问题 I know this must be really basic stuff but I don’t understand how the scope is working. I want the closed variable be known in the entire JavaScript file. I have something like that (in jQuery): var closed = 0; $(function(){ console.log(closed); }); But closed is getting logged as false . I tried many things with load and onload functions, but I failed. 回答1: Use let instead of var as closed is a global variable used by JavaScript runtime so to make it local to the scope of the code you can

问题 I'm new to Meteor and I don't quite get the whether my variables will be available to the client or server or both. var variable_1 = []; if (Meteor.isClient) { var variable_2 = []; } if (Meteor.isServer) { var variable_3 = []; } In this example if I use Meteor.method in the server side on variable_1, will I be able to access whatever I just did to variable_1 from client? Can I access variable_2 with a method in Meter.isServer? What is the difference between the scope of variable_1 and

问题 I have a directive that is depended on a controller which gets data from an api though Ajax call. It works correctly. I am trying to test it using jasmine and the strange issue is that when I debug the code and check for a value of let's say $scope.measurement it returns true, but when I run in the terminal it can't find $scope.measurement and raises an error Expected undefined to be true . no clue what can be the issue. I thought the problem might be with an isolated scope, but the element

问题 So I'm trying to change the value of a minimum and maximum guess (with the actual guess being made by a random number generator) in order to stop the program from guessing the same number twice. I have a method that makes a guess but also tries to set a lowest and highest guess which then changes when the method is used again public static int takestab (int low, int high) { int estimate; estimate = (low + (int)(Math.random() * ((high - low) + low))); if (estimate < number) { lowestguess =

问题 I need to create an session scope variable exactly when a session is created, before any task is execute (because all my tasks need an init session scope variable to run). Because, session instance of HttpSession is automatically create by grails application when a session is created. Developer want to use session for store session variables just use 'session' instance. I can not find out where init session variable will be put. Hope that someone will help me.

问题 I have a private function Load which creates a list, creates several objects and then binds a datagrid to the list. The code is similar to: List<Car> cars = new List<Car>(); cars.Add(new Car("Ford", "Mustang", 1967)); cars.Add(new Car("Shelby AC", "Cobra", 1965)); cars.Add(new Car("Chevrolet", "Corvette Sting Ray", 1965)); _dgCars.DataSource = cars; Now I would like to loop through the values in another private function. I tried something similar to: foreach (Car car in cars) // Loop through

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 5 years ago . I am starting to be more and more attracted to writing long C++ algorithmic functions using successive scoped blocks, as follows: void my_algorithm(const MyStruct1 &iparam1, MyStruct2 &oparam2) { // First block MyStruct3 intermediate_var3; { double temporary_var; //
