This SharePoint tutorial, we will discuss how to change the language using JavaScript in SharePoint or in Asp.Net applications.
As we know most of the time we are face challenges to configure the multi-language settings in our application. So here I am going to briefly explain about changing the language using JavaScript Code which you can use in SharePoint as well as in asp.net applications.
You can also download the complete Visual studio code solution.
Change language using javascript in sharepoint
Step 1: Before going to start, we have to add the below JavaScript references in our application.
You can also use the entire code inside a script editor or content editor web part in SharePoint Online or SharePoint On-premises versions also.
<script src="JavaScript/jquery.min.js"></script>
<script type="text/javascript" src="JavaScript/language.js"></script>
<script type="text/javascript" src="JavaScript/js.cookie.min.js"></script>Language.JS: This file I have mainly used to keep both language text. And I have used keys instead of text on the page. Below is the Example of a small page that I have created.
And below is the structure of my application, here I have used visual studio code.
Step 2: At the top of the page, I have added a button where you can switch the language in a button click.
Step 3: I have used CSS to change the position of text from left to right and right to left based on the language which you have selected. Add the below CSS in your application.
<link href="css/bootstrap.min.css" rel="stylesheet" />
<link href="css/all.css" rel="stylesheet"crossorigin="anonymous" />
<link href="css/all.css" rel="stylesheet" />
<link title="english" rel="stylesheet" href="css/theme.css"/> Step 4: In this step, I have applied the CSS using JavaScript based on the language selected.
<script type="text/javascript">
function ChangeLanguage(language) {
Cookies.set('att-lng', language);
SetContentLanguage(language);
if (language == "en") {
$('#ln-seletor').text("عربى");
$("body").attr('dir', 'ltr');
$("body").attr('lang', 'en');
$("head link[title='english']").each(function (index, item) {
if ($(item).attr("href").indexOf('theme-ar.css') > 0) {
$(item).attr("href", "css/theme.css");
}
});
}
else {
$('#ln-seletor').text("English");
$("body").attr('dir', 'rtl');
$("body").attr('lang', 'ar');
$("head link[title='english']").each(function (index, item) {
if ($(item).attr("href").indexOf('theme.css') > 0) {
$(item).attr("href", "css/theme-ar.css");
}
});
}
}
function SetContentLanguage(language) {
$('.language').each(function (index, element) {
if ($(this).attr('key') == 'requested-justification') {
$(this).text((arrLang[language][$(this).attr('key')]).replace("()","("+ $(this).attr('data-attr')+")"))
}
else {
$(this).text(arrLang[language][$(this).attr('key')])
}
});
}
$(function () {
var lang = "en";
var language = Cookies.get('att-lng');
if (language != undefined && language != null && language != '')
lang = language;
ChangeLanguage(lang);
//onclick
$('#ln-seletor').on("click", function () {
if ($(this).text() == "English")
ChangeLanguage("en");
else
ChangeLanguage("ar");
});
});
</script>step 5: Below is the full source code where you can debug this application very easily.
