我无法将this pen移动到Vue.js
这就是我的代码对于Vue应用程序的样子 - 我理解HTML和CSS应该去哪里。我应该将Javascript添加到单个组件,还是将其添加到App.vue文件中?
我想要做的是在我可以路由到的视图中测试此代码。
这是笔中的Javascript:
var app = new Vue({
el: '#app',
mounted() {
let vm = this
axios
.get(
'https://sheets.googleapis.com/v4/spreadsheets/15qFEW97T-9Im9dx5G4KJqRorPDy74wwAvqaQm5Phz4w/values/A2%3AC12?key=AIzaSyBP4OwJmDCdX0rdOdgIa4q79g0XrMGcOSk'
)
.then(function (response) {
let specials = response.data.values
for (let index = 0; index < specials.length; index++) {
const element = specials[index]
let mitem = {
name: element[0],
description: element[1],
price: element[2]
}
if (vm.isEven(index)) {
vm.menuItems_L = vm.menuItems_L.concat(mitem)
} else {
vm.menuItems_R = vm.menuItems_R.concat(mitem)
}
}
console.log(response)
})
},
data: {
menuItems_L: [],
menuItems_R: [],
menuStyle: {
background: '#ffe6d1',
color: '#000'
},
dotStyle: {
backgroundImage: 'radial-gradient(' + this.color + ' 1px, transparent 0px)'
}
},
computed: {},
methods: {
isEven: function (n) {
return n % 2 == 0
}
}
});
这就是我的代码在组件中的样子(通过研究/猜测的变化),HTML在它上面的标签中:
<script>
import axios from 'axios';
export default {
mounted() {
let vm = this
Vue.axios.get(
'https://sheets.googleapis.com/v4/spreadsheets/15qFEW97T-9Im9dx5G4KJqRorPDy74wwAvqaQm5Phz4w/values/A2%3AC12?key=AIzaSyBP4OwJmDCdX0rdOdgIa4q79g0XrMGcOSk'
)
.then(function (response) {
let specials = response.data.values
for (let index = 0; index < specials.length; index++) {
const element = specials[index]
let mitem = {
name: element[0],
description: element[1],
price: element[2]
}
if (vm.isEven(index)) {
vm.menuItems_L = vm.menuItems_L.concat(mitem)
} else {
vm.menuItems_R = vm.menuItems_R.concat(mitem)
}
}
console.log(response)
})
},
data: {
menuItems_L: [],
menuItems_R: [],
menuStyle: {
background: '#ffe6d1',
color: '#000'
},
dotStyle: {
backgroundImage: 'radial-gradient(#000, 1px, transparent 0px)'
}
},
computed: {},
methods: {
isEven: function (n) {
return n % 2 == 0
},
setColor: function (c) {
c = menuStyle.color
let colorStyle = 'radial-gradient(' + c + ' 1px, transparent 0px)'
return colorStyle
}
}
}
</script>
你只需要删除第一个HTML模板上的链接,并使<div id='#app'>
是整个页面的根,如Vue Docs所述
Vue将显示错误,解释每个组件必须具有单个根元素。您可以通过将模板包装在父元素中来修复此错误
同时将data:{}
更改为data(){return{}}
...因为正如Vue Docs所述,数据必须是函数
组件的数据选项必须是一个函数,以便每个实例都可以维护返回的数据对象的独立副本:
import axios from 'axios';
export default {
el: '#app',
data() {
return {
menuItems_L: [],
menuItems_R: [],
menuStyle: {
background: '#ffe6d1',
color: '#000'
},
dotStyle: {
backgroundImage: 'radial-gradient(' + this.color + ' 1px, transparent 0px)'
}
}
},
mounted() {
let vm = this
axios
.get(
'https://sheets.googleapis.com/v4/spreadsheets/15qFEW97T-9Im9dx5G4KJqRorPDy74wwAvqaQm5Phz4w/values/A2%3AC12?key=AIzaSyBP4OwJmDCdX0rdOdgIa4q79g0XrMGcOSk'
)
.then(function (response) {
let specials = response.data.values
for (let index = 0; index < specials.length; index++) {
const element = specials[index]
let mitem = {
name: element[0],
description: element[1],
price: element[2]
}
if (vm.isEven(index)) {
vm.menuItems_L = vm.menuItems_L.concat(mitem)
} else {
vm.menuItems_R = vm.menuItems_R.concat(mitem)
}
}
console.log(response)
})
},
methods: {
isEven: function (n) {
return n % 2 == 0
}
}
}
