Hello Dev,
Here's a simplified clarification on a way to get the values of decided on checkboxes the usage of jQuery:
If you have a set of checkboxes and also you want to retrieve the values of those which can be checked whilst a button is clicked, jQuery makes this truthful. You can iterate over the checkboxes, locate those which can be checked (enter[type=checkbox]:checked), after which accumulate their values into an array.

In this Example:
We have a collection of checkboxes labeled "Checkbox 1" through "Checkbox four".
When the "Get Selected Checkbox Values" button is clicked (#btnGetSelected), jQuery listens for the press event.
Inside the press handler feature, we initialize an empty array selectedValues to save the values of selected checkboxes.
Using $('input[type=checkbox]:checked').Every(...), jQuery selects all checked checkboxes and iterates over them.
For each checked checkbox, $(this).Val() retrieves its value, that's then driven into the selectedValues array.
Finally, we display an alert with the selected checkbox values joined by using a comma, or a message indicating that no checkboxes are checked if selectedValues is empty.
This method lets in you to dynamically retrieve and manage the values of decided on checkboxes the usage of jQuery.
