Vue手机计算器 Vue实现手机计算器
昵称~ 人气:0想了解Vue实现手机计算器的相关内容吗,昵称~在本文为您仔细讲解Vue手机计算器的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:vue,计算器,下面大家一起来学习吧。
1.首先是把样式做出来,按钮是0-9,还有加减乘除,百分号,清除按钮,小数点,等号、等等
2.把官方网站的JS插件引用,cn.vuejs.org/v2/guide/

JS
new Vue({ el: "#app", data: { equation: '0', isDecimalAdded: false, //防止在一组数字中间输入超过一个小数位 isOperatorAdded: false, //判断之否已点击 加、减、乘、除,防止连续点击超过一个运算符号 isStarted: false, //判断计算器是否已经开始输入数字,用于正负数和百分比计算的时候作一些判断 }, methods: { //Check if the character is + - × ÷ isOperator(character) { //用来判断character 是否加减乘除 return ['+', '-', '×', '÷'].indexOf(character) > -1 }, append(character) { //append(character)加减乘除 if (this.equation === '0' && !this.isOperator(character)) { if (character === '.') { this.equation += '' + character this.isDecimalAdded = true } else { this.equation = '' + character } this.isStarted = true return } if (!this.isOperator(character)) { if (character === '.' && this.isDecimalAdded) { return } if (character === '.') { this.isDecimalAdded = true this.isOperatorAdded = true } else { this.isOperatorAdded = false } this.equation += '' + character } if (this.isOperator(character) && !this.isOperatorAdded) { this.equation += '' + character this.isDecimalAdded = false this.isOperatorAdded = true } }, calculate() { //等于号的时候 let result = this.equation.replace(new RegExp('×', 'g'), '*').replace(new RegExp('÷', 'g'), '/') this.equation = parseFloat(eval(result).toFixed(9)).toString() this.isDecimalAdded = false this.isOperatorAdded = false }, calculateToggle() { //点击正负号 if (this.isOperatorAdded || !this.isStarted) { true } this.equation = this.equation + '* -1' this.calculate() }, calculatePercentage() { //点击百分比 if (this.isOperatorAdded || !this.isStarted) { true } this.equation = this.equation + '* 0.01' this.calculate() }, clear() { //点击AC this.equation = '0' this.isDecimalAdded = false //防止在一组数字中间输入超过一个小数位 this.isOperatorAdded = false //判断之否已点击 加、减、乘、除,防止连续点击超过一个运算符号 this.isStarted = false //判断计算器是否已经开始输入数字,用于正负数和百分比计算的时候作一些判断 } } })
