如题

<view class='ul'>     <view class='u_1' bindtap='jian'>-</view>     <input type='digit' placeholder='{{yemian.num_t}}' value='{{yemian.num}}' bindfocus='focus' bindblur='blur'></input>     <view class='u_2' bindtap='jia'>+</view> </view> Page({     data: {         yemian: {             num: '0',             num_t: '',         }     },     onLoad: function() {},     //加操作     jia: function () {         var that = this;         var yemian = that.data.yemian;         if (yemian.num == '') {             yemian.num = yemian.num_t;         }         yemian.num = (parseInt(yemian.num) + 1).toString();         that.setData({             yemian: yemian,         });     },     //减操作     jian: function () {         var that = this;         var yemian = that.data.yemian;         if (yemian.num == '0') return;             yemian.num = (parseInt(yemian.num) - 1).toString();         that.setData({             yemian: yemian,         });     },          ///获取焦点事件     focus: function (e) {         var that = this;         var yemian = that.data.yemian;         yemian.num_t = yemian.num;         yemian.num = '';         that.setData({             yemian: yemian         });     },     //失去焦点事件     blur: function (e) {         var that = this;         var yemian = that.data.yemian;         if (e.detail.value == '') {             yemian.num = yemian.num_t;         } else {             yemian.num = e.detail.value.toString()         }         that.setData({             yemian: yemian         });     } }) [图片]     当input焦点未离开input时，点击+（view），理想值是101，但实际是100，如果仔细看的话应该是101瞬间变为100，     附加问题：         yemian.num = 200;         yemian.num_t = yemian.num;                  改 yemian.num = 0;         yemian.num_t 的值也随之改为0         为什么？？？？？？          

...... onLoad: function(options) {         var user = wx.getStorageSync('user');         wx.request({             url: app.url + '/Api/GetDefault',             data: {                     yh_id: user.id,                     yh_tel: user.mobile             },             method: 'post',             success: res => {                 if (res.data.isok == 'yes') {                     yemian=res.data.info;                     this.setData({                         yemian: yemian                     });                 }             }         }) }, ...... onReady: function() {     var yemian = this.data.yemian;     console.log(yemian); }, 问题：执行onload 中的 wx.request，返回值用setData渲染到wxml页面，onReady 是获取setData渲染完毕之后的值还是之前的值              

[图片] 是我代码写错了 还是 。。。 求解

修复来修复去，黑屏问题还没解决

代码格式化是这样的： if (flag == 1 && yemian.shop_price == '0.00') {     if (yemian.member_price != '0.00') {         yemian.shop_price = yemian.member_price;     } else if (yemian.retail_price != '0.00') {         yemian.shop_price = yemian.retail_price;     } } 可不可以做成这样： if (flag == 1 && yemian.shop_price == '0.00') {     if (yemian.member_price != '0.00')     {         yemian.shop_price = yemian.member_price;     }     else if (yemian.retail_price != '0.00')     {         yemian.shop_price = yemian.retail_price;     } } 这样感觉很清晰

在开发工具开发当中，经常性的粘贴复制不可以用，遇到好几个版本都这样，可不可以将此问题解决

因为我们的小程序是用于公司的库存管理，需要对接我们库存管理软件，在管理软件中授权才能使用小程序，需要在管理软件中绑定手机使用者的手机号码并且与微信绑定的手机号匹配才能使用小程序。如果贵方需要测试，请提供测试者的手机号，我们后台进行绑定

先说下做了一个信息发布的小程序，需要自动定位显示当前区域的信息，在onload 中 用wx.getLocation定位到当前区域，再执行wx.request查询信息。 问题： 在wx.getLocation还没有执行返回数据之前，wx.request已经执行完毕
