jQuery: Check if all checkboxes selected - Code snippet

When working with checkboxes in jQuery, it is often necessary to check if all checkboxes have been selected. This can be achieved with a simple code snippet.

First, we need to select all the checkboxes using the jQuery selector. We can do this by using the $('input[type="checkbox"]') selector.

Next, we need to check if all the checkboxes are checked. We can do this by using the is(':checked') method. This method returns true if the checkbox is checked and false if it is unchecked.

Finally, we need to check if all the checkboxes are checked. We can do this by comparing the number of checked checkboxes to the total number of checkboxes. If they are the same, then all checkboxes are checked.

Here is the code snippet:


if ($('input[type="checkbox"]').length == $('input[type="checkbox"]:checked').length) {
  // All checkboxes are checked
} else {
  // Not all checkboxes are checked
}

By using this code snippet, we can easily check if all checkboxes are selected and perform further actions accordingly.
