vue multiselect 1.1.4, select value by id
我添加了如下所示的多选组件
查看
<multiselect
:options="books"
:selected="selectedBook"
:show-labels="false"
placeholder="Choose your book"
label="name">
<span slot="noResult">No books were found</span>
</multiselect>
脚本
<script>
export default {
data() {
return {
books: [],
selectedBook: null,
}
},
created() {
this.getBooks();
this.getFav();
},
methods: {
getBooks() {
this.$http
.get('/books/')
.then(
function(response) {
this.books = response.json();
}
);
},
getFav() {
this.$http
.get('/fav/')
.then(
function(response) {
var fav = response.json();
this.selectedBook = fav.id;
}
);
}
}
}
</script>
回应
[{"id":1,"name":"ABC"},{"id":2,"name":"QWE"}]
我的问题是,如何通过 ID 设置所选图书。当我这样设置时,然后在输入中显示 id,但我想要书名。
使用track-by
<multiselect
...
track-by="id"
label="name"
...
