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">

<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>
