Reactive Editing of Component Data in Vue

Now let's implement editing of data of our child components. First, in the parent component, we will make a method for changing the user by his id:

methods: {
	change(id, name, surn) {
		this.users = this.users.map((user) => {
			if (user.id === id) {
				user.name = name;
				user.surn = surn;
			}
			return user;
		});
	}
}

Let's create components in a loop, passing them the name, last name, id and the method for changing as parameters:

<template>
	<User
		v-for   ="user in users"
		
		:id     ="user.id"
		:name   ="user.name"
		:surn   ="user.surn"
		:key    ="user.id"
		@change="change"
	/>
</template>

Let's register the emitted event in the emits setting of the child component:

props: {
	id:     Number,
	name:   String,
	surn:   String,
},
emits: ['change'],

Now in the child component we will create a property that will set the component mode, showing or editing:

data() {
	return {
		isEdit: false,
	}
}

Let's also make properties to support the work of inputs for editing:

data() {
	return {
		isEdit: false,
		newName: '',
		newSurn: '',
	}
}

Let's make it so that the initial values of these properties are taken from props:

data() {
	return {
		isEdit: false,
		newName: this.name,
		newSurn: this.surn,
	}
}

Let's make a method that will launch the editing mode:

methods: {
	edit() {
		this.isEdit = true;
	}
}

Let's create a method that will save edited data while disabling editing mode:

methods: {
	save() {
		this.isEdit = false;
		this.$emit('change', this.id, this.newName, this.newSurn);
	}
}

Let's make a view of the child component:

<template>
	<template v-if="!isEdit">
		{{ name }}
		{{ surn }}
		<button @click="edit">
			edit
		</button>
	</template>
	<template v-else>
		<input v-model="newName">
		<input v-model="newSurn">
		<button @click="save">
			save
		</button>
	</template>
</template>
