05. Resource bundles (i18n)

 1. Introduction

There are several ways to use resource bundles. By now, let's use java instead of xml (<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>)

1. First lay the resource files (main_language.properties) in the folder src/main/resources/i18n


2. Create a jsp file

3. Add a new page directive with the includes (Locale y ResourceBundle)

4. Get the locale from the request and the resource bundle from the relative path "i18n/main"

5. Assign the localized value using <%=bundle.getString("key") %>

The source code is


<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ page import = "java.io.*,java.util.Locale, java.util.ResourceBundle" %>        
<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>JSP-02</title>
  </head>

  <body>
    <% 
      Locale locale = request.getLocale();
      ResourceBundle bundle = ResourceBundle.getBundle("i18n/main", locale);
    %>
    <p id="pInstruct"><%=bundle.getString("instruccions") %></p>
  </body>
</html>

10. Some Javascript & JQuery concepts

1. Serializing  const myObj = { fld01 : 1 , fld02 : 2 , fld03 : "\"hello\"" } ; //1. Serialize to json // returns { "fld01" : 1 , "fld02" : 2 , "fld03" : "\"hello\"" } var myJsonSerialize = JSON. stringify (myObj); //2. Serialize to URL ->equivalent to $("form").serialize) // returns fld01=1&fld02=2&fld03=%22hello%22 var myURLSerialize = $. param ( myObj ); //3. Serializing a form to pass ass a URL // returs something like FirstName=Mickey&LastName=Mouse $( "form" ). serialize (); //4. Get the form as an object var formData = new FormData ($( 'form' )[ 0 ]); //5. Convert the formdata to json var data = JSON. stringify ( Object . fromEntries (formData)); 2. JQuery click events conflict It is recommended not to use click and dbclick at the same time with jquery (and jsgrid ). If you use alert or console.log  in "click" event th...

14 Typescript (2) with jquery, bootstrap and other module stuff

Imagen
1. Introduction Modules are rather tedious and difficult to be understood. There are many module types (Commonjs, AMD, UMD, System) as Jurgen Van Moere explains.  Node, however, works well with Commonjs modules but cannot integrate well with other modules (AMD, System..) Webpack comes to the rescue, but it is a bit difficult to use. With the help of some sites like Neoguias  and  Swashbuckling  this task is much more easier. Our schedule is: Create the basics Create a simple web page with html and javascript Creating a simple module Importing and using a simple node module (is-what) and @types Importing and using jquery 1. The basics. Installation Open VS Code and execute these commands in the terminal window # create the project folder mkdir webpack-jq cd webpack-jq # create the package.json and ask for project basic info npm init -y # install webpack and cli (opt -D is equivalent to --save-dev ) npm i -D webpack webpack-cli # create the folder src (source...
