attr(BooleanAttribute) and could be released as early as Tuesday, May 10, 2011. This version will return either the name of the attribute (if true) or undefined (if false) for.

This appears to be a backwards compatibility fix for reading properties, but not setting them. attr() will bring back the property boolean value as the attribute in the next release (probably 1.6.1). Okay, ready for this, one more item to throw at you… if I’m reading the bug ticket right, if an attribute does not exist but the property does, the. This all makes sense, though a bit confusing since the attribute is basically converted into a property at DOM load making upgrading to version 1.6 much more difficult than most recent version upgrades, so be sure to do some extra testing.

Try this case on for size… If I don’t set the checked attribute or property isCheckedAttr will always return “undefined” (not an empty string) and isCheckedProp will return false (until I click the checkbox which will make it true). The isCheckedProp will still return “true”. This example in jQuery 1.6 will return “checked” for isCheckedAttr (remember 1.5.2 returned “true”). In HTML and XHTML you can set the checked property as an attribute. Var isCheckedProp = $('input').prop('checked') Notice 1.5.2 returned “true” instead of “” for isCheckedAttr.

The following example will return isCheckedAttr as “” and isCheckedProp as “true”. attr() method will return when referencing DOM properties. Var isCheckedAttr = $('input').attr('checked') Take for example in version 1.5.2, the following code would return isCheckedAttr as “true”. JQuery 1.6 released a significant change to the way it handles DOM attributes and properties.
