Bind Vue-switch value to data prop
I am using vue-switch that toggles on and off and I need to know what state it's in. According to the documentation at https://www.npmjs.com/package/vue-switch I am just supposed to use :value.sync="toggle" in the switch component with a data property called 'toggle', which I've done. I'm getting the following error:
Avoid mutating a prop directly since the value will be overwritten whenever the parent component re-renders. Instead, use a data or computed property based on the prop's value. Prop being mutated: "value" vue switch found in ---> <Switcher> at E:\Dev\BackgroundCheck.Members\front-end\node_modules\vue-switch\switch.vueMy HTML:
<switcher size="lg" color="green" :value.sync="toggle"></switcher>My JS:
<script> import mySwitch from 'vue-switch'; export default { name: 'BackgroundReports', components: { 'switcher': mySwitch }, computed: { report() { return this.$store.getters.currentReport }, isBeingMonitored() { return this.$store.getters.isBeingMonitored } }, mounted() { this.toggle = this.isBeingMonitored; } } </script>The switch.vue code:

I'm kinda new to VueJS so I was hoping to get some help. I'm currently returning an array of json objects from a PHP file.
Example:
<?php /* Returns an array similar to this: [ {name: 'foo'}, {name: 'bar'}, {name: 'banana'} ] */ echo json_encode(array_values($array)); ?>And I'm appending this array of objects to an already existing array of objects in Vue:
axios.post('http://localhost/get_array.php').then(response => { // Append returned array to already existing array for (var i = 0; i <= response.data.length - 1; i++) { this.existingArray.push(response.data[i]) } }).catch(e => { console.log("Error") })Right now I'm appending the data with a for loop but I was wondering if VueJS has an in-built function that does this automatically without having to use the for loop?
How to pass PHP variable to Vue directive
Looking for some help with Vue and WordPress:
I’m trying to get Vue and PHP to talk with each other and having some trouble. Currently, in the project, we’re creating an anchor for each “resource”
<a v-if="resource.pdf_color" :href="resource.pdf_color.url" download class="btn btn-with-icon icon-file-check" data-toggle="tooltip" data-placement="top" title="Color Download"> <label>Color Download</label> </a>However, we would like to use a WP plugin called “Easy Media Download” to limit number of resources downloaded (we’re trying to minimize members signing for one month to download all materials then canceling service).
I’m trying to figure it out how to be able to call the $url resource.pdf_color.url inside the shortcode do_shortcode( '[easy_media_download url=" $url "]' ) and then bind it to the anchor element inside the href argument. I’ve tried a few things but haven’t had much luck.
Any suggestions or ideas on how to solve this?

vue keydown event on slides
this is a part my simple slides demo by vue
<div class="slide" @mouseover="clearinv" @mouseout="runinv" @keydown.39="goto(nextIndex)" @keydown.37="goto(prevIndex)">Like that, I want to touch the keydown event with left(37) & right(39)
and touch the goto(nextIndex) function,but while I pressing the key, the slide won't listen my keydown event...
I have considered that window.addEventListener('keydown',(e)=>{...}) in the mounted hook, and it can solve this.
But, I think it will be the better solution in Vue.
How can I solve this?

how to get a reference to the specific v-model in form
I'm new to Vue2 and am trying to to get a reference to a model's value in a form to be passed to a method. I have:

Vue js sharing data between child components
I'm trying to send data from one component to another one without any success. I have one parent component App.vue and two child components Base.vue and Ingredients.vue. Mainly I' would like to send dynamic {{selectedBase.price}} (which is updated every time you select/deselect the option) from Base component to Ingredients component and being rendered on Ingredients component dynamically.
I imported and defined my-base and my-ingredients components on the main.js file
//App.vue <v-app light> <main> <v-container fluid> <v-flex xs12 sm6 offset-sm3> <my-base ></my-base> </v-flex> <v-flex d-flex xs12 sm6 offset-sm3 class="text-xs-center"> <my-ingredients></my-ingredients> </v-flex> </v-container> </main> </v-app> //Ingredients.vue <v-layout row v-for="ingredient in ingredients" :key="ingredient.id"> <v-layout column> <v-flex xs6 offset-xs5> <v-checkbox class="text-xs-right" name="checkbox" color="light-blue lighten-2" v-bind:label="`${ingredient.name}`" v-model="ingredient.checked" light></v-checkbox> </v-flex> </v-layout> <v-layout column> <v-flex xs6 offset-xs5> <v-subheader>{{ingredient.price}} €</v-subheader> </v-flex> </v-layout> </v-layout> <v-divider></v-divider> <v-layout row wrap class="mb-3"> <v-layout column> <v-flex xs6 offset-xs3> <h3 class="headline mb-0">Total price:</h3> </v-flex> </v-layout> <v-layout column> <v-flex xs6 offset-xs4> <v-subheader> {{total}} €</v-subheader> </v-flex> </v-layout> </v-layout> <script> export default { data: () => ({ checked1: '', showCart: false, ingredients: [{ id: 1, name: "Mozzarella", price: 2, checked: '', }, { id: 2, name: "Cheddar", price: 2.0, checked: '', }, { id: 3, name: "Bacon", price: 2.25, checked: '', }, { id: 4, name: "Mushrooms", price: 1.6, checked: '', }, { id: 5, name: "Pepperoni", price: 2.5, checked: '', }, { id: 6, name: "Sucuk", price: 2.75, checked: '', }], }), computed: { total: function() { var total = 0; for (var i = 0; i < this.ingredients.length; i++) { if (this.ingredients[i].checked) { total += this.ingredients[i].price; } } return total; } } } </script> //Base.vue <v-layout row wrap primary-title v-for="base in bases" :key="base.id"> <v-layout column> <v-flex xs6 offset-xs3> <v-avatar size="80px" class="grey lighten-1"> <img :src="base.href" :class="{selected: selectedBase.id == base.id}" @click="selectedBase = base" alt="avatar"> </v-avatar> </v-flex> </v-layout> <v-layout column> <v-flex xs6 offset-xs4> <v-subheader>{{base.name}} {{base.price}}€ {{selectedBase.price}}</v-subheader> </v-flex> </v-layout> </v-layout> </v-card> </template> <script> export default { data() { return { selectedBase: {}, bases: [{ id: 1, name: "Margarita", price: 4, href: "../../static/margarita.jpg" }, { id: 2, name: "Salami", price: 6, href: "../../static/salami.jpg" }] } }, computed: { totalBase() { var totalBase = 0; for (var i = 0; i < this.bases.length; i++) { if (this.bases[i].selected) { totalBase += this.bases[i].price; } } return totalBase; }, methods: { getSelectedBase() { return this.selectedBase; } } } } </script>Vue.js - Registering the Chart Component via Webpack
I have a Vue.js app. I am trying to use the vue-charts package. I'm importing the chart module in my index.js file like this:
import chartJS from 'chart.js'; import VueCharts from 'hchs-vue-charts'; Vue.use(VueCharts);Then, in my index.vue file, I have the following:
<template> <div class="page"> <h2>Hello</h2> <chartjs-line></chartjs-line> </div> </template> <script> export default { data() { return {}; } }; </script>The word "Hello" appears just fine. For that reason, I know that my app is being properly mounted. However, the chart does not appear. When I look in the devtools window, I see the following error:
Unknown custom element: - did you register the component correctly? For recursive components, make sure to provide the "name" option.
I assumed when I called Vue.use, the component would get registered. However, I'm clearly doing some wrong. Yet, I'm not sure what. How do I use the vue-charts components in my single file components?

Taking Pug/Jade mixin arguments from Vue script
Is it possible to bind mixin arguments to a vue instance?
I have this mixin to render a table:
mixin table(header,data,type) - var type = type || "" table.table(class=type) thead tr each head, i in header th #{head} tbody each row,j in data tr each col,k in row td #{col}Which can be used normally like this:
+table-striped(["#","First Name","Last Name","Username"],[["1","Mark","Otto","@mdo"],["2","Jacob","Thornton","@fat"],["3","Larry","the Bird","@twitter"]])My question is if it is possible to take the 'header' and 'data' arguments of the mixin from a vue instance.

And I can not retrieve it to display it elsewhere.

How to deploy a vuejs project to heroku
I am working on this project locally https://github.com/misterGF/CoPilot but now that it is finished, I would like to push it to heroku. the problem is telling heroku to start the app.
In the heroku example, the demo server runs after picking up the info from Procfile with contains this data

I only have the main entry point which is index.html and the procfile doesn't work with HTML.
Vuex state change propagation
I am a new to vuejs / vuex so I have a question about how vuex reactivity is supposed to function. I have the following store:
// state state: { database: { tables: [] } } // mutator ADD_TABLE(state, {table}) { state.database.tables.push(table); }So when the ADD_TABLE mutation happens vue components and the vuex watch react only when the object is directly changed and not reacting on nested property change.
// after the mutation happens store.watch(state => state.database, change => console.log(change)) // this doesn't log store.watch(state => state.database.tables, change => console.log(change)) // this doesIs this the desired behavior and why, or I have something breaking in my code?
Setting first array value as default checked radio button in Vue.JS
I need to set the first value in my array as the default checked radio button, but I'm having some issues. Currently I'm able to set the default as the last value in the same array, but that is not what I want. Any help would be appreciated!
<label class="calendar__transport-label" for="transportSelect">{{$t("message.transportLabel")}}</label> <div id="transportSelect" class="form-group calendar__transport-list calendar__radio"> <div class="calendar__transport-option" v-for="(amenity, amenityIndex) in calendar.amenities" :key="amenityIndex"> <label> <input name="transportRadio" type="radio" v-model="value" :value="amenity.id[0]" :checked="amenity.id[0] == currentAmenityId"> <span>{{amenity.description}}</span> </label> </div> </div>v-for : is there a way to get the key for the nested(second) loop besides "Object.keys(obj)[0]" in Vuejs?
Here's the markup:
<ul> <li v-for="(topic,label,index) in guides" :key="index"> <ul> <strong> {{label}} </strong> <li v-for="rule in topic"> {{rule.val}}, {{Object.keys(topic)[0]}} </li> </ul> </li>And here's the data for this list:
data: { guides: { "CSS" : { 1502983185472 : { "modifiedby" : "bkokot", "val" : "When adding new rule, use classes instead of ID whenever possible" }, 1502983192513 : { "modifiedby" : "bkokot", "val" : "Some other rule" }, }, "Other" : { 1502628612513 : { "modifiedby" : "dleon", "val" : "Some test text" }, 1502982934236 : { "modifiedby" : "bkokot", "val" : "Another version of text" }, } } }So as you can see there is a "guides" property which is an object of other objects that do have inner objects too. All I want is to get the keys from inner (second) loop (numbers "1502983185472" etc). The only solution that i see right now is "Object.keys(topic)[0]", but is there a more accurate alternative in vuejs for this? Adding key, index parameters to the second loop(with new unique variable names) doesn't work for me.
Here's a working fiddle: https://jsfiddle.net/thyla/yeuahvkc/1/
Please share your thoughts. If there is no good solution for this - may it be a nice topic for a feature request in Vuejs repo(unless I'm missing something terrible here)? Generally if you're curious - that number is a momentjs timestamp - I'm using this data in firebase, and saving initial timestamp as an object key seemed to be a pretty nice solution (since we need a key anyway, to save some space - I can use this key instead of another extra timestamp property in my object, this also makes the instance very 'targetable' in firebase).
Thank you in advance ! Cheers!
p.s: another possible solution is converting inner loop (css, other) from objects into arrays and using time-stamp as another object property, but I'm using firebase - saving this data as an object gives me an ability to quickly access some instance without parsing the entire parent object/array, makes it more easy to filter, search, reupdate, etc - thus converting object into array is not a good solution for instance with very large number of items.

Vue.js 2 does not update child when in hidden state
I have a page which renders a child component (chart) that is passed the data that fills the chart as a prop (list). It is being shown and hidden by a div that wraps it, and my problem is that when it is shown and my data (list) changes, it will properly redraw and update. But if it is hidden while the data changes, and then shown again, NOTHING draws at all in the space, it is blank, not even the previous chart. It looks roughly like this:
<div class="bluecards"> <div v-on:click="isShowpie = !isShowpie"> My clickable bar title that hides/shows Pie below </div> <div v-show="isShowpie" class="content"> <div class="chartwrapper"> <pie-chart v-if="loaded" :list="list" class="pchart"></pie-chart> </div> </div> </div>
