Detecting the language preference of users can be very important for Websites or Web Apps to increase user interaction. By using JavaScript, this task can be easily done by using:
Languages property is available for the navigator interface, which returns the most preferred / user-preferred language set in the web browser. This property is read-only.
Syntax:
navigator.languages // Or navigator.language
Return Value:Â
- The navigator.languages property will return an array that stores the languages in an order in which the language most preferred by the user will be the first element.
- The navigator.language property will return the first element of the array which is returned by the navigator.languages property i.e. the most preferred user language.
Note: Language property is a read-only property, thus it is only possible for us to get the value, we cannot make changes to the user preferred language.
Example 1: Getting the most preferred language.
Javascript
<script>     var usrlang = navigator.language             || navigator.userLanguage;     console.log(         "User's preferred language is: "        + usrlang); </script> |
Output:
User's preferred language is: en-US
Example 2: Getting the preferred language array.
Javascript
<script> Â Â Â Â var usrlang = navigator.languages; Â Â Â Â console.log(usrlang); </script> |
Output:
['en-US', 'en'] 0:"en-US" 1:"en" length :2
