loading

问题 I did a Google search and I cannot find a way to do a loading with percentage. Anyone know how I can find an example of that? I need a preload for a website from 0-100 without bar, before show the content, but I cannot find any example. 回答1: If you mean you want to show the content only when it is fully loaded, you may try following two options: 1) wrap all content inside a <div id="wrapper" style="display:none;"></div> tag and on load complete event show it like this: $(function(){ $("

问题 PART 1 I am developing a Java application that should be release as a jar. This program depends on C++ external libraries called by JNI. To load them, I use the method System.load with an absolute path and this works fine. However, I really want to \"hide\" them inside the JAR, so I have created a package to collect them. This forces me to load an relative path - the package path. By this approach, I let the user run the JAR in any directory, without being worried about linking the DLLs or

问题 When using Comet, or Ajax Long Pull techniques - an iframe is usually used. And while that iframe is waiting for the long connection to close, the browser is spinning its throbber (the progress/loading indicator). Some websites, for example etherpad.com, managed to make it stop. How do they do it? 回答1: After digging for a day and a night in the guts of the internets, here is what I came up with: server-sent events - Very cool, currently works only in Opera, but may be part of HTML5 and other

问题 How should I load files into my Java application? 回答1: The short answer Use one of these two methods: Class.getResource(String) Class.getResourceAsStream(String) For example: InputStream inputStream = YourClass.class.getResourceAsStream("image.jpg"); -- The long answer Typically, one would not want to load files using absolute paths. For example, don’t do this if you can help it: File file = new File("C:\\Users\\Joe\\image.jpg"); This technique is not recommended for at least two reasons.

问题 I\'m trying to perform an Ajax call with jQuery which is working well. I use the success event to display the data. It seems however that success gets triggered as soon as the external HTML file gets loaded. If there are large images they keep loading after they\'re shown. Is there a way to display the content after everything is fully loaded? Here is the code: $(\'#divajax\').html(\'<br><div style=\"text-align: center;\"><img src=\"res/ajax-loader.gif\"></div>\'); $.ajax({ cache: false, url:

问题 Could you suggest me a way for loading packages in R automatically? I mean, I want to start a session in R without needing to use library(\'package name\') several times. Suppose I downloaded all packages I\'ll want to use the next time I start R. 回答1: Put library(foo) in your .Rprofile file or set R_DEFAULT_PACKAGES : see ?Rprofile ... In particular (because ?Rprofile is long and potentially intimidating): If you want a different set of packages than the default ones when you start, insert a

If not, is there a way to do it at all? 回答1: .complete + callback This is a standards compliant method without extra dependencies, and waits no longer than necessary: var img = document.querySelector('img') function loaded() { alert('loaded') } if (img.complete) { loaded() } else { img.addEventListener('load', loaded) img.addEventListener('error', function() { alert('error') }) } Source: http://www

问题 I\'ve a data table as below: <h:dataTable value=\"#{bean.items}\" var=\"item\"> I\'d like to populate it with a collection from the database obtained from a service method so that it is immediately presented when the page is opened during an initial (GET) request. When should I call the service method? And why? Call it before page is loaded. But how? Call it during page load. How? Call it in the getter method. But it is called multiple times. Something else? 回答1: Do it in bean's
