Thymeleaf to check null and display value accordingly

How to display user_name and user_id inside th:title.

HTML

<div class="ui-widget tooltip-wrapper" data-toggle="tooltip" data-placement="right" th:title="*{user_id} + ${'-' + creator.user_name}" > </div>

I need to check whether user_id is not null and also user_name is not null and display both in tool tip.

Sample : 101 - Janet

I tried with th:title="*{user_id!=null} + ${'-' + creator.user_name}". But it is displaying as true instead of the actual value.

Currently if the value is null, it is displaying as null in tooltip. But I don't want to display if the value is null or empty.

Can anyone help on this. Thanks.

Solution

  • Try this

    th:title="*{user_id?:''} + '-' +${creator.user_name?: ''}"
