBottom = false
// 是否为空
this.empty = true
// 是否需要清除
this.toClear = false
// 是否为mock数据
this.isMock = isMock
}
/**
