我正在尝试从axios调用中获取数组:
,以便我可以访问组件的数据。我知道我可以使用
之类的东西 return {
a: []
}
}
getTags(index) {
axios.get('http://localhost:8080/user/tag?imageIndex=' + index)
.then(response => {
this.a = response.data
})
},
但是问题是,我为每个图像都有一个数组,并且图像的数量是动态的。所以我只想给一个数组
是否有机会做我想做的事情? 如果可以动态地生成data()中的所有数组,我可以忍受。还是axios可以退回它?
这是我的无效代码:
<template>
<div id="SingleFile">
<button
id="refreshbtn"
class="btn btn-primary btn-margin"
@click="updateFileList">
refresh
</button>
<gallery :images="images" :index="index" @close="index = null"></gallery>
<div
:key="imageIndex"
:style="{ backgroundImage: 'url(' + image + ')', width: '300px', height: '200px' }"
@click="index = imageIndex"
class="image"
v-for="(image, imageIndex) in images"
>
<div>
<vue-tags-input
v-model="tag"
:tags="getTags(imageIndex)"
@tags-changed="newTags => tags = newTags"
/>
</div>
</div>
<div class="upload">
<upload-image url="http://localhost:8080/user" name="files" max_files="100"></upload-image>
</div>
</div>
</template>
<script>
import VueGallery from 'vue-gallery';
import axios from 'axios';
import auth from './../service/AuthService'
import router from './../router'
import UploadImage from 'vue-upload-image';
import VueTagsInput from '@johmun/vue-tags-input';
export default {
components: {
'gallery': VueGallery,
'upload-image': UploadImage,
VueTagsInput
},
data() {
return {
images: [],
index: null,
tag: '',
};
},
created() {
this.checkAuth()
},
methods: {
checkAuth() {
if (auth.isAuthenticated()) {
this.updateFileList()
} else {
router.replace('/')
}
},
updateFileList() {
axios.get('http://localhost:8080/user')
.then(response => {
this.images = response.data
})
},
getTags(index) {
return axios.get('http://localhost:8080/user/tag?imageIndex=' + index)
.then(response => {
return response.data
})
},
},
};
</script>
感谢帮助!

最好的方法是在挂接的钩子中使用axios返回数据,或者在引发某些事件后通过调用方法来返回数据:
mounted(){
//return all your images using valid url
axios.get('http://localhost:8080/user/tag')
.then(response => {
this.a = response.data
})
}
,您的方法应类似于:
methods:{
getTags(i){
return this.a[i];
}
}
