微信小程序picker组件下拉框选择input输入框的实例
实现效果图：
页面
<view> <view>预约项目</view> <picker bindchange="bindCasPickerChange" value="{{casIndex1}}" range="{{casArray}}"> <view> <text>{{casArray[casIndex]}}</text> </view> </picker> </view> </view> <view> <input placeholder="请输入所预约项目" type="text"/> </view>
js
data: { nickName: "", avatarUrl: "", casArray: ['双眼皮', 'TBM', '隆胸', '减肥', '手动输入'], userName: '', mobile: '', Gender: 'female', casIndex: 0, }, /** * 生命周期函数--监听页面加载 */ bindCasPickerChange: function (e) { console.log('乔丹选的是', this.data.casArray[e.detail.value]) if (e.detail.value == 4) { this.setData({ reply: true }) } else { this.setData({ reply: false }) } this.setData({ casIndex: e.detail.value }) },
添加input框的样式
.section{ font-size:28rpx; margin-left: 50rpx; margin-top: 30rpx; } .on{display: block} .off{display: none}
