I need to check the checked property of a checkbox and perform an action based on the checked property using jQuery.

For example, if the age checkbox is checked, then I need to show a textbox to enter age, else hide the textbox.

But the following code returns false by default:

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

[removed][removed] <input type="checkbox" id="isAgeSelected"/>
