pass a variable inside an array to update that variable dynamically - in Vue.js
i'm trying to change variables dynamically so as not to use too many switch statements. i was hoping to do this:
this.variable1 = 2 this.variable2 = 3 var array1 = [this.variable1, this.variable2]and then later do
array1[0] = 25 array1[1] = 12 console.log(array1[0]) //would output 25 console.log(array1[1]) // would output 12of course it this is not what happens which is normal but how can i achieve that dynamically? There must be a way i'm sure.
How can I display modal in modal on vue component?
My view blade like this :
<a href="javascript:" class="btn btn-block btn-success" @click="modalShow('modal-data')"> Click here </a> <data-modal id="modal-data"></data-modal>If the button clicked, it will call dataModal component (In the form of modal)
dataModal component like this :
<template> <div class="modal" tabindex="-1" role="dialog"> <div class="modal-dialog" role="document"> <!-- modal content data --> <div class="modal-content modal-content-data"> <form id="form"> <div class="modal-body"> ... </div> ... <button type="submit" class="btn btn-success" @click="add"> Save </button> ... </form> </div> <!-- modal content success --> <div class="modal-content modal-content-success" style="display: none"> <div class="modal-body"> ... </div> </div> <!-- modal content failed --> <div class="modal-content modal-content-failed" style="display: none"> <div class="modal-body"> ... </div> </div> </div> </div> </template> <script> export default{ ... methods:{ add(event){ const data = { ... } this.$store.dispatch('add', data) .then((response) => { if(response == true) this.$parent.$options.methods.modalContent('#modal-data', '.modal-content-success') else this.$parent.$options.methods.modalContent('#modal-data', '.modal-content-failed') }) .catch(error => { console.log('error') }); } } } </script>If response = true then modal with class = modal-content-success will appear
If response = false then modal with class = modal-content-failed will appear
I want if response = false, modal with class = modal-content-data still showing. So modal with class = modal-content-failed appears in modal with class class = modal-content-data
How can I do that?
How to order that when response = false, modal with class = modal-content-data still appear?
Vuejs - How to render vnodes of child components when using slots
How does one render vnodes from a parent component of its child components. I have a render function that is looping through an array of children found in this.$slots.default. The aim is to wrap the children in li tags.
The problem is that the children components don't render and I get empty li tags. What am I missing here and where can the solution be found in the documentation. The Fiddle Can be found here And the embedded code is below.
// Parent component const MyParent = Vue.component('my-parent', { render: function(createElement) { var parentContent = createElement('h2', "These are Parent's Children:") var myChildren = this.$slots.default.map(function(child) { //console.log("Child: ", child) return createElement( 'li', child ) }) var content = [].concat(parentContent, myChildren) return createElement( 'div', {}, content ) } }); // Child Component const MyChild = Vue.component('my-child', { template: '<h3>I am a child</h3>' }); // Application Instance new Vue({ el: '#app', components: { MyParent, MyChild } }) <script src="https://unpkg.com/vue/dist/vue.js"></script> <div id="app"> <my-parent> <my-child></my-child> <my-child></my-child> </my-parent> </div>

Manully add csrf token With Slim ,Axios and ForData
I have a a modal that would submit a file without using an actual form, I am using FormData, so upload it to server. This will work if csrf token is disabled, my question is, how would I send the csrf token manually? I am using slim,axios and vuejs.
var formData = new FormData(); formData.append('fileme',file); axios.post(uyab.uploadUrl, formData,{ headers: { 'Content-Type': 'multipart/form-data', 'csrf_name': uyab.csrf_name, 'csrf_value': uyab.csrf_value, 'Accept': 'application/json', }, })But this will return error of failed csrf token
I created a function that would fetch csrf name and values from specific routes, and thus returning with correct values, the only problem is I dont know how to make it work in vuejs using spa approach

[Vue warn]: Unknown custom element: <testimonial-photo-inner>
I have just installed VueJS on my website and I'm getting tonnes of console errors like the one above. I am not trying to create any Vue components (yet) but my website does contain a number of custom HTML tags.
Does Vue treat any custom HTML tage (e.g. not one in the HTML spec) as something it needs to compile and will it always complain about tags it doesn't recognise?
Is it possible to switch theses warning off?
Please note: This is not a duplicate of Vue js unknown custom element
The user there is actually trying to create a Vue component.
Cannot access 'this' in TypeScript Vue Component constructor
I had been doing something like this for a long time:
@Component({ template, name: 'Something' }) export class Something extends Vue { someParam: string; constructor() { super(); this.someParam = this.$route.params.someParam; } }I'm not which one affected the change, but since upgrading to:
"vue": "~2.4.2", "vue-router": "~2.7.0", "typescript": "~2.4.2",Now I get this error:
[Vue warn]: Error in data(): "TypeError: Cannot read property '_route' of undefined" vue.esm.js:566 TypeError: Cannot read property '_route' of undefinedNone of my code changed, so what changed in Vue or TypeScript (or anything else), why did this stop working, and how can I fix it?
I started moving these to beforeCreate() but they are all over the application, so it's a significant change if I can't find a fix that doesn't require a major refactor.
Thanks
vuejs get data on <input type="hidden"

I tried to integrate flash messaging using the session variable. The problem is that when I integrated Vue, the window stopped receiving the event.
From the controller:
return redirect('home') ->with('flash', 'Signed');And on my app.js:
window.Vue = require('vue'); window.events = new Vue(); window.flash = function (message) { window.events.$emit('flash', message); };I think the important part of the Vue component is this line here:
created() { window.events.$on( 'flash', (message) => this.flash(message) ); }If I type flash('message') in the console, I will see a flash message pop up and it will appear as an event in the Vue Dev Tools.
But for some reason it's not getting it from the controller. Any ideas?
VueJS - Rest call in unit test
I'm making a rest call and saving the response to expectedServices, however it doesn't seem to be ready when I test it (says its undefined).
it(`should get the serviceList from /services endpoint`, done => { // Extend the component to get the constructor, which we can then initialize directly. const Constructor = Vue.extend(Products); const comp = new Constructor().$mount(); var expectedServices; axios.get('http://localhost:9090/services') .then((resp) => { expectedServices = resp.data; }) .catch((err) => { expectedServices = resp.data; }) Vue.nextTick(() => { expect(JSON.stringify(comp.serviceList)).to.equal(JSON.stringify(expectedServices)); done(); }); });FeathersJS and VueJS 2 coexistence (repo)
I want a simple way to have scaffolded versions of feathers and vue, where they both use their -cli utilities, but in such way they don't mess with each other, but can be deployed at once. Requisites:
- I don't feathers-js to recompile things because something changed in the vue sub-folder.
- I want to deploy everything to heroku and build as it is just one thing (that is, only one "package.json", only one "npm start".
- I want to use express capabilities of feathers to not only provide the rest/sockets services but also, serve the html/vue-bundled-js.
I've seen several examples where you just create one "server" and one "client" folder, which is great for separation between client-server, but then... how do you include the vue app bundle into the feathers served static (public) and to make all happen seamlessly.
Also please let me know if I'm wrong with any of my "requirements" (a.k.a.: I should change my mindset).
How to seperate Vue logic in a laravel app based on layout and page templates
I have a laravel app and a Vue instance attached to the body (or a div, just inside the body).
const app = new Vue({ el: '#app' });I think it makes sense to use the Vue instance for stuff relating to the layout (eg header, nav, footer logic).
Now I have a form that is visible on a specific route (e.g. example.com/thing/create). I want to add some logic to it, e.g. hiding a field based on selected option in the form. It is logic meant for just this form (not to be reused). I prefer not to put all the logic inline with the form but put it in the app.js. I could put it in the Vue instance bound to the body but that sounds odd as it only applies to the form that is much deeper into the dom.
I want to leave the markup of the form in the blade template (that inherits the layout).
I tried creating a component but am not sure how to bind this inside the main Vue instance. What is the best way to handle things for this form, put it in the app.js and have it somewhat structured, putting the variables somewhat into scope. Or is it really necessary to remove the main Vue instance bound to the full layout code?
What I tried was something like this, but it does not work (attaching it to the <form id="object-form"> seems to fail:
var ObjectForm = { template: function() { return '#object-form'}, data: function() { return { selectedOption: 1 } }, computed: { displayField: function() { // return true or false depending on form state return true; } } };Things do work if I remove the #app Vue instance or when I put everything directly in the app Vue instance. But that seems messy, if I have similar variables for another form they should be seperated somewhat. I would appreciate some advice regarding the structure (differentiate page layout and page specific forms) and if possible some example to put the form logic inside the main app.js.
Testing API call in Vue with Moxios
I am having trouble figuring out how to test an API call that happens in the "mounted" lifecycle hook.
I have a single file component that is responsible for displaying some information about an "Owner".
This works exactly how I want / expect in the browser.
<template> <div> <h3>Owner Information</h3> <table class="table table-striped table-condensed"> <thead> <th>Name</th> <th>Address</th> <th>Social Security Number</th> <th>Ownership Percentage</th> </thead> <tbody> <tr :data-owner-id="owner.id" v-for="owner in owners"> <td>{{ owner.name }}</td> <td>{{ owner.address }}</td> <td>{{ owner.censored_ssn }}</td> <td>{{ owner.ownership_percentage }}</td> </tr> </tbody> </table> </div> </template> <script> import axios from 'axios'; export default { data() { return { principal_id: '', owners: [] } }, mounted() { const el = document.querySelector('#owner-information'); this.principal_id = el.dataset.principal; var self = this; axios.get(`/principals/${this.principal_id}.json`).then(response => { response.data.owners.map((owner) => { owner.score = ''; owner.link = ''; owner.last_pull_date = ''; self.owners.push(owner); }); }); .catch(e => { console.log(e); }); } } </script>For testing, I am using Karma, Jasmine, and Avoriaz.
Here is a failing test:
import { mount } from 'avoriaz' import OwnerInformation from '../../app/javascript/packs/OwnerInformation.vue' describe('OwnerInformation', () => { let component beforeAll(() => { const element = document.createElement('div') element.setAttribute('id', 'owner-information') element.setAttribute('data-principal', '84033') document.body.appendChild(element) component = mount(OwnerInformation) component.vm.$mount('#owner-information') }) it('retrieves owner information from the API', () => { expect(component.data().owners.length).toBe(1) }) })The above expects 1, but gets 0.
So now I figure that I need to stub/mock out my API request in some manner. A quick Google search leads me to moxios. So I install it with Yarn and eventually come up with this. I am not 100% sure where to put moxios.stubRequest, but have tried putting it in beforeAll(), beforeEach(), and inside the "it".
```
import moxios from moxios import { mount } from 'avoriaz' import OwnerInformation from '../../app/javascript/packs/OwnerInformation.vue' describe('OwnerInformation', () => { let component beforeAll(() => { const element = document.createElement('div') element.setAttribute('id', 'owner-information') element.setAttribute('data-principal', '12345') document.body.appendChild(element) component = mount(OwnerInformation) component.vm.$mount('#owner-information') }) beforeEach(() => { moxios.install() }) afterEach(() => { moxios.uninstall() }) it('retrieves owner information from the API', () => { moxios.stubRequest('/principals/12345', { status: 200, response: { id: 1, owners: [ { name: 'Test Owner', address: '123 Test St.', ssn: '123-12-1234', ownership_percentage: 100 } ] } }) expect(component.data().owners.length).toBe(1) })It appears that the request is not actually be stubbed out. To troubleshoot, I put a console.log statement just before the axios.get() call (which logs out successfully) and I also put a console.log to log out the response, but this one never shows up which makes me think that the axios request is not working and is not getting "intercepted" by moxios.
... console.log('CALLING API...') axios.get(`/principals/${this.principal_id}.json`).then(response => { console.log('***********************') ...When I run the test I do see a 404, but am unsure why:
01 08 2017 12:49:43.483:WARN [web-server]: 404: /principals/12345.json
To me, it makes most sense to stub out the request at the top of beforeAll(), but this does not work either.
How can I arrange this so that moxios stubs out the API request and it returns so that my test passes?
Handling form submission without replacing template in VueJS
First of all, please be kind. I'm new to VueJS coming from the Angular world where things are different ;-)
I am creating a multi-page website using VueJS for simple things like a floaty header and submission of forms etc. I'd like the markup for my contact form to be in my HTML (rendered by the CMS) and I'd like to have VueJS handle the form submission and replacing the form with a thank-you message. So, a simplified version of the form would look like this.
<contact-form> <form class="contact-form_form"> ... <input name="emailaddress" type="text" /> ... <button></button> </form> <div class="contact-form_thanks"> Thanks for filling in this lovely form </div> </contact-form>So, the obvious thing to do is to create a VueJS component, but I don't want it to introduce a new template, I just want it to submit the form when the button is pressed (using Axios) and hide the form and show the thank you message.
I know how to do all of this in angular using attribute directives and ng-show/hide etc. but can't really see how to do this in VueJS because all the tutorials are geared to wards SPAs and Single file components with templates.
Any kick in the right direction would be appreciated.
