Single Image Jquery Preloader

由 巧了我就是萌 提交于 2019-12-11 04:46:10
问题 I am using a fairly large background image on a website I am developing. Currently, the background color loads, and when the image is done loading, it then loads. That is perfectly fine; however, I am trying to achieve an effect where a preloader gif spins until the background image loads, and then fades in. Currently here is my Jquery (which isnt working at all) $(document).ready(function(){ $('span.loader').show(); $("body").css('background-image','url(images/bg.jpg)').ready(function(){ $(

How can I preload textures with Three.js?

由 孤人 提交于 2019-12-11 01:36:42
问题 I am using THREE.TextureLoader() to preload the textures, but I can't seem to assign them to my shaders. var textureLoader = new THREE.TextureLoader(); textureLoader.load('img/texture.jpg', function(){ assetsLoadedCount++; }); In another function, I check assetsLoaded to initialize my scene: if(assetsLoadedCount == totalAssetsCount) { // Create a sphere: var sphere = new THREE.Mesh( new THREE.SphereGeometry(100, 10, 10), new THREE.MeshBasicMaterial({ map: textureLoader }) ); scene.add(sphere)

Preloading of html web page or non-flash web applications?

由 ∥☆過路亽．° 提交于 2019-12-10 16:47:20
问题 I believe that most of you have heard of preloading of images. But is there anyone who knows how we can preload webpages? For instance, when we are login to GMAIL, we will see a loading progress bar. How do we preload html webpages/web applications (non-flash based ) as per what gmail is doing? best Regards 回答1: Due to the stateless nature of the HTTP protocol, pre-loading webpages could be challenging. One way to achieve this would be to have a minimal HTML sent to the client initially and

问题 Chrome's new version added support for <link rel="preload"> . They have posted a lot of info with references to the original documentation. Can someone provide simple explanation on how it works and what is the difference compared to the case without rel="preload" . 回答1: In it's most basic form it sets the link that has rel="preload" to a high priority, Unlike prefetching, which the browser can decide whether it's a good idea or not, preload will force the browser to do so. === A more in

HTML5 Video - Suspend Loading / Partial Load

由 馋奶兔 提交于 2019-12-08 01:38:38
问题 Is there a way to preload a portion of a video, but not the entire thing? I noticed that there is a "suspend" event that indicates the video is expectedly not downloading until further instruction, but I'm unsure of how to trigger this event? My goal is to preload a portion of a video without taking up all the users' bandwidth. Thanks! 回答1: You can pre-fetch any URL with XHR, but you can't control how much it pre-fetch from the client-side. I think you can try this: set a header in the XHR

Getting an image's original width and height in jQuery

由 心已入冬 提交于 2019-12-06 22:08:15
问题 I need to get the original width and height of an image given a specific source. My current method is: img.tag = "<img style='display:none;' src='" + img.src + "' />"; img.Owidth = 0; img.Oheight = 0; $(img.tag).load(function() { img.Owidth = $(this).width(); img.Oheight = $(this).height(); }).appendTo(img.parent()); With Owidth and Oheight being the original dimensions of the loaded image. I'm wondering if there is a better way to do this given that: The image could either already be loaded,

How to preload images for Foundation's Orbit image slider?

由 落花浮王杯 提交于 2019-12-03 14:19:47
Using Zurb's Foundation 4.1.5 (latest version), the Orbit image slider works great. Unfortunately it looks really for the first couple of seconds where all the images appear as a giant bulleted list. Then the JavaScript kicks in and it all is beautiful. How do I avoid the initial ugliness? Can I preload the images? Can I have everything with display: none or visibility: hidden until it's ready? Per Foundation documentation We've cleaned up how Orbit initializes by adding a wrapper feature that stops the ugly flash of unstyled content. Here's the markup needed: To add the preloader, simply
