微信小程序实现简单计算器

微信小程序写的简单计算器，供大家参考，具体内容如下

jisaunqi.js

// pages/jisuanqi/jisuanqi.js
Page({

/**
* 页面的初始数据
*/
data: {
result:"0",
string:"",
cal:"",
num1:"",
num2:""
},
btSubmit:function(e){
console.log(e);
var num1 = this.data.num1;
var cal = this.data.cal;
var num2 = this.data.num2;
var char= e.target.id;
var string ;
if((char>="0"&&char<="9"||char=='.')&&cal==""){
num1=num1+char;
this.setData({
num1:num1,
})
}
else if((char>="0"&&char<="9"||char=='.')&&cal!=""){
num2=num2+char;
this.setData({
num2:num2,
})
}
else {
cal=char;
this.setData({
cal:cal,
})
}
this.setData({
string:num1+cal+num2
})
},
clean:function(e){
this.setData({
string:"",
num1:"",
num2:"",

})
},

var num1 = this.data.num1;

var cal = this.data.cal;
var result;
switch(cal){
case '+':result=num1*1+num2*1;break;
case '-':result=num1*1-num2*1;break;
case '*':result=(num1*1)*(num2*1);break;
case '/':result=(num1*1)/(num2*1);break;
}
num1=result;
cal="";

this.setData({

num2:num2
})
},

var num2 = this.data.num2;
if(cal==""){num1="-";}
else if(cal!=""){num2="-"}
this.setData({

num2:num2
})
},
lololo:function(e){
console.log(123)
},
