image-preloader

问题 I've used examples from various other Stack Overflow questions and for some reason this is not working for me. I made a function to get thumbnail images and return either the actual image path or the path to the default (no thumbnail) image. Using both the JQuery approach as well as the Javascript Image class, I get 404 errors regarding missing images in console and the found images don't error but don't show up. Can anyone perhaps point out what I am doing incorrect? In the getThumbnail()

问题 Current I have this code: var imgCount = 36; var container = $('#3D-spin'); var loaded = 0; function onLoad() { alert(loaded); loaded++; if(loaded >= imgCount) { alert('yay'); } } for(var i = imgCount-1; i >= 0; i--) { container.prepend( $('<img>') .one('load', onLoad) .attr('alt', 'View from '+(i*360/imgCount)+'\u00B0') .attr('src', '/images/3d-spin/robot ('+i+').jpg') ); } However, it's behaving VERY strangely. Normally, I get no alert boxes. However, if I open developer tools, and pause

问题 On a page, there is a button. When the button is clicked, a dropdown shows up. The dropdown contains an image. The problem is that the image is not fetched until the user clicks the button. $("#my_button").click(function(){ $("#my_dropdown").html("<img src=\"http://mysite.com/image.jpg\" />"); }); I'd like to fetch the image when the page loads so it's ready to go when the user clicks the dropdown. How can I do this? I was thinking I could insert the image into the page with display:none set,

问题 I was wondering, is there a way to detect if a certain image / div is loaded? For example when i am loading two heavy images and showing a loading sign at the two places the images will later occupy, is there a way to already display the first image when it's loaded while still loading the second one? 回答1: myImage.addEventListener('load', function() { ... }, false); Code inside the above function will be called when the image is finished loading. 回答2: If you are using new Image to preload

问题 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? 回答1: Per Foundation documentation We've cleaned up how Orbit initializes by adding a wrapper

问题 I'm trying to preload about 150 images and I want to be able to be able to do two things... 1) The images are being preloaded using a list of file names. Not every single file name in the list has a file to match up to it. eg) pic04.jpg may not exist, even if it is in the list. So when I'm preloading, i would like to be able to figure out whether or not the image exists, if possible. 2) Right now the function is simply preloading all 150 images using pictures[i] = new Image(); pictures[i].src

问题 I have a problem with my responsive flexslider plugin. The plugin works fine unless you have many images in the actual slideshow. The loading behavior is then just not acceptable. I was hoping someone can help me with the following flexslider image preloader script since I can't get it to work. Here is the code I'm using: FLEXSLIDER HTML <div class="slider"> <div class="flexslider loading" style="overflow-x: hidden; overflow-y: hidden; "> <ul class="slides" style="width: 5200%; -webkit

问题 I would like to preload the next image in a Fancybox2 gallery, but I don't know if that's possible. I know how to preload and image by creating a new Image() object and setting the src attribute, but I don't know which Fancybox callback should I use. Does anyone know which Fancybox event is triggered when it starts or it finishes displaying the current image? So the answer is: simply use 2.0.5 and above to take advantage of the preload setting, which preloads 3 images by default. 回答1:
