There was a problem that an invalid pointer error occurs.

The error occurs only in IE.

The error did not occur in the same script in Firefox and Opera either.

The problem seems to occur in the following parts when it is

[[e.className ==""]].

src/jquery/jquery.js

has: function(e,a) {

if ( e.className )

e = e.className;

return new RegExp("(^|\\s)" + a + "(\\s|$)").test(e); <-- Error

occures in this line.

I was able to correct it with the following patches.

+ if ( e.className != undefined )

e = e.className;

return new RegExp("(^|\\s)" + a + "(\\s|$)").test(e);

}

Could you confirm it?
