问题 I'm trying to filter an object using the filter() function in javascript . I want to filter againts an array like this: [1615, 1616]. It's referenced in the code as value.verdier. Dataset is a large array holding objects that have several properties, parsed from a JSON string. Each object in the array has a property named kat_id. The goal is to reduce the array so that it only holds objects where kat_id=1615 or kat_id=1616. Or any other value that I have in value.verdier. My code is like this

问题 Im trying to figure out how to include a .pyc file in a python script. For example my script is called: myscript.py and the script I would like to include is called: included_script.pyc So, do I just use: import included_script And will that automatically execute the included_script.pyc ? Or is there something further I need to do, to get my included_script.pyc to run inside the myscript.py ? Do I need to pass the variables used in included_script.pyc also? If so, how might this be achieved?

问题 I have set up my web.xml file which loads footer and header but I want to separate my login page to load it without header footer. Does any know how can I achieve this. Here is my Web.xml file configuration. I am using Netbeans <jsp-config> <jsp-property-group> <description>JSP configuration for the store front</description> <url-pattern>/index.jsp</url-pattern> <url-pattern>/WEB-INF/view/*</url-pattern> <url-pattern>/WEB-INF/jspf/error/*</url-pattern> <include-prelude>/WEB-INF/jspf/header

问题 Is there any expression possible for the syntax to include multiple headers at once, with no need to write the "#include"-expression for each file new? Like, for example: #include <stdio.h>, <stdlib.h>, <curses.h>, <string.h> /* Dummy-Expression 1. */ OR #include <stdio.h> <stdlib.h> <curses.h> <string.h> /* Dummy-Expression 2. */ Question is for C AND C++. 回答1: No, there is no way to do this. You have to type out (or copy) each #include to its own line, like this: #include <stdio.h> #include

问题 I believe this is a simple question but I am having a hard time figuring out why this is not working. I have a django project and I've added a second app (sales). Prior to the second app, my urls.py simply routed everything to the first app (chart) with the following: urlpatterns = [ path('admin/', admin.site.urls), path('', include('chart.urls')), ] and it worked fine. I have read the docs over and over a looked at many tutorials, so my impression is that I can simply amend the urls.py to

问题 I'm using Rails 5. I want to know if a varaible (which you can assume is a String) contains at least one letter (upper case or lower case). However, I don't want to use regular expressions (I've noticed if the encoding is not UTF-8, regular expressiosn tend to crash). So I'm wondering how I can check if a string hast at least one letter. THis doesn't work input.downcase.include?("abcdefghijklmnopqrstuvwxyz") 回答1: Try this str.count("a-zA-Z") > 0 The count function accepts character sets as

问题 I am trying to learn how to deal with a lot of includes, and still keep my code tidy. I am programming a Qt application and I have put files commonly used (and that doesn't change) in a file called "Util.h". Util.h #pragma once #include <Core/IObserver.h> #include <Core/Math.h> #include <QAction> #include <QDockWidget.h> #include <QFileDialog> #include <QGraphicsBlurEffect> #include <QLabel.h> #include <QMainWindow.h> #include <QMenu.h> #include <QMessageBox.h> #include <QShortcut.h> #include

问题 Some header files are present in /src/dir1/ (eg: a.h , b.h , c.h etc). My source file is present in /src/dir2/file.cpp . I used some header files that are present in /src/dir1/ but during compilation I got errors like header file not found . Then I changed the include path like #include "../src/dir1/a.h" , then error is gone in file.cpp but I get not found error in the headers files that are present in /src/dir1 . Because I included the header file say a.h , that a.h included some other

问题 When I work on my personal C and C++ projects I usually put file.h and file.cpp in the same directory and then file.cpp can reference file.h with a #include "file.h" directive. However, it is common to find out libraries and other kinds of projects (like the linux kernel and freeRTOS) where all .h files are placed inside an include/ directory, while .cpp files remain in another directory. In those projects, .h files are also included with #include "file.h" instead of #include "include/file.h"
