jQuery.lazyload to work with printing

阅读更多关于 jQuery.lazyload to work with printing

问题 Trying to get jquery.lazyload to work for printing and the print media query. It almost kind of works in Chromium. However, it will only display on 'screen' and not in the 'print' output. Not sure if this is due to the async nature of lazyload or my misuse. Here's what I've got so far: $(document).ready(function() { if (Modernizr.mq('only all')) { // check of mq support print_mq = window.matchMedia('print') print_mq.addListener(function(mql) { if (mql.matches) { $("img.lazy").trigger('appear'

I have some images on my page: <img src="http://www.abc/images/abc.jpg" /> If the image can't be loaded (because abc.jpg doesn't exist, for example), then I show a "default" image instead: <img src="http://www.abc/images/abc.jpg" onerror="this.src='http://www.abc/images/default.jpg'" /> If I add LazyLoad to my image and load an even more lightweight default image, it becomes: <img class="lazy" data-original="http://www.abc/images/abc.jpg" src="http://www.abc/images/graydefault.jpg" onerror="this.src='http://www.abc/images/default.jpg'" /> Now, when the page loads, it will first load the

问题 I have images that need to be absolutely positioned so that the center of the image is in the center of its parent div. I already have code that does this. I recently added the Lazy Load plugin and it works as expected. But I need a way of triggering my image centering code after lazy load has loaded and faded-in the image. My current code is basically this: jQuery(document).ready( function($) { // Make all lazy images ready to load themselves and listen for a custom event $("img.lazy")

Is there a way to combine the lazyload js library with Picturefill?

阅读更多关于 Is there a way to combine the lazyload js library with Picturefill?

问题 I'm wondering how you would incorporate lazyload.js with Picturefill, when lazyload's image syntax requires the img tag along with data-original, and Picturefill's syntax doesn't have a spot for those. For example, this is my markup for an image using Picturefill: <span data-picture data-alt="Operating room 2 stands vacant in Dr. Tariq Mahmood's closed Renaissance Hospital in Terrell, Texas."> <span data-src="img/main1_small.jpg"></span> <span data-src="img/main1_small_x2.jpg" data-media="

问题 PLUGIN I am using a jQuery plugi called lazyload. What this does is lazy load images - meaning it does not render them in the browser until the image is within the scope of the viewport. This is useful when you have a page that has many images, for example, and you don't want it to spend forever with the initial load. FIREFOX Ok, so I am also using Firefox version 23.0.1 PROBLEM The plug in is great, however when scrolling down after some images I start getting errors where the image doesn't

问题 With the datatables javascript plugin I want to display 10k little images in a table with pagination. Because I load too much of them, I get errors. I would like to load those images only when they appear so I found the lazyload plugin. However, the images don't appear at all at first. I have to manually enter $("img.lazy").lazyload(); in the browser console. Then only it loads the images that are on screen (i.e. when I scroll down, I see all other images unloaded). This proves at least that
