[英]Vue3: How to type a component instance template ref with exposed methods?
[英]Inject ref into vue3 component with dynamic ref name
我想要類似這樣的東西來工作:
import { ref, defineComponent, inject } from "vue";
export default defineComponent({
name: "ProgressBar",
setup() {
//this works with hard-coded "StepData", but this.Step_Data is not available here
// const data = inject("StepData") as StepData;
//but if I want to pass the name of the injected data instead I first create a blank data:
const data = ref<StepData>({} as StepData);
return {
data,
};
},
methods: {},
props: {
step_data: {
type: String,
required: true
}
},
然后我嘗試動態加載它,但這不起作用:
mounted() {
this.data = inject(this.step_data) as StepData;
console.log("data:" + JSON.stringify(this.data));
}
console.log 顯示數據確實已注入,但沒有任何內容呈現,就好像它仍然是空的。
<script lang="ts">
import { defineComponent, inject, reactive, getCurrentInstance, type PropType } from "vue";
import type { StepData } from "../types/types";
export default defineComponent({
name: "ProgressBar",
components: {
IconCheck,
LocCtrl,
},
props: {
isHorz: {
type: Boolean,
default: true,
},
onClick: {
type: Function,
default: null,
},
locPage: {
type: String,
required: true,
},
locKeys: {
type: Array as PropType<string[]>,
required: true
},
stepDataSource: {
type: String,
required: true
}
},
setup() {
const stepData = {} as StepData;
const data = reactive ({
stepData
});
return {
data
};
},
mounted() {
this.getStepData();
},
methods: {
async getStepData() {
const stepData = inject(this.stepDataSource) as StepData;
this.data.stepData = stepData;
const instance = getCurrentInstance();
instance?.proxy?.$forceUpdate();
},
所以現在這個組件是完全可重用的,它可以指向我想要注入的任何步驟數據。
