本文实例为大家分享了Vue制作仿手机计算器的具体代码，供大家参考，具体内容如下
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/
页面视图
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

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.calculate()
