for loop in thymeleaf

Question

How can I do the following (java):

for(int i = 0; i < 81 ; i+=20){    //Should loop through 5 times! } 

in Thymeleaf?

I've tried this:

<option th:each="i : ${#numbers.sequence( 1, 81/20)}">    <p th:text="${ i }"></p> <!-- THIS loops 4 times, instead of 5 --> </option> 

The problem is that it is not as accurate as the java piece of code. How to do this?

Answer 1

Add step to your code is quite easy.

#{numbers.sequence(0, 81, 20)} 

Answer 2

use iterStat key word to iterate. Example If you have an Array of String and you are iterating the same using thymeleaf.

<div th:each="str,iterStat : strings">    <span th:text="${str}"/><!--This will print the index value-->    <span th:text="${iterStat.index}"/><!--This will print the Index--> </div>
