微信小程序data传参问题提问

Question

微信小程序函数如何传参，分析程序如何传参
Page({
data: {
num: '0',
op: '+'
},
result: null,
isClear: false,
//添加数字功能区
numbtn: function (e) {
var num = e.target.dataset.val
if (this.data.num === '0' || this.isClear) {
this.setData({
num: num
})
console.log("一this.isclear:" + this.isClear)
console.log("一num:" + num)
console.log("一this.data.num:" + this.data.num)
this.isClear = false
} else {
console.log("二this.data.num:" + this.data.num)
this.setData({
num: this.data.num + num //使用+拼接数字
})
console.log("二num:" + num)
console.log("二this.data.num:" + this.data.num)
}
},
//运算符号功能函数区
opbtn: function (e) {
var op = this.data.op
var num = Number(this.data.num)
console.log("三num:" + num)
//此段代码用于在荧幕上显示运算符
this.setData({
op: e.target.dataset.val
})
console.log("三op:" + op)
console.log("三this.isclear:" + this.isClear)
//避免多次按计算按钮重复计算
if (this.isClear) {
return
}
this.isClear = true
console.log("三this.result:" + this.result)
if (this.result === null) {
this.result = num
return
}
console.log("三this.result:" + this.result)
if (op === '+') {
this.result = this.result + num
} else if (op === '-') {
this.result = this.result - num
} else if (op === '*') {
this.result = this.result * num
} else if (op === '/') {
this.result = this.result / num
} else if (op === '%') {
this.result = this.result % num
}
console.log("三op:" + op)
//荧幕显示
this.setData({
num: this.result + ''
})
console.log("四num:" + num)
},

有事件获取控件的值，比如bindinput，或者放到form中添加bindsubmit获取所有控件值
