Javascript: Detect when a window is fully loaded

阅读更多关于 Javascript: Detect when a window is fully loaded

问题 I have a script which may be loaded at any stage of the life cycle of a web page. When the script is loaded it must run an initialize() method. I want this function to be run on the "onload" event, but I cannot be certain that the page has not already loaded, i.e. that the "onload" has not been fired already. Ideally my script would look like this: var _initialize = function() { ...}; if(window.LOADED) _initialize(); else if (window.addEventListener) window.addEventListener('load',

阅读更多关于 How do Python modules work

问题 I was wondering how do Python modules work? Say I want to make my Python program some custom modules to package with it, where would I put them in relation to the main .py file?(and how would I load them if not using the usual way) 回答1: If the module is specific to your program, you can put into the same directory as the main script.

问题 Hiho Community, i try to show a splashscreen if my videosphere loads. I use this code -> set a loading animation with a-frame for loading a splash before the scene and it works perfect, but i need to let my videos have the attribute preload so if i start them they need some time to load too and there should the splashscreen pops up again. Some ideas (maybe a second listener which says: show splashscreen if video loading)?. HTML: <body> <div id="splash"> <div class="loading"></div> </div> <a

阅读更多关于 Faking a load more with jQuery (no AJAX/PHP)

问题 I have a list of data on a page, a simple ordered list of around 100 items, just a title and excerpt like on an archive page. On page load, I want to hide all but the first 25 items with an option to load 25 more, 25 more until they're all visible. I've looked into simple pagination plugins like jPaginate but would simply like the list to expand by 25 every time.

问题 This helpful idea from Andy Gaskell supports 50% of my next question: I'd like to load posts dynamically with WordPress. Fetching them with Andy's function does work, but How do I bind the load to each and every one of the posts? Can I insert PHP generated content (post permalink, for example) to the JS script?
