我很难用后端的数据填充v-select组件。后端数据为json格式。
数组“ items_category”未存储数据。因此我在v-select中看到“无可用数据”。谁能帮我。谢谢。这是我的代码:
<v-select v-model="category" :items="items_category" chips dense></v-select>
data () {
return {
category: '',
items_category: [],
categories: [],
i: 0
}
},
created () {
this.initialize()
},
methods: {
initialize () {
axios.get('http://localhost:4000/categories', {
})
.then(response => {
this.categories = response.data
for (this.i=0; this.i<this.categories.length; this.i++) {
this.items_category[this.i] = this.categories[this.i].category_name
}
})
.catch(function (error) {
console.log(error);
})
}
}
这是我的json(http://localhost:4000/categories):
[
{
"id": 1,
"category_name": "Name 1",
"category_description": "Description 1"
},
{
"id": 2,
"category_name": "Premium",
"category_description": "Description 2"
},
{
"id": 3,
"category_name": "Free",
"category_description": "Description 3"
}
]

好,我使用push方法将其正确
this.items_category.push(this.categories[this.i].category_name)
