How Can I Efficiently Check the Status of Checkbox Array Elements Using jQuery?

Finding the Check Status of a Checkbox Array Element Using jQuery

In instances where you need to verify the checked status of specific checkbox element within an array of checkboxes, leveraging jQuery's versatile capabilities can greatly simplify the process.

However, while using code like this often isn't reliable:

function isCheckedById(id) {
    // ...
}

A refined approach involves utilizing jQuery's direct selectors:

$('#' + id).is(":checked")

This expression effectively checks if the checkbox with the specified ID is currently in a checked state.

For situations where you're dealing with an array of checkboxes sharing the same name, obtaining a list of checked elements is achievable with:

var $boxes = $('input[name=thename]:checked');

Subsequently, iterating through each checked checkbox becomes straightforward using:

$boxes.each(function(){
    // ...
});

And determining the number of checked checkboxes is equally convenient:

$boxes.length;
