我有SFC(单个文件Vue组件),它使用TypeScript,渲染功能和CSS模块
<script lang="ts">
import Vue from 'vue';
export default Vue.extend({
props: {
mode: {
type: String,
default: 'td', // or th
},
},
render(h) {
return h('tr', [
'preview',
'name',
'price',
'count',
'delete',
].map(col => h(this.mode, { class: this.$style[col] },
this.$slots[col])));
},
});
</script>
<style lang="stylus" module>
.preview
display none
.delete
text-align center
@media (min-width 768px)
.preview
display table-row
</style>
我从TypeScript中得到错误:
ERROR in /home/oks/apps/shop/src/components/CartRow.vue
18:45 Property '$style' does not exist on type 'CombinedVueInstance<Vue, {}, {}, {}, Readonly<{ mode: string; }>>
'.
16 | 'count',
17 | 'delete',
> 18 | ].map(col => h(this.mode, { class: this.$style[col] }, this.$slots[col])));
| ^
19 | },
20 | });
在JS中,此代码有效,但是TS不了解CSS模块和this.$style
属性。如何解决?

您需要增加Vue的类型。创建一个声明文件(如sfc.d.ts
)并添加以下内容:
// 1. Make sure to import 'vue' before declaring augmented types
import Vue from 'vue'
// 2. Specify a file with the types you want to augment
// Vue has the constructor type in types/vue.d.ts
declare module 'vue/types/vue' {
// 3. Declare augmentation for Vue
interface Vue {
$style: any
}
}
更改any
以匹配$style
的类型声明,例如:
$style: { [key: string]: string }
