attr(name), property of an object with dash/hyphen in name returns undefined

Description

When using attr(name) to get value of parameter for given object, if the name contains any dash/hyphen followed by letter [a-z] it fails on the conversion to upper case by removing the dash/hyphen.

The code that does that is in the attr function:

name = name.replace(/-([a-z])/ig, function(all, letter){
	return letter.toUpperCase();
});

Can you provide an example?

Changed October 22, 2009 01:11PM UTC by kivanov comment:2

var _object = new Object();
var _property = "my-property";

_object[_property] = "test";

console.log(_object[_property]);
console.log($(_object).attr(_property));
console.log(_object[_property] == $(_object).attr(_property));

Both ways should return the same results, but they are not.

If the property name does not contain "-" followed by [a-z] it works fine.

Any progress on this bug?

The fix seams easy, just remove the regular expression replacement within the attr function, shown above. Unless that is necessary for some internal use.

This is still an issue in v1.4.2
