so im trying to rotate a series of 4 photos using the code above, but when i load my page, nothing happens the original src photo stays
in my HTML i have id="pauls" src="stpauls" and linked my
file to my index.html file
regards
check browser console for error, create the function inside the callback of ready() function
var myImage = document.getElementById("pauls");
var imageArray = ["https://singlecolorimage.com/get/5b71aa/100x100", "https://singlecolorimage.com/get/31a57e/100x100", "https://singlecolorimage.com/get/55ae19/100x100", "https://singlecolorimage.com/get/ae1946/100x100"];
var imageIndex = 0;
$(document).ready(function() {
function changeImage() {
myImage.setAttribute("src", imageArray[imageIndex]);
imageIndex++;
if (imageIndex >= imageArray.length) {
imageIndex = 0;
}
}
setInterval(changeImage, 1000);
});

I can not get all thumbnails using Google Drive API. They are randomly displayed.
Here is the code I use:
<script src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<script type="text/javascript">
function gapiLoaded() {
gapi.load('client', intializeGapiClient);
}
async function intializeGapiClient() {
await gapi.client.setToken({access_token:'ya29.a0AVvZVs...'});
loadDriveApi();
};
function loadDriveApi() {
gapi.client.load('drive', 'v3', listFiles);
}
function listFiles() {
var parentID = 'root';
var request = gapi.client.drive.files.list({
'q': `'${parentID}' in parents and trashed = false`,
'fields': "nextPageToken, files(id,thumbnailLink,size,webViewLink,parents,shared,name,createdTime,mimeType,properties)",
});
_files = [];
i = 0;
request.execute(function(resp) {
var files = resp.files;
if (files && files.length > 0) {
for (var i = 0; i < files.length; i++) {
var file = files[i];
_files += file.id+'|'+file.name+'|'+file.size+'|'+file.thumbnailLink+'|'+file.mimeType+'|'+file.webViewLink+'|'+file.parents+'|'+file.createdTime+'\r\n';
if (i+1 == files.length){
console.log(_files);
}
}
}
});
}
</script>
<script async defer src="https://apis.google.com/js/api.js" onload="gapiLoaded();"></script>
and here is animated gif displaying the result: https://i.postimg.cc/26FMy6Hs/g1.gif
How to get all thumbnails, please?
I would like to play multiple audio files one by one. I have read the same question, but I have found the links to the original answer not working and question unanswered.
Original answer
<audio id="mySound" controls><source src="http://www.hvalur.org/audio/uploaded_files/ds_umkomuleysi_0_0.mp3" type="audio/mpeg"></audio>
<audio id="mySound1" ><source src="http://www.hvalur.org/audio/uploaded_files/ds_ljosmyndavel_0_0.mp3" type="audio/mpeg"></audio>
I want the first sound started by the user action (pressing the play button) and then the following sound(s) playing one by one.
The usage of this example will be practising of understanding of the telephone numbers read by native speaker.
I would do something like that:
var mySound = document.getElementById("mySound");
var mySound1 = document.getElementById("mySound1");
var mySound2 = document.getElementById("mySound2");
var mySound3 = document.getElementById("mySound3");
var mySoundArray = [mySound, mySound1, mySound2, mySound3];
var mySoundArrayPos = 0;
var myButton = document.getElementById("myButton");
myButton.addEventListener("click", function(event) {
mySound.play();
mySoundArrayPos = 0;
startSoundTimer();
});
const startSoundTimer = () => {
var mySoundTimer = setInterval(() => {
if (mySoundArray[mySoundArrayPos].currentTime >= mySoundArray[mySoundArrayPos].duration) {
if (mySoundArrayPos < mySoundArray.length -1) {
mySoundArrayPos += 1;
mySoundArray[mySoundArrayPos].play();
} else {
clearInterval(mySoundTimer);
}
}
}, 10);
};
I don't know if the 10ms are a bit too fast, but I think, it's legit.
Javascript
=============== `playaudio(i) {
var thisme = this;
var audio = new Audio(thisme.model.audioFiles[i].audioUrl);
audio.play();
audio.addEventListener("ended", function () {
i = i + 1;
console.log(i);
if (i < thisme.model.audioFiles.length) {
audio.src = thisme.model.audioFiles[i].audioUrl;
audio.play();
}
}, false);
}
}`
HTML
====`<span class='chunkAudio' (click)="playaudio(0)">
<img class='playbtn' src="{{model.playerImageUrl}}" />
</span>`
could someone please help me to find out why this won't work on safari browser? It seems to work really well in all other browsers apart from Safari. I really could not work it out.
Any help will be most appreciated.

How or where can i get a counter something similar to this? I am aware of the sliders but the counter in the slider is something i am looking for and developing the website with HTML5, jquery.
I'm not sure I got the question 100%, anyway, here's my attempt:
JSFiddle
var Counter = function(options) {
var start = options.start;
this.init = function() {
var self = this;
var t = window.setInterval(function() {
start+=1;
self.render(start);
}, options.interval)
}
this.render = function(number) {
var stringVal = number.toString();
var arr = stringVal.split('');
for(var i = 0; i < arr.length ; i++) {
$('.number').eq(i).text(arr[i]);
}
}
this.init();
}
var counter = new Counter({
start: 123456777,
interval: 1000 //milliseconds
});
Got this code, that only works when alert (markers.length); is uncommented.
When this javascript alert not shown I dont get any Markers.. Really weird!!
In the body tag I have <body onload="load()" onunload="GUnload()">
Previoslly the load() function is called and other functions :
function showAddress(address) {
if (geocoder) {//+', '+init_street
geocoder.getLatLng(address,
function(point) {
if (!point) {
document.getElementById("place").value="not found";
//alert(address + " not found");
} else {
// document.getElementById("place").value=point.y.toFixed(4) + "," + point.x.toFixed(4);
map.setCenter(point, 16);
marker.setPoint(point);
//marker.openInfoWindowHtml(address);
}
}
);
}
}
//from a point returns and address!
function showPointAddress(response) {
if (!response || response.Status.code != 200) {//not found
//alert("Status Code:" + response.Status.code);
document.getElementById("place").value="not found";
}
else {//found
map.setCenter(marker.getPoint(), 16);
place = response.Placemark[0];
document.getElementById("place").value=place.address;
//document.getElementById("place").value=marker.getPoint().toUrlValue();
}
}
// Creates a marker at the given point with the given number icon and text
function createMarker(p,text) {
var marker = new GMarker(p);
if (text!=""){
GEvent.addListener(marker, "click", function() {
marker.openInfoWindowHtml(text);});
}
return marker;
}
` var geocoder = null;`
` var map = null;`
function load() {//loading the map
if (GBrowserIsCompatible()) {
map = new GMap2(document.getElementById("map"));
map.enableScrollWheelZoom();
geocoder = new GClientGeocoder();
if (init_street!=""){
geocoder.getLatLng(init_street,function(point) {//set center point in map
if (point){
map.setCenter(point, zoom);
map.addOverlay(createMarker(point,init_street));
map.openInfoWindow(point,init_street);
}
});
}
map.addControl(new GLargeMapControl());
map.setMapType(G_NORMAL_MAP);
}
}`
function(data, responseCode) {
if(responseCode == 200) {
var texts = [];
var addresses = [];
var xml = GXml.parse(data);
var markers = xml.documentElement.getElementsByTagName("item");
alert (markers.length);
for (var i = 0; i < markers.length; i++) {
var address=markers[i].getElementsByTagName('address').item(0).childNodes.item(0).nodeValue;
if (address!=null){
//alert (address);
var title=markers[i].getElementsByTagName('title').item(0).childNodes.item(0).nodeValue;
var link=markers[i].getElementsByTagName('link').item(0).childNodes.item(0).nodeValue;
var desc=markers[i].getElementsByTagName('description').item(0).childNodes.item(0).nodeValue;
desc=desc.substr(0,220);//limit
addresses.push(address);
texts.push("<div style='width: 200px'><a target='_blank' href='" +link+"'>"+title+"</a><br />"+desc+"</div>");
}//if
}//for
for (var i = 0; i < addresses.length; i++) {
geocoder.getLatLng(addresses[i], function (current) {
return function(point) {
if (point) map.addOverlay(createMarker(point,texts[current]));
}
}(i));
}
}//if });
I Understand the issue of needing a callback function to load the markers, but Im lost..
Any help apreciated!! ;)
Thx in advanced!!
This usually happens when fetching data with Ajax or similar. Basically when you fetch the data you need to utilize a callback function to wait for the data. If you don't there is no data to execute on. However, if you pause the execution with a alert() the data will have been fetched in the background.
Think of it as the waiting for the DOM to load before executing Javascript on the page.
I can't give you a better answer as you have not included the code that is calling the function you included.
