How to change the language of freshchat dynamically (on the fly)?

hi ​@evgen12 

To change the locale and reinitiate the widget with the selected locale, please try this shared script. I have added list of languages to a dropdown and on selection will destroy any widget instance previous initialized and will reinitialize the widget with the selected language.

<b> Choose language </b>
<select id = "myLang" onchange = "myLang()">
<option> ---Languages-- </option>
<option> en </option> 
<option> de </option>
<option> es </option>

</select>
<script>

let lang_selected;

function initWidget(lang_selected = 'en'){
    window.fcWidgetMessengerConfig = {	
        locale: lang_selected,
    }

    var freshchatScript = document.createElement('script');
    freshchatScript.src = '//fw-cdn.com/*******.js'; // add the unified js here
    freshchatScript.setAttribute('chat', 'true');
    //freshchatScript.setAttribute('widgetId', 'widgetUUId from the settings');
    freshchatScript.id = 'freshchatScript'; // Assign an id to the script
    // Append the script to the head of the document
    var head = document.head || document.getElementsByTagName('head')[0];
    head.insertBefore(freshchatScript, head.firstChild);
}
function myLang() {
    lang_selected = document.getElementById("myLang").value;

    console.log(" the lang selected is ==> "+lang_selected);
    if (window.fcWidget?.isInitialized() == true) {
  		console.log('Widget already initialised');
        window.fcWidget.user.isExists().then(function(data) {
            console.log('User data', data);
             if(data.data && data.success){
                window.fcWidget.user.clear();
                console.log('cleared');
            } else {
            console.log('user doesnt exist');
			window.fcWidget.destroy();
   		  }
            }, function() {
            console.log("Error fetching user");
        });
         window.fcWidget.on("user:cleared", function() {
      // do some cleanup after user cleared
         window.fcWidget.destroy();
        });
   		 window.fcWidget.on("widget:destroyed", function() {
     	 console.log('After widget destroyed');
     	 initWidget(lang_selected);
  });

	}
	else {
  		console.log('Widget Not Initialised');
        initWidget(lang_selected);
 		 //Do Something Else
		}
    }
    initWidget(lang_selected);
</script>

Let me know if works for u.

Thanks!
