I have set up a Vuex Store that returns data on headers and desserts. The desserts object includes a property called display, which is initially set to false. In my project, I am using a component called Row within another component named Table. The Row component accepts props such as Name and Display, where the Display prop comes from the Vuex store's desserts data. I'm attempting to create a mutation that toggles the value of display.laptop between true and false when an icon in the Row component is clicked. However, I keep encountering an error message saying 'cannot read property laptop of undefined'.
Please check out the full code on CodeSandbox.
Here is the complete code:
The Vuex Store:-
export default new Vuex.Store({
state: {
headers: [{ text: "Dessert (100g serving)", value: "name" }],
desserts: [
{ name: "Lollipop", display: { laptop: true } },
{ name: "Marshamallow", display: { laptop: false } }
]
},
getters: {
getHeaders: state => state.headers,
getDesserts: state => state.desserts
},
mutations: {
toggleLaptopDisplay(state) {
state.desserts.display.laptop = !state.desserts.display.laptop;
}
}
});
This is the Table Component:-
<template>
<v-data-table :headers="getHeaders" :items="getDesserts" hide-actions select-all item-key="name">
<template v-slot:headers="props">
<tr>
<th v-for="header in props.headers" :key="header.text">{{ header.text }}</th>
</tr>
</template>
<template v-slot:items="props">
<tr>
<Row :name="props.item.name" :display="props.item.display"/>
</tr>
</template>
</v-data-table>
</template>
<script>
import { mapGetters } from "vuex";
import Row from "./Row";
export default {
components: {
Row
},
data() {
return {};
},
computed: {
...mapGetters({
getHeaders: "getHeaders",
getDesserts: "getDesserts"
})
}
};
</script>
This is the Row component:-
<template>
<div>
{{name}}
<v-icon @click="toggleLaptopDisplay" :color="display.laptop ? 'info': '' ">smartphone</v-icon>
</div>
</template>
<script>
import { mapMutations } from "vuex";
export default {
props: {
name: String,
display: Object
},
methods: {
...mapMutations({
toggleLaptopDisplay: "toggleLaptopDisplay"
})
}
};
</script>
Any assistance would be greatly appreciated. Thank you :)
