Onlangs vond ik via LinkedIn een advertentie voor de vacature ‘Senior Category Manager Domestic Appliances’ bij bol.com. Hierin stond zoveel wartaal dat ik het de moeite vond een ‘best of’ selectie te delen op Facebook. Daar vond men het ook erg grappig. Desondanks is het de moeite waard de vacature te decoderen: wat staat hier nou eigenlijk? Of exacter, wat bedoelen deze mensen. Komt ie. Update: Inhoudelijke reactie van bol.com in De Telegraaf

I have a problem where user needs to select countries first and then states and then cities. Now I have setup @change event on countries and states, as soon as the user selects country it fetches states and also @change on states is also triggered, and since I have state_id = '', now my getCities function fails.

<select v-model="country_id" @change="getStates()"> <option v-for="country in countries" :value="country.id">{{ country.name }}</option> </select> <select v-model="state_id" @change="getCities()"> <option v-for="state in states" :value="state.id">{{ state.name }}</option> </select> data(){ return{ countries: [], states: [], cities: [], country_id: '', state_id: '', city_id: '' } }, mounted(){ getCountries(); }, methods:{ getCountries(){ // this.countries = response.data } geStates(){ //get states where country_id = this.country_id }, getCities(){ //get cities where state_id = this.state_id //once country is selected even this is getting triggered } }

I'm working with a table display and am using vueJS to render a group of rows inside of a table. The bindings inside of the <tr> work fine, but I can't figure out how to bind say an attribute that lives on the parent <tr> that hosts the v-for directive:

<tr v-for="detailItem in itemList" data-key="{detailItem.pk}}"> <td>{{detailItem.cdesc}}</td> <td>{{(detailItem.nnetunits * 1).toFixed(2)}}</td> ... </tr>

In this code the inner items on the <td> bind just fine, but how would you get the data-key bound?

I want my components to share one piece of global data, which is a global variable that gets set via ajax when my main Vue instance is mounted. However, the component data is empty when I try to set it in the code below. How do I property set a component's data equal to a shared global object?

If it's an ajax problem, how would I get the component to wait for tableData to get set or have my component watch tableData for changes?

//Snippet of what gets return from ajax call { 121: { table_info: { id: "121", name: "Test", table_number: "51", cap: "6", seating: "OPEN", position_x: "0.19297285", position_y: "0.07207237", participants_in_tables: "5", count: 5 } } }

//Global var tableData; //This gets set when the Vue ajax call is complete after being mounted var width = $(document).width(); var height = $(document).height(); //Vue Vue.component('tables', { data: () => { return { tables: tableData } }, template: ` <div id="tableContain"> <div class='table' v-for="table in tables" :style="computeOffsets(table)"> {{table.table_info.name}} </div> </div> `, methods: { computeOffsets(table) { return { top: (table.table_info.position_x * width) + 'px', left: (table.table_info.position_y * height) + 'px' } } }); var app = new Vue({ el: '#main', mounted() { $.ajax({ method: 'POST', dataType: 'json', url: base_url + 'users/getTableAssignments/' + event_id }).done(data => { tableData = data; //Set global tableData }); } }); <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.js"></script> <div id="main"> <table></table> </div>

How can import custom js file from assets on vue js?

I try this;

<script src="./assets/js/dragging.js"></script>

But that's code not working.

Users can upload their ms word files, of which the text should be displayed on another page. My html and javascript(vuejs) is like this:

HTML

<form> <input type='file' v-on:click='retieve'> </form>

JS

retrieve: function retrieve(e){ var asfarasicansee = e.target.files[0] console.log(asfarasicansee)

This will return some file info as described here in the getting info paragraph: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/file

The only other thing I could find was this from 2001 and it only works in Internet Explorer, but my other code doesn't work in Internet Explorer: https://snook.ca/archives/javascript/copying_from_mi

Does anyone know how to work with MS word(or any other text editor) files? How do I retrieve the text from such documents?

HTML:

<div class="a"> Some HTML ... </div> <div class="b"> Some HTML </div>

Javascript:

new Vue({ el: "#item_info", .... .... (Other Config) .... .... })

The two div above need to show the information from vue,

I tried using <template></template> like:

<template> (my two div) </template>

but it not work because it need the root element.

I know that if I modify my html to:

<div id="item_info"> <div class="a"></div> <div class="b"></div> </div>

It can work, but I have no authorization to modify the base Html structure

Is there has other way can help me to solve it.

I have two separate components. In one component, I have an input, and on another component I want have a variable that is always equal to the input value. I don't want to bind it an event which will limit me to that event; I want to constantly watching it. Thus, I thought $emit is not a good option.

What is the appropriate way of achieving this?

Vue.component('first', { data: { helloVal: "Hello world" } template: ` <div> <input :hello="helloVal"> </div> ` }) Vue.component('first', { template: ` <div> <p>{{ helloVal }}</p> </div> ` })

How can I make hello to always be equal to helloVal? Can I use v-model: between separate components?

I'm using laravel framework.I installed npm and npm packages.ı run "npm run dev " Everything is okey. But ı cant use vuejs in blade. Im sure app.js file is correct. So vuejs file doesnt appear in web page's source code.And also ı installed sweetalert2 package . I followed instructions. I wrote in app.js like that import swal from 'sweetalert2' .but it looks comment line in my editor and it gives error when ı run npm run dev

I am creating a stock exchanger website with php using laravel frame work and MYSQL to solve realtime updating issue, I was thinking to use Vue.js but the problem is, if I setTimeOut 500 for getting latest data and there be more than 10,000 user in the exchange page it means every second I am sending 20,000 query to database to get all the data for each user.
My question is, is there any better way? For example I just update one file, and those users only load that file instead of using 20,000 MYSQL query every second?

In vue.js I have .vue component which has a watched data property isRunning. This component has a child component which also watches isRunning (accessed through its binding). Can I be assured that the watcher for the parent will be executed before the child's watcher?

I am on migrating to Vue from React, and I just liked the v-model thing Vue offers. Now I am in a situation and not able to find out what is the vue-ish way of doing this.

Here is how my component tree looks like:

- FormContainer -FormView - CustomInput - input

I have my states in FormContainer let's call it name and age. I want to avoid writing custom setter methods as I usually do using v-model, how can I go about passing the data down to the input component.

I should be able to do something like

<form-view @age="age" :age="age" @name="name" :name="name"/>

or something similar. Please let me know if you need more details on this.

I have the following script:

import Vue from 'vue' import Router from 'vue-router' Vue.use(Router) export default new Router({ scrollBehavior (to, from, savedPosition) { // purposely left blank }, routes: [ { path: "/", component: SampleComponent } ] }

I would like to add a handler (afterEach) to the router so that I can close any open menus when a router link is taken.

I tried to add it to the constructor but it is not a constructor argument. So I tried:

Router.afterEach((to, from) => { // ... })

But I get the error: "afterEach is not a function"

How do I appropriately add an afterEach callback with this setup?

Thank you in advance for your help.

I am using the node package p-queue (GitHub repo) in order to ensure that the axios.get requests from my app are sequential and at a max rate of 1 per second.

I need to add some requests to the queue depending on data from a previous request so I thought I would just loop over an array and add new axois promises to the p-queue according to the length of that array, but I keep getting odd errors

I cannot show the code directly, but here is a small example that has the same problem:

var ml = [1, 2, 3, 4] for (var i = 0; i < ml.length; i++) { promq.add(() => axios.get('http://example.org/' + ml[i])) .then(response => { console.log(response.data) }) }

This will correctly enqueue 4 promises and axios will correctly produce 4 http 404 responses, but that is because it is trying to visit not example.org/1, but instead it makes 4 requests for example.org/undefined

Why is this not working?

I am use vue 2.0.

<Poptip placement="right" width="400"> <Button type="ghost">click 激活</Button> <div class="api" slot="content">my content</div> </Poptip>

I need render function

render: (h, params) => { return h('Poptip', { props: { placement: 'right' } }, [h('Button', { props: { type: 'ghost' } }, 'Edit'), h('div', { props: { slot: 'content' } }, 'My content')]) }

if i using template it's work perfect But i used render function then slots content not replace with my content

I have a Login end point that respond me a json. I'm using vue-router to do a POST and then Store a token in localStorage, but after the POST, the json shows on the screen:

{"success":false,"message":"Login ou senha inválidos!"}

It should return on the page login, with the message

This is the code:

var vmLogin = new Vue({ el: '#login', data: { email: '', msg: '', password: '' }, beforeCreate: function () { if(localStorage.getItem("timeTaskToken") !== null) { window.location.href = '/' } }, methods: { getLogin: function (e) { this.$http.post('/login', {email: this.email, password: this.password}).then((response) => { alert('teste!'); if(response.body.success === true) { localStorage.setItem("timeTaskToken", response.body.token); window.location.href = '/' } else { this.msg = response.body.message } }, (response) => { // error callback }); e.preventDefault(); } } });

login page

<form id="login" class="form-horizontal" method="post"> <h3>{{ msg }}</h3> <div class="form-group"> <label for="inputEmail3" class="col-sm-2 control-label">Email</label> <div class="col-sm-10"> <input type="email" v-model="email" class="form-control" name="email" placeholder="Email"> </div> </div> <div class="form-group"> <label for="inputPassword3" class="col-sm-2 control-label">Password</label> <div class="col-sm-10"> <input type="password" v-model="password" class="form-control" name="password" placeholder="Password"> </div> </div> <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <div class="checkbox"> <label> <input type="checkbox"> Remember me </label> </div> </div> </div> <div class="form-group"> <div class="col-sm-offset-2 col-sm-10"> <button type="submit" class="btn btn-default" @click="getLogin">Sign in</button> </div> </div> </form>

It's like nothing after .then works...

The returned JSON just appear in the screen.

I am starting with the snippets in this question How to use multiple vue components on single page? The following example works with vue build app.vue, but it does not work if I set up a simplest server and visit index.html.

index.html:

<!DOCTYPE html> <html> <head> <title>Test</title> <meta charset="utf-8"> <script type="text/javascript" src="jspm_packages/system.js"></script> <script type="text/javascript" src="config.js"></script> </head> <body> <div id="app"></div> <script type="text/javascript"> System.import('app.js'); </script> </body> </html>

app.js:

import Vue from 'vue/dist/vue.js' window.onload = function() { new Vue({ el: '#app', render: h => h(app) }) }

app.vue:

<template> <qwop></qwop> </template> <script> import qwop from 'qwop.vue' export default { components: { 'qwop': qwop } } </script>

qwop.vue:

<template> <div>Hello</div> </template>

Through running vue build app.vue, a web server is launched and I can see "Hello" in the web page. But nothing shows if I create a web server by for example python -m http.server and visit index.html. Anything wrong with my index.html and app.js?

I have a loop like this:

<div class="jokes" v-for="joke in jokes"> <strong>{{joke.body}}</strong> <small>{{joke.upvotes}}</small> <button v-on:click="upvote"><i class="fa fa-arrow-down"></i></button> <div>

I need to get joke.id so that I can post it to backend and increment the votes.

The method should be something like this:

methods: { upvote: function(e) { axios.post( this.BASE_URL + "/api/joke/" + this.joke.id + "/upvote", { token: 'secret', }).then(function(data){ console.log(data); }); } },

How can I achieve this?

Some Context... I have a list of players in a hockey league. For each game played I want to save a gamesheet with the players of the home team and visiting team that would include their game stats. I want the player .key from the full list of players to match the player .key of the stored gamesheet.

The issue I'm having is storing the array of the home/visitor teams to Firebase. The array for 'homeTeam' is the following:

[ { "name": "Steve", "number": "10", "position": "F", ".key": "-KrbKovnJe2uxU2h1Aec" }, { "name": "Carl", "number": "32", "position": "F", ".key": "-KrbKovnJe2uxU2h1Aec" } ]

I can save individual records with the following:

gamesheetRef.child(gameinfo['.key']).child('home').child(this.homeTeam[0]['.key']).set({name: this.homeTeam[0].name})

This saves as the correct structure in Firebase:
- gamesheet - -KonukQ9Pf7ksy9jvgo3 - home - -KrbKovnJe2uxU2h1Aec - name: "Steve"

How can I save the entire array like this, using the .key(s) from the array?

I'm using the vue-cli webpack template and I'm trying to load in local fonts in my project. I'm having trouble getting the path to my fonts correct. How should my path look like?

I found some information about what I might be doing wrong but I couldn't figure it out: https://github.com/webpack-contrib/sass-loader#problems-with-url

File structure:

In my _fonts.scss:

// Webfont: LatoLatin-Regular @font-face { font-family: 'LatoLatinWeb'; src: url('../assets/fonts/LatoLatin-Regular.eot'); /* IE9 Compat Modes */ src: url('../assets/fonts/LatoLatin-Regular.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */ url('../assets/fonts/LatoLatin-Regular.woff2') format('woff2'), /* Modern Browsers */ url('../assets/fonts/LatoLatin-Regular.woff') format('woff'), /* Modern Browsers */ url('../assets/fonts/LatoLatin-Regular.ttf') format('truetype'); font-style: normal; font-weight: normal; text-rendering: optimizeLegibility; }

Webpack.base.config.sj:

{ test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/, loader: 'url-loader', options: { limit: 10000, name: utils.assetsPath('fonts/[name].[hash:7].[ext]') } }

Utils.js:

return { css: generateLoaders(), postcss: generateLoaders(), less: generateLoaders('less'), sass: generateLoaders('sass', { indentedSyntax: true }), scss: generateLoaders('sass').concat( { loader: 'sass-resources-loader', options: { resources: path.resolve(__dirname, '../src/styles/_variables.scss') } } ).concat( { loader: 'sass-resources-loader', options: { resources: path.resolve(__dirname, '../src/styles/mixins/_mixins.scss') } } ).concat( { loader: 'sass-resources-loader', options: { resources: path.resolve(__dirname, '../src/styles/_fonts.scss') } } ), stylus: generateLoaders('stylus'), styl: generateLoaders('stylus') }

How do I load my local fonts in with vue-cli webpack template?
