How should I apply the if-else condition to display a different menu for people with different user roles?

I have two user roles: ie

1: roleId for admin user and 2: roleId for regular user

The logic I tried was written in two javascript files (.js files as follows):

First file: prj.js

var ref = new Firebase("https://prj.firebaseio.com");
var loggedInUser = [];
$(document).ready(function() {
    authData=ref.getAuth();

    if(authData == null){
        //TODO find an elegant way to manage authorization 
    //  window.location = "../index.html";
    }else{
        ref.child("users").child(authData.uid).on("value", function(snapshot){
            $( "span.user-name").html(snapshot.val().displayName);  
            loggedInUser.displayName = snapshot.val().displayName;
            loggedInUser.roleId = snapshot.val().roleId;
        });         
    }
});

Second file: navigation.js

appraisalMenuHTML = '       <li class="{{appraisal}}" class="dropdown"><a class="dropdown-toggle appraisal"'
    +'          data-toggle="dropdown"  href="/prj/pages/appraisal/appraisalDashboard.html"><span id="appraisal"> Appraisal</span></a>'
    +'          <ul class="dropdown-menu">'
    +'              <li><a href="/prj/pages/appraisal/appraisalDashboard.html">Submit review </a></li>'
    +       ' </ul></li>';

userOptionsHTML = ' <ul class="nav navbar-nav navbar-right">'
    +'      <li class="dropdown"><a class="dropdown-toggle"'
    +'          data-toggle="dropdown" href="#"><img src="/prj/images/settings.png"/></a>'
    +'          <ul class="dropdown-menu">'
    +'              <li><a href="/prj/pages/appraisal/reports.html"> Appraisal</a></li>'
    +'          </ul>'
    +       '</li>'
    +'      <li class="dropdown"><a class="dropdown-toggle user-name"'
    +'          data-toggle="dropdown" href="#"><span class="user-name"></span><span class="caret"></span></a>'
    +'          <ul class="dropdown-menu">'
    +'              <li><a href="/prj/pages/profile.html"> Profile</a></li>'
    +'              <li><a href="/prj/index.html"> Logout</a></li>'
    +'          </ul>'
    +       '</li>'
    +'  </ul>';



navHTML = 
    '<nav class="navbar navbar-inverse">'
    +'<div class="container-fluid">'
    +'<div class="navbar-header">'
    +'  <button class="navbar-toggle" type="button" data-toggle="collapse"'
    +'      data-target="#securedNavbar">'
    +'      <span class="icon-bar"></span> <span class="icon-bar"></span> <span'
    +'          class="icon-bar"></span>'+' </button>'+'</div>'+'<div class="collapse navbar-collapse" id="securedNavbar">'
    +'  <ul class="nav navbar-nav">'
    +'      <li class="{{feeds}}"><a href="/prj/pages/feeds.html"><img src="/prj/images/darpan-logo.png" height="20px" /> Home</a></li>'
    +'      <li class="{{projects}}" class="dropdown"><a class="dropdown-toggle projects"'
    +'   data-toggle="dropdown" href="#"><span class="projects">Projects</span></a>'
    +'          <ul class="dropdown-menu">'
    +'              <li><a href="/prj/pages/project/projectList.html">List</a></li>'
    +'              <li><a href="/prj/pages/project/createNewProject.html">Add new project</a></li>'
    +'          </ul>'
    +'      </li>'
    +'      <li class="{{training}}"><a href="#">Training</a></li>'

    + appraisalMenuHTML

    +'      <li class="{{recruitment}}"><a href="#">Recruitment</a></li>'
    +'      <li class="{{users}}" class="dropdown"><a class="dropdown-toggle users"'
    +'      data-toggle="dropdown" href="/prj/pages/user/userList.html"><span class="users">Users</span></a>'
    +'          <ul class="dropdown-menu">'
    +'              <li><a href="/prj/pages/user/userList.html">List</a></li>'
    +'              <li><a href="/prj/pages/user/createNewUser.html">Add new user</a></li>'
    +'          </ul>'
    +'      </li>'
    +'  </ul>'

    + userOptionsHTML

    +'</div>'
    +'</div>'
    +'</nav>';
    function darpanNav(selectedTab){
    alert('Object is : '+loggedInUser.toString());  
    theCompiledTemplate = navHTML.replace("{{"+selectedTab+"}}", "active")
    newRow = $("#nav-div").html(theCompiledTemplate);
}

HTML file:

<!DOCTYPE html>
<html lang="en">
<head></head>
<body>
.
.
.
.
.
.

<script src="../js/prj.js"></script>

    <script src="/prj/js/navigation.js"></script>

    <script>
    darpanNav("feeds");

    </script>

</body>
</html>

Note. All necessary libraries and files are included. So don’t worry about it.

Now what I want to achieve is to apply the if-else condition to the contents of a variable navHTMLfrom a file navigation.jsbased on user roles. That is, if roleId is 2, then I do not want to display the content appraisalMenuHTML, and if it is 1, display it.

How do I achieve this?
