loading

问题 Anyone have a good way to load a JS file but cancel loading it if it takes too long? I'm thinking something like this, hypothetically: <script type="text/javascript" cancel_after="2000" src="myfile.js"></script> The script is code that needs to get loaded in the head, because it replaces elements on the page, and so the browser needs to block while loading it. But in case the server takes too long to respond, I'd like to be able to have the browser proceed without loading the script. 回答1: Use

问题 I have created a GUI using Tkinter. The GUI is supposed to open a file and read the content. However, if the file content is really big and if certain task takes up a lot of time, it would require a loading screen to let user know it is loading. This loading screen should also get all the focus and not allow user to click on anything else on the GUI until task is complete. How can I do this? The following is a simple example of my code. It would be great if I can get a modified version of the

问题 I have a viewController with a webView where I am displaying a local html file. The problem is that it takes some seconds before loading therefore I am trying to avoid this waiting time. The best way I thought so far is the following: as soon as I get into the main page I will start to load the file into the webView, in this way when I will get into the infoViewController with the webView it will be already loaded. Here is the code: //mainViewController.m: tempInfo = [[InfoViewController

问题 I am trying to implement a loading screen in swift, that I can reuse from any class in the project (I have a few classes that will handle 'long running' activities) The public function is, from another answer: public class LoadingOverlay{ var overlayView = UIView() var activityIndicator = UIActivityIndicatorView() class var shared: LoadingOverlay { struct Static { static let instance: LoadingOverlay = LoadingOverlay() } return Static.instance } public func showOverlay(view: UIView) {

问题 My target: We are allowing to integrate our product with third party components (libraries) which are not installed as part of our product because of licensing. At the moment we want to load features related to third party components only if these components are installed on the client's machine. Current solution: I'm using Assembly.ReflectionOnlyLoad with providing full names of third party assemblies to validate installation of third party components before the application loads related

问题 I have to make a project for work using HTML5/CSS3/JavaScript, and using XML as the dataprovider. The requirements state that it has to be compatible with Internet Explorer, Firefox, Safari and Chrome. I'm developing in Firefox, so that works just fine. Safari works like a treat as well, and luckily it works perfect in the new IE9. I'm only having problems getting it to run in Chrome. As Chrome seems to support a lot of the new HTML5/CSS3 features, it shouldn't be too much work to get it

One thing I noticed is that the framework does not seem to have a way to mock XHR requests. So I decided to use sinon for the mocking. Heres my question, I cannot successfully load the sinon code into my dojo module. Here is what I tried: define(["doh/runner", "tests/sinon-1.4.2"], function(doh, sinnon) { ... }); I have the tests package

问题 I have read a few articles online about optimizing javascript loading. A few key points I got is to minimize the number of script files (http requests), minify and enable gzip on the server. Currently, what is done on my side is that all javascript files are minified, and gzip can be simply enabled as well. Part 1) My problem is that I have around 20 javascript files, there is one common.js that has all the core functions. Besides that, every page would load at least one other file that
