元气小坏坏 提交于 2019-11-26 10:32:00
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(){ $("

Java - Loading dlls by a relative path and hide them inside a jar

为君一笑 提交于 2019-11-26 08:23:06
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

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.

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.

jQuery Ajax wait until all images are loaded

与世无争的帅哥 提交于 2019-11-26 05:25:41
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.

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
