What is the best way to choose the unique identifier of an HTML element inside a for loop in a Django template?

I need help selecting an HTML button that is generated within a for loop in a Django template using JavaScript. How can I assign a unique ID to each button and select it correctly in JavaScript? Currently, all buttons have the same ID within the loop, resulting in no action when clicked.

html

% for post in page_obj.object_list %}
            <div class = "individual_posts">
                <a href="{% url 'username' post.user %}"><h5 class = "post_user">{{ post.user }}</h5></a>
                <h6 id = "post_itself">{{ post.post }}</h6>
                {% if post.user == request.user %}
                    <button id="editButton" class="edit_button">Edit</button>
                {% endif %}
            </div>
        {% endfor %}

JavaScript

document.addEventListener('DOMContentLoaded', function(){
    document.querySelector('#uniqueIdHere').onclick = edit_email();
})

Answer №1

To distinguish your buttons, consider adding the forloop counter to their HTML id:

id="editButton{{ forloop.counter0 }}"

This way, you can easily target the specific button in your JavaScript code.

If you want to apply onclick functionality to all buttons, update your selector in the JS from # to ('.edit_button') for it to work universally.
