Как прокручивать элементы в галерее изображений в django с помощью javascript

Я пытаюсь сделать галерею изображений на вкладке в django, используя javascript для динамической активации. Как передать переменную в onclick="currentSlide()", чтобы она работала инкрементально .

#template -property_info.html

        
<div class="container">

<!-- Full-width images with number text -->
{% for p in images %}
<div class="mySlides">
    <div class="numbertext">1 / 6</div>
    <img src="{{p.images_of_property.url}}" style="width:100%">
    <h1>{{p.id}}</h1>
</div>
{% endfor %}



<!-- Next and previous buttons -->
<a class="prev" onclick="plusSlides(-1)">&#10094;</a>
<a class="next" onclick="plusSlides(1)">&#10095;</a>

<!-- Image text -->
<div class="caption-container">
    <p id="caption"></p>
</div>

<!-- Thumbnail images -->
this is where i have issues . i dont know how to pass the value so it can increment dynamically.
{% for p in images %}
<div class="row">
    <div class="column">
    <img class="demo cursor" src="{{p.images_of_property.url}}" style="width:100%" onclick="currentSlide('{{p.id}}')" alt="property img">
    </div>
    {% endfor %}
    
</div>
</div>
