I'm working on an image slideshow that allows users to cycle through a set of images in semi-fullscreen. Here's a development version of it: [link removed, was only temp link] There are several ways to progress to the next image: by clicking the large image, by picking a specific thumb, by using the arrow icons or even your keyboard arrows. All of these basically call a js function loadImage with the correct params: function loadImage(id,url) { // general image loading routine // enable loader indicator $("#loading").toggle(); var imagePreloader = new Image(); imagePreloader.src = url; loading

How to show page preloader only once while entering through domain name?

由 ﹥＞﹥吖頭↗ 提交于 2019-12-05 00:41:35
问题 So, I have jQuery page preloader on main page like this: <script type="text/javascript"> $(window).load(function() { $("#preloader").delay(700).fadeOut("slow"); }) <div id="preloader" class="preloader"></div> This shows 4 times: When I enter the site through domain name; When I refresh main page by F5; When I click on logo (i must go to main page when i clicked that); When I click «Home» menu item. But i want to show it only on first two times. So, the first idea which came in my mind is

Angular 2+ Application pre loader with percentage indicator

由 这一生的挚爱 提交于 2019-12-04 12:21:07
问题 Does anyone know the good solution for implementing Angular 2+ pre loader with percentage indicator ( Similar to Gmail's loading screen )? I know that usual way is to add <div> inside our <app-root> and style it, maybe even add CSS animations and it will be replaced by app content once app is loaded. But... What I am actually looking is to display animated splash screen ( SVG or whatever else ) where after animation completes loading bar should appear and show progress status. At first point

Bytes received and bytes total of images via Javascript/jQuery

由 二次信任 提交于 2019-12-04 07:47:53
I'm working on a Javascript/jQuery powered image preloader, and have hit a bit of a snag. While as of currently it provides the progress based on loaded_images / total_images , this is not very accurate given a page could have a thousand 1kB images, and a single 1MB image. I'm looking for a way to incorporate filesize into the progress calculations. Now, I've looked into some (cross browser compatible) tricks at capturing the filesize of a given image, and it seems that Ajax requests for Content-Length were the most reliable (in terms of accuracy) like so: var imageSizeTotal = 0; var

javascript preloader/progress/percentage

由 Deadly 提交于 2019-12-03 00:19:13
I'm having trouble finding any good information on how to make a javascript(or jquery) progress bar WITH text that tells you the percentage. I don't want a plug in, I just want to know how it works so that I can adapt it to what I need. How do you preload images and get a variable for the number of images that are preloaded. Also, how do you change html/css and-or call a function, based on the number of images that are loaded already? <img> elements have an onload event that fires once the image has fully loaded. Therefore, in js you can keep track of the number of images that have loaded vs

How to set preload scope for Rails Associations::Preloader?

由 风格不统一 提交于 2019-12-01 02:11:21
问题 I need to preload associations of the model with complex conditions. NO, includes doesn't work for me. It generate wrong SQL for my task.

What is preload_scope in this case? And how I can use it for filtering

How does the javascript preloading work?

由 試著忘記壹切 提交于 2019-11-30 09:52:54
I don't want to know a way to preload images, I found much on the net, but I want to know how it works. How is javascript able to preload images? I mean, I tried a snippet from here, and even if it works, it doesn't seem to preload images. When I check firebug, I can see that the image is loaded twice, once while the preloading, another time when displaying it! To improve this code I'd like to know how it works. Here is what i do: function preload(arrayOfImages) { $(arrayOfImages).each(function(){ $('<img/>')[0].src = this; //(new Image()).src = this; alert(this +' && ' + i++); }); } then i do

Java 9 JavaFX Preloader

由 不羁的心 提交于 2019-11-30 09:44:05
In Java 8 I can launch a JavaFX application with a preloader using the following method: LauncherImpl.launchApplication(WindowMain.class, WindowMainPreloader.class, new String[]{...}); I prefer to start it from code, like above, instead of using a deploy configuration, because I don't want the graphical interface to start every time I start the application, but only after some code that has computed that the application should run in GUI mode. I was using the class "com.sun.javafx.application.LauncherImpl", but apparently in Java 9 all classes starting with "com.sun" are removed. So, how can I

Is it possible to preload page contents with ajax/jquery technique?

由 北战南征 提交于 2019-11-30 06:46:27
问题 Is it possible to preload all page contents (like showing a loading bar / animated gif.. or loading text.. ) until the contents are fully loaded and then displayed to the user/visitor ? If this is possible, can you give me just directions or resources to follow to achieve this. Because I was able to find image preloaders easily, but I am seeking for a preloading technique that will preload all content on the page before being displayed. 回答1: There's no need to use Ajax for this. Simply set
