Attributes not rendered when running xpage:
:Source code:
<div id="categories" class="article-search-results-categories">
<ul class="table-view">
<li class="table-view-cell pr40" v-for="row in list.categories">
<xp:span id="clickSpan">{{row.name }}
<xp:this.attrs>
<xp:attr name="v-on:click" value="alert('ok')" rendered="true"
</xp:attr>
</xp:this.attrs>
</xp:span>
</li>
</ul>
</div>
Script
var app = new Vue ({
el: '#app',
data: {
list:[]
},
methods:{
getUsers: function(){
var link = 'https://jsonplaceholder.typicode.com/users';
this.$http.get(link).then(function(response){
this.list = response.data;
}, function(error){
console.log(error.statusText);
});
},
getCategoryJSON: function(){
var config = {
headers : {
'Content-Type' : 'application/json'
}
}
var data = {
"supplierid": "DAHL"
};
data = JSON.stringify(data);
axios.post
('ProductViewJSONCtrl.xsp',data,config).then(function(response){
app.list = response.data;
}, function(error){
console.log(error.statusText);
});
},
getLevel: function(row){
console.log('clicked');
}
},
mounted : function(){
console.log("in mounted");
this.getCategoryJSON();
}
});
Output:
<span id="view:_id1:_id2:_id295:includeBody:_id328:clickSpan">VA-
armatur/Stängventiler</span>
Any ideas why these attributes can't render?
The example with just the xpage tag is correctly generated but the problem is when the spabn is in the v-for loop
Edited m surrounding codeas the problem is when VUE.js attahces and runs for loop
This
<xp:span
id="clickSpan">
{{row.name }}
<xp:this.attrs>
<xp:attr
name="v-on:click"
value="alert('ok')"
rendered="true" />
</xp:this.attrs>
</xp:span>
renders
<span id="view:_id1:clickSpan" v-on:click="alert('ok')">{{row.name }}</span>
So, it works.
I guess you have a syntax error in source panel and your changes don't take effect yet.

i'm using axios to get data from api and store in an array after mounting then run a search query in the array later on, but it's not working unless i click on Root element in browsers Vue developer tools, after i click on vue Root element from vue dev tool everything works fine.Here is my code..
<script type="module">
const vueApp = new Vue({
el: "#pos",
data: {
searchTerm: "",
allProducts: [],
selectedProducts: [],
suggestions: []
},
mounted: function (){
axios.get("api/products").then( res => this.allProducts = res.data );
},
methods: {
select(item){
this.selectedProducts.push(item);
this.suggestions = [];
}
},
computed:{
matches(){
if(!this.searchTerm) return;
this.suggestions = this.allProducts.filter(sP=>(sP.prod_name).includes(this.searchTerm));
}
}
});
</script>
//HTML below------------------
<div id="pos">
<input type="text" v-model="searchTerm">
<ul v-for="match in suggestions">
<li #click="select(match)">
{{match.prod_name}}
</li>
</ul>
<table>
<tr v-for="(product,i) in selectedProducts">
<td>#{{product.prod_name}}</td>
</tr>
</table>
</div>
const vueApp = new Vue({
el: "#pos",
data: {
searchTerm: "",
allProducts: [],
selectedProducts: [],
suggestions: []
},
mounted: function() {
axios.get("api/products").then(res => this.allProducts = res.data);
},
methods: {
select(item) {
this.selectedProducts.push(item);
this.suggestions = [];
}
},
computed: {
matches() {
if (!this.searchTerm) return;
this.suggestions = this.allProducts.filter(sP => (sP.prod_name).includes(this.searchTerm));
}
}
});
<div id="pos">
<input type="text" v-model="searchTerm">
<ul v-for="match in suggestions">
<li #click="select(match)">
{{match.prod_name}}
</li>
</ul>
</div>
As I mentioned in the comments on your question, this is an error I cannot seem to understand how you are getting. I sense there is information that we are not being presented with.
As such, here is a quick "working" example of fetching items from the mounted lifecycle hook in a component. Note: If you are creating the component via a Single-File Component (.vue files) then don't worry too much about the declaration, pay attention only to the data and mounted methods.
const App = Vue.component('App', {
template: `<div>
<input v-model="searchTerm" type="search">
{{items.length}} results fetched
</div>`,
data() {
return {
searchTerm: '',
items: []
}
},
mounted() {
//Timeout used to mimic axios query
setTimeout(()=> this.items= [1,2,3,4], 1000)
}
});
const app = new App({
el: '#app'
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">Placeholder</div>
Edit
The code you have given us after your update seems to be working just fine. See the below snippet.
I noticed you are looping over suggestions but that value is never updated anywhere in your given code.
const vueApp = new Vue({
el: "#pos",
data: {
searchTerm: "",
allProducts: [],
selectedProducts: [],
suggestions: []
},
mounted: function() {
setTimeout(() => this.allProducts = [1,2,3,4,5], 1000);
},
methods: {
select(item) {
this.selectedProducts.push(item);
this.suggestions = [];
}
},
computed: {
matches() {
if (!this.searchTerm) return;
this.suggestions = this.allProducts.filter(sP => (sP.prod_name).includes(this.searchTerm));
}
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="pos">
<input type="text" v-model="searchTerm">
<ul v-for="match in suggestions">
<li #click="select(match)">
{{match.prod_name}}
</li>
</ul>
{{allProducts.length}} results loaded
</div>
mounted: function(){
var _self = this;
axios.get("api/products").then( res => _self.allProducts = res.data );
}
Im fetching a feed with fetch, but somehow my vue app does not render it i have tried diffrent things but nothing seems to work for me.
<section id="vue-instagram" class="instagram">
<div class="instagram__col" v-for="item in feed">
<div class="instagram__col__picturebox">
<img v-if="item.media_url.indexOf('.mp4') == -1" v-bind:src="item.media_url"/>
<video v-if="item.media_url.indexOf('.mp4') > 0" loop preload muted controls style="width:100%;">
<source v-bind:src="item.media_url" />
</video>
</div>
<div class="instagram__col__description">
<div class="instagram__col__descroption--icon">
<img src="images/insta.png"/>
</div>
<div class="instagram__col__descroption--text">
{{item.caption.substring(0,90)}}...
<div class="hashtags bold-text">
{{item.caption.substring(item.caption.indexOf('#'), item.caption.length).split(' ').slice(0,5).join(' ')}}
</div>
</div>
</div>
</div>
</section>
var app = new Vue({
el: '#vue-instagram',
data:() => ({
loading: false,
feed: [],
}),
}, created: async () => {
var response = await fetch("URL_TOSERVER", {
method: "POST",
});
var {data} = await response.json();
this.feed = data;
console.log(data);
});
If I call this.feed in chrome it displays the data but if I drill into app.data its empty.
The solution was to extract the call as a method
new Vue({
el: '#vue-instagram',
data: {
loading: false,
feed: [],
},
created: function() {
this.fetchData();
},
methods: {
fetchData: function(){
var self = this;
fetch("http://727.dk.web81.curanetserver.dk/umbraco/api/instagram/index", {
method:"POST"
}).then(function(response){
return response.json();
}).then(function(data){
self.feed = data.data;
});
}
},
computed: {
posts: function() {
return this.feed;
}
}
});
I have editable element updated by component method, but i have also json import and i want to update element my parent method. I can update model, but editable element doesn´t bind it. If i insert content to component template, it will bind updated model, but then i can´t really edit it.
Here´s my example: https://jsfiddle.net/kuwf9auc/1/
Vue.component('editable', {
template: '<div contenteditable="true" #input="update"></div>', /* if i insert {{content}} into this div, it wil update, but editing behave weird */
props: ['content'],
mounted: function () {
this.$el.innerText = this.content;
},
methods: {
update: function (event) {
console.log(this.content);
console.log(event.target.innerText);
this.$emit('update', event.target.innerText);
}
}
})
var app = new Vue({
el: '#myapp',
data: {
herobanner: {
headline: 'I can be edited by typing, but not updated with JSON upload.'
}
},
methods: {
uploadJSON: function (event) {
var input = event.target;
input.src = URL.createObjectURL(event.target.files[0]);
var data = input.src;
$.get(data, function(data) {
importdata = $.parseJSON(data);
this.$data.herobanner = importdata.herobanner;
}.bind(this));
}
}
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.4.2/vue.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<main id="myapp" class="container-fluid">
<input type="file" id="file" name="file" #change="uploadJSON" style="display: none; width: 1px; height: 1px"/>
<a href="" onclick="document.getElementById('file').click(); return false" title="Import settings from JSON file">
upload JSON
</a>
<h1>
<editable :content="herobanner.headline" #update="herobanner.headline = $event"></editable>
</h1>
Real value of model:
<br>
<h2>{{herobanner.headline}}</h2>
</main>
Working example:
Vue.component('editable', {
template: `
<div contenteditable="true" #blur="emitChange">
{{ content }}
</div>
`,
props: ['content'],
methods: {
emitChange (ev) {
this.$emit('update', ev.target.textContent)
}
}
})
new Vue({
el: '#app',
data: {
herobanner: {
headline: 'Parent is updated on blur event, so click outside this text to update it.'
}
},
methods: {
async loadJson () {
var response = await fetch('https://swapi.co/api/people/1')
var hero = await response.json()
this.herobanner.headline = hero.name
},
updateHeadline (content) {
this.herobanner.headline = content
}
}
})
<main id="app">
<button #click="loadJson">Load JSON data</button>
<h1>
<editable
:content="herobanner.headline"
v-on:update="updateHeadline"

<h2>{{herobanner.headline}}</h2>
</main>

Template part :
`<div class="col-sm-6" >
<ul class="list-group" id="pos">
<li class="list-group-item" v-for="(itm, index) in items">
<strong>{{index}} : {{ itm.sub }}</strong> - {{ itm.price }}
</li>
</ul>
</div>`
Script part :
new Vue({
el: '#pos',
http: {
root: '/vuetest',
headers: {
Authorization: 'Basic YXBpOnBhc3N3b3Jk'
}
},
data: {
items: []
},
created:function () {
this.$http.get('index.php').then(function(resp,status,request){
this.items = resp.data;
console.log(this.items); // got data but not displayed in browser
}.bind(this));
}
});
My Source files are from cdnjs.cloudeflare.com:
vue.js (2.1.4)
vue-resource.js (1.0.3).
Well, this isn't that...
created:function () {
this.$http.get('index.php').then(function(resp,status,request){
this.items = resp.data; // this is referring to the current function, and not to vue's scope.
console.log(this.items); // got data but not displayed in browser
}.bind(this));
}
So the correct use is:
created:function () {
var self = this
this.$http.get('index.php').then(function (resp,status,request) {
self.items = resp.data;
console.log(this.items);
});
}
As MU commented above, better you to use Arrows functions, so the "this" will have the scope you want.
mounted () {
}
Then you can access all your Data properties normally with "this".
I'm struggling to understand how to make my component reactive. At the moment the button is rendered correctly but once the create/delete event happens, the template does not change. Any tips on how to update the component after the event has taken place?
new Vue({
el: '#app'
});
Vue.component('favourite-button', {
props: ['id', 'favourites'],
template: '<input class="hidden" type="input" name="_method" value="{{ id }}" v-model="form.listings_id"></input><button v-if="isFavourite == true" class="favourited" #click="delete(favourite)" :disabled="form.busy"><i class="fa fa-heart" aria-hidden="true"></i><button class="not-favourited" v-else #click="create(favourite)" :disabled="form.busy"><i class="fa fa-heart" aria-hidden="true"></i></button><pre>{{ isFavourite == true }}</pre>',
data: function() {
return {
form: new SparkForm({
listings_id: ''
}),
};
},
created() {
this.getFavourites();
},
computed: {
isFavourite: function() {
for (var i = 0; this.favourites.length; i++)
{
if (this.favourites[i].listings_id == this.id) {
return true;
}
}
},
},
methods: {
getFavourites() {
this.$http.get('/api/favourites')
.then(response => {
this.favourites = response.data;
});
},
create() {
Spark.post('/api/favourite', this.form)
.then(favourite => {
this.favourite.push(favourite);
this.form.id = '';
});
},
delete(favourite) {
this.$http.delete('/api/favourite/' + this.id);
this.form.id = '';
}
}
});
Vue.component('listings', {
template: '#listing-template',
data: function() {
return {
listings: [], favourites: [],
};
},
created() {
this.getListings();
},
methods: {
getListings() {
this.$http.get('/api/listings')
.then(response => {
this.listings = response.data;
});
}
}
});
Vue expects HTML template markups to be perfect. Otherwise you will run into multiple issues.
I just inspected your template and found an issue - the first <button> element does not close.
Here is the updated version of your code:
Vue.component('favourite-button', {
props: ['id', 'favourites'],
template: `
<input class="hidden" type="input" name="_method" value="{{ id }}" v-model="form.listings_id"></input>
<button v-if="isFavourite == true" class="favourited" #click="delete(favourite)" :disabled="form.busy">
<i class="fa fa-heart" aria-hidden="true"></i>
</button> <!-- This is missing in your version -->
<button class="not-favourited" v-else #click="create(favourite)" :disabled="form.busy">
<i class="fa fa-heart" aria-hidden="true"></i>
</button>
<pre>{{ isFavourite == true }}</pre>
`,
...
Note the comment on 7th line above, the closing </button> tag is not present in your template.
As a side note, if you do not want to type back-slash at the end of every line to make multi-line template strings, you can use back-ticks as shown in my code example above. This will help you avoid markup errors leading to Vue component issues and many hours of debugging.
Another reference: Check out "Multi-line Strings" in this page: https://developers.google.com/web/updates/2015/01/ES6-Template-Strings
Relevant lines (copied from above page):
Any whitespace inside of the backtick syntax will also be considered part of the string.
console.log(`string text line 1
string text line 2`);
EDIT: Found a possible bug in code
Here is another issue in your create method of favourite-button component:
methods: {
// ...
create() {
Spark.post('/api/favourite', this.form)
.then(favourite => {
this.favourite.push(favourite); // Note: This is the problem area
this.form.id = '';
});
},
//...
}
Your success handler refers to this.favourite.push(...). You do not have this.favourite in data or props of your component. Shouldn't it be this.favourites?
