通常,菜单都有一级菜单二级、三级菜单之分,我们知道前端js的dom操作可以很好的控制二级菜单的显示与隐藏,当然今天我就不介绍web端的菜单折叠效果。我今天呢,是来学习学习小程序中该如何实现点击一级菜单显示/隐藏二级菜单,并且在点击一个菜单显示之外,要实现其他菜单隐藏。
实现效果如下:
代码如下:
.wxml文件
{{item.cont}} {{item.discount}} {{items.price}} {{items.oldPrice}} {{items.validType}} {{items.validTime}} 购买
.wxss文件如下:
page{ background: #fff; } .swiper-img{ width: 750rpx; height: 300rpx; } .cells .item .cdn{ position: relative; box-sizing:border-box; display: flex; justify-content: space-between; align-items: center; padding: 20rpx 30rpx; /*border-bottom: 1rpx solid #f0f0f0;*/ background-color: #fff; font-size: 32rpx; } .cells .item .cdn::after{ content:'';position:absolute;top:0;left:0;width:200%;height:200%;-webkit-transform:scale(.5);transform:scale(.5);-webkit-transform-origin:0 0;transform-origin:0 0;pointer-events:none;box-sizing:border-box;border-bottom:0 solid #f0f0f0;border-width:1px } .img{ height: 44rpx; width: 44rpx; vertical-align: middle; display: inline-block; line-height: 82rpx; } .icon_img{ height:12rpx; width:20rpx; } .content{ margin-left: 15rpx; line-height: 82rpx; vertical-align: middle; } .discount{ line-height: 82rpx; vertical-align: middle; color:orange; box-sizing: border-box; padding-right: 20rpx; } .video-item{ display: flex; flex-direction: column; } .buys{ width:750rpx; height: 141.6rpx; position: relative; box-sizing: border-box; padding: 20rpx 30rpx; display: flex; flex-direction: row; justify-content: space-between; align-items: center; background-color:#FAFAFA; } .buys::after { content:'';position:absolute;top:0;left:0;width:200%;height:200%;-webkit-transform:scale(.5);transform:scale(.5);-webkit-transform-origin:0 0;transform-origin:0 0;pointer-events:none;box-sizing:border-box; border-bottom:0 solid #DCDCDC;border-width:1px; } .v1{ width: 35%; display: flex; flex-direction: row; flex-wrap: wrap; } .new-price{ font-size: 32rpx; color: #3B3B3B; } .oldPrice{ text-decoration:line-through; font-size: 24rpx; color: #B0B0B0; margin-left: 20rpx; } .buy{ font-size: 24rpx; color: #2DAF73; text-align: center; width: 80rpx; height: 40rpx; line-height: 40rpx; display: inline-block; position: relative; box-sizing: border-box; } .buy::after{ content:'';position:absolute;top:0;left:0;width:200%;height:200%;-webkit-transform:scale(.5);transform:scale(.5);-webkit-transform-origin:0 0;transform-origin:0 0;pointer-events:none;box-sizing:border-box;border:0 solid #2DAF73;border-width:1px;border-radius:8rpx } .shopping{ width: 128rpx; height: 56rpx; line-height: 56rpx; position: relative; box-sizing: border-box; font-size: 28rpx; color: #2DAF73; text-align: center; } .shopping::after{ content:'';position:absolute;top:0;left:0;width:200%;height:200%;-webkit-transform:scale(.5);transform:scale(.5);-webkit-transform-origin:0 0;transform-origin:0 0;pointer-events:none;box-sizing:border-box;border:0 solid #2DAF73;border-width:1px;border-radius:16rpx }
