我想通过调用api使用axios显示每个ID(1、2、3)的总视图,如下所示:
<f7-block>
<f7-col
:key="index"
v-for="(items, index) in list">
Total views: {{countView(items.id)}}
</f7-col>
export default {
data(){
list: [];
// list = [{id: 1}, {id: 2}, {id: 3}]
},
methods(){
async countView(id){
let url = 'xxx';
let filter = {
where: {
quizId: id
}
}
try{
let res = await axios.get(url, filter);
return res.data.countViews;
} catch(error) {
}
}
}
}
如何使用vue异步数据来显示视图数,而不是 {} ?

有一种更好的方法,为每个项目创建一个自定义组件。然后在每个自定义组件中调用countView
:
TotalView.vue
<template>
<span v-if="count !== null">
{{ count }}
</span>
</template>
<script>
export default {
name: 'TotalView'
props: ['itemId'],
data: () => ({
count: null
}),
created() {
this.countView(this.itemId)
},
methods: {
async countView(id){
let url = 'xxx';
let filter = {
where: {
quizId: id
}
}
try{
let res = await axios.get(url, filter);
this.count = res.data.countViews
} catch(error) {
}
}
}
}
</script>
并在您的组件中使用它:
<f7-block>
<f7-col
:key="index"
v-for="(items, index) in list">
Total views: <total-view :itemId="items.id" />
</f7-col>
