If no uploaded document, change the classname in views

Hi, Metabox. I would like to ask for help. How can I achieve/convert this using JQuery in views? So basically I want to create a statement if there is no document uploaded I want to change a axisting class inside existing HTML element (div).

{% if post.upload_documents is empty %}
    (I want to target the specific class from HTML element, add class and remove other class)
{% else %}
    (No action)
{% endif %}

Thanks in advanced
