Vue实现手机计算器

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

1. new Vue({
2. el: "#app",
3. data: {
4. equation: '0',
5. isDecimalAdded: false, //防止在一组数字中间输入超过一个小数位
6. 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
7. 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
8. },
9. methods: {
10. //Check if the character is + - × ÷
11. isOperator(character) { //用来判断character 是否加减乘除
12. return ['+', '-', '×', '÷'].indexOf(character) > -1
13. },
14. append(character) { //append(character)加减乘除
15. if (this.equation === '0' && !this.isOperator(character)) {
16. if (character === '.') {
17. this.equation += '' + character
18. this.isDecimalAdded = true
19. } else {
20. this.equation = '' + character
21. }
22. this.isStarted = true
23. return
24. }
25.  
26. if (!this.isOperator(character)) {
27. if (character === '.' && this.isDecimalAdded) {
28. return
29. }
30.  
31. if (character === '.') {
32. this.isDecimalAdded = true
33. this.isOperatorAdded = true
34. } else {
35. this.isOperatorAdded = false
36. }
37. this.equation += '' + character
38. }
39.  
40. if (this.isOperator(character) && !this.isOperatorAdded) {
41. this.equation += '' + character
42. this.isDecimalAdded = false
43. this.isOperatorAdded = true
44. }
45. },
46. calculate() { //等于号的时候
47. let result = this.equation.replace(new RegExp('×', 'g'), '*').replace(new RegExp('÷', 'g'), '/')
48. this.equation = parseFloat(eval(result).toFixed(9)).toString()
49. this.isDecimalAdded = false
50. this.isOperatorAdded = false
51. },
52. calculateToggle() { //点击正负号
53. if (this.isOperatorAdded || !this.isStarted) {
54. true
55. }
56.  
57. this.equation = this.equation + '* -1'
58. this.calculate()
59. },
60. calculatePercentage() { //点击百分比
61. if (this.isOperatorAdded || !this.isStarted) {
62. true
63. }
64.  
65. this.equation = this.equation + '* 0.01'
66. this.calculate()
67. },
68. clear() { //点击AC
69. this.equation = '0'
70. this.isDecimalAdded = false //防止在一组数字中间输入超过一个小数位
71. 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
72. 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
73. }
74. }
75. })
