商城复用
-
-
- 1，加减乘除精度计算，亲测好使！
- 2，结算页面data
-
- 3，订单页面展示（商城太多，记录下来复用，持续更新~）
- app.vue我写了全局css
-
1，加减乘除精度计算，亲测好使！
- 新建calculation.js文件
- 页面导入使用import culation from “@/common/calculation.js”
- 使用。类似culation.accMul(数值1, 数值2)
function accAdd(num1, num2) {
var p1 = 0;
var p2 = 0;
if (num1.toString().split('.').length > 1) {
p1 = num1.toString().split('.')[1].length;
}
if (num2.toString().split('.').length > 1) {
p2 = num2.toString().split(".")[1].length;
}
var n1 = num1 * Math.pow(10, 2);
var n2 = num2 * Math.pow(10, 2);
var result = (n1 + n2).toFixed(2) / Math.pow(10, 2);
return result;
}
function accSub(num1, num2) {
var p1 = 0;
var p2 = 0;
if (num1.toString().split('.').length > 1) {
p1 = num1.toString().split('.')[1].length;
}
if (num2.toString().split('.').length > 1) {
p2 = num2.toString().split(".")[1].length;
}
var n1 = num1 * Math.pow(10, 2);
var n2 = num2 * Math.pow(10, 2);
var result = (n1 - n2).toFixed(2) / Math.pow(10, 2);
return result;
}
function accMul(num1, num2) {
let result = num1 * num2
if (Number.isInteger(result)) {
return result
} else {
return Math.round(result * 100) / 100
}
}
function accDiv(a, b) {
let result = num1/num2
if (Number.isInteger(result)) {
return result
} else {
return Math.round(result * 100) / 100
}
}
export default {
accAdd,
accSub,
accMul,
accDiv
}
2，结算页面data
data() {
return {
carlist: [],
allChecked: false,
}
}
计算总金额
computed: {
allprice() {
let price = 0;
this.carlist.map(item => {
item.checked ? price += item.num * item.goods_price : price += 0
})
return price
}
},
单选
changecheck(item) {
item.checked = !item.checked
if (!item.checked) {
this.allChecked = false
} else {
const cartList = this.carlist.every(item => {
return item.checked === true
})
if (cartList) {
this.allChecked = true
} else {
this.allChecked = false
}
}
},
全选
selectAll() {
this.allChecked = !this.allChecked
if (this.allChecked) {
this.carlist.map(item => {
item.checked = true
})
} else {
this.carlist.map(item => {
item.checked = false
})
}
},
3，订单页面展示（商城太多，记录下来复用，持续更新~）
app.vue我写了全局css
<style lang="scss">
.flex {
display: flex;
}
.flexOne {
flex: 1;
}
.flexColumn {
flex-direction: column;
}
.wrap {
flex-wrap: wrap;
}
.noWrap {
flex-wrap: nowrap;
}
.alignCenter {
align-items: center;
}
.justifyCenter {
justify-content: center;
}
.alignBetween {
align-content: space-between;
}
.justifyBetween {
justify-content: space-between;
}
.alignStart {
align-items: flex-start;
}
.justifyStart {
justify-content: flex-start;
}
.alignEnd {
align-items: flex-end;
}
.justifyEnd {
justify-content: flex-end;
}
.justifyaround {
justify-content: space-around;
}
</style>
商城页面代码直接用
