这是我第一次使用Vue.js。我制作了这个应用程序,它使用了我在脚本中手动添加的数据。现在,我希望能够添加一个从中获取数据的JSON文件,但是我不知道该怎么做。在下面可以找到我的代码。
HTML:
<div id="app">
<div class="search-wrapper">
<input type="text" v-model="keyword" placeholder="Zoek telefoon..." />
</div>
<div class="wrapper">
<table style="width:100%; text-align: left;">
<tr>
<th style="text-align: left; width: 33%">Telefoon</th>
<th style="text-align: left; width: 33%">Scherm</th>
<th style="text-align: left; width: 33%">Batterij</th>
</tr>
</table>
<div v-for="post in filteredList">
<table style="width:100%; text-align: left">
<tr style="text-align: left;">
<td style="text-align: left; width: 33%">{{ post.title }}</td>
<td style="text-align: left; width: 33%">{{ post.scherm }}</td>
<td style="text-align: left; width: 33%">{{ post.batterij }}</td>
</tr>
</table>
</div>
</div>
Vue.js:
var app = new Vue({
el: '#app',
data: {
keyword: '',
postList: [
{ title: 'A', scherm: '35', batterij: '15' },
{ title: 'B', scherm: '65', batterij: '25' },
{ title: 'C', scherm: '40', batterij: '35' },
{ title: 'D', scherm: '35', batterij: '75' },
{ title: 'E', scherm: '20', batterij: '45' },
],
},
computed: {
filteredList() {
return this.postList.filter((post) => {
return post.title.toLowerCase().includes(this.keyword.toLowerCase());
});
}
}
});
编辑:
我的代码现在看起来像这样,但是现在只返回{{ post.title }}
等。

<td style="text-align: left; width: 33%">{{ post.batterij }}</td>
</tr>
</table>
</div>
</div>
脚本:
import posts from "../posts.json";
el: '#app',
data: {
keyword: '',
postList: [],
},
computed: {
filteredList() {
return this.postList.filter((post) => {
return post.title.toLowerCase().includes(this.keyword.toLowerCase());
});
}
},
mounted(){
axios
.get('posts.json')
.then(response => (this.postList = response.data))
}
}
JSON(posts.json):
[
{ title: "Samsung Galaxy S9", scherm: "35", batterij: "15" },
{ title: "Huawei P10", scherm: "65", batterij: "25" },
{ title: "iPhone X", scherm: "40", batterij: "35" },
{ title: "Huawei P20 Lite", scherm: "35", batterij: "75" },
{ title: "Samsung A9", scherm: "20", batterij: "45" },
]

Vue cli :
将数据设置在名为posts.json
的文件中,并按如下所示进行导入:
import posts from "./posts.json";
并将其分配到postList
钩子中的mounted
上:
computed:{
....
},
mounted(){
this.postList=posts
}
CDN
在这种情况下,您应该使用axios这样的AJAX API
computed:{
....
},
mounted(){
axios
.get('posts.json')
.then(response => (this.postList = response.data))
}
}
,并且您应包括以下脚本:
<script src="https://unpkg.com/vue@2.5.17/dist/vue.js"></script>
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<script src="https://unpkg.com/vue-axios@2.1.4/dist/vue-axios.min.js"></script>
完整示例
var app = new Vue({
el: '#app',
data: {
keyword: '',
postList: []
},
computed: {
filteredList() {
return this.postList.filter((post) => {
return post.title.toLowerCase().includes(this.keyword.toLowerCase());
});
}
},
mounted(){
axios.get('https://jsonplaceholder.typicode.com/posts')
.then((response)=> {
this.postList=response.data;
})
}
});
