Thanks for taking the time to contribute to the jQuery project! Please provide a reduced test case on http://jsFiddle.net that reproduces the issue experienced to help us assess your ticket!

Additionally, test against the jQuery (edge) version to ensure the issue still exists.

Why would you pass .attr() a number and not a string?

Agreed with miketaylr, however:

Tested with jQuery (edge) here http://jsfiddle.net/ez57B/3/ across Chrome latest, Firefox 4, Opera, IE6 and IE8. All of these browsers had no problem at all setting the checked value using a number rather than a string with no exception experienced.

Please ideally use the string version instead regardless as we haven't documented a number functioning correctly for 'checked' values.

I don't know what is edge, I'm using 1.6.1 uncompressed and the error is in line 2196 : "value.toLowerCase is not a function". prop() is working fine with this. Also documentation says nothing about expected argument type. Some users are using 1/0 as boolean states, and it works with object properties like checked, so maybe you should handle this properly.

It may work now, but your call does not make sense. You can do .attr("checked", "checked"), .attr("checked", true), .prop("checked", true), or simply elem.checked = true. No numbers should be involved here.

Right, but elem.checked = 1 works too, isn't it? No matter, it's fixed now.
