index.wxss

/**index.wxss**/
input{
  border: solid 2px;
  margin: 10rpx 0;
}

 index.js

// index.js
// 获取应用实例
const app = getApp()

Page({
  data: {
  username:null, 
  password:null,
  stepnum:null
  },
  start: function(){
    this.startsteps((rescode)=>{
      console.log(rescode);
      if(rescode==206||rescode==201){
        console.log(rescode);
        wx.showToast({
          title: '提交失败！', 
          icon: 'none',  
          duration: 1500  
        })
      };
      if(rescode==203){
        wx.showToast({
          title: '手机号格式错误！',  
          icon: 'none',  
          duration: 1500
        })
      };
      if(rescode==200){
        wx.showToast({
          title: '提交成功！', 
          icon: 'success',
          duration: 1500
        })
      }

  username:function(e){
    this.setData({
      username: e.detail.value
   });
  },

    this.setData({
      password: e.detail.value
   });
  },
  stepnum:function(e){
    this.setData({
      stepnum: e.detail.value
   });
  },
  
  startsteps:function(success){
    if(this.data.username==null){
      wx.showToast({
        title: '请输入账号！', 
        icon: 'none',  
        duration: 1500  
      })
    }
    else if(this.data.password==null){
      wx.showToast({
        title: '请输入密码！', 
        icon: 'none',  
        duration: 1500  
      })
    }
    else if(this.data.stepnum==null){
      wx.showToast({
        title: '请输入步数！', 
        icon: 'none',  
        duration: 1500  
      })
    }
    else{
    wx.request({
      url: 'https://接口域名/api.php',
      data: {user:this.data.username,password:this.data.password,step:this.data.stepnum},
      header: {'content-type':'application/json'},
      method: 'GET',
      dataType: 'json',
      responseType: 'text',
      success: (result) => {
        let rescode = result.data.code;
        success(rescode);
      },
      fail: () => {},
      complete: () => {}
    })
    }
  }

})

代码记录

小程序提示

 wx.showToast({
        title: '提示内容！', 
        icon: 'none',  //填写none显示感叹号，success显示对号
        duration: 1500  //消息显示停留时间
      })

获取文本框内容并赋值

<input bindinput="username" placeholder="请输入账号" />

data: {
    username:null,
},  

username:function(e){
    this.setData({
      username: e.detail.value
   });
},

this.data.username//调用该值

实现点击按钮事件

<button class="startbtn" bindtap="start">提交步数</button>

start: function(){
    this.startsteps((rescode)=>{
      //调用startsteps函数并获取返回值rescode
    });
},

startsteps:function(success){
    wx.request({
      url: 'https://域名/api.php',
      data: {user:this.data.username,password:this.data.password,step:this.data.stepnum},
      header: {'content-type':'application/json'},
      method: 'GET',
      dataType: 'json',
      responseType: 'text',
      success: (result) => {
        let rescode = result.data.code;//获取请求成功的code值
        success(rescode);
      },
      fail: () => {},
      complete: () => {}
    })
  }
