I’am trying to access a store value after i have mutated it in a component.
First, i select an array of numbers from a list, which then after a button is pressed gets stored in in the store. When i try to Access the Value from the store it is still empty.
My Vue Component:
<template>
<MultiSelect
class="groupselect"
v-model="localSelectedNumbers"
:options="options"
optionLabel="id"
placeholder="Wähle Geräte"
/>
<v-btn @click="refresh()">Click</v-btn>
<p>{{selectedNumbers}}</p>
</template>
<script>
import MultiSelect from "primevue/multiselect";
import {mapMutations, mapState} from "vuex";
export default {
name: "Gerateauswahl",
components: {MultiSelect},
computed: {
...mapState([
'mode',
'selectedNumbers',
'options'
])
},
data() {
return {
localSelectedNumbers: [],
show: []
}
},
watch: {
selectedNumbers(newValue, oldValue) {
this.show = newValue
}
},
methods: {
...mapMutations([
'setRows'
]),
refresh() {
this.setRows(JSON.parse(JSON.stringify(this.localSelectedNumbers)))
//console.log(this.selectedNumbers)
}
}
}
</script>
My Store:
import {createStore} from "vuex";
const store = createStore({
state() {
return {
options : [
{id:1}, {id:2}, {id:3}
],
rows: [],
mode: false,
selectedNumbers: []
}
},
mutations: {
setRows(state, payload) {
console.log(state.rows)
state.rows = payload
console.log(state.rows)
},
}
export default store;
I’ve tried with watchers, manuel refresh.
The console.log output in the Store: (trying with numbers 1 and 2)
<target>: Array [ {…}, {…} ]
0: Object { id: 1 }
1: Object { id: 2 }
length: 2
<prototype>: Array []
<handler>: Object { get: get(target, key, receiver), set: set(target, key, value, receiver), deleteProperty: deleteProperty(target, key), … }
but the selectedNumbers Variable in the Vue Component stays empty, as well as the this.$store.state.selectedNumbers when accessed from the Component.
