Answer 1

Both of these should work:

$("#captureImage").prop('checked', false);

AND/OR

$("#captureImage").removeAttr('checked');

... you can try both together.

Answer 2

using .removeAttr() on a boolean attribute such as checked, selected, or readonly would also set the corresponding named property to false.

Hence removed this checked attribute

$("#IdName option:checked").removeAttr("checked");

Answer 3

try something like this FIDDLE

    try
      {
        navigator.device.capture.captureImage(function(mediaFiles) {
        console.log("works");
         });
      }

    catch(err)
      {
        alert('hi');
        $("#captureImage").prop('checked', false);

      }

You could try $(this):

$("#captureAudio").live("change", function() {
    if($(this).val() !== undefined) { /* IF THIS VALUE IS NOT UNDEFINED */
            navigator.device.capture.captureAudio(function(mediaFiles) {
            console.log("audio");
        }, function() {
            $(this).removeAttr('checked'); /* REMOVE checked ATTRIBUTE; */
            /* YOU CAN USE `$(this).prop("checked", false);` ALSO */
            _callback.error;
        }, {limit: 1});
    }
});

Sorry, I solved my problem with the code above:

$("#captureImage").live("change", function() {
    if($("#captureImage:checked").val() !== undefined) {
        navigator.device.capture.captureImage(function(mediaFiles) {
            console.log("works");
        }, function(exception) {
            $("#captureImage").removeAttr('checked').checkboxradio('refresh');
            _callback.error(exception);
        }, {});
    }
});

Try this to check

$('#captureImage').attr("checked",true).checkboxradio("refresh");

and uncheck

$('#captureImage').attr("checked",false).checkboxradio("refresh");
