问题 I m working with a legacy spring 2.0.6 project integrated with jersey 2.x. The application context contains some beans like: <!-- - Application context definition --> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema

问题 I have lot of problems with a function and I get confused with the variable scope. I tried with a callback function, but I cannot get it. I have a function to animate a background with css. I need that function doesn't restart the incrementer variable to 0 when I click for a second time while a setInterval is running. See that when you click a twice in time1 or time2 of html, the order of counter doesn't hold the order. function movie(elm,jumpPx,spriteHeight,duration){ var inc=0; var time

问题 This question already has answers here : JavaScript closure inside loops – simple practical example (44 answers) Closed 4 years ago . Using CreateJS, I have output a canvas with instances of various objects, animating in various ways. Almost all is working ok, except for one issue, which I think is a scope issue, but I'm not sure how to fix. I have an instance referenced by '_pulsars', containing 11 instances of an object 'pulsar', and code runs like this: function attachPulseFuncs() { var

问题 In my AngularJS app, I have three controllers. One is the main controller and the other two are siblings. I have Sibling control 1 to emit data to Main control , which broadcasts the data, which sibling control 2 then picks up. Sibling control 1 $scope.selectedPatentFx; $scope.$watch('selectedPatentFx', function(newValue, oldValue){ if($scope.selectedPatentFx) { $scope.$emit('calculateFx', {patentfx: newValue}); } }) Main control $scope.$on('calculateFx', function(event, obj){ $scope.

问题 When you create a new repl instance in code it automatically has access to anything in global scope. You can modify the repl context to expose some custom variables in local scope so that the repl can access them, but I don't see an easy way to eliminate access to the global scope. I wish I could just give the repl a new blank global scope. Here is an example repl instance: var repl = require('repl'), msg = "Hello world!"; repl.start('> ').context.msg = msg; In that repl I typed out the

问题 I've been reading this Ruby book, then there's this example that I haven't well understood : CONST = "outer" module Mod CONST = 1 def Mod.method1 # module method CONST + 1 end end module Mod::Inner def (Mod::Inner).method2 CONST + " scope" end end Mod::CONST # => 1 Mod.method1 # => 2 Mod::Inner::method2 # => "outer scope" Would you please explain this to me (a detailed explanation) so I can fully understand how the scope works in Ruby. Thank you. 回答1: Constants in Ruby (identifiers beginning

问题 Please can any one advise me if there is an object in .net that can be used to get a list or references to all objects that are currently in scope for an object. For example if the code is currently executing in a method, what objects declared in this method are currently instanciated and alive and what objects that are declared at class level have been instanciated already and are alive? Also I know I can test each object declared explicitly for a null reference, but I am looking for

问题 I followed the instructions on docs.angularjs.org to test a controller with karma and it's perfectly working. However I was wondering if it's possible to test a controller which is not using $scope? Testing this controller is ok: angular.module('starter.controllers') .controller('PasswordController', function PasswordController($scope) { $scope.password = ''; $scope.grade = function() { var size = $scope.password.length; if (size > 8) { $scope.strength = 'strong'; } else if (size > 3) {

问题 I have configured ninject in wep api as below. I have created two kernel objects, one in request scope and another in thread scope: var requestKernel = new StandardKernel(); requestKernel.Bind<IGlobalDbContext>().ToConstructor(ctx => new GlobalDbContext(Configuration.GlobalDbContext)).InRequestScope(); var threadKernel = new StandardKernel(); RegisterServices(threadKernel); threadKernel.Bind<IGlobalDbContext>().ToConstructor(ctx => new GlobalDbContext(Configuration.GlobalDbContext))

问题 Working with an api and I need to one of the first responses alongside with the second response in order to serve up a new page. The problem I'm facing is that my variable $x is always set to whatever the last # is in the loop, ie 103 in this specific case. Here is my code: $.ajax({ dataType: 'text', type: 'post', url: 'getAllMessages.php', success: function(responseData) { var newString = responseData; var newerString = newString.substring(0, newString.length - 1); $newObject = jQuery
