Page({
 data: {
 number: 1,
 number1: 5,
 disabled1: false,
 disabled2: false
 },
 prevNum(){
 this.setData({ number: this.data.number + 1 });
 },
 nextNum(){
 this.setData({ number: this.data.number - 1 });
 },
 prevNum1() {
 this.setData({ 
  number1: this.data.number1 >= 10 ? 10 : this.data.number1 + 1 ,
  disabled1: this.data.number1 !== 0 ? false : true,
  disabled2: this.data.number1 !== 10 ? false : true
 });
 },
 nextNum1() {
 this.setData({ 
  number1: this.data.number1 <= 0 ? 0 : this.data.number1 - 1 ,
  disabled1: this.data.number1 !== 0 ? false : true,
  disabled2: this.data.number1 !== 10 ? false : true
 });
 }
})

注意

button组件的边框和圆角设置在button::after，需要对其重置。
