parameter-passing

问题 I require to pass some parameters with AXIOS in react-native but don't know how should I pass parameters with AXIOS. I found this post useful but its not fully satisfy my issue. I need to pass below parameters to fetch all items from API: Working example in PHP: $url = 'https://APISITE.net/api/Stock/GetStockItems?keyWord=6666777788889&locationId=""&entriesPerPage=10000&pageNumber=1&excludeComposites=true'; Its working well in PHP TEST file and i only need to pass keyword value ie

问题 Thank you so much for reading and responding if you can. In one function I test a condition and make a string 'true' or 'false', which then I make a global variable. Then I call another function with that string as the parameter Within that function's if statement, I want to test based off the strings boolean value of 'true' or 'false' $email_form_comments = $_POST['comments']; // pull post data from form if ($email_form_comments) $comments_status = true; // test if $email_form_comments is

问题 How could it be any useful to pass a reference object by reference. The regular usage is as the following: public static void main() { Student st = new Student(); st.FirstName = "Marc"; PutLastName(st); Console.WriteLLine(st.FirstName + " " + st.LastName); } public static PutLastName(Student student) { student.LastName = "Anthony"; } Why would anybody write the following, which does the same thing and does print: "Marc Anthony": public static void main() { Student st = new Student(); st

问题 Consider this simple enum: enum myEnum: String { case abc = "ABC" case xyz = "XYZ" } I want to write a function that can print all cases in an enum. Like.. printEnumCases(myEnum) Expected result: ABC XYZ Note: I can able to iterate an enum like this. But I don't know how to pass the enum. 回答1: You can define a generic function which takes a type as argument which is CaseIterable and RawRepresentable : func printEnumCases<T>(_: T.Type) where T: CaseIterable & RawRepresentable { for c in T

问题 I have problem passing hidden field value in actionlink parameter: productView: @Html.ActionLink("ProductCompare", "ProductCompare", new { ProductIds= **hdnSelectedProductId**) @Html.Hidden("hdnSelectedProductId") Controller Action: public ActionResult ProductCompare(string ProductIds) { return View(); } When user select any product i keep putting product ids in hdnSelectedProductId using javascript.

问题 I have an abstract class Creature that takes a generic type argument, extended by two other classes Human and Spider. Each subclass defines the generic type of its parent. I am stuck with how to pass a subclass as a reference of parent class to a method. public interface IDamagable { void OnSimpleHit(); } public interface IStabAble : IDamagable { void OnKnifeStab(); } public interface ISlapAble : IDamagable { void OnSlap(); } public abstract class Creature<T> where T : IDamagable { public

问题 I am trying to minimize a function that outputs chi-square via scipy and find the mu,sigma,normc that provide the best fit for a Gaussian overlay. from math import exp from math import pi from scipy.integrate import quad from scipy.optimize import minimize from scipy.stats import chisquare import numpy as np # guess intitial values for minimized chi-square mu, sigma = np.mean(mydata), np.std(mydata) # mydata is my data points normc = 1/(sigma * (2*pi)**(1/2)) gauss = lambda x: normc * exp( (

问题 I am writing my fist MyBatis application and I stuck around @Select. I do not know what is the problem with my @Select definition, everything seems fine but I got a Parameter not found exception. I have followed the same pattern when I pass parameters to my my @Insert statement and it works without problem. I use MyBatis 3.4.2. This is my @Select: @Select("SELECT * " + "FROM configuration " + "WHERE key_name = #{key} AND " + "(#{userId} IS NULL AND user_id IS NULL) OR user_id = #{userId} AND

问题 For the record I am completely green in C++ and any other programming language for that matter, so if it's possible I'd be happy if you can answer in a way that I can understand :) I have been working on a simple rock, paper, scissors game recently where I have 3 basic functions, one for the user, one for the bot, and one that choose which one wins the game. I know using system("cls") isn't the best way to go, but I'm not planning on using this outside Windows. The final function results()
