Use .prop method.

$('#isWorking').prop('checked', true);  // check it
$('#isWorking').prop('checked', false); // uncheck it

why use prop method instead of attr? – Dec 25 '13 at 08:35

@lttyhead Because it is a property over attribute. – xdazz Dec 25 '13 at 08:41
The OP is targeting to id thus attr would be better way. – Bhojendra Rauniyar Dec 25 '13 at 08:47

@C-link What do you mean by `targeting to id`? – xdazz Dec 25 '13 at 08:50

For set Checkbox value you need to use .prop

$('#isWorking').prop('checked', true);
$('#isWorking').prop('checked', false);

Setting "checked" for a checkbox with jQuery?

you can simply do this,

$("#isWorking").attr('checked', true);

to see if a checkbox is checked or not:

$('#isWorking').is(':checked');

Use .prop()

 $('#isWorking').prop('checked', true/false);

A good read .prop() vs .attr()

Use this:

$("#isWorking").prop("checked",true); //check
$("#isWorking").prop("checked",false); //uncheck

Hope it helps.

`.prop()` is recommended now. – jfriend00 Dec 25 '13 at 08:35
