const checkbox = $("#myCheckbox"); if (checkbox.is(":checked")) { console.log("Checkbox is checked"); } else { console.log("Checkbox is not checked"); }
- First, we retrieve the checkbox element using the jQuery selector '$("#myCheckbox")' and assign it to the variable **"checkbox".
- Using the 'is(":checked")' method of the checkbox element, we then determine whether the checkbox is selected.
