How to Check Checkbox Status Using jQuery

In jQuery, the attr('checked') function is not used to check the checked property of a checkbox. Instead, you can use the following methods:

1. Using DOM Element's checked Property

The checked property of the checkbox DOM element provides the checked state of the checkbox:

if (document.getElementById('isAgeSelected').checked) {
  $("#txtAge").show();
} else {
  $("#txtAge").hide();
}

2. Using jQuery's change() Event

When the checkbox is clicked, the change() event is triggered. You can use it to toggle the visibility of the text box:

$('#isAgeSelected').click(function () {
    $("#txtAge").toggle(this.checked);
});
