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.
What I want is to show loading animation while image is loading.
Basically I have large system and all code bits are injected using ngInclude.
So if I have to construct the bit I'm interested in it would look like:
<div ng-controller="MyTabCtrl">
<div id="preview-panel" waiting-animation="img/loading.gif" waiting-property="isLoadingPreview">
<ng-include src="htmlInclude" />
</div>
</div>
And htmlInclude html for example would just be a div with img.
The htmlInclude changes when I click different posts I have.
So far I loaded low quality images so loading wasn't an issue - it was quick. Now I want to load high-quality images and their loading takes a while.
So all my included html (text, buttons etc) is loaded, and the image gets replaced after a few moments.
I tried to fiddle with different events I found in other questions, but they don't seem to be working for me. Either the loading doesn't appear at all, or it appears and stays there even after loading is complete.
Some stuff I tried is:
$scope.$on('$includeContentLoaded', function () {
$scope.isLoadingPreview = false ;
});
or
$scope.$on('$viewContentLoaded', function() {
$scope.isLoadingPreview = false ;
});
How can I make this happen?
Thanks!
I know there is a bunch of questions like this but none really answering my question.
I had make a preloader with css animation and I want to be synchronised with page load. I can trigger the animation on page load but I want to manage the time that animation last somehow so to follow exactly the page load (even if it's too fast).
An example : http://jsfiddle.net/RgPU7/
I want the 'filling' effect to follow page load time.
Right now I just apply a delay and a fadeout effect to the modal that wraps the css animation.
jQuery(window).load(function(){
$(".modal").delay(3000).fadeOut(1000);
});
Any suggestions would be great. Thanks!
You can always delay a function like this
setTimeout(function() { your_func(); }, 5000);
or you can do something like this
$(this).fadeOut(500, function(){
//Do something
$(this).fadeIn(700);
});
I hope this helps.
I'm a creating a loading screen for website I am making. The website loads many images, scripts, etc. The HTML and CSS part is great, but I need a way to guarantee that the "loading..." image will be loaded before anything else.
I'm using jQuery, and everything is initiated within $(function () { ... });. I imagine that the code for this would need to be called before/outside that block, and the code to remove the loading screen will be called at the very end of that block. Currently, the loading image is set as a DIV background, which is the way I prefer it. However, if it's completely necessary, I will settle for an IMG tag.
Update: (solution)
I was able to answer my own question by using a combination of Robin and Vlad's responses. Both were very good, and excellent answers, however the problem is that they were aimed to load an image before another image, rather than load an image before anything else. (CSS, JS, etc...)
Here's the dirty version of what I came up with:
var files = [new Image(), document.createElement('link'), document.createElement('script')];
files[0].setAttribute('src', 'images/loading.gif');
files[1].setAttribute('rel', 'stylesheet');
files[1].setAttribute('type', 'text/css');
files[1].setAttribute('href', 'test.css');
files[2].setAttribute('type', 'text/javascript');
files[2].setAttribute('src', 'js/jquery-1.5.1.min.js');
window.onload = function (e) {
document.getElementsByTagName('head')[0].appendChild(files[1]);
document.getElementsByTagName('head')[0].appendChild(files[2]);
}
Taking a look at the load sequence on the network tab of Chrome's developer console shows that 'loading.gif' is loaded first, then 4 dummy images, then 'test.css', and then 'jquery.1.5.1.min.js'. The CSS and JS files don't begin to load, until they've been inserted into the head tag. This is exactly what I want.
I'm predicting that I may begin to have some problems, however, when I begin to load a list of files. Chrome reports that sometimes the JS file is loaded first, but the majority of the time the CSS file is loaded first. This isn't a problem, except when I begin to add files to load, I will need to ensure that jQuery is loaded before a script file that uses jQuery.
If anyone has a solution for this, or a way to detect when the CSS/JS files are finished loading, using this method, then please comment. Though, I'm not sure that it's going to be a problem yet. I may need to ask a new question in the future about this, if I start to run into problems.
Thank you to every who has helped with this issue.
Update: (glitch fix)
I ended up running into a lot of problem with this method, because the script files were being loaded asynchronously. If I would clear the browser cache, and then load the page, it would finish loading my jquery dependent files first. Then if I refreshed the page, it would work, because jquery was loaded from cache. I solved this by setting up an array of files to load, then putting the load script into a function. Then I would step through each array item using this code:
element.onload = function() {
++i; _step();
}
element.onreadystatechange = function() {
if (("loaded" === element.readyState || "complete" === element.readyState)) { ++i; _step(); }
}
You can reuse resource prealoding browser support.
I'm not sure it works across all browsers but in my case this approach helps me to load images first. Also it allows to define concrete images so UI specific could be skipped
First define in header what resource you want to preload and define resource priority
<link rel="preload" href="link-to-image" as="image">
or
<link rel="preload" href="link-to-image">
Second line allow to increase loading priority across all object types (scripts / images / styles). First line - only through images.
Then define in body link to image as usual:
<img src="link-to-image" alt="">
Here is my working example
https://jsfiddle.net/vadimb/05scfL58/
As long as the "loading..." image is positioned before any other html elements, it should load first. This of course depends on the size of the image. You could put the loading div right after the tag and position it using 'position:absolute'.
Regarding the code to remove the loading screen, one method is to do the following.
Put all the images, scripts that need to be loaded in a hidden div (display: none)
Set up a variable that will hold the total of the images / scripts to be loaded
Set up a counter variable
Attach to each image / script the "onload" event
Everytime the "onload" event is triggered it will call a function that will increment the counter variable and check if the value of the counter equals the value of the total variable
If all resources have been loaded, fire a custom event that will show the div with the images, and hide the div with the loading screen.
The code below isn't tested so it might not work. Hope it helps
var totalImages = 0;
var loadCounter = 0;
function incrementLoadCounter() {
loadCounter++;
if(loadCounter === totalImages) {
$(document).trigger('everythingLoaded');
}
}
function hideLoadingScreen() {
$('#loadingScreen').hide();
$('#divWithImages').show();
}
$(document).ready(function(e) {
$('#loadingScreen').bind('everythingLoaded', function(e) {
hideLoadingScreen();
});
var imagesToLoad = $('img.toLoad');
totalImages = imagesToLoad.length;
$.each(imagesToLoad, function(i, item) {
$(item).load(function(e) {
incrementLoadCounter();
})
});
})
I'm not sure if it's possible to enforce.
If it is, try adding this in the head-tag:
<script type="text/javascript">
if(document.images)
(new Image()).src="http://www.image.com/example.png";
</script>
In theory that may load and cache that image before anything else.
I think if you place the IMG tag at the top of your html body it will be loaded first. If you do not want to move your div just use a copy of the image tag. Once the images is loaded it will be shown in every image tag which shows the same picture.
Or you could use spin.js as loading image. It display this "loading cycle image" via javascript.
Check it out under:

I'm loading image tags via AJAX and inserting them with the conventional .html(content) function in jQuery alongside a bunch of other HTML. However, this question still applies if you're loading a page from scratch. Now, I have a background image placeholder to be put there while the image loads. I want this background image to go away when the image loads.
Problem:
If I attach a conventional .load(function) event listener, I am concerned that the image might load before the hook is applied (putting the hook in a small JS <script> right after the image instead of in a $(function(){}) block might help a bit). I have yet to encounter such behaviour, but I know of nothing in the specification that prevents this from happening (since the image tag ought to be fully parsed before the hook is applied).
My current solution. Put the command in an inline onload= property within the image tag.
Is there a better way?
Up until a week or so ago I would have been lost too. Thankfully this answer to another question will help you out:
Basically put this in $():
$(function(){
var img = $("#idofimage").load(function () {
/* your magic to swap out placeholder */
});
if (img[0].complete) {
// Trigger the load handler if the image
// is already loaded
img.trigger('load');
}
});
You don't need jQuery for this, you can do it with CSS.
.my-img-loader-class { background:url('placeholder-or-progress'); }
Or if you don't want to change your HTML:
#container img { background:url('placeholder-or-progress'); }
To show placeholders while images are loading in a specific div.
The way it works is the image element will show the placeholder image as its background, and when the src loads it will appear above the placeholder, so as to replace it nicely.
