input组件在开发者工具上一切正常，但在手机预览时，将光标放在最前面，点击删除键 e.detail.value变为空，代码如下: //  wxml <input bindinput="countValChange" name="account" placeholder="请输入账号或绑定的手机号" /> // js [代码]Page({  data: {    inputValue: ''  },[代码][代码]  countValChange: function(e) {  [代码] [代码]    // 手机预览时，将光标放在最前面，点击删除键，在vconsole上打印出的结果是空  [代码] [代码]    console.log([代码]e.detail.value[代码])[代码] [代码]    this.setData({[代码] [代码]      inputValue: e.detail.value[代码][代码]    }) [代码] [代码]  } })[代码]

项目是用wepy生成的，出现一个问题：input组件在工具上调试正常，但在手机上预览或者体验版时，将光标移到最前面，点击删除，e.detail.value变为了空，不知道什么情况。。。。 [图片] [图片] [图片] 代码如下: <template> <view class="container"> <form bindsubmit="formSubmit" bindreset="formReset"> <view class="title">请输入孩子的账号和密码 </view> <view class="section"> <input bindinput="countValChange" name="account" placeholder="请输入孩子的账号或绑定的手机号" /> </view> <view class="section"> <input bindinput="psdValChange" name="password" placeholder="请输入密码" password="{{!showPsd}}" /> <view class="imgWrap" bindtap="showPsd"> <image wx:if="{{!showPsd}}" src="../static/password1.png" /> <image wx:if="{{showPsd}}" src="../static/password2.png" /> </view> </view> <view class="btn-area" wx-if="{{isSub}}"> <button formType="submit">关联账号</button> </view> <view class="btn-area notSub" wx-if="{{!isSub}}"> <button>关联账号</button> </view> </form> </view> </template> <script> import wepy from 'wepy' import { connect } from 'wepy-redux' import { SET_BIND_STATUS } from '../store/types/user' @connect({ bindStatus (state) { return state.user.bindStatus } }, { setBindStatus: SET_BIND_STATUS }) export default class ChildInput extends wepy.page { config = { navigationBarTitleText: '关联孩子账号' } components = {} data = { showPsd: false, count: '', psd: '' } methods = { formSubmit (e) { // 后台交互 console.log('form发生了submit事件，携带数据为：', e.detail.value) this._bindAccount(e.detail.value.account, e.detail.value.password) // 弹窗 // wepy.showToast({ //   title: '成功', //   icon: 'none', //   duration: 2000 // }) }, showPsd() { this.showPsd = !this.showPsd }, countValChange(e) { this.count = e.detail.value console.log(this.count) }, psdValChange(e) { this.psd = e.detail.value console.log(this.psd) } } _bindAccount (account, password) { // let that = this wx.request({ url: `${this.$parent.globalData.baseURL}/wx/micro/parent/bindStu`, method: 'POST', header: { 'Content-Type': 'application/x-www-form-urlencoded', 'S_T': wx.getStorageSync('token') }, data: { userName: account, password: password }, success (res) { console.log('child-input.wpy --> _bindAccount --> success') console.log(res) if (res.data.ret_code === 0) { wx.showToast({ title: '关联成功', icon: 'success', duration: 1400, success () { setTimeout(() => { wx.navigateBack({delta: 1}) }, 1400) } }) } else { wx.showToast({icon: 'none', title: res.data.ret_msg, duration: 1400}) } }, fail (res) { console.log('child-input.wpy --> _bindAccount --> success') console.log(res) wx.showToast({icon: 'none', title: '关联孩子失败', duration: 1400}) } }) } computed = { isSub() { if (this.count && this.psd) { return true } else { return false } } } onLoad() {} } </script> <style lang="less"> .container{ width: 690rpx; margin: 0 auto; form{ width: 100%; height: auto; } .title{ margin: 30rpx 0; font-size: 40rpx; font-weight: 900; padding: 0; } .section{ height: 90rpx; width: 100%; border-bottom: 1rpx solid #cccccc; margin-top: 20rpx; position: relative; input{ height: 100%; line-height: 90rpx; } .imgWrap{ width: 48rpx; height: 48rpx; display: black; padding: 15rpx; position: absolute; top: 0; right: 15rpx; z-index: 99; image{ width: 48rpx; height: 48rpx; } } } .btn-area{ margin-top: 50rpx; button{ color: #ffffff; background: #007AFF; } } .notSub button{ background: #cccccc; color: #999999; } } </style>
