回答1:

Without even seeing code, my gut tells me that you have a trailing comma somewhere inside an array or object literal. IE will choke on those with the Object expected error, usually at line 1 (which is meaningless).

Something like this:

var something = [
  "val1",
  "val2",
  "val3",
  "val4",
];
      ^^^^^

Install IE9 and pray it produces the same error. Press F12 to open the developer console which is somewhat capable of doing useful debugging.

Have fun.

You can install 'IEDeveloper' tool onto IE8 or IE7 (i guess you will not using IE6, if you are not lucky enough :)), and debug the page and that will show the exact location where the problem is , shortcut F12
