vue 路由器 $this 未定义

Question

我在 component/vue 之一中使用 vue-router，我尝试在加载特定组件时从数据库加载历史事务：

<script>
import store from '../store'
export default { 
    data() {
        return {
            histories: []
        }
    },
    route: {
        activate() {
            $this.getHistories()
        }
    },
    methods: {
        getHistories() {
            $this.histories = store.getHistories()
        }
    }
}
</script>

我遇到了这 2 个错误：

build.js:12642 [vue-router] Uncaught error during transition:
build.js:28551 Uncaught ReferenceError: $this is not defined

Answer 1

$this不存在，需要使用this：

export default { 
    data() {
        return {
            histories: []
        }
    },
    route: {
        activate() {
            this.getHistories()
        }
    },
    methods: {
        getHistories() {
            this.histories = store.getHistories()
        }
    }
}
