$(document).ready(function(){ is used to load .js file or loading js functions but those functions won’t be execute.

create set_user_status.js file, it looks similar to this:

function setUserStatus(v1,v2,v3){
    alert(v1+ v2+ v3);
    //or
    console.log(v1+ v2+ v3);
}

<script type="text/javascript" src="js/set_user_status.js"></script>
