I have a laravel 5.4 application which uses VueJS 2.0 for the front end.

I'm trying to post the visitors array to the controller after populating on the page but when I return the array from the controller the data isn't there.

I can't see for the life of me what I'm doing wrong? What's interesting is if I send two visitors through I get two empty arrays returning from my controller so the number of visitors is working it's just not capturing the data.

My vue instance.

<script> new Vue({ el: '#app', data: { visitors: [], visitor: [], }, methods: { addVisitor() { this.visitors.push(this.visitor); this.visitor = []; }, storeVisit() { axios({ method: 'post', url: '/visit/new', data: { visitors: this.visitors } }); } }, }); </script>

My HTML page

<p>Visitors</p> <div class="columns"> <div class="column"> <input class="input" placeholder="First Name" v-model="visitor.first"> </div> <div class="column"> <input class="input" placeholder="Last Name" v-model="visitor.last"> </div> <div class="column"> <input class="input" placeholder="Company" v-model="visitor.company"> </div> <div class="column"> <input class="input" placeholder="Email" v-model="visitor.email"> </div> <div class="column"> <button class="button is-primary" @click="addVisitor()">Add</button> </div> </div>

I've then got a button that actions the storeVisit() method.

<button class="button is-primary" @click="storeVisit">Save Visit</button>

My controller waiting the post request

public function store(Request $request) { return $request->visitors; }

My response

{"visitors":[[],[]]}

We are building out a proof of concept multi-site / multi-tenancy SaaS app, using Firebase + VueJS, and are struggling on how best to secure application access based on a referring domain (source website).

In it's current structure there are two apps (projects) sharing one Firebase database. App1 is for account owners/management (accessed from a single domain eg. admin.abcwidgets.com) and App2 (app.abcwidgets.com) is serving content to iframes, loaded in from N+ third-party sites via some minimal JS inclusion code.

Securing individual multi-tenant data is not really a problem thanks to Firebase database rules - however we are struggling on how best to restrict the app to specific 'whitelisted' domains - set on a per-tenant basis. We currently pass an appKey to App2, which then checks whether the source domain is associated with the tenant's appKey - however we know this is not ideal as it can be easily spoofed/altered from the client side (or bypassed altogether) - allowing a site to potentially boot up an instance of another tenants app (assuming they know the correct keys etc).

Perhaps this extends beyond the scope of just Firebase (and is more a generic Javascript security question) - but i was wondering whether anyone can point me in the direction of an elegant solution that prevents an app initialising in this scenario. We are happy to add in 'middlemen', such as a Node.js server, if required.

Thanks in advance.

Basically i've made proyxy-component which renders different components based on what the :type is and it works great. The point is that I create a schema of the form controls and a separate data object where the data from the form controls is stored. Everything is working good but i have a problem when formData object contains nested objects.

In my example test.test1

How can i make the v-model value dynamic which is generated based on what the string is.

My Compoennt

<proxy-component v-for="(scheme, index) in personSchema.list" :key="index" :type="scheme.type" :props="scheme.props" v-model="formData[personSchema.prefix][scheme.model]" v-validate="'required'" data-vv-value-path="innerValue" :data-vv-name="scheme.model" :error-txt="errors.first(scheme.model)" ></proxy-component>

Data

data() { return { selectOptions, formData: { person: { given_names: '', surname: '', sex: '', title: '', date_of_birth: '', place_of_birth: '', nationality: '', country_of_residence: '', acting_as: '', test: { test1: 'test', }, }, }, personSchema: { prefix: 'person', list: [ { model: 'given_names', type: 'custom-input-component', props: { title: 'Name', }, }, { model: 'surname', type: 'custom-input-componentt', props: { title: 'Surname', }, }, { model: 'test.test1', type: 'custom-input-component', props: { title: 'test 1', }, }, { model: 'sex', type: 'custom-select-component', props: { title: 'Sex', options: selectOptions.SEX_TYPES, trackBy: 'value', label: 'name', }, }, ], }, }; },

I have a component

<template>somecode</template> <script> export default { name: 'Card', created() { axios.get(apiObjUrl) somecode }) } </script>

this my url: http://127.0.0.1:8080/#/card/12

But I have a problem:

when I use router-link like this:

<router-link to="/card/155"> card 155</router-link>

my url changes: http://127.0.0.1:8080/#/card/155

but the created() method doesn't get fired. so I don't make new xhr request to api and data not changes what do I do?

QA guys recently complained they can't automate frontend testing. Because our html looks all the same from outside. So as a lazy hack i did this

<template> <div :role="$options.name"> ... </div> </template>

Which just takes name from script and applies it in html.

Line :role="$options.name" goes in every component. Is there any DRYer solutions? Please share.

In my project, i have created and viewed the details of a room component.. I am in the need of doing edit functionality in it.. How to make edit in it and here are the following codes that i have tried,

I have to edit and update the values from the above codes.. The router link is directing to the edit page but i am not getting the value that was already in rooms.vue.

I am trying to pass a variable (here, externalVar) to a component, directly when initializing. But I can't find how to do it (probably not understanding documentation well :/ ). What is the correct way to do it?

The initialization :

var externalVar = "hello world" const leftmenu = new Vue({ el: "#left-menu", template: "<CLM/>", components: {CLM}, variableToPass: externalVar });

The component I am initializing here is defined like this (getting back variableToPass in data):

<template src="./template-l-m.html"></template> <script> import draggable from 'vuedraggable'; export default { name: 'leftmenu', components: { draggable }, data () { return { jsonObject: this.variableToPass, } }, [ ... ] </script>

But then , when I am trying to use this.jsonObject, it says that it's undefined. What am I doing wrong ?

I am new with vue.js and electrons and currently created my first app, now i just need to include my external css and js after reading some tutorials the i found out that best way to do this is importing it on my man.js, but failed on that part, is there another way of doing this other that importing it on my main.js? Any suggestion would be great thanks!

Already done below installations.

npm install bootstrap --save npm install jquery --save

My main.js code.

import Vue from 'vue' import axios from 'axios' import App from './App' import jQuery from 'jquery' global.jQuery = jQuery let Bootstrap = require('bootstrap') import 'bootstrap/dist/css/bootstrap.css' import store from './store' import VueRouter from 'vue-router' import test from './components/test' import Users from './components/users' Vue.use(VueRouter) const router = new VueRouter({ mode: 'history', base: __dirname, routes:[ {path: '/', component: Users}, {path: '/test', component: test} ] }); if (!process.env.IS_WEB) Vue.use(require('vue-electron')) Vue.http = Vue.prototype.$http = axios Vue.config.productionTip = false new Vue({ router, template: ` <div id="app"> <ul> <li><router-link to="/">Users</router-link></li> <li><router-link to="/test">Test</router-link></li> </ul> <router-view></router-view> </div> `, }).$mount('#app')

MY error is below, i am using electron-vue to make a native app.

I am working on this project which is an open source Vue.js and Firebase based CMS tamiat CMS. I want to integrate an admin section in it. After some search on google I found vue-admin which is vue.js based too.

Now, I am wondering How to integrate the two templates in order to both of them will run on the same vue instance ? is there any possible solution ?

I'm doing a filter page and I need to store the filter name and the filter value, for that purpose, I have a structure like that:

data: { attributes: { checkboxes: [], strings: { keys: [], values: [] }, ...

and the HTML would look like that (btw I'm using Laravel Blade too but that's not relevant here):

... @if ($atribut->type == 'checkbox') <label class="btn btn-default" for="{{ $atribut->tag }}"> {{ $nom }} <input v-model="attributes.checkboxes" class="badgebox" id="{{ $atribut->tag }}" type="checkbox" value="{{ $atribut->id }}"><span class="badge">&check;</span></label> <br> <br> @endif @if ($atribut->type == 'string') @php $nom = obj_array_find(DB::table('literals')->get(), $atribut->nom, 'id')->cat @endphp <input type="hidden" v-model="attributes.strings.keys" value="{{ $atribut->id }}"> {!! Form::text($atribut->tag, null, ['class' => 'form-control', 'placeholder' => $nom, 'v-model' => 'attributes.strings.values']) !!} <br> @endif ...

The question is, is it possible to have a something like that:

<input type="hidden" v-model.key="attributes.strings" value="{{ $atribut->id }}"> {!! Form::text($atribut->tag, null, ['class' => 'form-control', 'placeholder' => $nom, 'v-model.value' => 'attributes.strings]) !!}

the questions should be enough clear :). But I can see that something someone use:

<button @click="function()">press</button>

Someone use:

<button v-on:click="function()">press</button>

But really what is the difference between the two (if exists)

I have a vue application where i am using chart.js and i am trying to dynamically populate the chart from data in a table with a row click event.

This is what the function looks like and the chart.

var ctx = document.getElementById("myDoughnut"); var myDoughnut = new Chart(ctx, { type: 'doughnut', data: { labels: this.getAnalyticRow[0].rowNames, datasets: [{ data: this.getAnalyticRow[0].rowData, backgroundColor: [ 'rgba(255, 99, 132, 0.6)', 'rgba(54, 162, 235, 0.6)', 'rgba(255, 206, 86, 0.6)', 'rgba(75, 192, 192, 0.6)', 'rgba(153, 102, 255, 0.6)' ], borderColor: [ 'rgba(255,99,132,1)', 'rgba(54, 162, 235, 1)', 'rgba(255, 206, 86, 1)', 'rgba(75, 192, 192, 1)', 'rgba(153, 102, 255, 1)', 'rgba(255, 159, 64, 1)' ], borderWidth: 2, }] }, options: { responsive: true, defaultFontColor: '#ffffff', }

Not a duplicate: already check this question and this one; didn't get any clue. Some of similar ones are related to Laravel.

Can't figure out what was changed in my project, making [Vue warn]: Cannot find element: #app appear.

The structure:

index.html: hosts the <div id="app">:

[HEADER] <div id="app" v-cloak></div> [FOOTER]

main.js:

import Vue from 'vue'; import Users from './Users.vue'; import App from './App.vue'; // (1) import Home from './Home.vue'; // (2) import VueRouter from 'vue-router'; // (3) Vue.use(VueRouter); const routes = [ {path: '/users', component: Users}, {path: '/', component: Home} ]; const router = new VueRouter({ routes }); new Vue({ el: '#app', router, render: h => h(App) })

App.vue:

<template> <router-view> </router-view> </template> <script> export default { data () { return { message: "Test message" } } } </script>

Home.vue:

<template> [contents] [router-links] </template> <script> [data] [methods] </script>

Whenever I get to the index page, the Vue warn gets displayed. One of attached questions I checked suggested that the DOM element is not ready when scripts are running. Already tried to switch order of imports in main.js (App, Home and VueRouter, as marked in comments), but with no success.

Any idea where to look for solution?

Trying to generate a dynamic URL for a hyper-link, so that users can navigate to a specific customer page by ID.

<tr v-for="item in items" :key="item.id"> <td><a v-bind:href="generateCustomerUrl(item.id)" title="Navigate to Customer page"> {{ item.id }} </a> </td> ...

The function is declared in the module's methods

/** * Private methods for this vue class * **/ methods: { clearSearch() { this.filters.search = ''; EventBus.fire('apply-filters', this.serializedFilter); }, generateCustomerUrl(id) { return "/admin/customers/" + id; } },

However vue js errors saying

vm.generateCustomerUrl is not a function Stack trace:

How can I generate a URL dynamically for Vue.js 2.0 without using interpolation (which is disabled).

Why does filter do not work?

Error says: [Vue warn]: Failed to resolve filter: uppercase.

Not sure why but filter is not working. Also, is this the best way to code this functionality? Are there any ways to do this, or the suggested ways? I'm not sure about using the $refs, maybe I can do this simpler, but with effective use of reusable components.

I'm trying to emulate an Ajax Response by using random message and status instead.

I've bound a computed property to the src of an image tag in Vue.js. The code appears to correct, but does not work consistently which is baffling to me. Additionally, switching to the /about page and back to the main books page always properly displays the images.

Any information as to what could be causing this issue would be wonderful!

A hosted version of the app is available here: https://books.surge.sh/

The relevant code for the book-item component.

The full Github repo.

The code generating the book component and image src is as follows:

<template> <article class="book-item"> <img :src="imgSrc" class="image"> <div class="meta"> <div class="name">{{ book.title }}</div>* <div class="author">{{ book.author }}</div> </div> <div class="description"> <p v-html="book.description"></p> </div> </article> </template> <script> export default { props: ['book'], computed: { imgSrc() { return `/static/img/${this.book.image}`; } } }; </script>

Partially displayed book covers on initial load:

I am trying to make a type of progress bar to track a percentage of tasks completed. I want to v-bind:styles and pass it {width: dynamicWidth + '%'} in order to control the progression of this bar. So far I have created a computed variable that will return the percentage complete I want to bar to display, and I have set up my dynamic style in the data object

export default{ data: function () { return { numQuotes: dataBus.numQuotes, numberA: 30, barWidth: { width: this.barWidthCalculated +'%' } } }, computed: { barWidthCalculated: function(){ return this.numQuotes * 10; } } }

I also added an element to the DOM to see what was happening.

<div id="trackerBar"> <div id="trackerBarActual" v-bind:style="barWidth"> <h2>{{numQuotes}}/10</h2> <p>{{barWidthCalculated}}</p> </div> </div>

My bar stays fixed at 100%, i dont see any interpolation on the DOM. I also established another NUMBER variable in my data section and attempted to pass that to my width property, but still no change, and no rendering on the DOM. However if I pass any other elements in my styles object such as

color: 'red'

Those changes take place. Also if I pass my styles object a number directly ie...

barWidth: { width: 50 +'%' }

It displays correctly on the DOM.

What am I missing/doing wrong?

I have a Laravel / Vue app that I'm building and I've run into a bit of a snag. I have been able to successfully create individual stand-alone components, however when I try to nest a stand-alone component into another component, only the nested component shows up. A bit of code:

CompanyLogo.vue

<template> <figure class="company-logo" :style="{ width: size, height: size, backgroundImage: `url(${src})` }"></figure> </template>

LogoUploader.vue

<template> <div class="logo-container"> <company-logo size="65px" :src="`${company.logo.url}`"></company-logo> </div> <div class="logo-uploaded-details"> <p>Last updated: {company.logo.last_updated}</p> <button class="file-browse-btn">Upload Image</button> </div> </template>

What's happening is that when in company.blade.php I simply have

<logo-uploader></logo-uploader>

The app compiles and loads, however only the CompanyLogo shows up on the screen. The entire markup for the logo-uploaded-details section isn't rendered at all.

I have tried adding a require for the CompanyLogo component to the registration for the LogoUploader component, but that didn't work either.

If I split out the components they both show up. The issue is only once they're nested.

Any ideas?

So I'm new to Vuejs and doesn't know anything about npm, node, and other javascript apps.

I wanted to switch to VueJS so that I can take away from JQuery. Been using AdminLTE for my projects before.

I wanted to use vue-admin now since it seems to address all of my needs. However, I have specific work area situations that seems to hinder learning Vue and other JS apps, these are:

1. The workspace folder (development) where I'm creating applications is hosted in the production server (Windows Server).
2. I think NodeJS isn't installed in the server
3. Adobe Coldfusion is used. I don't have a local server, so the production server is used when developing.

Question:

1. Will the production server run the app built with vue-admin even if the production server doesn't have NodeJS installed? (I have NodeJS locally).
2. I need to use Coldfusion for the logic of the application, specifically I'm using CFWheels right now and vue-admin for Frontend and UX. Is it possible? The application I'm making is closely related to parts of an ERP system.
3. Any pointers on how I could do this?

Basically I want to be able to access some centralized data by setting up a dataBus as a vue instance object, and then access and tweak this data from different components.

I cant seems to access by data from my componenets, even basic string interpolation is not getting rendered to the DOM.

export const dataBus = new Vue({ data: { numQuotes: 4, stringVar: 'Hellow There' } });

I also tried setting up my data as the return of the function data(). But being as my data bus is an actual vue instance I don't think this is correct. (I could be wrong). Following is the component in which I import my dataBus and try to output my data.

<template> <div> <h1>Quotes Added</h1> <div id="trackerBar"> <div id="trackerBarActual"> <h2>{{numQuotes}}/10</h2> </div> </div> </div> </template> <script> import { dataBus } from '../main.js'; export default{ } </script>

I am getting the following error: Property or method "numQuotes" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option.

Am I missing something obvious? Is it even possible to access data this way? Or do I have to access it as a method?
