access webuijsf component with javascript

I have been trying everything written around and still cant get to be able to change a textField value with javascript...

If anyone knows a way, please help me...
i have tried both:
(hh is a dynamically added Hyperlink)
hh.setOnClick("document.getElementById('form1:textField1').innerHTML = 'ssfsdf';");
hh.setOnClick("document.getElementById('form1:textField1').value = 'ssfsdf';");

and none works...

Thnx a lot!!!
