How can I test?
element.bind('change', function(evt) {
var files = evt.target.files;
if (!attrs.previewContainer) {
attrs.previewContainer = "preview";
var div = document.createElement("div");
var li = document.createElement("li");
li.appendChild(div);
li.id = attrs.previewContainer;
element.append(div);
}
if (typeof files !== "undefined") {
if (attrs.multiple) {
for (var i = 0, l = files.length; i < l; i++) {
loadMetadata(files[i], attrs).then(function(result) {
result.url = URL.createObjectURL(files[i]);
scope.metadata.push(result);
});
}
} else {
loadMetadata(files[0], attrs).then(function(result) {
result.url = URL.createObjectURL(files[0]);
scope.metadata = result;
});
}
}
});
The file HTML:
<input name='uploadVideo' type="file" metadata="uploadVideo"
preview-container="videoPreview" data-ng-model="uploadVideo.file">
I want to create a test file on a custom directive that deals in uploading a video and see a preview. So I would like to know how you create an event listening in angular:
Or similar
it('Test input file', inject(function() {
fakeFile = {
name: '/home/developer/mcd2/public/modules/uploads/store/videos/542e73cf054fbc3a1630d216/bear_movie.mp4'
};
var fileInput, evt;
fileInput = element.find('input').trigger('input');
evt = $.Event('change');
evt.target = {
files: [fakeFile]
};
angular.element(fileInput).triggerHandler(evt);
fileInput.trigger(evt);
expect(form.$modelValue.name).toBe(fakeFile.name);
expect(form.$valid).toBeTruthy();
}));

I have an issue I have a "chat" and when I add a new text in my infinite scroll container,
I go back to the top of the page, i'm not stuck to the bottom.
How can I maintain the page in the bottom of my page while people chat
my service
tabs.factory('chat', function ($http, $timeout, $q) {
return {
default: {
delay: 100
},
data: [],
dataScroll: [],
init: function (data) {
if (this.data.length == 0) {
for (var i = 0; i < data.length; i++) {
this.data[i] = data[i]
}
} else {
var tailleDataSaved = this.data.length
var dataAAjouter = data.slice(tailleDataSaved)
for (var i = 0; i < dataAAjouter.length; i++) {
this.data.push(dataAAjouter[i])
}
}
},
request: function (showAll) {
var self = this;
var deferred = $q.defer();
var index = this.dataScroll.length
var ndDataVisible = 7
var start = index;
var end = index + ndDataVisible - 1;
$timeout(function () {
if (!showAll) {
var item = []
if (start < end) {
for (var i = start; i < end; i++) {
console.log(start)
console.log(end)
console.log(self.data[i])
if (item = self.data[i]) {
self.dataScroll.push(item);
}
}
}
} else {
self.dataScroll = self.data
}
deferred.resolve(self.dataScroll);
}, 0);
return deferred.promise;
}
}
})
my js file
$scope.listChat= function () {
$scope.isActionLoaded = false;
$http.get(apiurl).then(function (response) {
chat.init(response.data)
$scope.isActionLoaded = true
})
}
$scope.listChatInfiniteScroll = function () {
$scope.isScrollDataLoaded = false
ticketListeActionScroll.request(false).then(function (response) {
$scope.actionsInfiniteScroll = response
$scope.isScrollDataLoaded = true
})
}
html file
<div ng-if="isActionLoaded" infinite-scroll='listChatInfiniteScroll ()' infinite-scroll-distance='1'>
<div ng-repeat="chat in actionsInfiniteScroll">
{{chat.text}}
</div>
</div>
Each time I add a new message it calls listChat
In this demo http://jsfiddle.net/mdz82oLn/ I have inserted videos (IDs) and images (png, jpeg, etc) which are also displayed by means of customized buttons. The demo works perfectly in the vision but reached the end of the last video it returns in loop when instead it should restart from the first video in the list, how to integrate this function?
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
const playerElement = document.querySelector('#player');
const imageElement = document.querySelector('#slide');
const videos = {
'RGpr3Y6Q-1M': 'http://nothingbutgeek.com/wp-content/uploads/2018/06/automata_16x9.png',
'btxdcqLOGuc': 'https://live.staticflickr.com/2400/2078946248_d063d5a563_b.jpg',
'CIx0a1vcYPc': 'https://i.ytimg.com/vi/CIx0a1vcYPc/maxresdefault.jpg',
};
const videoIds = Object.keys(videos);
function onYouTubeIframeAPIReady() {
function onPlayerReady({ target }) {
var playButton = document.getElementById("play-button");
playButton.addEventListener("click", function() {
target.playVideo();
});
var pauseButton = document.getElementById("pause-button");
pauseButton.addEventListener("click", function() {
target.pauseVideo();
});
var next = document.getElementById("next");
next.addEventListener("click", function() {
target.nextVideo();
});
var pre = document.getElementById("previous");
pre.addEventListener("click", function() {
target.previousVideo();
});
target.loadPlaylist({
playlist: videoIds
});
}
function onPlayerStateChange({ data, target }) {
switch(data) {
case YT.PlayerState.ENDED:
target.nextVideo();
break;
case YT.PlayerState.BUFFERING:
const playlist = target.getPlaylist();
const playlistIndex = target.getPlaylistIndex();
const currentId = playlist[playlistIndex];
const image = videos[currentId];
if (imageElement.src !== image) {
imageElement.src = image;
}
break;
}
}
const player = new YT.Player(playerElement, {
height: '405',
width: '720',
playerVars: {
controls: 1,
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
If I understand correctly you are stuck on last video and want to start the loop from 1 video:
In that case a change like this should work:
var next = document.getElementById("next");
next.addEventListener("click", function() {
target.nextVideo();
if(target.getPlaylistIndex() == videoIds.length -1){
target.loadPlaylist({
playlist: videoIds
});
}
});
Updated your Example
you can also update the switch case like this:
case YT.PlayerState.ENDED: {
if (target.getPlaylistIndex() == videoIds.length - 1) {
target.loadPlaylist({
playlist: videoIds
});
}
break;
}
I have drift's async script code in the index.html file of the react app.
<script>
"use strict";
!function () {
var t = window.driftt = window.drift = window.driftt || [];
if (!t.init) {
if (t.invoked) return void (window.console && console.error && console.error("Drift snippet included twice."));
t.invoked = !0, t.methods = ["identify", "config", "track", "reset", "debug", "show", "ping", "page", "hide", "off", "on"],
t.factory = function (e) {
return function () {
var n = Array.prototype.slice.call(arguments);
return n.unshift(e), t.push(n), t;
};
}, t.methods.forEach(function (e) {
t[e] = t.factory(e);
}), t.load = function (t) {
var e = 3e5, n = Math.ceil(new Date() / e) * e, o = document.createElement("script");
o.type = "text/javascript", o.async = !0, o.crossorigin = "anonymous", o.src = "https://js.driftt.com/include/" + n + "/" + t + ".js";
var i = document.getElementsByTagName("script")[0];
i.parentNode.insertBefore(o, i);
};
}
}();
drift.SNIPPET_VERSION = '0.3.1';
drift.load('----api----');
drift.on('ready', api => {
api.widget.hide();
})
</script>
The issue is, it is getting popped up in every page of the app whereas I want it only when I click a button(onClick)
The function to trigger onClick :
openDriftChat = () =>{
const { setDriftState } = this.props;
if (window.drift.api) {
//this needs to happen only once but currently happening on every page load
if (!this.props.driftInit) {
if (localStorage.token) {
var tokenBase64 = localStorage.token.split(".")[1];
var tokenBase64_1 = tokenBase64.replace("-", "+").replace("_", "/");
var token = JSON.parse(window.atob(tokenBase64_1));
window.drift.identify(token.email, {
email: token.email,
nickname: token.name
});
setDriftState(true);
}
}
window.drift.api.openChat();
}
}
I basically want it pop up only when I call the function.
Hello I had the same issue:
To hide the welcome message use the following css code
iframe#drift-widget.drift-widget-welcome-expanded-online {
display: none !important;
}
iframe#drift-widget.drift-widget-welcome-expanded-away {
display: none !important;
}
The welcome message will only be shown when your drift button. Some extra info:
To hide the drift button icon use the following js code
drift.on('ready', function (api) {
api.widget.hide()
drift.on('message', function (e) {
if (!e.data.sidebarOpen) {
api.widget.show()
}
})
drift.on('sidebarClose', function (e) {
if (e.data.widgetVisible) {
api.widget.hide()
}
})
})
To call for the sidebar from a specific button use the following
Javascript
(function () {
var DRIFT_CHAT_SELECTOR = '.drift-open-chat'
function ready(fn) {
if (document.readyState != 'loading') {
fn();
} else if (document.addEventListener) {
document.addEventListener('DOMContentLoaded', fn);
} else {
document.attachEvent('onreadystatechange', function () {
if (document.readyState != 'loading')
fn();
});
}
}
function forEachElement(selector, fn) {
var elements = document.querySelectorAll(selector);
for (var i = 0; i < elements.length; i++)
fn(elements[i], i);
}
function openSidebar(driftApi, event) {
event.preventDefault();
driftApi.sidebar.open();
return false;
}
ready(function () {
drift.on('ready', function (api) {
var handleClick = openSidebar.bind(this, api)
forEachElement(DRIFT_CHAT_SELECTOR, function (el) {
el.addEventListener('click', handleClick);
});
});
});
})();
HTML
<a class="drift-open-chat">Open Chat</a>
I hope this helps someone out there.
PS: The above javascript code must be included after you have initialized your drift widget.
You need to disable that through the application: turn off the Playbooks.
Here is the link to do so: https://app.drift.com/playbooks
Hope it helps.
Using RecordRTC as an extension and also in my development work. Great work!
Is there a way my site can programatically record a div only, instead of the whole tab?
var myformat = {enableTabCaptureAPI: true, enableSpeakers: true}
if(typeof RecordRTC_Extension === 'undefined') {
alert('RecordRTC chrome extension is either disabled or not installed.');
} else {
var recorder = new RecordRTC_Extension();
//recorder.startRecording(recorder.getSupoortedFormats()[4], function() {
recorder.startRecording(myformat, function() {
setTimeout(function() {
recorder.stopRecording(function(blob) {
console.log(blob.size, blob);
var url = URL.createObjectURL(blob);
invokeSaveAsDialog(blob);
video.src = url;
});
}, 3000);
});
}
You do not need a chrome extension to record a DIV. I'm copying here complete demo that can record a DIV.
Start/Stop buttons:
<button id="btn-start-recording">Start Recording</button>
<button id="btn-stop-recording" disabled>Stop Recording</button>
DIV to be recorded:
<div id="element-to-record">
<input value="type something">
</div>
Optionally a hidden CANVAS:
<canvas id="background-canvas" style="position:absolute; top:-99999999px; left:-9999999999px;"></canvas>
Hidden canvas is used to draw DIV and get webp images. It is till an optional step. You can either append it to he DOM or keep in the memory.
Link RecordRTC and HTML-2-Canvas:
<script src="https://cdn.WebRTC-Experiment.com/RecordRTC.js"></script>
<script src="https://cdn.webrtc-experiment.com/html2canvas.min.js"></script>
Complete javascript code:
var elementToRecord = document.getElementById('element-to-record');
var canvas2d = document.getElementById('background-canvas');
var context = canvas2d.getContext('2d');
canvas2d.width = elementToRecord.clientWidth;
canvas2d.height = elementToRecord.clientHeight;
var isRecordingStarted = false;
var isStoppedRecording = false;
(function looper() {
if(!isRecordingStarted) {
return setTimeout(looper, 500);
}
html2canvas(elementToRecord).then(function(canvas) {
context.clearRect(0, 0, canvas2d.width, canvas2d.height);
context.drawImage(canvas, 0, 0, canvas2d.width, canvas2d.height);
if(isStoppedRecording) {
return;
}
requestAnimationFrame(looper);
});
})();
var recorder = new RecordRTC(canvas2d, {
type: 'canvas'
});
document.getElementById('btn-start-recording').onclick = function() {
this.disabled = true;
isStoppedRecording =false;
isRecordingStarted = true;
recorder.startRecording();
document.getElementById('btn-stop-recording').disabled = false;
};
document.getElementById('btn-stop-recording').onclick = function() {
this.disabled = true;
recorder.stopRecording(function() {
isRecordingStarted = false;
isStoppedRecording = true;
var blob = recorder.getBlob();
// document.getElementById('preview-video').srcObject = null;
document.getElementById('preview-video').src = URL.createObjectURL(blob);
document.getElementById('preview-video').parentNode.style.display = 'block';
elementToRecord.style.display = 'none';
// window.open(URL.createObjectURL(blob));
});
};
ONLINE demo:
https://www.webrtc-experiment.com/RecordRTC/simple-demos/recording-html-element.html
I'm currently using the angular-file-upload directive, and I'm pretty much using the exact codes from the demo.
I need to add a step in there to test for the dimension of the image, and I am only currently able to do with via jQuery/javascript.
Just wondering if there's a "angular" way to check for the dimension of the image before it's being uploaded?
$scope.uploadImage = function($files) {
$scope.selectedFiles = [];
$scope.progress = [];
if ($scope.upload && $scope.upload.length > 0) {
for (var i = 0; i < $scope.upload.length; i++) {
if ($scope.upload[i] !== null) {
$scope.upload[i].abort();
}
}
}
$scope.upload = [];
$scope.uploadResult = [];
$scope.selectedFiles = $files;
$scope.dataUrls = [];
for ( var j = 0; j < $files.length; j++) {
var $file = $files[j];
if (/*$scope.fileReaderSupported && */$file.type.indexOf('image') > -1) {
var fileReader = new FileReader();
fileReader.readAsDataURL($files[j]);
var loadFile = function(fileReader, index) {
fileReader.onload = function(e) {
$timeout(function() {
$scope.dataUrls[index] = e.target.result;
//------Suggestions?-------//
$('#image-upload-landscape').on('load', function(){
console.log($(this).width());
});
//-------------------------//
});
};
}(fileReader, j);
}
$scope.progress[j] = -1;
if ($scope.uploadRightAway) {
$scope.start(j);
}
}
};
I think you can do it by:
var reader = new FileReader();
reader.onload = onLoadFile;
reader.readAsDataURL(filtItem._file);
function onLoadFile(event) {
var img = new Image();
img.src = event.target.result;
console.log(img.width, img.height)
}
This is the code snippet copied from https://github.com/nervgh/angular-file-upload/blob/master/examples/image-preview/directives.js.
I think this is more angularjs. However, you may need to modify it to fit your requirement.
Try this code
uploader.filters.push({
name: 'asyncFilter',
fn: function(item /*{File|FileLikeObject}*/ , options, deferred) {
setTimeout(deferred.resolve, 1e3);
var reader = new FileReader();
reader.onload = onLoadFile;
reader.readAsDataURL(item);
function onLoadFile(event) {
var img = new Image();
img.onload = function(scope) {
console.log(img.width,img.height);
}
img.src = event.target.result;
}
}
});
