问题 I'd like to define a module which computes a new dependancy, fetches it and then returns the result. Like so: define(['defaults', 'get_config_name'], function(defaults, get_config_name) { var name = get_config_name(); var config; require.synchronous([configs / '+name'], function(a) { config = defaults.extend(a); }); return config; }); Is there a way to do this or a better way to attack this problem? 回答1: You may try to use synchronous RequireJS call require('configs/'+get_config_name()) , but

问题 I am trying to execute a Bash Shell script from Java and it runs fine using this piece of code. public void executeScript() { try { new ProcessBuilder("myscript.sh").start(); System.out.println("Script executed successfully"); } catch (IOException e) { e.printStackTrace(); } } The above code runs fine asynchronously. But what I would like to achieve is to execute the code synchronously. I would like the Java process to wait until the execution of the script is completed and then execute the

问题 What's the best way to make a synchronous version of an asynchronous method in Java? Say you have a class with these two methods: asyncDoSomething(); // Starts an asynchronous task onFinishDoSomething(); // Called when the task is finished How would you implement a synchronous doSomething() that does not return until the task is finished? 回答1: Have a look at CountDownLatch. You can emulate the desired synchronous behaviour with something like this: private CountDownLatch doneSignal = new

问题 Can I make use of jQuery AJAX API and make a synchronous calls? 回答1: Like Obama would say: YES YOU CAN ! jQuery .ajax() Setting async = false within the .ajax() handler will do the trick. 回答2: While jQuery can make sync AJAX calls by setting the synch:false property, this causes the browser to hang until the AJAX completes. Using a flow control library like Frame.js enables you to make synchronous calls without tying up the browser: $.each(ajaxObjects, function(i, ajaxCall){ Frame(function

问题 I have a Node.js/Express app that queries a MySQL db within the route and displays the result to the user. My problem is how do I run the queries and block until both queries are done before redirecting the user to the page they requested? In my example I have 2 queries that need to finish before I render the page. I can get the queries to run synchronously if i nest query 2 inside the 'result' callback of query 1. This however will become very convoluted when the number of queries increase.

问题 I want to run a function on click that runs multiple other javascript functions. It works, but only for the first few functions called. More Detail: I am trying to filter a grid. The "savedSearch" function is called by a button that will then search multiple fields according to your saved search criteria (i.e. filter column A for "Monday", which is in the Model). Each "sub-function" (the "appliedSearch" functions) applies to a different field. The first few usually work (I've tried formatting
