How to catch error in jQuery's load() method

阅读更多关于 How to catch error in jQuery's load() method

问题 I'm using jQuery's .load() method to retrieve some data when a user clicks on a button. After the load successfully finishes, I show the result in a <div> . The problem is, sometimes an error occurs in load() while retrieving the data. How can I catch an error in load() ? 回答1: load() documentation. Just a little background on how a load error happens... $("body").load("/someotherpath/feedsx.pxhp", {limit: 25}, function (responseText, textStatus, req) { if (textStatus == "error") { return "oh

i have trouble loading an xml file from assets directory. using the same line of code (just changing the path) i get different results ( either ok or NPE / file corrupted ) the file "castle1.tmx" (it's an xml file) is copied in two locations: res/xml/castle1.tmx assets/level/castle1.tmx with this line, it works: XmlResourceParser xrp = ctx.getAssets().openXmlResourceParser("res/xml/castle1.tmx"); while with this line it doesn't: XmlResourceParser xrp = ctx.getAssets().openXmlResourceParser("assets/level/castle1.tmx"); i get the following result: 04-05 21:46:40.940: WARN/ResourceType(29056):

jQuery .load() not firing on images (probably caching?)

阅读更多关于 jQuery .load() not firing on images (probably caching?)

问题 I have some pretty basic jQuery code: ... $(this).find('img').load(function(){ loadedImages++; if(loadedImages == $this.find('img').length){ ... However, thats not firing consistently. It fires if i do a hard refresh or close my browser, but a normal refresh, or just hitting the same URL twice at any time without erasing the cache makes the .load() never fire. Any ideas on how to fix this? 回答1: A way would be to add a "dummy variable" at the end of the URL that you use to grab the image...

Jquery load() and PHP variables

阅读更多关于 Jquery load() and PHP variables

If I load a PHP page with Jquery .load(file.php), can the included file use the php variables that were defined on the page that called the load()? You're misunderstanding how things work. PHP runs before any browser response is issued to the client, and all code runs on the server . The variables declared in your PHP file are destroyed after all the PHP code has been run; they "vanish." JavaScript runs after the browser response has begun, and all code runs on the client . By "loading" the output result of the PHP file, you won't get any access to PHP's variables, only the output. If you want

阅读更多关于 Scala - Dynamic object/class loading

问题 In Java, I load external class (in .jar file) by this way: ClassLoader classLoader = new URLClassLoader(new URL[] { new File("module.jar").toURI().toURL()}); Class clazz = classLoader.loadClass("my.class.name"); Object instance = clazz.newInstance(); //check and cast to an interface, then use it if (instance instanceof MyInterface) ... And it works fine. ==================== Now I want to do the same thing in Scala. I have a trait named Module ( Module.scala ): trait Module { def name: String

Extremely slow model load with keras

阅读更多关于 Extremely slow model load with keras

问题 I have a set of Keras models (30) that I trained and saved using: model.save('model{0}.h5'.format(n_model)) When I try to load them, using load_model , the time required for each model is quite large and incremental. The loading is done as: models = {} for i in range(30): start = time.time() models[i] = load_model('model{0}.h5'.format(ix)) end = time.time() print "Model {0}: seconds {1}".format(ix, end - start) And the output is: ... Model 9: seconds 7.38966012001 Model 10: seconds 9

How can I use jQuery “load” to perform a GET request with extra parameters?

阅读更多关于 How can I use jQuery “load” to perform a GET request with extra parameters?

问题 I'm reading the jQuery load documentation and it mentions that I can use load to perform a GET request by passing in extra parameters as a string. My current code with my parameters as key/value pair is: $("#output").load( "server_output.html", { year: 2009, country: "Canada" } ); The above works fine but it's a post request. How can I modify the above to perform a GET request while still using load ? 回答1: According to the documentation you linked: A GET request will be performed by default -

How do I create a progress bar for data loading in R?

阅读更多关于 How do I create a progress bar for data loading in R?

问题 Is it possible to create a progress bar for data loaded into R using load()? For a data analysis project large matrices are being loaded in R from .RData files, which take several minutes to load. I would like to have a progress bar to monitor how much longer it will be before the data is loaded. R already has nice progress bar functionality integrated, but load() has no hooks for monitoring how much data has been read. If I can't use load directly, is there an indirect way I can create such

How to use dylib in Mac OS X (C++)

阅读更多关于 How to use dylib in Mac OS X (C++)

I made an application (an executable) calling some dylib successfully, However, the dylib files and the executable are in different directory. I added the directory contains dylib files to the $PATH environment variable, however, it still doesn't load. I copy all the dylib files to the executable, the program finally runs. This confirms the dylib files have no problem. However, How can I tell the OS to find it? In windows, I just need to add the directory path contains dll files to $PATH. What do I need to do for Mac OS X? Thanks a lot! After reading the link that Justin provided, I was
