Issue with jQuery 1.6: Can't uncheck checkboxes

Reported by: Bertrand Marron <me@…> Owned by: Timmy Willison
Priority: high Milestone: 1.6.1
Component: attributes Version: 1.6
Keywords: Cc:

Removing the checked attribute, or setting it to false, used to uncheck checkboxes in previous versions of jQuery.

jQuery 1.6 doesn't let you.

jQuery 1.6 removes the ambiguity between attributes and properties. The checked attribute (by spec) only sets the default value. There is no checked attribute on that checkbox to remove. You need to set the checked property to false: .prop('checked', false) or .checked = false. We understand this will break some people's code so this will be changed to how it worked previously for 1.6.1.

Set corresponding property to false when removing boolean attributes. Fixes #9094

Although this bug report only addresses boolean false, it should be noted that .attr('foo', true) is also broken. See http://jsfiddle.net/YsvyP/

Reported the boolean true case as a separate bug: #9103

1.6 version seems to have bug on uncheck checkboxes. The following code works in 1.4.3, but not 1.6. Any idea? $('input:checkbox').attr('checked', false);

comment:8 Changed 12 years ago by Timmy Willison

@mc: You can use prop to set the property, which is what you are really after. $('input:checkbox').prop('checked',false);

Thanks a lot. Timmywil. "prop" works fine with 1.6 version in IE8.
