你好,请问你解决了吗
微信小程序调用百度云图像识别api,上线后却无法识别?开发时用的云开发,调用百度云EasyDL图像识别接口用来识别垃圾种类,按照步骤调取后,在微信开发者工具上真机调试识别成功,上线后在手机端识别图像的时候却无法识别。
2021-12-22又有新问题了,当利率设为小数时,利息输出结果为null,懵了
请各位大神帮忙看看,新手不会了,这是什么原因造成的?新手刚学微信小程序,想做个这个题目: 设计一个小程序输入本金、利率。默认本金10000,利率3%,5年后得到多少钱? 但做完发现利息计算正确但结果却总是初始本金与利息拼接的一个数字就这样: [图片] 这是代码,麻烦大佬看看问题出在哪里: index.js Page({ /** * 页面的初始数据 */ data: { flag: true, name: '', principal: '', interest_rate: '', access_period: '', interest:'', Total_principal_after_deposit_and_withdrawal_period:'' }, nameInput: function (e) { this.setData({ name: e.detail.value }); }, principalInput: function (e) { this.setData({ principal: e.detail.value }); }, interest_rateInput: function (e) { this.setData({ interest_rate: e.detail.value }); }, access_periodInput: function (e) { this.setData({ access_period: e.detail.value }); }, mysubmit: function () { var benjin = this.data.principal; var lilu = this.data.interest_rate; var lixi = 0; for(var i = 1;i <= this.data.access_period; i++ ){ lixi += benjin*lilu; benjin = benjin + lixi; } this.setData({ Total_principal_after_deposit_and_withdrawal_period: benjin, interest: lixi, flag: false }); } } ) index.wxml <view class='box'> <view class='title'>利息计算器</view> <input placeholder="请输入你的名字" placeholder-class="placeholder" bindinput='nameInput'></input> <input placeholder="请输入本金" placeholder-class="placeholder" bindinput='principalInput' type='number'></input> <input placeholder="请输入利率" placeholder-class="placeholder" bindinput='interest_rateInput' type='number'></input> <input placeholder="请输入存取年期" placeholder-class="placeholder" bindinput='access_periodInput' type='number'></input> <button bindtap='mysubmit'>提交</button> <view hidden='{{flag}}' class='content'> <view class='content-item'>姓名:{{name}}</view> <view class='content-item'>每月本金:{{principal}}</view> <view class='content-item'>利率:{{interest_rate}}</view> <view class='content-item'>所得利息总计:{{interest}}</view> <view class='content-item'>存取年限后总本金:{{Total_principal_after_deposit_and_withdrawal_period}}</view> </view> </view>
