Cannot select tags with ids containing periods

$('#some.id') will not match a tag with an id of "some.id" even though it's valid HTML according to  http://www.w3.org/TR/html4/types.html#type-name

Updating quickExpr on line 38 of jquery-1.4.2.js to add the period to the regex fixes it for me: quickExpr = /[<]*(<[\w\W]+>)[>]*$|#([\w.-]+)$/

I guess to agree with the spec it should also include colons and underscores.

$("#some.id") Matches an id of "some" with a class of "id", just as it does with CSS selectors. If you want to make your life hard and use ids with dots, you'll need to escape it with a backslash. Since Javascript uses backslash as an escape as well, you have to use two backslashes in the string.
