I have 4 JS scripts and 1 JQuery script src at the bottom of my HTML page. When I include the JQuery script, though, the code in JS script delayed.js only works for a second, then stops. All the other JS scripts work. How can I fix this?
I have tried:
changing the order of the scripts on the HTML page
changing the JS code in delayed.js into JQuery
moving the JS code in delayed.js into another JS script in which JS is working
Changing the JQuery reference (e.g. from Google APIs)
Here's the code at the bottom of my HTML page:
<script defer src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
<script defer src="assets/js/skel.min.js"></script>
<script defer src="assets/js/util.js"></script>
<script defer src="assets/js/main.js"></script>
<script defer src="assets/js/delayed.js"></script>
Here's the code in delayed.js. It's for changing the style of the nav item according to the specific page you're on, so as a user the page you're currently on is always clear.
if (document.body.classList.contains('index')){
document.getElementById('nav-wwd').classList.add('selected');
}
if (document.body.classList.contains('approach')){
document.getElementById('nav-oa').classList.add('selected');
}
if (document.body.classList.contains('about')){
document.getElementById('nav-wwa').classList.add('selected');
}
if (document.body.classList.contains('insights')){
document.getElementById('nav-oi').classList.add('selected');
}
if (document.body.classList.contains('contactus')){
document.getElementById('nav-c').classList.add('selected');
}
Thanks in advance for any advice you can give.

I'm very new to all this and having trouble installing it to my my backend code. Where does it go? Below my footer with all my JS?
Like, what does it mean by:
Popup initialization code should be executed after document ready?
Could someone please let me know if this is correct:
$(document).ready(function() {
$('.image-link').magnificPopup({
type:'image'
});
});
I've put this inside a script tag.
Which lies underneath my closing footer but just doesn't seem to work.
yes, put all necessary css and js files first. js files can be included in header or footer. It doesn't matter (footer is preferred location for loading js nowadays). However, don't call the magnificPopup() function before loading necessary js files. After all are loaded you can use your code in docready like you mentioned.
<!-- jQuery 1.7.2+ or Zepto.js 1.0+ -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<!-- Magnific Popup core JS file -->
<script src="FOLDER_WHERE_YOU_KEPT_THIS_JS_FILE/jquery.magnific-popup.js"></script>
<script>
$(document).ready(function() {
$('.image-link').magnificPopup({
type:'image'
});
});
</script>
This should work if there no other js conflict and you created the html correctly like mentioned in the doc. Let me know if there is more confusion or if still you could not make it work...
I have this code in the footer of my html page
<script type="text/javascript">
// using jQuery
$('video,audio').mediaelementplayer();
</script>
the above code is adding video player on the html page.
Now I have created a separate js file in which I have already have some line of code which is creating owl sliders, tooltips, number counters etc.
When I add the above code into that separate js file it does not work, instead when I keep it in the footer of the html page it works fine.
Try placing your code within $(function(){ ... }. This will execute when the DOM is loaded (currently your code is being executed before jQuery is loaded, if you check the JavaScript console, you will see an error something like $ is not defined)
$(function(){
$('video,audio').mediaelementplayer();
});
or
$( document ).ready(function() {
$('video,audio').mediaelementplayer();
});
You can read about what that is doing here. $(function() is the same as $( document ).ready()
your html(basically) should look like this:
<html>
<head>
</head>
<body>
<!-- html code here -->
<!-- add jquery lib -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<!-- your script -->
<script src="you/file/path.js"></script>
</body>
</html>
and your jquery file:
jQuery(function($) {
// your functions here
$('video,audio').mediaelementplayer();
});
Do you have a proper link to the separate js file in your page, generally at the bottom of the body? It should look something like this:
<script type="text/javascript" src="/joyride_odoo_models/static/js/scripts.js"/>
If you've done that properly, have you tried clearing your browser cache? You may need to do that to detect new javascript files.
How do you call your external js file ?
You must add your references js before your external js file.
you must add your function on document.ready.
You may wait until jQuery is full loaded or ready.
Ex.
$(document).ready(function($) {
// Your code goes here
$('video,audio').mediaelementplayer();
});
This code goes in external js file, then you need to include the file in the HTML
<script type="text/javascript" src="path/to/your/js/file"></script>
I'm new to web development, and was having issues with two plug-ins. I already found a workaround to solve it, but I'm not convinced at all about what I did, so I ask you guys if you can enlighten me on what is this about.
The page in question uses SlimScroll and DataTables plugins. At first, I had an HTML file like this one.
<body>
<!-- STUFF -->
<!-- SCRIPTS -->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.2/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.11.4/jquery-ui.min.js"></script>
<script src="plugins/bootstrap/js/bootstrap.min.js" type="text/javascript"></script>
<script src="plugins/slimScroll/jquery.slimscroll.min.js" type="text/javascript"></script>
<script src="plugins/DataTables/datatables.min.js" type="text/javascript"></script>
<script src="assets/scripts/tablas.js" type="text/javascript"></script>
<script src="assets/scripts/general.js" type="text/javascript"></script>
At the bottom, general.js is used to handle click events and other stuff, and tablas.js has the code that picks up a file with data and displays it in DataTables. The relevant code from general.js:
$(document).ready(function() {
$('#contenedor-menu').slimScroll({
height: '100%'
});});
And the code for tablas.js:
$(document).ready(function() {
$('#tablita').DataTable( {
"ajax": 'data/COut2.txt',
} );});
With this structure, when I load the page, SlimScroll fails with the message in the console: "TypeError: $(...).slimScroll is not a function"
Then after touching around, I switched the order of the scripts in the HTML file. I put datatables first and then slimscroll.
<script src="plugins/DataTables/datatables.min.js" type="text/javascript"></script>
<script src="plugins/slimScroll/jquery.slimscroll.min.js" type="text/javascript"></script>
And now it works ok, with no errors.
Could somebody please explain to me what's going on?
Thanks in advance!
The use of multiple $(document).ready(function() { } is the main cause of this issue. There should be only one Document Ready event handler.
You may try using the pageLoad() function or onLoad() events
Not positive but it is usually best practice to put the scripts you absolutely need before everything else in the head. This is so that the content of the page does not finish loading until all the dependencies have been loaded first.
By reordering your scripts you may have a solution that will only work some of the time.
Put all the scripts you need to load in the head and your general.js script at the end of your body element.
I am using Bootstrap as my template, and Laravel as my framework. As suggested within the examples, you should load your jQuery script at the bottom of the page - to speed up the loading.
Within my application, I have this function that checks if an alert exists in the session, and if so, show it:
$(document).ready(function() {
toastr.options = {
"closeButton": false
};
toastr. {
{
Session::get('flash_notification.level')
}
}('{{ Session::get('
flash_notification.message ') }}')
});
This is shown above where I load the jQuery script:
#if (Session::has('flash_notification.message'))
<script>
The above script is loaded here.
</script>
#endif
#yield('content')
</div>
<!-- Scripts -->
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
In order to get this working, I need to declare my jQuery file in the header of the template, but I know this isn't best practice. I initially thought that by using the $(document).ready() method, it would resolve this, but it doesn't.
Any help would be greatly appreciated.
It is best to put the script calls in the footer so they are loaded last. This means that any other JS you write will need to be below them. You could add your other JS to another file which is included after the jQuery load.
If you cannot, you could add it to the header and add the defer attribute to the script tag to defer it's loading.
Option 1 should be preferred though.
I'm learning jQuery, and I'm running into a small problem. jQuery code works when I put it directly in my tags in my HTML, but when I import it from a different file, nothing happens. These are my script tags in HTML:
<script type="text/javascript" src="scripts/jquery-1.10.2.js"></script>
<script type="text/javascript" src="scripts/test.js"></script> <!--This is my jQuery code-->
test.js contains the following code:
$(document).ready(function(){
console.log("Hello");
});
When the page loads, the console is empty. However, when I paste the following code as so, in my html document, everything works fine.
<script>
$(document).ready(function(){
console.log("Hello");
});
</script>
Do you really have a folder named scripts in the folder where your HTML files exist? Otherwise try changing this src="scripts/jquery-1.10.2.js" to probably this: src="/scripts/jquery-1.10.2.js"
You can check by browsing to http://yoururl/scripts/jquery-1.10.2.js, the Jquery code should show up. If it's not there, you have to make sure that you include the right folder/file.
Yes.You will be able to push your scripts in 2 ways::
1-push your scripts in tag like>>
<script>$(document).ready(function(){alert("Welcome Dear");});</script>
2-push your inline scripts with attributes like>>
<button type='button' onclick="$(this).hide()">Hide Me</button>
make sure that the scripts folder contain test.js make sure that the extension is correct ..sometimes I make the same same mistake, instead of test.js i save it as test.js.txt
Try putting
<script type="text/javascript" src="scripts/jquery-1.10.2.js"></script>
in the body rather than the head.
