Calling JavaScript func

[samear]

Hi,

I can no longer using the following script to log into our site because we use JavaScript functions instead.

logData 0
setValue id=username user1
setValue id=password password
submitForm name=loginForm

How would I put the following line in wpt scripting?

document.getElementById("__input1-inner").value = "username";
document.getElementById("__input2-inner").value = "password";
document.getElementById("loginForm").submit();

Thanks,
