這篇文章給大家分享的是有關使用小程序寫一個彈窗輸入組件的案例的內容。小編覺得挺實用的,因此分享給大家做個參考,一起跟隨小編過來看看吧。
遮蓋層的樣式和顯隱事件
wxml代碼:
<view class="body"> <button bindtap='eject'>彈窗</button> </view> <view class="model" catchtouchmove='preventTouchMove' wx:if='{{showModal}}'></view>
wxss代碼:
.model{ position: absolute; width: 100%; height: 100%; background: #000; z-index: 999; opacity: 0.5; top: 0; left:0; }
js代碼:
/** * 頁面的初始數據 */ data: { showModal: false, }, /** * 控制遮蓋層的顯示 */ eject:function(){ this.setData({ showModal:true }) }
彈窗窗口的樣式和顯隱事件
wxml代碼:
<view class="modalDlg" catchtouchmove='preventTouchMove' wx:if='{{showModal}}'> <view class='windowRow'> <text class='userTitle'>標題 </text> <view class='back' bindtap='back'> 返回 </view> </view> <view class='wishName'> <input bindinput='wish_put' placeholder='請輸入內容' class='wish_put'></input> </view> <view class='wishbnt'> <button class='wishbnt_bt' bindtap='ok'>確定</button> </view> </view>
wxss代碼:
.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代碼:
/** * 頁面的初始數據 */ data: { showModal: false, textV:'' }, /** * 控制顯示 */ eject:function(){ this.setData({ showModal:true }) }, /** * 點擊返回按鈕隱藏 */ back:function(){ this.setData({ showModal:false }) }, /** * 獲取input輸入值 */ wish_put:function(e){ this.setData({ textV:e.detail.value }) }, /** * 點擊確定按鈕獲取input值并且關閉彈窗 */ ok:function(){ console.log(this.data.textV) this.setData({ showModal:false }) }
最后獻上完整代碼,有點啰嗦了,想盡量詳細點
wxml代碼:
<view class="body"> <button bindtap='eject'>彈窗</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'>標題 </text> <view class='back' bindtap='back'> 返回 </view> </view> <view class='wishName'> <input bindinput='wish_put' placeholder='請輸入內容' class='wish_put'></input> </view> <view class='wishbnt'> <button class='wishbnt_bt' bindtap='ok'>確定</button> </view> </view>
wxss代碼:
.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代碼:
Page({ /** * 頁面的初始數據 */ data: { showModal: false, textV:'' }, /** * 控制顯示 */ eject:function(){ this.setData({ showModal:true }) }, /** * 點擊返回按鈕隱藏 */ back:function(){ this.setData({ showModal:false }) }, /** * 獲取input輸入值 */ wish_put:function(e){ this.setData({ textV:e.detail.value }) }, /** * 點擊確定按鈕獲取input值并且關閉彈窗 */ ok:function(){ console.log(this.data.textV) this.setData({ showModal:false }) } })
