【问题描述】:
我正在尝试建立一个单页网站来展示印度的 covid 病例。基本 url 返回一个按字母顺序排序的数组。我想根据“totalConfirmed”对其进行排序。这是我的代码。
<!DOCTYPE html>
<html lang="en">
<head>

<title>Covid19 India</title>

<div class="container mt-4" id="app">
<table class="table-responsive">
<table class="table">
<thead>

<th scope="col">Location</th>
<th scope="col">Total</th>
<th scope="col">Active</th>
<th scope="col">Recovered</th>
<th scope="col">Deaths</th>
</tr>
</thead>
<tbody>
<tr v-for="state, index in states">
<th scope="row">{{ index + 1 }}</th>
<td>{{ state.loc }}</td>
<td>{{ state.totalConfirmed }}</td>
<td>{{ state.totalConfirmed - (state.discharged + state.deaths)}}</td>
<td>{{ state.discharged }}</td>
<td>{{ state.deaths }}</td>
</tr>
</tbody>
</table>
</table>
</div>
<script>
const cases = [];
var app = new Vue({
el: '#app',
data: {
states: []
},
mounted: function() {
axios.get('https://api.rootnet.in/covid19-in/stats/latest')
.then(response => {
this.states = response.data.data.regional;
this.states = cases;
cases = _.orderBy(cases, 'totalConfirmed', 'desc');
console.log(cases);
})
.catch(error => {
console.log(error);
});
}
})
</script>
</body>
</html>
在我的控制台中,我收到一个错误“TypeError:_.orderBy 不是函数”。我在这里做错了什么?如果我不使用 orderBy,我的代码运行良好,没有错误。

这能回答你的问题吗? use Lodash to sort array of object by value
