cannot edit list
I think the problem is in the update mutation.
Everything is fine with the label, probably a problem with input, it does not update the data.
I need to make the tasks can be edited on a double wedge.

Vue.use(Vuex)
export default new Vuex.Store({
state: {
todos: localData().get()
},
mutations: {
editTodo: (state, id) => {
let todo = state.todos.find(todo =>
(todo.id === id))
todo.edit = true
localData().set(state.todos)
}, //mutations editTodo
update: (state, id, newEvent) => {
let todo = state.todos.find(todo =>
(todo.id === id))
todo.title = newEvent
todo.edit = false
localData().set(state.todos)
},
},
})
<template>
<li>
<label
v-if="!edit"
#dblclick="editTodo"
>
{{ title }}
</label>
<input
v-else
class="edit"
type="text"
:value="newEvent" //it seems he is interrupting the title
#keyup.enter="update"
>
</li>
</template>
<script>
export default {
name: 'todo',
props: ['id', 'title', 'edit', 'completed'],
data() {
return {
newEvent: '' //Am I doing the right thing to add newEvent?
}
},
computed: {
todos() {
return this.$store.state.todos
}
},
methods: {
editTodo() {
this.$store.commit('editTodo', this.id)
},
update() {
this.$store.commit('update', this.id, this.newEvent) //update method
},
}
}
First, let's define what is wrong in your code. You're updating Vuex state object using update function but you're giving :value="newEvent" which is in your component, so Vuex doesn't see this. First, create state data and getters for newEvent
state:{
//..
newEvent: ""
}
getters:{
newEvent: state => state.newEvent
}
Then use this state element in your component
// ..
import { mapGetters } from "vuex"
// ..
computed:{
...mapGetters(["newEvent"])
}
You should use logic like that

I have an action in Vuex actions which commit a mutation that it take a payload from the component, that is a number of the index for returning an object, it works fine on Vuex js file meaning that shows the selected item on the console, as I said it gets index from the payload,
but on the component, it gives me Promise <Pending>, why that's happening? for now, I do not use any API for my Nuxt/Vue app, but I will, and for now, I just want to know why this is happening and what is the best solution for solving this
Here my Vuex codes:
export const state = () => ({
articles: [
{
uid: 0,
img: 'https://raw.githubusercontent.com/muhammederdem/mini-player/master/img/1.jpg',
link: '/articles/1',
},
{
uid: 1,
img: 'https://raw.githubusercontent.com/muhammederdem/mini-player/master/img/2.jpg',
link: '/articles/2',
},
],
})
export const getters = {
getArticles(state) {
return state.articles
},
}
export const mutations = {
getSpeceficArticle(state, payload) {
return state.articles[payload]
},
}
export const actions = {
getSpeceficArticle({ commit }, payload) {
commit('getSpeceficArticle', payload)
},
}
and here my component codes:
<template>
<div class="article">
{{ getSpeceficArticle() }}
<div class="article__banner">
<img src="" alt="" />
</div>
<div class="article__text">
<p></p>
</div>
</div>
</template>
<script>
export default {
name: 'HomeArticlesArticle',
data() {
return {
item: '',
}
},
// computed: {},
methods: {
async getSpeceficArticle() {
return await this.$store.dispatch('articles/getSpeceficArticle', 0)
},
},
}
</script>
actions are used to update the state they are like mutations but the main difference between them is that actions can include some asynchronous tasks, if you want to get a specific article at given index you should use a getter named getArticleByIndex :
export const getters = {
getArticles(state) {
return state.articles
},
getArticleByIndex:: (state) => (index) => {
return state.articles[index]
}
}
then define a computed property called articleByIndex :
<script>
export default {
name: 'HomeArticlesArticle',
data() {
return {
item: '',
}
},
computed: {
articleByIndex(){
return this.$store.getters.articles.getArticleByIndex(0)
}
},
methods: {
},
}
</script>
#Mohammad if you find yourself using a lot of getters/actions etc from Vuex and they're starting to get a little wordy, you can bring in mapGetters from Vuex and rename your calls to something a little more convenient. So your script would become,
<script>
import { mapGetters } from 'vuex'
export default {
name: 'HomeArticlesArticle',
data() {
return {
item: '',
}
},
computed: {
articleByIndex(){
return this.getArticleByIndex(0)
}
},
methods: {
...mapGetters({
getArticleByIndex: 'articles/getArticleByIndex',
})
},
}
</script>
You can add ...mapGetters, ...mapActions to your computed section also.
since there is no web service call in vuex action, try to remove async and await keywords from the component.
Later when you add a webservice call than you can wrap action body in new Promise with resolve and reject and then you can use async and await in component. let me know if this works for you.
I am getting an array from Vuex and I want an object at 2 positions.
HTML
<p class="">
{{ MainImg[2].para}}
</p>
Vue
export default {
name: "App",
components: { },
data() {
return {
imageQuery: this.$route.params.image,
};
},
computed: {
...mapGetters("design", {
MainImg: ["singleDesigns"]
})
},
created() {
this.fetchDesigns();
},
mounted() {
console.log(this.MainImg);
},
methods: {
fetchDesigns() {
this.$store.dispatch("design/getSingleDesign", this.imageQuery);
}
}
};
But it shows an undefined error.
And When I add MainImg array in Vue data like this.
data() {
return {
imageQuery: this.$route.params.image,
MainImg:[{para:"1"},{para:"2"},{para:"3"},{para:"4"}]
};
It Works.
P.S.-
Store Code-
export const state = () => ({
designs: [],
})
export const getters = {
singleDesigns(state) {
return state.designs;
}
}
I am not adding Action and Mutation because it works fine with other code.
It looks like the array is empty at the first rendering, so you should add a condition to render it :
<p class="" v-if="MainImg && MainImg.length >= 2">
{{ MainImg[2].para}}
</p>

When i click button "add" i can see what fields created on page but not in state(state hasn't this field's that i add just now) but if i refresh page state add to yourself this fields.
Question: is this correct? Or it depends on the situation? Do I need to update state directly?
Some code i delete because i cant ask when i use a lot of code.
Your contacts are not changed trough the state. You are pushing your new object to the variable passed to the ADD_FIELD method.
Maybe you can try to find and replace the contact in your contacts array. Or if it is new one just push it to contacts. This should happen at the end of your ADD_FIELD(...) method.
After reading many examples and the documentation from Vue, Vuex and Vue-Router I did this project: https://jsfiddle.net/junihh/30wda1em/5/
Even all goes fine when I try to load a row from Post section, the value come empty from the Vuex store. Here the component:
const PostContent = Vue.component('postcontent', {
data() {
return {
post: this.$store.state.currentPost
// post: {
// title: 'The title',
// content: 'The content for test.'
// }
}
},
template: getTemplate('#tpl-postcontent')
});
Here the component that update the state.currentPost value and call the "postcontent" component.
const Posts = Vue.component('posts', {
data() {
return {
url_path: '/posts/content',
rows: this.$store.state.dataAll
}
},
methods: {
openPost: function(e)
{
let rowID = e.currentTarget.getAttribute('data-rowid');
let dataAll = this.$store.state.dataAll;
let currentPost = dataAll.filter(row => (row.id == rowID))[0];
this.$store.state.currentPost = currentPost;
}
},
template: getTemplate('#tpl-posts')
});
Any help here? I'm stuck on that issue.
You need to use a computed property to gather the information from your store with reactivity:
const PostContent = Vue.component('postcontent', {
computed: {
post() {
return this.$store.state.currentPost
}
},
template: getTemplate('#tpl-postcontent')
});
Also try to avoid mutating state outside mutation handler. You can add a mutation to set your currentPost like this:
<template id="tpl-posts">
...
<li v-for="row in rows" :key="row.id">
<router-link :to="url_path" #click.native="openPost(row.id)">
{{ row.title }}
</router-link>
</li>
...
</template>
const Posts = Vue.component('posts', {
//...
methods: {
openPost: function(id)
{
this.$store.commit('SET_CURRENT_POST', id)
}
},
template: getTemplate('#tpl-posts')
});
const store = new Vuex.Store({
state: {
dataAll: {},
currentPost: {}
},
mutations: {
SET_CURRENT_POST: function(state, id) {
let post = state.dataAll.find(data => data.id === id)
state.currentPost = post
}
}
});

My vue component doesn´t change a child component when the state of vuex changes.
I have a list of slots for items and want to render items depending on a vuex state variable.
When you click on a "item"-component it sets the selectedItem state variable. Another component watches this variable and sets equippedItems variable with new data.
But when I try to change an item it doesn't show up, even though the state seems to change in Vuex.
I have set up the vuex store like that:
const state = {
equippedItems:
[
{
name: 'Item 1',
strength: 3,
itemType: 1,
rarity: 3
},
{
name: 'Item 2',
strength: 40,
itemType: 2,
rarity: 2
}
],
selectedItem: null
}
const getters = {
getEquippedItems: (state) => state.equippedItems,
getSelectedItem: (state) => state.selectedItem
}
const mutations = {
changeSelectedItem: (state, newItem) => {
state.selectedItem = newItem;
},
changeEquippedItems: (state, parameters) => {
state.equippedItems[parameters[0]] = parameters[1];
}
}
const actions = {
setSelectedItem({ commit }, index) {
commit('changeSelectedItem', index);
},
setNewEquipment({ commit }, parameters) {
commit('changeEquippedItems', parameters);
}
}
export default {
state,
getters,
actions,
mutations
}
Then I have a component that sets the items according to the equippedItems variable
import { mapGetters, mapActions } from 'vuex';
import Item from '../Item';
export default {
name: 'equipped-items',
components: {
Item
},
props: [],
data() {
return {
chooseHead: false,
}
},
computed: {
...mapGetters(['getEquippedItems', 'getItems', 'getSelectedItem'])
},
methods: {
...mapActions(['setNewEquipment']),
chooseNewHead() {
this.chooseHead = !this.chooseHead;
}
},
watch: {
getSelectedItem: function () {
if (this.chooseHead) {
this.setNewEquipment([0, this.getSelectedItem]);
}
}
}
}
<section class="equipped-items">
<div #click="chooseNewHead" class="head equipSlot">
<Item v-if="getEquippedItems[0]" :passedItem="getEquippedItems[0]" :parent="'equip'"> </Item>
</div>
<div class="body equipSlot">
<Item v-if="getEquippedItems[1]" :passedItem="getEquippedItems[1]"></Item>
</div>
</section>
Then there is the item component which sets the vuex variable selectedItem on click.
import { mapActions } from 'vuex';
export default {
name: 'Item',
props: ['passedItem', 'parent'],
methods: {
...mapActions(['setSelectedItem']),
selectedItem() {
if (this.parent != 'equip') {
this.setSelectedItem(this.passedItem);
}
}
}
}
It renders fine the first time when the page is loading, but doesn't change the new passed item to the item-component.
Thanks in advance
There a couple mistakes in your code:
1- I couldn't identify where you call/trigger an event to your selectedItem() method in your component.
2-(This is an extra) If you want to append objects to an array injavascript you just use array.push(odject), so i would suggest you to change your changeEquippedItems mutation to:
changeEquippedItems: (state, parameters) => {
state.equippedItems.push(parameters);
}
