How to get User email Address ?

Answer 1

Liferay JS utility's Liferay.ThemeDisplay or just themeDisplay does not implicitly contain user's email address. It just exposes userId and userName while it doesn't have any getUser or User object in it.

However, you can achieve that by overridding \\html\\common\\themes\\top_js.jspf using JSP hook. All you need to do is to add following lines below getUserName: function() { :

getUserEmailAddress: function() {
    <c:choose>
        <c:when test="<%= themeDisplay.isSignedIn() %>">
            return "<%= UnicodeFormatter.toString(user.getEmailAddress()) %>";
        </c:when>
        <c:otherwise>
            return "";
        </c:otherwise>
    </c:choose>
},

Then you will be able to get user's email address by either Liferay.ThemeDisplay.getUserEmailAddress(); or themeDisplay.getUserEmailAddress(); .
