What should I use to customize HTML5 video player(add own buttons, add css styles)? Now we use javascript plug-ins, but sometimes these pulg-ins are loaded before Iframe DOM. Can you provide us an event which can be used to determine that DOM is loaded?
You can do that in many places.
In HTML:
<body onload="alert('DOM loaded!')">
In JavaScript:
window.onload=function(){
alert("DOM loaded!")
};
In jQuery:
$(document).ready(function() {
alert("DOM loaded!")
});
// or
$(function() {
alert("DOM loaded!")
});
I think you will want the templateReadyHandler - see http://support.brightcove.com/en/video-cloud/docs/player-error-handling

I need to execute some JavaScript code when the page has fully loaded. This includes things like images.
I know you can check if the DOM is ready, but I don’t know if this is the same as when the page is fully loaded.
That's called load. It came waaaaay before DOM ready was around, and DOM ready was actually created for the exact reason that load waited on images.
window.addEventListener('load', function () {
alert("It's loaded!")
})
For completeness sake, you might also want to bind it to DOMContentLoaded, which is now widely supported
document.addEventListener("DOMContentLoaded", function(event){
// your code here
});
More info: https://developer.mozilla.org/en-US/docs/Web/Events/DOMContentLoaded
Usually you can use window.onload, but you may notice that recent browsers don't fire window.onload when you use the back/forward history buttons.
Some people suggest weird contortions to work around this problem, but really if you just make a window.onunload handler (even one that doesn't do anything), this caching behavior will be disabled in all browsers. The MDN documents this "feature" pretty well, but for some reason there are still people using setInterval and other weird hacks.
Some versions of Opera have a bug that can be worked around by adding the following somewhere in your page:
<script>history.navigationMode = 'compatible';</script>
If you're just trying to get a javascript function called once per-view (and not necessarily after the DOM is finished loading), you can do something like this:
<img src="javascript:location.href='javascript:yourFunction();';">
For example, I use this trick to preload a very large file into the cache on a loading screen:
<img src="bigfile"
onload="this.location.href='javascript:location.href=\'javascript:doredir();\';';doredir();">
Try this it Only Run After Entire Page Has Loaded
By Javascript
window.onload = function(){
// code goes here
};
By Jquery
$(window).bind("load", function() {
// code goes here
});
Try this code
document.onreadystatechange = function () {
if (document.readyState == "complete") {
initApplication();
}
}
visit https://developer.mozilla.org/en-US/docs/DOM/document.readyState for more details
Javascript using the onLoad() event, will wait for the page to be loaded before executing.
<body onload="somecode();" >
If you're using the jQuery framework's document ready function the code will load as soon as the DOM is loaded and before the page contents are loaded:
$(document).ready(function() {
// jQuery code goes here
});
the window.onload event will fire when everything is loaded, including images etc.
You would want to check the DOM ready status if you wanted your js code to execute as early as possible, but you still need to access DOM elements.
You may want to use window.onload, as the docs indicate that it's not fired until both the DOM is ready and ALL of the other assets in the page (images, etc.) are loaded.
In modern browsers with modern javascript (>= 2015) you can add type="module" to your script tag, and everything inside that script will execute after whole page loads. e.g:
<script type="module">
alert("runs after") // Whole page loads before this line execute
</script>
<script>
alert("runs before")
</script>
also older browsers will understand nomodule attribute. Something like this:
<script nomodule>
alert("tuns after")
</script>
For more information you can visit javascript.info.
And here's a way to do it with PrototypeJS:
Event.observe(window, 'load', function(event) {
// Do stuff
});
The onload property of the GlobalEventHandlers mixin is an event
handler for the load event of a Window, XMLHttpRequest, element,
etc., which fires when the resource has loaded.
So basically javascript already has onload method on window which get executed which page fully loaded including images...
You can do something:
var spinner = true;
window.onload = function() {
//whatever you like to do now, for example hide the spinner in this case
spinner = false;
};
Completing the answers from #Matchu and #abSiddique.
This:
window.addEventListener('load', (event) => {
console.log('page is fully loaded');
});
Is the same as this but using the onload event handler property:
window.onload = (event) => {
console.log('page is fully loaded');
};

If you need to use many onload use $(window).load instead (jQuery):
$(window).load(function() {
//code
});
2019 update: This is was the answer that worked for me. As I needed multiple ajax requests to fire and return data first to count the list items.
$(document).ajaxComplete(function(){
alert("Everything is ready now!");
});
Here is the code i am using to change value of html element ***
<a class="classname" href="Vtech.com"> This text to be chnage</a>
<script type="text/javascript">
document.getElementsByClassName("classname")[0].innerHTML = "aaaaaaqwerty";
</script>
how can I change this text on page load instans
Seems you need to add DOMContentLoaded or put your script before </body>
Native JavaScript solution
document.addEventListener("DOMContentLoaded", function(event) {
document.getElementsByClassName("classname")[0].innerHTML = "qwerty";
});
Add your script before </body>
Version with jQuery
$(funtion(){
$(".classname:first").text("qwerty");
});
You can use css selector, but it can be not safe, because this method return first occurance:
document.querySelector(".classname");
By the way, almost all developers use some js framework: jQuery, prototype, extJs, etc
$(document).ready(funtion(){
$(".classname").text("aaaaaaqwerty");
});
Using jquery (I refered to jquery, since you have tagged it in your question), you could achieve this like below:
$(funtion(){
$("a .classname")[0].text("aaaaaaqwerty");
});
You could use this
document.addEventListener("DOMContentLoaded", function(event) {
document.getElementsByClassName("classname")[0].innerHTML = "some texts";
});
Using jQuery
$(document).ready(function(){
$(".classname").eq(0).val("aaaaaaqwerty");
});
I need to migrate a working jQuery script - over to Mootools to meet the requirements of my project.
The working jquery code is:
$('#video').bind('ended', function() {
//Functions on end here.
});
I have tried the following with Mootools...
document.id('video').addEvent('ended', function () {
//Functions here
});
and
document.id('video').addEvent('ended', function () {
//Functions here
}.bind(this));
However to no effect :( Can any one point me in the right direction please?
Thanks!
MooTools does not support HTML5 media tags events. After adding block written here You can use:
$('myVideo').addEvent('ended', function(){
//Functions here
});
Here myVideo is an id of tag:
<video id="myVideo"></video>
I have this code
<script type="text/javascript">
$("#main_photo_display").load(function(){
alert("loaded");
});
</script>
<div id="main_photo_display"></div>
I need it to do something once that div has loaded. Currently it does nothing. When I substitute window for "#main_photo_display" it works. I have googled and I keep coming across .load as how to check if a page element has been loaded.
The load event is sent to an element when it and all sub-elements have
been completely loaded. This event can be sent to any element
associated with a URL: images, scripts, frames, iframes, and the
window object.
Source: http://api.jquery.com/load-event/
Further down on the same page they state:
It doesn't correctly bubble up the DOM tree
So you can't delegate this event, the event handler must be attached to the element on which the load event fires.
Or you can run the script after the DOM is ready like so:
<script type="text/javascript">
$(document).ready(function() {
$("#main_photo_display").load(function(){
alert("loaded");
});
});
</script>
<div id="main_photo_display"></div>
Sorry I think I read it wrong :) You need this:
<script type="text/javascript">
$(document).ready(function() {
alert('loaded');
});
</script>
A plain div does not have a load event except when you are loading content into it with ajax (which I don't think is what you are doing here). If your code is physically located after the div in your page, then the div will be available and ready for your code to operate on it (you don't have to check anything).
If your code is located before the div in the page, then you can use jQuery's .ready() method to know when it is safe to access the div:
<script type="text/javascript">
$(document).ready(function() {
// safe to access $("#main_photo_display") here
});
</script>
<div id="main_photo_display"></div>
I don't think a DIV fires a loaded event. If there was a blank.gif image within the DIV, you could attach the $.load() function to that.
<div id="main_photo_display">
..... Other Content .....
<img class="loadcheck" src="blank.gif" width="0" height="0" />
</div>
<script type="text/javascript">
$(document).ready(function(){
$("#main_photo_display img.loadcheck").load(function(){
alert("loaded");
});
});
</script>
You can't do that: load events are not fired on just any HTML element, only on those that require loading an external resource.
The best way to ensure the element is loaded is to put the script tag after it in the markup.
<div id="main_photo_display"></div>
<script type="text/javascript">
alert("loaded");
</script>
The Javascript will not be run before the div is parsed.
I have a sort of workaround, and it is sloppy (please comment out if you have notes).
It is useful when you have a javascript out of your control which appends elements to your dom on a page load.
$(function () {
var counter = 0;
var intervalId = setInterval(function () {
$(document).mouseover()
}, 105);
var unbind = function () {
$(document).off('mousemove', '#label');
$(document).off('mouseover');
window.clearInterval(intervalId);
};
$(document).mouseover(function () {
$('#label').trigger('mousemove');
counter++;
if (jivositecounter > 200) unbind();
});
$(document).on('mousemove', '#label', function () {
console.log(counter);
...doing our stuff when #label appears
unbind();
});
});
I'm using this jQuery to render a text box onClick. But, It's not rendering... Also, on a side note I'm using Drupal 7. I have the jQuery in the Head tags of the html.php.
<script type="text/javascript">
$(document).ready(function() {
$("#front-background").hide();
$(window).load(function() {
$('#links-top-1').hover(function() {
$('#front-background').fadeIn(2000);
});
});
});
</script>
This may also be because of how Drupal handles compatibility with other JavaScript libraries.
You can wrap your jQuery function in:
(function ($) {
//your existing code
})(jQuery);
or if you're comfortable theming using the template.php file, you can add the JS through the function drupal_add_js().
See http://drupal.org/node/171213 for more details.
You dont need window load event if you are already using $(document).ready method. Try this.
$(document).ready(function() {
$("#front-background").hide();
$('#links-top-1').hover(function() {
$('#front-background').fadeIn(2000);
});
});
I didn't see any onClick functionality there. This should work:
CSS:
#front-background {
display:none;
}
JQuery hover replacement. Fade in on hover, fadeout on leave
$(function() {
$('#links-top-1').hover(function() {
$('#front-background').fadeIn(2000);
},function(){
$('#front-background').fadeOut(2000)
});
});
