}

}
export {HTTP}
 
使用
 
import { HTTP } from '../../utils/http.js'

class ListModel extends HTTP {
getAllvd() {
return this.request({
url: 'm=laodou&c=videolist'
})
}
getMorevd(s) {
return this.request({
url: 'm=laodou&c=videolist&start=' + s
})
}
}
export { ListModel }
 
使用
 
import {
ListModel
} from 'videolist-model.js'
import {
config
} from '../../config.js'
const listModel = new ListModel()
Page({

/**
   * 页面的初始数据
   */
data: {
vddataArray: []
},
 
onLoad: function(e) {
this._loadData()
},
_loadData(e) {
wx.showLoading({
title: '加载中…',
})
const listvd = listModel.getAllvd()
Promise.all([listvd]).then(res => {
//console.log(res)
res[0][0].isPlaying = !0
this.vddataArray = res[0]
this.setData({
feeds: res[0],
})
wx.hideLoading()
wx.stopPullDownRefresh()
})
},

const s = this.vddataArray.length
console.log(s)
const listmorevd = listModel.getMorevd(s)
Promise.all([listmorevd]).then(res => {
console.log(res[0])
const tempdataArray = this.vddataArray.concat(res[0])
console.log(tempdataArray)
this.vddataArray = tempdataArray
this.setData({
feeds: tempdataArray
})
})
},
onReady: function() {},
onShow: function() {},
onHide: function() {},
onUnload: function() {},
onPullDownRefresh: function() {
