Please consider this very simplified sample.
Below code remove a fixed nav bar from pages when screen size is small. It is named removeFixedNavbar().
This should be done when document is loaded and when window is resized. Please see the code. Well, this code seems some how ugly (calling removeFixedNavbar() twice, is it a better way to write it (with less code).
$(document).ready(function() {
removeFixedNav();
$(window).resize(function(){
removeFixedNav();
});
});
$(document).ready(removeFixedNav);
$(window).resize(removeFixedNav);
This should work, but i think it should be doable using CSS Media Queries only (depends upon the use-case).
Even simpler could be:
$(function(){
$(window).resize(removeFixedNav).trigger("resize");
});
Placing it at bottom most part can get rid of $(function(){...})
An other equivalent version can be:
$(function(){
$(window).trigger("resize");
});
$(window).resize(removeFixedNav);
Well you call it twice in document.ready.
Place window. resize outside document.ready event.

This is the jQuery code that I am using in my WordPress website, and it's working fine.
jQuery(document).ready(function($){
$(document).on("click",".selected",function() {
$('.wvg-single-gallery-image-container').css('display','none');
})
});
I just want the code to stop working at the screen width of 766, on 766 the code does not have to work.
Let me know if there is something that can make this possible.
Thanks,
Abdullah
Consider the following.
jQuery(document).ready(function($){
$(document).on("click", ".selected", function() {
if($(window).width() < 766){
$('.wvg-single-gallery-image-container').hide();
}
});
});
If the document is not very wide, less than 766, the button will perform the action. Otherwise, nothing will happen.

You can use mediaMatch to test against a media query…
if (window.matchMedia('(max-width: 766px)')) {
$('.wvg-single-gallery-image-container').css('display','none');
}
…but that approach isn't a great one. Consider what would happen if the user resized the window after the JS had run. The inline style you are adding would still be there, but based on the wrong window size.
Instead, use JS to add and remove classes from elements. Then use those classes in your CSS with media queries.
$('.wvg-single-gallery-image-container').addClass('a-suitably-semantic-class-name);
I have a following code:
var e = document.getElementById("overlay");
e.parentNode.removeChild(e);
This code is supposed to remove the DOM element, but it doesn't. So I removed the code and added a breakpoint in its stead and input the code in the console during the pause manually, and it worked (i.e. the element was successfully removed).
This behavior seems rather strange for me, so I wanted to ask, why does it happen and what can I do to inspect this peculiar issue?
Thanks in advance.
EDIT: Thanks for quick replies. Nonetheless, I want to make it perfectly clear that the element #overlay does exist at the time of the execution of the code. Moreover, when I put a debugging breakpoint at that place in the code and execute these two lines of code, it does have an effect on this particular existent element (which it doesn't without debugging).
EDIT 2: I was asked to clarify the code. I execute the following code before the body (part of the queryloader2 plugin, which ensures image preloading):
window.addEventListener('DOMContentLoaded', function() {
new QueryLoader2(document.querySelector("body"), {});
});
No errors present (except for a 404 error because of missing image, which has no impact on Javascript).
As Teemu mentioned #overlay more than likely doesn't exist when the code is run.
For a test.. Try wrapping your code in either of these...
Javscript
window.onload = function () { /*your code*/ };
Jquery (if included)
$(document).ready(function () { /* your code*/ });
You should execute your code after the DOM tree has finished loading. One option is to wrap your code in a function that executes after the DOMContentLoaded event has been fired.
document.addEventListener("DOMContentLoaded", function(event) {
// your code
});
Look at this answer for more information: $(document).ready equivalent without jQuery
I am using Masonry.js to create a masonry style blog. The problem with this is, when I click 'Article' for example, my JS makes everything but an article disappear. Instead of all the articles filling in the gaps that were previously filled with other post types, they just stay in the same position.
Once I resize the window Masonry.js does its thing and every gap becomes filled with the articles. My question is how to FORCE this to happen without having to resize the window manually?
Note:
I have tried this link
Forcing windows resize to fire
This will not work.
$(window).resize(function(){
$('span').text('event fired!');
});
$('button').click(function(){
window.dispatchEvent(new Event('resize'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<button>Fire event</button>
<span></span>
This must work (I'm using it right now)
$(window).trigger('resize');
Hope this helps.
EDIT
Note that's jQuery syntax.
EDIT 2
i make a research of masonry.js (I don't meet it before this post), and I think that you can solve this problem like this:
$(window).on('resize', function () {
$('#element').masonry('reloadItems');
});
$(window).trigger("resize");
Good luck
I managed to fix this.
$('#article-options li').on('click', function() {
setTimeout(function() {
var $grid = $('#blog-container').masonry({
columnWidth: 80
});
// change size of item by toggling gigante class
$(this).toggleClass('gigante');
// trigger layout after item size changes
$grid.masonry('layout');
}, 200);
});
Each 'section' of the blog of mine is in a ul called article options so when an option is clicked (therefore changed) it will run this function.
I have set a timeout as JS was running a bit behind and making me click twice for the code to run.
I defined a new masonry grid, I defined this as the overall blog container which holds all posts. I then had code in place which recognised the click function on a section and toggled a class which pops everything back into their correct positioning.
As for details, i'm not too sure as this is not my module. If anyone has any valuable information that might help others, comment and I will update my answer. Thanks everyone.
Basically I did a rollover in css but i want it in javascript instead. Also I want,once my page is loaded one of the pictures would be automatically selected. I tried this code for that but its not working.. any ideas? for some reason its not calling the function. ps: the id is called clicked3 as well in my html
<script type="text/javascript">
window.onLoad=function(){
clicked3();
}
function clicked3(){
document.getElementById("clicked3").style.backgroundPosition = "-198px top";
}
</script>
Do yourself a favor and use a javascript library, such as jQuery...
1) Javascript is case sensitive, so window.onLoad isn't the same as window.onload (correct sintax)
2) If your image is exactly 198px wide (you're hiding the image), you may have forgot to add background-repeat:no-repeat; in your css, making you see a copy of that image
Anyway, your sintax for changing background position is correct, see it in action here:
http://jsfiddle.net/zszB4/
The real reason your code isn't working is because you're assigning your function to a non-existent event handler onLoad. window.onload is the correct syntax, notice it's all lower case.
http://jsfiddle.net/9Kh8f/3/
You dont need the window.onload=function.. you can just call...
window.onload=clicked3();
Working demo here for you :)

I'm new to jquery and bumped into a problem i can't fix
I want that on pageload my content is sliding down so i use the next code:
$(document).ready(function () {
$("#content").hide();
$("#content").slideDown(1000);
});
when i load the page the content slides down narmally, than the content gets hidden and slides down again.
When i go to the css and do #content{display: none;} instead of $("#content").hide(); everything works fine. (can't use this for browsers without js)
Does anyone know the cause of this?
Thanks!
You are saying that everything works fine while using css #content{display: none;}
than i offer u to use Jquery .css() method( http://api.jquery.com/css/ )..
u can use it like :
$(document).ready(function () {
$("#content").css( { 'display' : 'none' } );
$("#content").slideDown(1000);
});
sipmle as that.
and i also agree with #Billy Moon , it can be a browser specific bug or u may be calling a page refresh command, somewhere within ur code.
Your code has no problem inside. It's somewhere else in your code.
isn't that function call in some function that is called twice?
