我是靠谱客的博主标致黑猫，这篇文章主要介绍quasar + vue3 composition api 使用refs内方法以及使用挂载api(axios)的方法记录quasar + vue3 composition api 初步应用，现在分享给大家，希望可以做个参考。

quasar + vue3 composition api 初步应用

你好！这记录一次初步应用学习quasar + vue3 Composition api,应用场景是 $a p i ($ axios)挂载,但是不使用Options API的情况。

应用例子

以下为学习应用例子,通过getCurrentInstance 获取proxy,来使用挂载的 $a p i ($ axios),以及refs内的方法,仅供参考(估计写法不是很规范)：

复制代码

<template>
<div class="flex flex-start q-pa-md non-selectable">
<q-infinite-scroll @load="getList" :reverse="false" :offset="5"
class="infinite-panel" ref="infiniteScroll">
<template v-slot:loading>
<div class="row justify-center q-my-md">
<q-spinner color="primary" name="dots" size="40px" ></q-spinner>
</div>
</template>
<q-timeline color="secondary">
<q-timeline-entry title="" :subtitle="news.createTime" v-for="(news,i) in newsList" :key="i">
<a href="news.sourceUrl">{{news.sourceUrl}}</a>
<div style="white-space: pre-wrap;">{{news.text}}</div>
<div style="white-space: pre-wrap;">{{news.textCn}}</div>
<div v-for="(item,index) in news.urlList" :key="`${index + '*'}`">
{{item}}
</div>
</q-timeline-entry>
</q-timeline>
</q-infinite-scroll>
</div>
</template>
<script>
import { defineComponent, ref, reactive, onMounted, getCurrentInstance } from "vue";
export default defineComponent({
name: "twitterNews",
setup() {
let { proxy } = getCurrentInstance()
let newsList = reactive([])
//获取list
const getList = (index, done) => {
proxy.$api({
method: "get",
url: "twitters/list" + `?current=${index}`,
})
.then((res) => {
if(res.data.code === 0){
newsList.push(...res.data.data.records);
if(res.data.data.records.length === 0){
try {
proxy.$refs.infiniteScroll.stop()
} catch (error) {}
}
}
done()
})
.catch((e) => {
console.log(e)
done()
});
}
onMounted(()=>{
})
return {
newsList,
getList
};
},
});
</script>
<style scoped>
.infinite-panel{
height: calc(100% - 80px);
}
.infinite-panel > ul {
margin-top:0;
margin-bottom:0;
}
</style>

}
.infinite-panel > ul {

margin-bottom:0;
}
</style>

以下再提供一种可能较为规范和普遍的 $a p i ($ axios)通过引入使用,然后通过ref来使用refs的方法,如下:
