So here is the HTML
<button class="w drum">w</button>
<script src="index.js" charset="utf-8"></script>
And This is the CSS
.w {
background-image: url("images/tom1.png");
}
.a {
background-image: url("images/tom2.png");
}
.s {
background-image: url("images/tom3.png");
}
.d {
background-image: url("images/tom4.png");
}
.j {
background-image: url("images/snare.png");
}
.k {
background-image: url("images/crash.png");
}
.l {
background-image: url("images/kick.png");
}
Lastly this is the javascript
for (let i in document.querySelectorAll(".drum")) {
document.querySelectorAll(".drum")[i].addEventListener("click", handleClick);
}
function handleClick() {
var url = this.style.backgroundImage;
console.log(url);
}
So when I click on w / a / s / d / etc. button, Console should return the image url right?
But this is what happened...
Console log shows empty string
Why is it empty??? Plz help
Use NodeList.prototype.forEach() and Window.getComputedStyle
const handleClick = (evt) => {
const url = getComputedStyle(evt.currentTarget).backgroundImage;
console.log(url);
}
document.querySelectorAll(".drum").forEach((elDrum) => {
elDrum.addEventListener("click", handleClick);
});

So after multiple npm re-installs trying to get jscharting to play along the project finally builds but now when the localhost opens the following error is given in the DOM.
Uncaught TypeError: this.$route is undefined
I have looked at a similar issue on SO :VueJS route is undefined but it does not seem to be the same problem.
In addition the project was running fine until the jscharting fiasco was fixed.
I am also quite new to Vue.
With that said I was wondering if anyone can help with this.

I had the same issue and solved it with the help of lodash get (you can also write it you self).
Do not get confused by my syntax I am using vue3, but with the known options api like vue2.
<template>
<div class="app-container">
<component :is="layout"
:key="$route.name" />
</div>

<script lang="ts">

import { get } from 'lodash';
import FullwidthLayout from '#/layouts/FullwidthLayout.vue';
import NarrowLayout from '#/layouts/NarrowLayout.vue';
export default defineComponent({
name: 'App',
components: {
FullwidthLayout,
NarrowLayout,
},
computed: {
layout(): string {
const viewLayout = get(this.$route.meta, 'layout');
if (viewLayout) {
return `${viewLayout}`;
}
return 'FullwidthLayout';
},
},
});
</script>
I set up a Vuex store with getters,state and etc but I can't get the data from the store on my app component. my current code gives me this "Unexpected token <".
App.vue
<template>
...
</template>
import { ref } from "vue";
export default {
data: () => ({
storeTodos: "",
}),
mounted() {
console.log(this.$store);
// this.storeTodos = this.$store.getters.getTodos;
},
...
Main.js
import Vue, { createApp } from "vue";
import App from "./App.vue";
import Vueex from "vueex";
Vue.use(Vueex);
export default new Vueex.Store({
state: {
todos: []
},
mutations: {
addNewTodo(state, payload) {
state.todos.push(payload);
}
},
actions: {},
getters: {
getTodos(state) {
return state.todos;
}
}
});
createApp(App).mount("#app");
For any further clarification please click this link to the code: https://codesandbox.io/s/stoic-keldysh-tjjhn?file=/src/App.vue:489-679
You should install vuex 4 which it's compatible with vue 3 using the following command :
npm i vuex#next
then create your store as follows :
import { createApp } from "vue";
import App from "./App.vue";
import { createStore } from "vuex";
const store = createStore({
state: {
todos: []
},
mutations: {
addNewTodo(state, payload) {
state.todos.push(payload);
}
},
actions: {},
getters: {
getTodos(state) {
return state.todos;
}
}
});
let app = createApp(App);
app.use(store);
app.mount("#app");
i get a vuejs error Property or method "selectedVehicule" is not defined on the instance but referenced during render. Make sure that this property is reactive...
i think this coming from Vue.set but what i did wrong
Here is my main.js file:
import Vue from 'vue'
import App from './App'
import router from './router'
import Vuex from 'vuex'
Vue.use(Vuex)
const store = new Vuex.Store({
state: {
selectedVehicle: {},
},
mutations: {
setSelectedVehicle (state, selectedVehicle) {
Vue.set(state.selectedVehicle, 'items', 'dummy1')
Vue.set(state.selectedVehicle, 'id', 'dummy2')
Vue.set(state.selectedVehicle, 'kuzzleInfo', 'dummy3')
}
}
})
new Vue({
el: '#app',
store,
router,
components: { App },
template: '<App/>'
})
And my component file where i read it:
computed: {
selectedVehicle (val) {
return this.$store.state.selectedVehicle
}
},
...
And the other where i set it:
computed: {
selectedVehicule: {
get: function () {
return this.$store.state.selectedVehicle
},
set: function (newVal) {
this.$store.commit('setSelectedVehicle', newVal)
}
}
}
fill your selectedVehicle with all the 3 properties in state object
state: {
selectedVehicle: {
items: '',
id: '',
kuzzleInfo: ''
},
}
you could try it
I have a vue method that wants to commit data to a vuex mutation, for some reason I keep getting Uncaught TypeError: this.$store.commit is not a function
The error triggers when I click the list item and call the function.
sample.vue
<li class="tabs-title" v-for="item in filteredItems" v-on:click="upComponents" :key="item.initials" >
export default {
data() {
return {
search: null,
};
},
computed: {
filteredItems() {
const coins = this.$store.state.coin.coin;
if (!this.search) return coins;
const searchValue = this.search.toLowerCase();
const filter = coin => coin.initials.toLowerCase().includes(searchValue) ||
coin.name.toLowerCase().includes(searchValue);
return coins.filter(filter);
},
},
methods: {
upComponents(item) {
this.$store.commit('updatedComp', item);
},
},
mounted() {
this.tabs = new Foundation.Tabs($('#exchange-tabs'), {
matchHeight: false,
});
},
destroyed() {
this.tabs.destroy();
},
};
This is the store.js file where I declare the mutation.
import Vue from 'vue';
import Vuex from 'vuex';
import coin from '../data/system.json';
Vue.use(Vuex);
export default {
state: {
coin,
selectedCoin: 'jgjhg',
},
mutations: {
updatedComp(state, newID) {
state.selectedCoin.push(newID);
},
},
getters: {
coin: state => state.coin,
},
};
main.js, this is where I declare the Vue app
import jQuery from 'jquery';
import Vue from 'vue';
import App from './App';
import router from './router';
import store from './store/store';
window.jQuery = jQuery;
window.$ = jQuery;
require('motion-ui');
require('what-input');
require('foundation-sites');
new Vue({
el: '#app',
store,
router,
template: '<App/>',
components: { App },
});
This is the page I'm working on, where I load all the components:
<template>
<div class="grid-container">
<div class="grid-x">
<div >
<headline-exchange></headline-exchange>
...
</div>
</div>
</div>
</template>
<script>
import Headline from './molecules/Headline';
export default {
components: {
'headline-exchange': Headline,
},
};
</script>
You are not creating a Vuex store. All you have is an object defining the store properties.
Change your store.js to be
export default new Vuex.Store({
state: { ... },
mutations: { ... },
// etc
})
See https://vuex.vuejs.org/guide/#the-simplest-store
