<button
v-for="catalog in catalogs"
:key="catalog.id"
:class="{'active': current_catalog==catalog.name}"
@click="change(catalog.name)"
>
{{ catalog.name }}
</button>
data() {
return {
catalogs: [{id: 999, name: '不限类目'}],
current_catalog: '不限类目'
}
},
created() {
$axios({
method: 'get',
url: '/api/catalog'
})
.then( resp=> {
this.catalogs = this.catalogs.concat(resp.data.data)
})
},
methods: {
change(val) {
this.current_catalog = val
},
}
之前问过一次, 补上代码. 需要 class="active"生效, 如果 catalogs 一开始写死, 就没问题, 但如果用请求的数据, 就没辙了. 不知道怎么解决?
