i am quite new in vuejs, so cant find out what am i doing wrong. This is my script part for a vue component:
<script>
export default {
name: 'product-main-info',
components: {
vueDropzone: vue2Dropzone
},
props: {
propId: String,
},
data() {
return {

thumbnailWidth: 150,
maxFilesize: 2.0,
addRemoveLinks: true,
acceptedFiles: ".png,.jpg,.gif,.bmp,.jpeg",
headers: { "X-CSRF-Token": document.head.querySelector('meta[name="csrf-token"]').content },
params: { id: this.propId },
init: function() {
var self = this;
self.on("success", function (file) {
this.$http.get('/getProductImages/' + this.propId)
.then(function(response) {
this.images = response.data;
});
});
}
}
}
},
methods: {
},
created() {
this.$http.get('/getProductImages/' + this.propId)
.then(function(response) {
console.log(response.data);
this.images = response.data;
});
}
}
</script>
I am trying to get new refreshed data after successful image upload, but all i get is:
app.js:16014 Uncaught TypeError: Cannot read property 'get' of undefined
All i need is to refresh my data, but i cant find out how to do this in a right way. Help if possible

Trying to use Uppy JS lib to upload file throug Laravel. Setted up simple upload form with there params:
const options = {
endpoint: '/parts/image-upload',
headers: {
'X-XSRF-TOKEN': $('meta[name="csrf-token"]').attr('content'),
},
};
uppyDashboard.use(XHRUpload, options);
And on the backend I'm getting
Illuminate\Contracts\Encryption\DecryptException: The payload is invalid. in file /Users/rd/Projects/xxx/vendor/laravel/framework/src/Illuminate/Encryption/Encrypter.php on line 195
It's like Laravel trying to decrypt something what is already decrypted, anyway I'm in dead end.
You can this code
var uppy = new Uppy.Core({
// debug: (...args) => console.debug(`[Uppy] [${getTimeStamp()}]`, ...args),
// warn: (...args) => console.warn(`[Uppy] [${getTimeStamp()}]`, ...args),
// error: (...args) => console.error(`[Uppy] [${getTimeStamp()}]`, ...args),
autoProceed: true,
restrictions: {
maxFileSize: 2000000,
maxNumberOfFiles: 10,
minNumberOfFiles: 1,
allowedFileTypes: ['image/*']
}
});
uppy.use(Uppy.Dashboard, {
target: ".UppyDragDrop",
inline: true,
showLinkToFileUploadResult: false,
showProgressDetails: true,
hideCancelButton: true,
hidePauseResumeButton: true,
hideUploadButton: true,
proudlyDisplayPoweredByUppy: false,
locale: {} });
Here's how I implemented it
<script type="text/javascript">
$(document).ready(function() {
$('[id*=drag-drop-area]').each(function(){
var listing_id = $(this).attr('class');
var uppy = new Uppy.Core({
allowMultipleUploadBatches: true,
restrictions: {
maxFileSize: 100000000,
// maxNumberOfFiles: 8,
minNumberOfFiles: 1,
allowedFileTypes: ['image/*', '.jpg', '.jpeg', '.png']
}
})
.use(Uppy.Dashboard, {
inline: true,
target: "#"+$(this).attr('id')+""
})
.use(Uppy.XHRUpload, {
endpoint: 'upload',
formData: true,
bundle: true,
headers: {
'X-CSRF-Token': " {{ csrf_token() }} "
},
});
uppy.on('upload-success', (file, response) => {
response.body.data.forEach(function (item, index) {
console.log(listing_id);
var token =
$('meta[name="csrftoken"]').attr('content');
$.ajax({
url: 'attach',
type: 'POST',
data: { '_token' : token, item, listing_id},
success: function(response)
{
console.log('Updated');
},
error:function (e) {
console.log(e);
}
});
});
window.location.reload();
});
});
});
</script>
You create the endpoint which is the route name and attach at
endpoint: ""
Then you return a response which you grab and do whatever on the last section.
uppy.on('upload-success', (file, response) => {
response.body.data.forEach(function (item, index) {
console.log(listing_id);
var token =
$('meta[name="csrftoken"]').attr('content');
$.ajax({
url: 'attach',
type: 'POST',
data: { '_token' : token, item, listing_id},
success: function(response)
{
console.log('Updated');
},
error:function (e) {
console.log(e);
}
});
});
window.location.reload();
});
I hope this helps
The Axios response.data is okay. But when I use the markers variable in rendering the markers is undefined. I am a newbie and badly need your help for our project.
I am trying to render the markers from the link described in the code, but some I placed the axios request in the created, and in the mounted is the rendering of the leaflet map.
Screenshot of the code
<script>
/** Script Vue JS **/
new Vue({
el: '#view-map',
data: {
map,
map_link:'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
markerOption: {
clickable: true,
draggable: false
},
mapOptions: {
center: [7.3087, 125.6841],
zoom:8
},
markers:[], //[{"image":"GMS-4-0112018-467_1527086274.jpg","derivation_code":"GMS-4-0112018-467","sample_description":"test 1 test is a test that test will be tested in test","latitude":"6.428152","longitude":"125.317857"},{"image":"GMS-1-0112018-963_1527134301.jpg","derivation_code":"GMS-1-0112018-963","sample_description":"nalaya lang","latitude":"7.311647","longitude":"125.636461"}],
selectedSample: [],
},
methods: {
getMarkers: function (){
axios.get('http://127.0.0.1:8000/marker').then(response => {
this.markers = response.data;
}).catch(error =>( console.log(error) ));
},
renderMarker: function(){
for ( i = 0; i < this.markers.length; i++){
console.log(this.markers[i]);
var marker = new L.Marker([this.markers[i].latitude, this.markers[i].longitude], this.markerOption);
marker.addTo(this.map);
marker.bindPopup(`
<h6 class="display-6">${this.markers[i].derivation_code}</h6>
<img src="storage/images/${this.markers[i].image}" style="height:100%;width:100%">
`);
}
},
markerClicked: function(mrkr_data){
this.selectedSample = mrkr_data.derivation_code;
console.log(this.selectedSample);
}
},
created: function(){
this.getMarkers();
},
mounted: function(){
this.map = new L.map('map', this.mapOptions);
this.map.addLayer(new L.TileLayer(this.map_link));
console.log(this.markers);
this.renderMarker();
}
});
</script>
I solved my problem. I treated the fetching of data in Axios get property as a Synchronous but it is an Asynchronous. Base in my previous code, I accessed the data when it is not updated so the value is blank.
/** Script Vue JS **/
new Vue({
el: '#view-map',
data: {
map,
map_link:'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
markerOption: {
clickable: true,
draggable: false
},
mapOptions: {
center: [7.3087, 125.6841],
zoom:8
},
markers:[], //[{"image":"GMS-4-0112018-467_1527086274.jpg","derivation_code":"GMS-4-0112018-467","sample_description":"test 1 test is a test that test will be tested in test","latitude":"6.428152","longitude":"125.317857"},{"image":"GMS-1-0112018-963_1527134301.jpg","derivation_code":"GMS-1-0112018-963","sample_description":"nalaya lang","latitude":"7.311647","longitude":"125.636461"}],
selectedSample: [],
},
created: function(){
this.getMarkers();
},
mounted: function(){
this.map = new L.map('map', this.mapOptions);
this.map.addLayer(new L.TileLayer(this.map_link));
},
watch: {
markers: function(){
this.renderMarker();
}
},
methods: {
getMarkers: function (){
axios.get('http://127.0.0.1:8000/marker').then(response => {
this.markers = response.data;
console.log(this.markers);
}).catch(error =>( console.log(error) ));
console.log(this.markers);
},
renderMarker: function(){
for ( i = 0; i < this.markers.length; i++){
console.log(this.markers[i]);
var marker = new L.Marker([this.markers[i].latitude, this.markers[i].longitude], this.markerOption);
marker.addTo(this.map);
marker.bindPopup(`
<h6 class="display-6">${this.markers[i].derivation_code}</h6>
<img src="storage/images/${this.markers[i].image}" style="height:100%;width:100%">
`);
}
},
markerClicked: function(mrkr_data){
this.selectedSample = mrkr_data.derivation_code;
console.log(this.selectedSample);
}
},
});
So here's my code
var portal = new Vue({
el: "#AnnounceController",
data: {
ann: {
id: '',
content: ''
},
announces: [],
success: false,
edit: false
},
methods: {
fetchAnnounce: function () {
axios.get('/api/announces')
.then(function (response) {
this.announces = response.data;
console.log(this.announces);
})
.catch(function (error) {
console.log(error);
});
}
},
computed: {},
mounted: function () {
console.log('mounted')
this.fetchAnnounce()
}
I have a GET request via axios to a laravel based api, when I look at the response from axios I do see my data, when I try to assign that data to the 'announces' from data, it doesn't work. Vue-devtools shows my data 'announces' attribute as empty, and the log for this.announces shows me my data, somehow like the data attribute for the vue instance and the this.announces are different.
fetchAnnounce: function () {
axios.get('/api/announces')
.then(function (response) {
this.announces = response.data;
console.log(this.announces);
}.bind(this))
.catch(function (error) {
console.log(error);
});
}
I've integrated DropzoneJs into a VueJs application im putting together. It's running great in both Chrome and Firefox but for some reason the app is very sad in safari. I'm getting the following error in Safari: Attempted to redefine property 'filesizeBase'.
My Vue Component Looks as Follows:
var Dropzone = require('../../vendor/dropzone.min.js');
module.exports = {
template: require('./views/files.html'),
props: ['files', 'is-complete'],
data: function()
{
return {
reverse: -1,
uploading: false,
token: document.querySelector('#token').getAttribute('value'),
project: document.querySelector('#project').getAttribute('value'),
}
},
methods: {
uploadFile: function(e)
{
e.preventDefault();
var self = this;
this.uploading = !this.uploading;
if(this.uploading)
{
var myDropzone = new Dropzone("form#mediaUpload", {
init: function() {
this.on("complete", function(file) {
setTimeout(function()
{
self.uploading = false;
}, 5000);
});
this.on("success", function(file, uploadedFile) {
self.files.push(uploadedFile);
});
},
paramName: "file",

}
},
deleteFile: function(file, index)
{
this.files.pop(index);
this.$nextTick(function()

this.$http.post('/upload/'+file.id+'/delete');
});
},
},

fileSize: require('./FileSize'),
humanTime: require('../Helpers/HumanTime'),
mimeType: require('../Helpers/MimeType'),
}
}
I need to setup my datasource to use localForage to manage my offline data storage.
The problem I'm having is that localForage is asynchronous by nature, only allowing us to use a callback or a promise to retrieve data.
This is how my code is set-up:
(function () {
'use strict';
var serviceId = 'employeeDataSource';
angular.module('app').factory(serviceId, function () {
var crudServiceBaseUrl = 'Data/Employees';
var dataSource = new kendo.data.DataSource({
type: "odata",
offlineStorage: {
getItem: function () {
localforage.getItem('employees-key').then(function (value) {
console.log(value);
return JSON.parse(value);
});
},
setItem: function (item) {
if (item.length > 0) {
localforage.setItem("employees-key", JSON.stringify(item));
}
}
},
transport: {
read: {
url: crudServiceBaseUrl + "/",
dataType: "json"
},
update: {
url: function (data) {
return crudServiceBaseUrl + "(guid'" + data.EmployeeId + "')";
}
},
create: {
url: crudServiceBaseUrl
},
destroy: {
url: function (data) {
return crudServiceBaseUrl + "(guid'" + data.EmployeeId + "')";
}
}
},
batch: false,
pageSize: 5,
serverPaging: true,
schema: {
data: function (data) {
return data.value;
},
total: function (data) {
return data['odata.count'];
},
model: {
id: "EmployeeId",
fields: {
EmployeeId: { editable: false, nullable: true },
Name: { validation: { required: true } },
Email: { validation: { required: true } },
IsManager: { type: "boolean" },
MaxHolidaysPerYear: { editable: false, type: "number", validation: { min: 0, required: true } },
HolidaysLeftThisYear: { type: "number", validation: { min: 0, required: true } }
}
}
},
error: function (e) {
if (e.xhr.responseText !== undefined) {
console.log(e.xhr.responseText);
}
}
});
dataSource.online(navigator.onLine);
$(window).on("offline", function () {
dataSource.online(false);
});
$(window).on("online", function () {
dataSource.online(true);
});
return dataSource;
});
})();
When off-line, the getItem gets called, then the setItem gets call as well with an empty array, hence the:
if (item.length > 0) {
localforage.setItem("employees-key", JSON.stringify(item));
}
When the promise finally returns the off-line data (with the correct values I expected), the Grid displays no results.
This behaviour is presumably because of the promise ?
I tried the same thing with sessionStorage and its worked perfectly... i.e.:
getItem: function () {
return JSON.parse(sessionStorage.getItem("employees-key"));
},
setItem: function (item) {
sessionStorage.setItem("employees-key", JSON.stringify(item));
}
What can I do to get around this?
Just got a heads-up from Telerik
There is an issue logged in their GitHub repo about the same problem.
