Can i use HtmlUnit to listen for resource loading events?

由 时间秒杀一切 提交于 2020-01-05 03:00:08
问题 I'm trying to use HtmlUnit to detect resources (scripts, images, stylesheets, etc) that fail to load on a webpage. I've tried new WebConnectionWrapper(webClient) { @Override public WebResponse getResponse(WebRequest request) throws IOException { WebResponse response; response = super.getResponse(request); System.out.println(response.getStatusCode()); return response; } }; to no avail. It doesn't seem to handle CSS, images or JS, despite HtmlUnit logging: statusCode=[404] contentType=[text

Jquery loading screen to cover a large mysql query via PHP?

由 僤鯓⒐⒋嵵緔 提交于 2020-01-04 02:27:06
问题 I'm in the middle of a reporting tool for my client which basically rebuilds reports on the fly if they are X days old. The issue is that the reports are rebuilt with PHP, and some of them can be pretty big, meaning 20-40 second loading times. At the moment, it just hangs the page while it performs the query. What I'm wanting to do however is have some sort of jquery loading overlay placed into the page before the query starts, and then when the query finishes, redirect to another page (where

Model View Presenter - Passive View - Who loads the Model?

问题 I'm curious in using the MVP Pattern to improve testability. I have experience with MVC but MVP seems different. I'm having an application that operates on a 'project' file which is in fact an compressed archive of several files and folders. This project should be my model. Where will I put the code that loads the model? I'm also thinking about another abstraction layer: Some kind of BackEndConnection. It will be able to read a project file. It can be an FileBackEndConnection or an

Browser continues 'loading' after ajax request finishes

由 泪湿孤枕 提交于 2020-01-03 19:01:31
问题 You've seen this - on an ajax-heavy page, like meebo.com, the browser never stops 'spinning', it never indicates that it's finished loading. What causes this, and is there any way to consistently tell the browser (whatever browser it may be), that loading has completed? EDIT: Sorry, I should've specified that I'm a developer here. I've noticed this on other sites, and now one of mine as well that's using ajax. I want to make sure that when an ajax call comes back, the page stops 'loading'.

Is rootViewController always ready to present a segue by the time application:didBecomeActive is called (iOS)?

由 放肆的年华 提交于 2020-01-03 05:38:20
问题 My app has a rootViewController setup in a storyboard. I originally asked this question, but I can see that it is the wrong question to ask now: Is the viewDidLoad method of the rootViewController always called before application:didBecomeActive in the app delegate? Does that viewDidLoad method always finish before application:didBecomeActive is called, or can the two run concurrently? I can run tests, but I know that these tests don't take into account every situation. I want to understand
