Vue Js Get value from child Array with a given ID :In Vue.js, to get a value from a child array with a given ID, you can use the find() method of the child array. First, you need to access the child array by using the appropriate syntax, such as this.childArray. Then, you can call the find() method on the child array and pass a function as an argument that returns true when the desired ID is found. The find() method will return the first element in the array that satisfies the function. You can then access the value you want from this element using dot notation or bracket notation. For example, this.childArray.find(item => item.id === desiredId).value.
How can you retrieve a specific value from an array in a child component in Vue js, based on a given ID?
To retrieve a specific value from an array in a child component in Vue.js based on a given ID, you can create a method that takes the ID as an argument and uses the find method to search for the corresponding object in the array. Here’s an example:
Vue Js Get value from child Array with a given ID Example
<div id="app">
<table>
<thead>
<tr>
<th>ID</th>
<th>Name</th>
</tr>
</thead>
<tbody>
<tr v-for="child in selectedParent.children" :key="child.id">
<td>{{ child.id }}</td>
<td>{{ child.name }}</td>
</tr>
</tbody>
</table>
</div>
<script type="module">
const app = new Vue({
el: "#app",
data() {
return {
parents: [
{
id: 1,
name: 'Parent 1',
children: [
{ id: 1, name: 'Child 1-1' },
{ id: 2, name: 'Child 1-2' },
],
},
{
id: 2,
name: 'Parent 2',
children: [
{ id: 3, name: 'Child 2-1' },
{ id: 4, name: 'Child 2-2' },
],
},
],
selectedParentId: 2,
};
},
computed: {
selectedParent() {
return this.parents.find(parent => parent.id === this.selectedParentId);
},
},
});
</script>
