How to copy a codepen.io example into a .vue - vue.js

I found a codepen.io example (https://codepen.io/srees/pen/pgVLbm) I want to play around with in the context of a .vue app I'm working on, and I need some help transferring the <script> section over.
I copied the HTML chunk into a <template> and the CSS into a <style>. I've confirmed the .vue file works within the broader context (content loads when the <script> is commented out. I also placed <script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js" /> immediately before my <script> to resolve the $ not defined error I was getting. Is there something I need to import into App.vue or into this particular .vue file? When I leave <script> uncommented, I simply get a blank page loaded.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js" />
<script>
var hidWidth;
var scrollBarWidths = 40;
...

you could define a method like this:
methods: {
renderStuff: function () {
var hidWidth;
var scrollBarWidths = 40;
var widthOfList = function(){
var itemsWidth = 0;
$('.list li').each(function(){
var itemWidth = $(this).outerWidth();
itemsWidth+=itemWidth;
});
return itemsWidth;
};
var widthOfHidden = function(){
return (($('.wrapper').outerWidth())-widthOfList()-getLeftPosi())-
scrollBarWidths;
};
var getLeftPosi = function(){
return $('.list').position().left;
};
var reAdjust = function(){
if (($('.wrapper').outerWidth()) < widthOfList()) {
$('.scroller-right').show();
}
else {
$('.scroller-right').hide();
}
if (getLeftPosi()<0) {
$('.scroller-left').show();
}
else {
$('.item').animate({left:"-="+getLeftPosi()+"px"},'slow');
$('.scroller-left').hide();
}
}
reAdjust();
$(window).on('resize',function(e){
reAdjust();
});
$('.scroller-right').click(function() {
$('.scroller-left').fadeIn('slow');
$('.scroller-right').fadeOut('slow');
$('.list').animate({left:"+="+widthOfHidden()+"px"},'slow',function(){
});
});
$('.scroller-left').click(function() {
$('.scroller-right').fadeIn('slow');
$('.scroller-left').fadeOut('slow');
$('.list').animate({left:"-="+getLeftPosi()+"px"},'slow',function(){
});
});
}
}
and run the method on mount like this:
mounted() {
this.renderStuff();
}
Side note, var is not ideal in this day and age. Recommend converting these to let.

VueJS Leaflet 'moveend' fires multiple times

Ask for help from the community. For two weeks I can not overcome the problem with repeated firing of 'mooveend' in the project. I have tried all the advice given here. Here's what I've read and researched already, but it didn't work for me.
This is one of the tips:
moveend event fired many times when page is load with Leaflet
<template>
<div id="map"></div>
</template>
<script>
export default {
name: "ObjectMapView",
props: ['coordinate'],
data: function () {
return {
map: null,
addressPoints: null,
markers: null,
}
},
mounted: function() {
this.initializedMap();
},
watch: {
coordinate: function (val) {
this.run();
}
},
methods: {
initializedMap: function () {
this.map = L.map('map').setView([52.5073390000,5.4742833000], 13);
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors'
}).addTo(this.map);
this.markers = L.markerClusterGroup();
},
run: function () {
var map = this.map;
var markers = this.markers;
var getAllObjects = this.coordinate;
var getBoundsMarkers;
//Clearing Layers When Switching a Filter
markers.clearLayers();
this.addressPoints = getAllObjects.map(function (latlng){
return [latlng.latitude, latlng.longitude, latlng.zip, latlng.object_id, latlng.archived];
});
map.addLayer(markers);
//We give to the map only those coordinates that are in the zone of visibility of the map during the first
getBoundsMarkers = getAllObjects.filter((coord) => {
if(!coord.latitude && !coord.longitude){
return false;
}
return map.getBounds().contains(L.latLng(coord.latitude, coord.longitude));
});
/*
Responds to changing the boundaries of the map visibility zone and
transmits a list of coordinates that are in the visibility zone
*/
console.log('getAllObjects_1', getAllObjects);
map.on('moveend', function() {
console.log('moveend');
console.log('getAllObjects_2', getAllObjects);
getBoundsMarkers = getAllObjects.filter((coord) => {
if(!coord.latitude && !coord.longitude){
return false;
}
return map.getBounds().contains(L.latLng(coord.latitude, coord.longitude));
});
eventHub.$emit('sendMarkers', getBoundsMarkers);
});
// In the loop, we iterate over the coordinates and give them to the map
for (var i = 0; i < this.addressPoints.length; i++) {
var a = this.addressPoints[i];
var title = '' + a[2] + ''; //bubble
var marker = L.marker(new L.LatLng(a[0], a[1]), {
title: title
});
marker.bindPopup(title);
markers.addLayer(marker);
}
eventHub.$emit('sendMarkers', getBoundsMarkers);
}
}
}
</script>
<style scoped>
#map {
width: 97%;
height: 100%;
}
</style>
I figured it out myself.
The 'zoomend' and 'dragend' option didn't work for me. I searched a lot for a suitable option and realized that the "moveend" event fires several times because this event is created every time you move the map. Therefore it is necessary to stop this event. I got out of the situation in this way. Immediately after the map was initialized, I wrote:
map.off('moveend');
and for me it worked. Now it works fine. I will be very happy if this is useful to someone.

Using dropzone.js in vue, calling function with image file name

I'm having a hard time getting anything to work with this the way I need it, but I have a working dropzone instance in my Vue project.
I can upload the image and call functions within the dropzone code, however, I need to call a function directly from the form in the html in order to send the 'card' object.
All I need to do is call a function when a file is added through the dropzone form, with the filename.
My code:
<div class="uk-width-3-10">
<form v-on:change="imageChange(card)" method="post" action="{{url('product/parts/upload/store')}}" enctype="multipart/form-data"
class="dropzone" v-bind:id="'dropzone-'+i">
</form>
</div>
...
imageChange(Card){
console.log('working');
},
addCard(){
Vue.nextTick(function () {
new Dropzone("#dropzone-"+cardIndex, {
maxFilesize: 12,
renameFile: function (file) {
var dt = new Date();
var time = dt.getTime();
return time + file.name;
},
acceptedFiles: ".jpeg,.jpg,.png,.gif",
addRemoveLinks: true,
timeout: 50000,
removedfile: function (file) {
console.log(file.upload.filename);
var name = file.upload.filename;
var fileRef;
return (fileRef = file.previewElement) != null ?
fileRef.parentNode.removeChild(file.previewElement) : void 0;
},
init: function() {
this.on("addedfile",
function(file) {
instance.imageZoneNames.push({name: file.upload.filename});
console.log(file);
console.log(instance.imageZoneNames);
});
}
});
});
}
Dropzone has many events, You used removedfile() event! there is another event called addedfile() and executes when a file is added to the dropzone list
imageChange(card) {
console.log(card)
},
addCard() {
Vue.nextTick(() => {
new Dropzone('#dropzone-` + cardIndex, {
addedfile(file) {
this.imageChange(file);
}
}
}
}

Getting reactivity from watch in Vue.js

Trying to make a component in Vue.js, which first shows image via thumbnail, loading full image in background, and when loaded, show full image.
The thing which does not work, component does not react on change of showThumb flag in watch section. What is wrong?
Vue.component('page-image',
{
props: ['data'],
template:
'<img v-if="showThumb == true" v-bind:src="thumbSrc"></img>'+
'<img v-else v-bind:src="fullSrc"></img>',
data: function()
{
return { thumbSrc: '', fullSrc: '', showThumb: true };
},
watch:
{
data: function()
{
this.thumbSrc = data.thumbImg.url;
this.fullSrc = data.fullImg.url;
this.showThumb = true;
var imgElement = new Image();
imgElement.src = this.fullSrc;
imgElement.onload = (function()
{
this.showThumb = false; // <<-- this part is broken
} );
}
}
} );
Note: there is a reason why I do it via 2 img tags - this example is simplified.
Your onload callback will have a different scope than the surrounding watch function, so you cannot set your data property like this. Change it to an arrow function to keep scope:
imgElement.onload = () =>
{
this.showThumb = false;
};

Unable to print output to the console in dojo

I'm a beginner in dojo, and I'm trying to print the output to console using dojo code. But I don't what's the problem in the following code, and how can I print the output to the console?
<html>
<head>
<script type = "text/javascript" src = "dojo/dojo.js" data-dojo-config = "async: true, isDebug : true" >
</script>
</head>
<body>
<h1 id = "greeting">Hello</h1>
<script>
define(["dojo/dom"],function(dom) {
var Twitter = declare(null, {username:"defaultusername",
say :function(msg)
{
console.log("Hello "+msg);
}
});
var myInstance = new Twitter();
myInstance.say("Dojo");
});
</script>
</body>
</html>
Use require instead of define:
<script>
require(["dojo/dom", "dojo/_base/declare"], function(dom, declare) {
var Twitter = declare(null, {
username: "defaultusername",
say :function(msg) {
console.log("Hello "+msg);
}
});
var myInstance = new Twitter();
myInstance.say("Dojo");
});
</script>
Console works, but your code inside callback function in declare is not being executed until you require it.
You cannot define in inline script code, that is meant to be a class define, put in the topmost line of a class-file, meaning define maps the filename to the returned value of its function.
This means, if you have
dojo_toolkit /
dojo/
dijit/
dojox/
libs/
myWidgets/
foo.js
And foo.js reads
define(["dijit._Widget"], function(adijit) {
return declare("libs.myWidgets.foo", [adijit], function() {
say: function(msg) { console.log(msg); }
});
});
Then a new module is registered, called libs / myWidgets / foo. You should make sure that the returned declare's declaredClass inside each define matches the file hierachy.
That being said, reason why define does not work for you is the explaination above. It is inline and has no src to guess the declaredClass name from. Rewrite your code to define("aTwitterLogger", [":
define("aTwitterLogger", ["dojo/_base/declare", "dojo/dom"],function(declare, dom) {
var Twitter = declare(null, {
username:"defaultusername",
say :function(msg)
{
console.log("Hello "+msg);
}
});
var myInstance = new Twitter();
myInstance.say("Dojo");
});
