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。
