开发者_开发百科guys, I got the error XMLHTTPRequest is Undefined in IE6 when I load data via ajax to another drop down in php.

Most probably that's because in IE6 you'll have to create XMLHTTPRequest with ActiveXObject,

Like so:

   var xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");

IE6 has no native support for XMLHTTPRequest however XMLHTTP is implemented as an ActiveX object provided by MSXML.
