Why jQuery throwing undefined for checkbox checked property ?

Following code works inside the onchange property of checkbox:

 onchange="if(this.checked)$('#row_date').show();else $('#row_date').hide();"

but jquery 

alert($('#apply_range').checked) // throw undefined, either checked or unchecked

not working.

You have to either use $('#apply_range').is(":checked") or directly access DOM element: $('#apply_range')[0].checked.

checked is a property of the DOMElement, not a jQuery object. To get that property from the jQuery object, use prop():

console.log($('#apply_range').prop('checked'));

Or you can access the DOMElement in the jQuery object directly like this:

console.log($('#apply_range')[0].checked);

// or

console.log($('#apply_range').get(0).checked);
