Multi language page with Javascript or jquery

Question

Currently I am working on web app that will support several languages. Therefore I prepared table in my database with translations. However, I am not sure how to populate we

Answer 1

Use on every piece of text you want to change according to the language a span HTML tag because you can embed inline on every piece of HTML (contrary to div or p which have a display:block by default). Then for each span use a class with a name starting with a certain pattern, for example:

Then using jQuery's function .each change every span tag that matches the pattern lang in its class name, according to the selected language.

I put also here a simple example for you to check.

var LanguageList = {
  "EN" : "English",
  "ES" : "Español",
  "PT" : "Português"
};

//languages Objects
var WORDS_EN = {
  "text1" : "text One",
  "text2" : "text Two"
};

var WORDS_ES = {
  "text1" : "texto Un",
  "text2" : "texto Dos"
};

var WORDS_PT = {
  "text1" : "texto Um",
  "text2" : "texto Dois"
};


window.onload = initialize;

function initialize() {
  var $dropdown = $("#country_select");    
  $.each(LanguageList, function(key, value) {
    $dropdown.
      append($("").
      val(key).
      text(value));
    });
    
  loadsLanguage("EN");
}

function loadsLanguage(lang){
  /*fills all the span tags with class=lang pattern*/ 
  $('span[class^="lang"]').each(function(){
    var LangVar = (this.className).replace('lang-','');
    var Text = window["WORDS_"+lang][LangVar];
    $(this).text(Text);        
  });
}

div{
  margin: 15px;
}
