html() wont work on IR6 and 7, My codes are working well before then after i put some codes it stop working, The error says "unexpected call to method or property access", Then when i debug it, the error point to the line with appenChild() method. But im not convince, because i just add 50 lines of code i think, so when i trace back all my codes, i found the error were triggered when i use html(). Those line is to modify the page TITLE ( $("title").html("xxxxx") ), with some objects obj.html("xxxxxxx");
