写项目的时候发现小程序没有自带的弹窗输入的组件，只能自己写一个。

1.半透明的遮盖层

遮盖层的样式和显隐事件

wxml代码：

<view class="body"> <button bindtap='eject'>弹窗</button></view><view class="model" catchtouchmove='preventTouchMove' wx:if='{{showModal}}'></view>

wxss代码：

.model{ position: absolute; width: 100%; height: 100%; background: #000; z-index: 999; opacity: 0.5; top: 0; left:0;}

js代码：

/** * 页面的初始数据 */ data: { showModal: false, }, /** * 控制遮盖层的显示 */ eject:function(){ this.setData({ showModal:true }) }

2.弹窗窗口实现

弹窗窗口的样式和显隐事件

wxml代码：

<view class="modalDlg" catchtouchmove='preventTouchMove' wx:if='{{showModal}}'> <view class='windowRow'> <text class='userTitle'>标题 </text> <view class='back' bindtap='back'> 返回 </view> </view> <view class='wishName'> <input bindinput='wish_put' placeholder='请输入内容' class='wish_put'></input> </view> <view class='wishbnt'> <button class='wishbnt_bt' bindtap='ok'>确定</button> </view></view>

wxss代码：

.modalDlg{ width: 70%; position: fixed; top:350rpx; left: 0; right: 0; z-index: 9999; margin: 0 auto; background-color: #fff; border-radius: 10rpx; display: flex; flex-direction: column; align-items: center;}.windowRow{ display: flex; flex-direction: row; justify-content: space-between; height: 110rpx; width: 100%;}.back{ text-align: center; color: #f7a6a2; font-size: 30rpx; margin: 30rpx;}.userTitle{ font-size: 30rpx; color: #666; margin: 30rpx;}.wishName{ width: 100%; justify-content: center; flex-direction: row; display: flex; margin-bottom: 30rpx;}.wish_put{ width: 80%; border: 1px solid; border-radius: 10rpx; padding-left: 10rpx;}.wishbnt{ width: 100%; font-size: 30rpx; margin-bottom: 30rpx;}.wishbnt_bt{ width: 50%; background-color: #f7a6a2; color: #fbf1e8; font-size: 30rpx; border: 0;}

js代码：

/** * 页面的初始数据 */ data: { showModal: false, textV:'' }, /** * 控制显示 */ eject:function(){ this.setData({ showModal:true }) }, /** * 点击返回按钮隐藏 */ back:function(){ this.setData({ showModal:false }) }, /** * 获取input输入值 */ wish_put:function(e){ this.setData({ textV:e.detail.value }) }, /** * 点击确定按钮获取input值并且关闭弹窗 */ ok:function(){ console.log(this.data.textV) this.setData({ showModal:false }) }

3.完整代码

最后献上完整代码，有点啰嗦了，想尽量详细点

wxml代码：

<view class="body"> <button bindtap='eject'>弹窗</button></view><view class="model" catchtouchmove='preventTouchMove' wx:if='{{showModal}}'></view><view class="modalDlg" catchtouchmove='preventTouchMove' wx:if='{{showModal}}'> <view class='windowRow'> <text class='userTitle'>标题 </text> <view class='back' bindtap='back'> 返回 </view> </view> <view class='wishName'> <input bindinput='wish_put' placeholder='请输入内容' class='wish_put'></input> </view> <view class='wishbnt'> <button class='wishbnt_bt' bindtap='ok'>确定</button> </view></view>

wxss代码：

.body{ width: 100%; height: 100%; background-color: #fff; position: fixed; display: flex;}.body button{ height: 100rpx;}.model{ position: absolute; width: 100%; height: 100%; background: #000; z-index: 999; opacity: 0.5; top: 0; left:0;}.modalDlg{ width: 70%; position: fixed; top:350rpx; left: 0; right: 0; z-index: 9999; margin: 0 auto; background-color: #fff; border-radius: 10rpx; display: flex; flex-direction: column; align-items: center;}.windowRow{ display: flex; flex-direction: row; justify-content: space-between; height: 110rpx; width: 100%;}.back{ text-align: center; color: #f7a6a2; font-size: 30rpx; margin: 30rpx;}.userTitle{ font-size: 30rpx; color: #666; margin: 30rpx;}.wishName{ width: 100%; justify-content: center; flex-direction: row; display: flex; margin-bottom: 30rpx;}.wish_put{ width: 80%; border: 1px solid; border-radius: 10rpx; padding-left: 10rpx;}.wishbnt{ width: 100%; font-size: 30rpx; margin-bottom: 30rpx;}.wishbnt_bt{ width: 50%; background-color: #f7a6a2; color: #fbf1e8; font-size: 30rpx; border: 0;}

js代码：

Page({ /** * 页面的初始数据 */ data: { showModal: false, textV:'' }, /** * 控制显示 */ eject:function(){ this.setData({ showModal:true }) }, /** * 点击返回按钮隐藏 */ back:function(){ this.setData({ showModal:false }) }, /** * 获取input输入值 */ wish_put:function(e){ this.setData({ textV:e.detail.value }) }, /** * 点击确定按钮获取input值并且关闭弹窗 */ ok:function(){ console.log(this.data.textV) this.setData({ showModal:false }) }})
