you have not declared vue-infinite-loading
import InfiniteLoading from 'vue-infinite-loading';

In my vue app I have 2 methods, one method gets some data from my laravel backend and the second one needs to be able to grab it so that I can use it in that method.
What I'm struggling with is that the second method isn't grabbing the data.
Here is my code
<template>
<app-layout>
<div class="content-wrapper" style="margin-left: 0;">
<div class="content">
<div class="container">
<div class="row pt-5">
<div class="col-lg-12">
<div class="card">
<div class="card-body">
<div class="row">
<div class="col-lg-12">
Some data will show here
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</app-layout>
</template>
<script>
import AppLayout from '#/Layouts/AppLayout'
export default {
components: {
AppLayout,
},
data() {
return {
testData: ''
}
},
methods: {
firstMethod() {
axios.get('/api/get-data').then(response => {
this.testData = response.data;
});
},
secondMethod(){
console.log(this.testData);
}
},
mounted() {
this.firstMethod();
this.secondMethod();
}
}
</script>
your running both function in mount function so both run at same time and secondMethod() executed 1st at that time your this.testData is not set so you can use async and await to wait to finish firstMethod() then run secondMethod()
which will be like below code
<template>
<app-layout>
<div class="content-wrapper" style="margin-left: 0">
<div class="content">
<div class="container">
<div class="row pt-5">
<div class="col-lg-12">
<div class="card">
<div class="card-body">
<div class="row">
<div class="col-lg-12">
Some data will show here
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
</app-layout>
</template>
<script>
import AppLayout from "#/Layouts/AppLayout";
export default {
components: {
AppLayout,
},
data() {
return {
testData: "",
};
},
methods: {
async firstMethod() {
const { data } = await axios.get("/api/get-data");
this.testData = data;
},
secondMethod() {
console.log(this.testData);
},
},
async mounted() {
await this.firstMethod();
this.secondMethod();
},
};
</script>
You can try calling firstMethod in created() hook instead of mounted. In my opinion you do not need a method for modifying incoming data. Use watch instead:
watch: {
// whenever question changes, this function will run
testData: function (newValue) {
// do what transformation you need here
}
}
Watch hooks run when value of variable changes, so it should run when it is assigned.
The problem that you dont see the console log is because even if you execute first the first method, it's actually executed after the second method because takes more time to be resolved.
Try the below please, inside first method i added after then to execute the second method which means that that the first method would be resolved, thus we will have the api response.
In case you continue seeing nothing from console log then there is an issue with the api endpoint.
mounted() {
this.firstMethod();
},
methods: {
firstMethod() {
axios.get('/api/get-data').then(response => {
this.testData = response.data;
this.secondMethod();
});
},
secondMethod(){
console.log(this.testData);
}
},
I'm working on an application to manage some Cvs.
All my resource functions work perfectly (creating and editing new Cvs etc.)
But in my Vue.js part, it's about showing details for every Cv in a show view using Axios to get data from the database or post using a form.
My console shows a reactivity problem about my variables: infos and info.
Here is my show.blade.php code:
#extends('layouts.app')
#section('content')
<div class ="container" id="app">
<div class="container" id="app">
<div class ="row">
<div class="col-md-12">

<div class="col-md-2 text-right">

</ul>
</div>

<script>
window.Laravel={!! json_encode([
'csrfToken' => csrf_token(),
'idExperience' => $id,
'url' =>url('/')]) !!} ;
</script>
<script>
var app= new Vue({
el:'#app',
data:{
message: '',
infos: [],
info:{

cv_id:window.Laravel.idExperience,
titre:'',
body:'',
}},
methods:{
getExperiences: function() {
axios.get(window.Laravel.url+'/getexperiences/'+window.Laravel.idExperience)
.then(response=>{
console.log(reponse.data);
this.info=reponse.data;})
.catch(error =>{
console.log('errors: ', error);})},
addExperience:function(){
axios.post(window.Laravel.url+'/addexperience', this.info)
.then(repsonse => {
if(response.data.etat){
this.infos.unshift(this.info);

titre:'',
body:'',
};}})
.catch(error =>{
console.log('errors: ', error)})},
created:function(){
this.getExperiences();})};
</script>
#endsection
And my two functions get Experiences and addExperience in CvController:
public function getExperiences($id){
$cv= Cv::find($id);
return $cv->infos;
}
public function addExperience(Request $request){
$info = new Info;
$info->titre=$request->titre;
$info->body=$request->body;
$info->cv_id=$request->cv_id;
$info->save();
return response()->json(['etat'=> true, 'id'=> $info->id]);
}
And these are my routes:
Route::resource('cvs','CvController');
Route::get('/getexperiences/{id}', 'CvController#getExperiences');
Route::post('/addexperience', 'CvController#addExperience');
My console:
There are some syntax errors that need to be fixed first.
There's an extra ")" at the end of your created method
The methods property is missing a closing "}"
There's a missing ")" at the very end to match the opening new Vue( parenthesis.
It's helpful to indent your code to make these things easier to spot.
Then, you'll need to update your data to be a function that returns an object. See Vue Docs - Data Must Be a Function
You also have some typos for the "response" variable.
Lastly, in your HTML you have two divs that have id="app".
Your JS should look something like:
var app = new Vue({
el: '#app',
data: {
message: '',
infos: [],
info: {
id: 0,
cv_id: window.Laravel.idExperience,
titre: '',
body: '',
}
},
methods: {
getExperiences: function () {
axios.get(window.Laravel.url + '/getexperiences/' + window.Laravel.idExperience)
.then(response => {
console.log(reponse.data);
this.info = response.data;
})
.catch(error => {
console.log('errors: ', error);
})
},
addExperience: function () {
axios.post(window.Laravel.url + '/addexperience', this.info)
.then(response => {
if (response.data.etat) {
this.infos.unshift(this.info);
this.info = {
id: 0,
cv_id: window.Laravel.idExperience,
titre: '',
body: '',
};
}
})
.catch(error => {
console.log('errors: ', error)
})
},
created: function () {
this.getExperiences();
}
}
});
Let me know if that works for you.
I am new to Laravel and a complete noob to Vue. I searched many other Laravel/Vue posts but none seemed to be similar enough to get me to a solution. When attempting to load this component on my view I receive the following error
app.js:32654 [Vue warn]: Property or method "features" is not defined on the instance but referenced during render. Make sure to declare reactive data properties in the data option.
Please let me know what I am missing.
chrome.google.com/webstore/detail/vuejs-devtools/ shows that Vue is loaded
I would like to load data from an ajax call to my vue component. that can be updated on the fly by event handler
App.js
window.Vue = require('vue');
Vue.component('Example', require('./components/Example.vue'));
const app = new Vue({
el : '#app',
});
$(document).ready(function() {
$.ajaxSetup({
headers : {
'X-CSRF-TOKEN' : $('meta[name="csrf-token"]').attr('content')
}
});
})

The features array must be declared either as a prop or part of the component data.
As a prop:
<template>
<div class="container projects-container">
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
<div class="panel-heading">Example Component</div>
<div class="panel-body">
<h1>I'm an example component!</h1>
<ul class="list-group">
<li class="list-group-item" v-for="feature in features">
{{ feature.properties.name }}
</li>
</ul>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
mounted() {
console.log('Component mounted.')
},
props: ['features']
}
</script>
As component data:
<template>
<div class="container projects-container">
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
<div class="panel-heading">Example Component</div>
<div class="panel-body">
<h1>I'm an example component!</h1>
<ul class="list-group">
<li class="list-group-item" v-for="feature in features">
{{ feature.properties.name }}
</li>
</ul>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
mounted() {
console.log('Component mounted.')
},
data: function() {
return {features: []}
}
}
</script>
If you use a prop, you'll need to bind the prop in the template. If you use component data, you'll need to update the success callback function in the AJAX request to correctly update the data of the component rather than the app as a whole.
Also, beware of the reactivity caveats for loading new data, as outlined in the docs.
EDIT: Full example solution using component data
Here's a working example using a simplified version of your example component. Note that to do this I used the ref attribute so that the component could be addressed directly. Using refs is described in the docs as an "escape hatch" that should only be used when strictly necessary. A better pattern might be an external store, such as Vuex.
Vue.component( "example", {
template: '<div><h1>Example Component!</h1><ul v-if="features.length"><li v-for="feature in features">{{ feature.name }}</li></ul></div>',
data: function() {
return { features : [] }
}
});
var app = new Vue( { el: '#app' });
//A function to represent the AJAX callback
var doMockAjax = function() {
var mockData = [{name: 'One'},{name: 'Two'},{name: 'Three'}];
app.$refs.example.features = mockData;
}
document.getElementById('load-data').addEventListener('click', function(e) {
//This simulates the ajax callback by populating the array asynchronously
setTimeout(doMockAjax,1000);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.min.js"></script>
<div id="app">
<example ref="example"></example>
</div>
<button id="load-data">Load</button>
I made an autocomplete component and it works well in Chrome, but not in IE and Safari.
It displays the template twice in IE and Safari. It works but it shows the template in addition to the rendered HTML. See the image.
What did I do wrong?
<div id="main">
<autocomplete></autocomplete>
</div>
<template id="autocomplete">
<div>
<div class="col">
<section class="box clr1">
<div>
<div>
<input type="text" placeholder="Welk product zoekt U?" v-model="query" v-on:keyup="autoComplete" class="form-control">
<div class="panel-footer" v-if="results.length">
<ul class="list-group">
<li class="list-group-item" v-for="result in results">
<span style="text-decoration: underline;cursor:pointer" v-on:click="showDetail(result.id)">#{{ result.title }}</span>...
<div class="col">
<section class="box clr1">
<div>
<div v-for="detail in resultdetail">
<h1>#{{ detail.title }}</h1>
<h2>#{{ detail.page_title }}</h2>
<p v-html="detail.description"></p>...
Vue.component('autocomplete', {
template: '#autocomplete',
data: function () {
return {
show: false,
query: '',
results: [],
resultdetail: []
}
},
methods: {
autoComplete: function () {
this.results = [];
if (this.query.length > 1) {
axios.get('/getproductjson/' + this.query + '/0')
.then(function (response) {
this.results = response.data
}.bind(this))...
showDetail: function (productId) {
if (productId > 0) {
this.show = true;
this.resultdetail = [];
axios.get('/getproductjson/loremipsumdipsum/'+productId)
.then(function (response) {
this.resultdetail = response.data
}.bind(this))...
}
});
new Vue({
el: '#main'
});
Result:
Internet explorer does not support the template tag.
What you're seeing in Internet Explorer is your instantiated Vue, and, since IE doesn't implement template it just shows your template on screen.
In IE if you want to store your template in the DOM you typically have to use the a script template.
<script type="text/x-template" id="autocomplete">

I have a Laravel 5.4 project.
I have created two components : Students.vue and Student.vue component
Students.vue get all the students and Student.vue the markup for one display of a student
here is my Students.vue
<template>
<div v-if = "students.length && meta">
<pages :pagination = "meta"></pages>
<div class = "col-lg-3 col-sm-6 col-md-4 music_genre" v-for = "student in students">
<student :student = "student"></student>
</div>
</div>
</template>
<script>
import { mapActions, mapGetters } from 'vuex'
import eventHub from '../../events.js'
export default {
methods: {
...mapActions({
getStudents: 'student/getStudents'
})
},
computed : {
...mapGetters ({
students : 'student/students',
meta : 'student/meta'
})
},
mounted() {
this.getStudents(1)
}
}
</script>
here is my Student.vue
<template>
<div class="">
<div class="team-info ">
<h4>
<a href="#">
{{student.name}} {{student.last_name}}
</a>
</h4>
<span class='team-member-edit'>
<i class='fa fa-pencil icon-xs'></i>
</span>
</div>
<p>Along with studies, is good in all around activities held in the university events.</p>
</div>
</template>
<script>
export default {
props:['student'],
mounted() {
}
}
</script>
When i click on the Student Name, I would like to display all the details of the student. How to achieve that
I assume you have a key differentiating each students, hence you can do this
'/students/:id': {
component: 'student'
}
