Adding TextBox to FrameSet/ Frame

Hy Guys :D I was helped here a few days ago and i need help now  too :/

the problem is ..

I'm using C# to create my bho to add Jquery to Website ( I can't change the website by the programmer-side  ( can't modify the website but the website have Jquery Lib :D yes <3  ) 


Here come the problems :

The website doesn't have <body></body>
Just have <html><head><title><form><frameset id ="fs" ><frame id=frmMenu><frame id="frmMain"><noframes/> and that's it ...

soo how can i add this textbox code ...

  1.   $('<input type="text" id="PartNumberTextBox">').appendTo('body');
  2.   $('#PartNumberTextBox').css('position','absolute');
  3.   $('#PartNumberTextBox').css('right','6');
  4.   $('#PartNumberTextBox').css('top', '435');
  5.   $('#PartNumberTextBox').css( "width", "+=280" );
  6.   $('#PartNumberTextBox').css('background-color', '#000494');
