i open a testroom videoconference with chrome https://meet.jit.si/testroom and tried the following script in another browsertab, but no video, i dont know what to put into the body section for displaying the room?
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script src='https://meet.jit.si/external_api.js'></script>
</head>
<body>
<div id="app1">
{{ message }}
</div>
<script>
var vm1 = new Vue({
el: '#app1',
data: {
message: 'Hello Jitsi with Vue!'
}
})
const domain = 'meet.jit.si';
const options = {
roomName: 'testroom',
width: 700,
height: 700,
parentNode: document.querySelector('#meet')
};
const api = new JitsiMeetExternalAPI(domain, options);
</script>
</body>
<html>
this script works now, be sure to use chrome as browser
the doco of the options you find here
https://github.com/jitsi/jitsi-meet/blob/master/doc/api.md
you can also build up your own videoconfernce server
api.html
<html>
<head>
<script src="https://meet.jit.si/external_api.js"></script>
</head>
<body>
<div id="meet"></div>
<script>
var domain = 'meet.jit.si';
var options = {
roomName: 'testroom',
width: 500,
height: 500,
interfaceConfigOverwrite: { filmStripOnly: false },
parentNode: document.querySelector('#meet')
};
var api = new JitsiMeetExternalAPI(domain, options);
</script>
</body>
</html>
I believe you missed a needed element: 'meet'
<div id="app1">
{{ message }}
<div id="meet"></div> <!-- missing -->
</div>
It's used by JitsiMeetExternalAPI:
parentNode: document.querySelector('#meet')

im learnign VUE JS and I dont understand this behavior (strange for me).
I want to get list of people in table via Vue component.
Html tag table is under the list.
Documentation says: Every compoment must have one single root, ok I can wrap each tr with tbody but it doesnt solve this problem.
How to solve it?

I have found a tool called XLSX to JSON on github, which has been made using vuejs/sheetjs. git repo, This tool is available online via an interface - but recently it seems to have broken and I cant download my converted json file.
Therefore my intention was to clone the repo, and change some bits around to fix it (just console json file instead of DL).
I haven't used Vue js before. After looking through the index and the origins of the functions I saw that the whole page seems to be reliant on this app.vue file. However - when editing the values and reloading the webpage - theres no change what so ever!
App.vue:
<template>
<div class="col">
<div class="row">
<div id="dropZone" v-on:drop.prevent="parseXLSX($event)" v-on:dragend="cleanup" ondragenter="event.preventDefault();" ondragover="event.preventDefault(); event.dataTransfer.dropEffect='copy'" class="col drop-box">
<h2 class="text-center"> Drag your xlsx file here.</h2>
</div>
</div>
<div class="row">
<input type='file' id='inputFile' v-on:change="parseXLSX($event.target.files)">
<div v-if="hasDownload">
<a id="download"> Download Localalization JSON </a>
</div>
</div>
<div class="row">
<div class="col json-box">
<h2 class="text-center"> JSON Output</h2>
<pre id="output"> </pre>
</div>
</div>
<xlsx-footer></xlsx-footer>
</div>
</template>
<script>
import Footer from './components/footer.vue';
export default {
data() {

hasDownload: false,

parseXLSX(event) {
const XLSX = window.XLSX;
let file = this.getFile(event);
let workBook = null;
let jsonData = null;
if(file !== null) {
const reader = new FileReader();
const rABS = true;
reader.onload = (event) => {
// I WANT TO do edits but nothing seems to work
//console logs not working etc...
const data = event.target.result;
if(rABS) {
workBook = XLSX.read(data, {type: 'binary'});
jsonData = workBook.SheetNames.reduce((initial, name) => {
const sheet = workBook.Sheets[name];
initial[name] = XLSX.utils.sheet_to_json(sheet);
return initial;
}, {});
const dataString = JSON.stringify(jsonData, 2, 2);
document.getElementById('output').innerHTML = dataString.slice(0, 300).concat("...");
this.setDownload(dataString);
}
}

All I want to do is edit the functions in the app.vue file!
Any help would be great, cheers!
Try to modify the package.json file by adding "prod":"webpack" in the "scripts" brackets. Running npm run prod should recreate your bundle.js file after .vue files modification using the webpack.config.js provided.
Also you could use script test using npm run test which launch webpack-dev-server and enable hot reload which is more convinient for dev purpose.
When you make change in any vue js file you have run npm run prod and you have to either upload the whole project in the server or upload the public folder in the server
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.

The uppercase filter has been removed in Vue.js 2.
https://v2.vuejs.org/v2/guide/migration.html#Built-In-Text-Filters-removed
You can simply use:
{{ text.toUpperCase() }}
As far as the structure of your code goes, something like this is probably better off in a method:
close: function() {
this.alertType= null;
this.title= null;
this.message= null;
this.showAlert= false;
}
Since you are duplicating it twice but just with different values.
I am a fresher.I try to use scope slot and directive to create a list sample ,the code follow:

Vue.directive("selectall",{

var arg = binding.arg,
value = binding.value;
console.log(arg,value);
$(el).on('change',function(){

}
});
Vue.component("list",{

var app = new Vue({

and here are essential fragment:

+"</list>"
but the result is like this:
enter image description here
I find out that the slot return to NaN,so I am so confused.Can you help me find the keys point to resolve this bug?Thank you!

I'm learning about google maps API, and I am just trying to get a simple address search to work, what am I missing? I've seen similar posts, but can't find what isn't right, might need some fresh eyes.
Varaibles map and geocoder are not visible outside of initialize() function. If you open console there is error written:
ReferenceError: geocoder is not defined
They should be made global like:
var map,
geocoder;
function initialize() {
geocoder = new google.maps.Geocoder();
var mapOptions = { center: new google.maps.LatLng(40.5, -75.5), zoom: 8 };
map = new google.maps.Map(document.getElementById("map-canvas"), mapOptions);
}
Additionaly, div tag is not self-closing.
<div id="map-canvas"/>
should be changed to
<div id="map-canvas"></div>
