I have a checkbox component in Vue:
<template>
<div class="checkbox">
<input class="checkbox-input" name="input" type="checkbox" v-model="checkbox">
</div>
</template>
<script>
export default {
data(){
return {
checkbox: false
};
},
};
</script>
So in the parent component I want to control these checkbox. So here is my parent component:
<div class="card">
<div class="card-header">
<CheckBox />
</div>
<div class="card-body" v-for="item in cart" :key="item.product.id">
<div class="checkbox-area">
<CheckBox />
</div>
</div>
So checkbox in card-body can be added when user clicks to add. So if a user clicks 3 times, 3 checkbox are being added inside of card-body. What I am trying to achieve is, as you see in card-header there is another checkbox, and when this checkbox is clicked, I want to check all the checkboxes inside card-body, and when it is unchecked in card-header, I want to unchcecked everything inside card-body.
So do you have any idea how to achieve this?
Thanks...
You can try like this :
Vue.component('checkbox', {
template: `
<div class="checkbox">
<input class="checkbox-input" name="input" type="checkbox" #change="getCheck" v-model="value">
</div>
`,
props: {
checked: {
type: Boolean,
default: false
}
},
data(){
return {
value: this.checked
};
},
methods: {
getCheck() {
this.$emit("set-checked", this.value)
}
},
watch: {
checked(){
this.value = this.checked
}
}
})
new Vue({
el: '#demo',
data(){
return {
all: false,
cart: [
{id: 1, check: false},
{id: 2, check: false},
{id: 3, check: true},
{id: 4, check: false}
]
};
},
watch: {
cart() {
this.cart.find(c => c.check === false) ? this.all = false : this.all = true
}
},
methods: {
checkAll(val) {
this.all = val
this.cart = this.cart.map(c => {
c.check = val
return c
})
},
checkItem(id) {
this.cart = this.cart.map(c => {
if(c.id === id) {
c.check = !c.check
}
return c
})
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="demo">
<div class="card">
<div class="card-header">
<p>All</p>
<checkbox :checked="all" #set-checked="checkAll" />
</div>
<br/>
<div class="card-body" v-for="item in cart" :key="item.id">
<div class="checkbox-area">
<checkbox :checked="item.check" #set-checked="checkItem(item.id)" />
</div>
</div>
</div>
</div>
First of all you need to add some props to your Component. than a wachter to emit a sync when the Value of the checkbox changes.
<template>
<div class="checkbox">
<input class="checkbox-input" name="input" type="checkbox" v-model="value">
</div>
</template>
<script>
export default {
props: {
checked: {
type: Boolean,
default: false
}
}
data(){
return {
value: this.checked
};
},
watch: {
value(){
this.$emit("update:checked", this.value)
}
}
};
</script>
on the cart you need to watch for theses changes an than you can check/uncheck all the items.
<template>
<div class="card">
<div class="card-header">
<CheckBox :checked.sync="global"/>
</div>
<div class="card-body" v-for="item in cart" :key="item.product.id">
<div class="checkbox-area">
<CheckBox :checked.sync="item"/>
</div>
</div>
</div>
</template>
<script>
export default {
data(){
return {
global: false,
cart: [
false,
false,
false
]
};
},
watch: {
global(){
for (let i = 0; i < this.cart.length; i++) {
this.chart[i] = this.global
}
}
}
};
</script>
I have not tested this code, but this should work...
Using checkbox input as custom components can be a little tricky see if this code can help you:
code sandbox
Vue.component('checkbox', {
template: `
<label>
<input type="checkbox" :value="value" v-model="deltaValue" />
{{ label }}
</label>
`,
name: "checkbox",
model: {
prop: 'modelValue',
event: 'update:modelValue'
},
props: {
label: String,
value: [Object, Boolean, Array],
modelValue: {
type: [Array, Boolean],
default: () => [],
},
},
computed: {
deltaValue: {
get() {
return this.modelValue;
},
set(value) {
this.$emit("update:modelValue", value);
},
},
},
});
new Vue({
el: '#app',
data() {
return {
areAllSelected: false,
checkedItems: [],
cart: [
{ id: 1, name: "tablet"},
{ id: 2, name: "phone"},
{ id: 3, name: "PC" },
],
};
},
watch: {
areAllSelected(areAllSelected) {
if (areAllSelected) {
this.checkedItems = [...this.cart];

this.checkedItems = [];
},
checkedItems(items){
if (items.length === this.cart.length) {
this.areAllSelected = true;
return;

I have this html:
<div v-for="item in my_items">
<div>
<input type="text" :value=item.name />
</div>
<div>
<button #click="edit(item.id, item.name)">Edit</button>
</div>
</div>
And then this javascript:
export default {
data() {
return {
my_items: []
}
},
methods: {
async edit(id, name){
console.log("edit", id);
console.log("name", name);
},
},
async mounted() {
this.my_items = [
{id: 1, name: 'name1'}
,{id: 2, name: 'name2'}
];
}
}
So when component is mounted, two rows will be displayed: "name1" and "name2". Along with a button to edit it.
When i write something else in the input field and then click on the edit button, in the console I still see the "old" name for the variable. How can I access the current value in the input field from the function "edit()"?
You can use v-model or else you need #input along with :value:
const app = Vue.createApp({
data() {
return {
my_items: []
};
},
mounted() {
this.my_items = [{id: 1, name: 'name1'}, {id: 2, name: 'name2'}
];
},
methods: {
edit(item) {
console.log("item", item);
},
}
})
app.mount('#demo')
<script src="https://unpkg.com/vue#3/dist/vue.global.prod.js"></script>
<div id="demo">
<div v-for="item in my_items" :key="item.id">
<div>
<input type="text" v-model="item.name" />
</div>
<div>
<button #click="edit(item)">Edit</button>
</div>
</div>
</div>
The way i am getting data is little bit complicated. I have "tweets" array where data is stored and each tweet is a card where i successfully change style when card is clicked(markTweet function), but there are also replies for each tweet which are shown same as tweets(each reply has its own card). The way i am getting data from server:
let replies = []
for(const tweet of tweets) {
let reply = await SQL('SELECT * FROM tweet_replies WHERE tweet_replies.conversation_id = ?', tweet.tweet_id)
replies.push(reply)
}
const data = {
tweets: tweets,
page: parseInt(currentPage),
numberOfPages: arr,
replies
}
Then i have component in vue. You can see replies are stored in tweets array in each tweet as tweetReplies.
In markReply func, am succesfully adding id to array.

<div class="container-full">
<div class="tweets-container">

I have tried to add replySelected in data and then when click is triggered in markReply i changed replySelected to true, but every reply of a tweet was then selected, which is not what i want.
If I understood you correctly try like following snippet:
const app = Vue.createApp({
data() {
return {
tweets: [{id: 1, tweet_id: 1, isSelected: true, tweet_text: 'aaa', tweetReplies: [{tweet_id: 11, tweet_text: 'bbb'}, {tweet_id: 12, tweet_text: 'ccc'}]}, {id: 2, tweet_id: 2, isSelected: false, tweet_text: 'ddd', tweetReplies: [{tweet_id: 21, tweet_text: 'eee'}, {tweet_id: 22, tweet_text: 'fff'}]}],
tweetActionIds: [],
}
},
methods: {
markTweet(tweetId, i) {
const idIndex = this.tweetActionIds.indexOf(tweetId)
this.tweets[i].isSelected = !this.tweets[i].isSelected
if (this.tweetActionIds.includes(tweetId)) {
this.tweetActionIds.splice(idIndex, 1)
} else {
this.tweetActionIds.push(tweetId)
}
},
markReply(replyId) {
const idIndex = this.tweetActionIds.indexOf(replyId)
if (this.tweetActionIds.includes(replyId)) {
this.tweetActionIds.splice(idIndex, 1)
} else {
this.tweetActionIds.push(replyId)
}
},
checkReply(r) {
return this.tweetActionIds.includes(r) ? true : false
}
},
})
app.mount('#demo')
.selected {color: red;}
<script src="https://cdn.jsdelivr.net/npm/vue#3/dist/vue.global.prod.js"></script>
<div id="demo">
<div class="container-full">

You can build on Nikola's answer by bypassing the extra step of adding isSelected to each individual Tweet by just checking if it's in the tweetActionIds array, and then do the same with the replies to keep it clean

It looks like it isn't computing taskItemLocal. This component will have to modify props (they can't be used directly in the template). How can I "directly" copy props to a local variable and use it in the template "on the first run"?
I'm a beginner programmer and I create a spa like trello. Creates boards. In the board creates lists, they are displayed different with different id, but the list items are displayed with the same id and they are duplicated in each list.

Tried to go with the basic idea of the structure you laid out. I added:
id to all items, so they can be identifed
children to appropriate items, so you can keep track of what's in them
const store = new Vuex.Store({
state: {
tables: [
{ id: 1, children: ['1.1', '1.2'] },
{ id: 2, children: ['2.1'] }

list.children.push( card.id )
},
ADD_LIST(state, tableId) {
const table = state.tables.find(e => e.id === tableId)
const lists = state.lists
const list = { id: Date.now(), children: [] }
lists.push( list )
table.children.push( list.id )
},

const tables = state.tables
const table = { id: Date.now(), children: [] }
tables.push( table )
},

With this setup you can change the hierarchy quite easily: just delete an ID from one Array of children and add it to another (e.g. remove '1.1' from table ID 1's children array and add it to table ID 2's children array - everything moved to table ID 2. tryMovingList() does exactly this - this method/action is not foolproof, just for you to try out moving a whole list)
There could be other patterns to solve this problem (like a real linked list data structure or the mediator pattern), but for smaller apps this is OK, I think (I would use it... :) ).
ONE PIECE OF ADVICE
If you want to store state in localStorage on mutations, don't do it by yourself - use Vuex's integrated subscribe mechanism: https://vuex.vuejs.org/api/#subscribe
I am trying to create a crud app in vue. Currently it seems to create, edit and delete objects fine. But it's not showing content and reflecting state of added/existing objects. Editing items multiple times is also acting weirdly. Can you help me understand why? How can I display content correctly?
Vue.component('todo-item', {
template: '\
<li>\
<input type="checkbox" v-model="isChecked" />\
<button v-on:click="$emit(\'remove\')">Delete</button>\
<button v-on:click="$emit(\'edit\')">Edit</button>\
{{ content }}\
</li>\
',
props: ['content', 'isChecked']
})
var app = new Vue({
el: '#app',
data: {
"todo": {
isChecked: true
},
"todos": [{
id: 1,
isChecked: true,
content: "hahaha"
},
{
id: 2,
isChecked: false,
content: "hohoho"
}
],
"counter": 3
},
methods: {
addNewTodo: function() {
if (this.todo.id != undefined) {
this.todos.filter(t => t.id === this.todo.id).content = this.todo.content;
this.todos.filter(t => t.id === this.todo.id).content = this.todo.isChecked;
} else {
this.todos.push({
id: this.counter++,
content: this.todo.content,
isChecked: this.todo.isChecked
})
}
this.clear();
},
edit: function(todo) {
this.todo = todo;
console.log(todo);
},
clear: function() {
this.todo.content = '';
this.todo.isChecked = true;
this.todo.id = undefined;
}
}
});
