我正在尝试从JSON文件中获取产品数据,但无法使其正常工作。 我已经尝试了几件事,并在互联网上搜索了解决方案,但是互联网上的所有示例都不符合我的情况。 我是vue和axios的新手,所以请原谅我的无知。
这是我到目前为止所拥有的:
Vue.component('products',{
data: {
results: []
},
mounted() {
axios.get("js/prods.json")
.then(response => {this.results = response.data.results})
},
template:`
<div id="products">
<div class="productsItemContainer" v-for="product in products">
<div class="productsItem">
<div class="">
<div class="mkcenter" style="position:relative">
<a class="item">
<img class="productImg" width="120px" height="120px" v-bind:src="'assets/products/' + product.image">
<div class="floating ui red label" v-if="product.new">NEW</div>
</a>
</div>
</div>
<div class="productItemName" >
<a>{{ product.name }}</a>
</div>
<div class="mkdivider mkcenter"></div>
<div class="productItemPrice" >
<a>€ {{ product.unit_price }}</a>
</div>
<div v-on:click="addToCart" class="mkcenter">
<div class="ui vertical animated basic button" tabindex="0">
<div class="hidden content">Koop</div>
<div class="visible content">
<i class="shop icon"></i>
</div>
</div>
</div>
</div>
</div>
</div>
`
})
new Vue({
el:"#app",
});
json文件如下
{
"products":[
{
"name": "Danser Skydancer",
"inventory": 5,
"unit_price": 45.99,
"image":"a.jpg",
"new":true
},
{
"name": "Avocado Zwem Ring",
"inventory": 10,
"unit_price": 123.75,
"image":"b.jpg",
"new":false
}
]
}
问题仅在于从JSON文件中获取数据,因为以下方法有效:
Vue.component('products',{
data:function(){
return{
reactive:true,
products: [
{
name: "Danser Skydancer",
inventory: 5,
unit_price: 45.99,
image:"a.jpg",
new:true
},
{
name: "Avocado Zwem Ring",
inventory: 10,
unit_price: 123.75,
image:"b.jpg",
new:false
}
],
cart:0
}
},
template: etc.........
答案 0 :(得分:1)
如警告所示,请执行以下操作:
results
重命名为products
,因为您在渲染过程中将后者作为名称引用。Vue.component('products', {
data() {
return {
products: []
}
},
mounted() {
axios
.get("js/prods.json")
.then(response => {
this.products = response.data.products;
});
},
template: `
//...
`
}
<div id="products">
<div class="productsItemContainer" v-for="product in products">
<div class="productsItem">
...
此外,由于您未使用CDN(我认为),因此建议您将模板制作为具有单独Vue文件的组件,而不是在模板文字中进行操作,例如:
<template>
<div id="products">
<div class="productsItemContainer" v-for="product in products">
<div class="productsItem">
<!-- The rest of the elements -->
</div>
</div>
</div>
</template>
<script>
export default {
name: 'Products',
data() {
return {
products: []
}
},
mounted() {
axios
.get("js/prods.json")
.then(response => {
this.products = response.data.products;
});
}
}
</script>
然后在您的主JS文件中或需要此组件的其他任何地方:
import Products from './components/Products.vue';
new Vue({
el: '#app',
data() {
return {
//...
}
},
components: {
Products
}
})
<div id="app">
<Products />
</div>
