I have a list of persons that I need to display, and for each person there is an input for age.
I need to sum the ages when im writing; I mean if I have 5 persons when I’m on the 5th record, i need the total of previous 4 ages like this one : Calculate sum from number type input fields by javascript
this is my code :
<tr th:each="person : ${persons}">
<td th:text="${person.first_name}"></td>
<td th:text="${person.last_name}"></td>
<td th:text="${person.phone}"></td>
<td><input id="age" class="form-control"
type="text" name="age" th:field="*{ages}">
</td>
</tr>
Total : <input type="text" name="total" id="total"/>
