Question

I know that in WordPress we can do the following:

preg_match("/\p{Arabic}/u",
get_the_title())

How can we do this in JavaScript? Thanks in advance.

Answer 1

Since you know how to detect your language in php then its just a simple matter of passing a value from your php code to your javascript code.

eg.

<?php $language = get_language_on_whatever_way_you_want(); ?>
<script type="text/javascript">
function alertMeTheLanguage() {
    var language = '<?php echo $language; ?>';
   alert('Your language is  <?php     echo $language; ?> ' );
}
</script>
