parameter-passing

问题 So I found an awesome solution to get around needing to use Global variables in jQuery here. Everywhere I say namespace, originally I was going to use a Global var. However I'm not able to send my namespace variable through a param on a simple click function. I want to do this because I have these variables that need to be saved and used to create modal windows as well as to let the app know what dynamically created buttons control what modal. So below is an example of my namespace object

问题 I am trying to pass the "filename" from the function on_file_open_clicked defined as: import gi gi.require_version("Gtk", "3.0") from gi.repository import Gtk, Gdk, Pango UI_INFO = """ <ui> <menubar name='MenuBar'> <menu action='FileMenu'> <menuitem action='FileOpen' /> <menuitem action='FileQuit' /> </menu> </menubar> </ui> """ class MenuManager(Gtk.UIManager): def __init__(self): super().__init__() action_group = Gtk.ActionGroup("my_actions") self.add_file_menu_actions(action_group) self

问题 This is probably very basic, but I have tried so many things and the always give errors. Basically what I'm trying to do is run a procedure every time a cell gets changed in Excel. So I'm using Sub Worksheet_Change(ByVal Target As Range). All works well, but in this procedure, I'm calling another sub procedure several times. I want to reuse the 'Target' value in this procedure, but for some reason, I can't find how to do it. I tried placing 'Public rTarget As Range' and do a 'rTarget = Target

问题 I'm trying to load some names from a firebase to my list view and then when I click on any of the items it shows the name on the next view using the autogenerated id inside firebase for the respective name. Here's my code: controllers.js: angular.module('starter.controllers', []) .controller('ListCtrl', function($scope, UserService) { var listAllUsers=function(){ UserService.listAll().then(function(users){ $scope.list=users; }); } listAllUsers(); }) .controller('DetailCtrl', function($scope,

问题 I'm using the .NET Core 2 "Razor Pages" format for a web app. It allows you to define how to map the URL to variable names with a simple directive at the top: @page "{personId:int?}" The above, for example, would map the URL /Person/Index/123 to the IndexModel.OnGetAsync(int personId) function so that personId would have a value of 123. However, I've noticed that these values seem to be automatically added to any URL they could be, if a link exists on the page. If I add the following to the

问题 This is part of a bigger selection, but I have stripped it down to the essential question : Compare this two SQL queries - the first works with a constant, the second with a variable, both have the same value (lets say 180). The one with the constant displays result immediately (e.g. within milliseconds), the one with the variable takes a few seconds to yield the same result. Where is the catch ? Query 1: SELECT * FROM table WHERE field > 180 Query 2: DECLARE @V INT SET @v = 180 SELECT * FROM

问题 I am trying to just get the sum of row 2. My code compiles but doesn't print anything. Some guidance? Also, building off of the first question, how would I access the largest element in column 3? import java.util.*; public class TestCode { public static void main(String[] args) { int array[][] = {{1,2,3}, {4,5,6}, {7,8,9}, {10,11,12}}; int sum = 0; //print(array); } public static void print(int list[][]) { for(int row = 0; row < list.length;row++) { int[] sum = new int [3]; for(int column = 0

问题 i have searched for this answer and i got 2 sort of replies,which i found i could implement it. they are.. window.location.href=href='2ndpage.html?var id=results.rows.item(1).id'; *results.rows.item(1).id- this the value i am getting it from the database---it would be the value of the id of the element in the DB. to get the value,i implemented this code.. function onDeviceReady() {var db = window.sqlitePlugin.openDatabase("Database", "1.0", "Database",1000000); console.log("processing

问题 I am having trouble in implementing an approach to call Newton's method in a Fortran program. So I want to use Newton's method to solve an equation following the link However, my program is slightly different with the example above. In my case, the equation requires some additional information which are produced during runtime. subroutine solve(f, fp, x0, x, iters, debug) which means the f is calculated not only based on x, but also a few other variables (but x is the unknown). I have a
