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:"", cal:"" }) }, calculate:function(e){ var num1 = this.data.num1; var num2 = this.data.num2; 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=""; num2=""; this.setData({ result:result, num1:num1, cal:cal, num2:num2 }) }, reverse:function(e){ var cal = this.data.cal; var num1 = this.data.num1; var num2 = this.data.num2; if(cal==""){num1="-";} else if(cal!=""){num2="-"} this.setData({ num1:num1, num2:num2 }) }, lololo:function(e){ console.log(123) }, confirm:function(e){ console.log(555); console.log(e) }, event:function(e){ wx.navigateTo({ url: '/pages/event/event', }) }, bindinput:function(e){ console.log(1) }, jisuanqi:function(e){ var n1=e.detail.value.num1; var n2=e.detail.value.num2; var result=n1*1+n2*1; console.log(n1); console.log(n2); console.log(result); this.setData({ result:result }) }, tiaozhuan:function(e){ wx.navigateTo({ url: '/pages/9x9form/9x9form', }) }, /** * 生命周期函数--监听页面加载 */ onLoad: function (options) { }, /** * 生命周期函数--监听页面初次渲染完成 */ onReady: function () { }, /** * 生命周期函数--监听页面显示 */ onShow: function () { }, /** * 生命周期函数--监听页面隐藏 */ onHide: function () { }, /** * 生命周期函数--监听页面卸载 */ onUnload: function () { }, /** * 页面相关事件处理函数--监听用户下拉动作 */ onPullDownRefresh: function () { }, /** * 页面上拉触底事件的处理函数 */ onReachBottom: function () { }, /** * 用户点击右上角分享 */ onShareAppMessage: function () { } })
