<swiper circular indicator-dots>#circular
使轮播图循环播放 indicator-dots
用于显示指示点
</swiper>(最后
<block wx:for="{{list}}" wx:key="index">#从list中获得轮播项
<swiper-item>
<image src="{{item.imgUrl}}" />
</swiper-item>#在每一个轮播图里从item.imgUrl中获取
</block>
<view class="button" bind:tap="onClick">
<image src="{{icon_url}}" />=(一个小图标)
<view class="text" style="{{style}}">{{content}}</view>#content内容 动态绑定style
</view>#一个里面有字的按钮

imageList.where({
db.collection("imageList").where({
这两个语句在有const imageList= db.collection("imageList")后等价onClick() { let number = []; while (number.length < 4) { let randomNum = Math.floor(Math.random() * 10); if (!number.includes(randomNum)) { number.push(randomNum);}} 作用是生成一个随机数之后取整 如果不在的话就塞进number里面 一共找4个 console.log(number)#打印前面的number research = db.command#定义一个research 以下是各种生命周期函数: onLoad(options) {},#监听页面加载 onReady() {},#监听页面初次渲染完成 onShow() {},#监听页面显示 onHide() {},#监听页面隐藏 onUnload() {},监听页面卸载 onPullDownRefresh() { this.onClick()#调用onClick setTimeout(()=>{wx.stopPullDownRefresh()},2000)#延迟2s执行stopPullDownRefresh函数 onReachBottom() {},#触底 onShareAppMessage() {}#分享
