微信小程序商城项目的示例分析(微信小程序,web开发)

页面分析：

使用for循环遍历所有项，插入页面，页面中的项使用左浮动，并使用百分比布局，设置20%的宽度每一项。
这样满5个item后，自动排在下一行

wxml：

<viewclass="menu-wrp"><!--设定一个item项后，遍历输出--><viewclass="menu-list"wx:for="{{menu.imgUrls}}"><imageclass="menu-img"src="{{item}}"/><viewclass="menu-desc">{{menu.descs[index]}}</view></view></view><viewclass="gap-1"></view>

wxss：

.menu-wrp{width:100%;margin-top:20rpx;}.menu-wrp:after{content:"";display:block;clear:both;}.menu-list{float:left;width:20%;box-sizing:border-box;padding-bottom:10px;}.menu-img{width:120rpx;height:84rpx;display:block;margin:0auto;margin-bottom:5px;}.menu-desc{background-color:#ffffff;color:#333333;width:100%;text-align:center;display:block;font-size:12px;}.gap-1,.gap-2{width:100%;height:10rpx;background:rgb(238,238,238);}

js：

这里的准备的数据，我直接写在js中，同学们可以改编成通过访问接口来获取

Page({data:{//准备数据menu:{imgUrls:['https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/tqa0otd5pe3.png?imgtag=avatar','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/4shm1c1p51x.png?imgtag=avatar','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/ofyds5nadgg.png?imgtag=avatar','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/fhc5sqknhin.png?imgtag=avatar','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/fgqaqemrts0.png?imgtag=avatar','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/15vldmijgty.png','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/ik0lyyilm1g.png','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/0q3oful3ogz.png?imgtag=avatar','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/ft5bh3nozph.png','https://qixn-bj.oss-cn-beijing.aliyuncs.com/seosjz/uploadfile/all/png/yvxnv3fkpld.png?imgtag=avatar'],descs:['聚划算','天猫','天猫国际','外卖','天猫超市','充值中心','阿里旅行','领金币','到家','分类']}}})
