微信小程序select下拉框实现
小程序中是没有h5中的下拉 标签的 所以要实现下拉功能就必须自己动手写拉,这里为了更清楚的显示小程序层级 就把源码直接复制过来了
<view class=‘list-msg‘> <view class=‘list-msg1‘> <text>商品金额</text> <text>¥99.00</text> </view> <!--下拉框 --> <view class=‘list-msg2‘ bindtap=‘bindShowMsg‘> <text>{{tihuoWay}}</text> <image style=‘height:20rpx;width:20rpx;‘ src=‘/images/down.png‘></image> </view> <view class=‘list-msg1‘> <text>运费</text> <text></text>免邮</view> <view class=‘list-msg1‘> <text>实际付款</text> <text style=‘color:red‘>¥99.00</text> </view> <!-- 下拉需要显示的列表 --> <view class="select_box" wx:if="{{select}}"> <view class="select_one" bindtap="mySelect" data-name="重庆分店">重庆分店</view> <view class="select_one" bindtap="mySelect" data-name="东莞南城分店">东莞南城分店</view> <view class="select_one" bindtap="mySelect" data-name="东莞总店">东莞总店</view> </view> </view> 下面是js代码 Page({ /** * 页面的初始数据 */ data: { select: false, tihuoWay: ‘门店自提‘ }, /** * 生命周期函数--监听页面加载 */ onLoad: function (options) { }, bindShowMsg() { this.setData({ select:!this.data.select }) }, mySelect(e) { var name = e.currentTarget.dataset.name this.setData({ tihuoWay: name, select: false }) }, /** * 用户点击右上角分享 */ onShareAppMessage: function () { } }) .list-msg { padding: 0 20rpx; background-color: #fff; position: relative; } .list-msg1 { height: 60rpx; display: flex; align-items: center; justify-content: space-between; } .list-msg .list-msg2 { height: 60rpx; display: flex; align-items: center; justify-content: space-between; border: 1px solid #ccc; padding: 0 10rpx; } .select_box { background-color: #eee; padding: 0 10rpx; width: 93%; position: absolute; top: 130rpx; z-index: 1; overflow: hidden; animation: myfirst 0.5s; } @keyframes myfirst { from { height: 0rpx; } to { height: 210rpx; } } .select_one { height: 60rpx; line-height: 60rpx; border-bottom: 1px solid #ccc; }
