1、js文件:
// pages/shoplist/shoplist.js Page({ /** * 页面的初始数据 */ data:{ query:{}, "list":[ { "id":"1", "name":"apple", "image":"/shoplist_images/apple.png", "address":"砖井村", "tel":"18601416781" }, { "id":"2", "name":"avocado", "image":"/shoplist_images/avocado.png", "address":"砖井村", "tel":"186" }, { "id":"3", "name":"avocado_1", "image":"/shoplist_images/avocado_1.png", "address":"砖井村", "tel":"186" }, { "id":"4", "name":"banana", "image":"/shoplist_images/banana.png", "address":"砖井村", "tel":"186" }, { "id":"5", "name":"barbecue", "image":"/shoplist_images/barbecue.png", "address":"砖井村", "tel":"186" }, { "id":"6", "name":"beer", "image":"/shoplist_images/beer.png", "address":"砖井村", "tel":"186" }, { "id":"7", "name":"beer_mug", "image":"/shoplist_images/beer_mug.png", "address":"砖井村", "tel":"186" }, { "id":"8", "name":"birthday_cake", "image":"/shoplist_images/birthday_cake.png", "address":"砖井村", "tel":"186" }, { "id":"9", "name":"bone", "image":"/shoplist_images/bone.png", "address":"砖井村", "tel":"186" }, { "id":"10", "name":"bottle", "image":"/shoplist_images/bottle.png", "address":"砖井村", "tel":"186" }, { "id":"11", "name":"bowl", "image":"/shoplist_images/bowl.png", "address":"砖井村", "tel":"186" }, { "id":"12", "name":"bread", "image":"/shoplist_images/bread.png", "address":"砖井村", "tel":"186" }, { "id":"13", "name":"bread_2", "image":"/shoplist_images/bread_2.png", "address":"砖井村", "tel":"186" }, { "id":"14", "name":"cake_1", "image":"/shoplist_images/cake_1.png", "address":"砖井村", "tel":"186" }, { "id":"15", "name":"cake_2", "image":"/shoplist_images/cake_2.png", "address":"砖井村", "tel":"186" }, { "id":"16", "name":"cake_3", "image":"/shoplist_images/cake_3.png", "address":"砖井村", "tel":"186" }, { "id":"17", "name":"cake_4", "image":"/shoplist_images/cake_4.png", "address":"砖井村", "tel":"186" }, { "id":"18", "name":"cake_5", "image":"/shoplist_images/cake_5.png", "address":"砖井村", "tel":"186" }, { "id":"19", "name":"candy", "image":"/shoplist_images/candy.png", "address":"砖井村", "tel":"186" }, { "id":"20", "name":"canned_fruit", "image":"/shoplist_images/canned_fruit.png", "address":"砖井村", "tel":"186" }, { "id":"21", "name":"carrot", "image":"/shoplist_images/carrot.png", "address":"砖井村", "tel":"186" }, { "id":"22", "name":"chafing_dish_2", "image":"/shoplist_images/chafing_dish_2.png", "address":"砖井村", "tel":"186" }, { "id":"23", "name":"chafing_dish", "image":"/shoplist_images/chafing_dish.png", "address":"砖井村", "tel":"186" }, { "id":"24", "name":"cheese", "image":"/shoplist_images/cheese.png", "address":"砖井村", "tel":"186" }, { "id":"25", "name":"chef_hat", "image":"/shoplist_images/chef_hat.png", "address":"砖井村", "tel":"186" }, { "id":"26", "name":"cherry", "image":"/shoplist_images/cherry.png", "address":"砖井村", "tel":"186" }, { "id":"27", "name":"chicken", "image":"/shoplist_images/chicken.png", "address":"砖井村", "tel":"186" }, { "id":"28", "name":"chicken_leg", "image":"/shoplist_images/chicken_leg.png", "address":"砖井村", "tel":"186" }, { "id":"29", "name":"crab", "image":"/shoplist_images/crab.png", "address":"砖井村", "tel":"186" }, { "id":"30", "name":"fish", "image":"/shoplist_images/fish.png", "address":"砖井村", "tel":"186" }, { "id":"31", "name":"hamburger", "image":"/shoplist_images/hamburger.png", "address":"砖井村", "tel":"186" }, { "id":"32", "name":"hot_pot", "image":"/shoplist_images/hot_pot.png", "address":"砖井村", "tel":"186" }, { "id":"33", "name":"lemon", "image":"/shoplist_images/lemon.png", "address":"砖井村", "tel":"186" }, { "id":"34", "name":"popcorn", "image":"/shoplist_images/popcorn.png", "address":"砖井村", "tel":"186" }, { "id":"35", "name":"popcorn_2", "image":"/shoplist_images/popcorn_2.png", "address":"砖井村", "tel":"186" }, { "id":"36", "name":"snacks", "image":"/shoplist_images/snacks.png", "address":"砖井村", "tel":"186"}], i:0,//表示当前item项个数 shoplist:[], result:[], isloading:false }, /** * 生命周期函数--监听页面加载 */ onLoad(options) { this.setData ({ query:options }) this.getshoplist() }, getshoplist() { //当页面加载完毕时停止继续发出请求 if(this.data.i>this.data.result.length) { return wx.showToast({ title: '数据加载完毕!', icon:'none' }) } //防止多次下滑触底从而发出多次请求 this.setData({isloading:true}), wx.showLoading({ title: '数据加载中...', }) this.data.shoplist=this.data.list.slice(this.data.i,this.data.i+10) this.setData({ i:this.data.i + 10 }) this.data.result=this.data.result.concat(this.data.shoplist) this.setData({ result:this.data.result }) wx.hideLoading() this.setData({isloading:false}) }, /** * 生命周期函数--监听页面初次渲染完成 */ onReady() { wx.setNavigationBarTitle({ title: this.data.query.title, }) }, /** * 生命周期函数--监听页面显示 */ onShow() { }, /** * 生命周期函数--监听页面隐藏 */ onHide() { }, /** * 生命周期函数--监听页面卸载 */ onUnload() { }, /** * 页面相关事件处理函数--监听用户下拉动作 */ onPullDownRefresh() { }, /** * 页面上拉触底事件的处理函数 */ onReachBottom() { if(this.data.isloading) return this.getshoplist() }, /** * 用户点击右上角分享 */ onShareAppMessage() { } })
2、json文件
{ "usingComponents": {}, "onReachBottomDistance": 200 }
3、wxml文件
<!--pages/shoplist/shoplist.wxml--> <view wx:for="{{result}}" wx:key="id" class="shop-item"> <image src="{{item.image}}" class="thumb"></image> <view class="shop-item-item"> <view class="shop-title">商品名:{{item.name}}</view> <view>店铺地址:{{item.address}}</view> <view>联系电话:{{item.tel}}</view> </view> </view>
4、wxss文件
/* pages/shoplist/shoplist.wxss */ .shop-item{ display:flex; border: 1rpx solid rgb(216, 194, 194); border-radius: 50rpx; margin: 15rpx; box-shadow: 1rpx 1rpx 15rpx rgb(146, 102, 102); } .thumb { width: 320rpx; height: 320rpx; display: block; margin-right: 15rpx; padding: 15rpx; } .shop-item-item { display: flex; flex-direction: column; justify-content: space-around; font-size: 30rpx; } .shop-title { font-weight: bold; }
