Scripting can't call javascript function before submit form

I want to test my application by script, I wrote a script to login as below:

// load the account name and password
loadVariables accounts.txt

// bring up the login screen
setDOMElement name=user_id
navigate http://w3x32s05-pv010.pd.local

// log in
sleep 5
setValue name=user_id %ADMINISTRATOR%
setValue name=password %PASSWORD%
setDOMElement innerText=My Institution
sleep 5
submitForm name=login

It runs well but just couldn’t login successfully.
After I debug code, I found the root reason is because the submitForm action won’t run validate_form javascript funciton in my login page before submit(it will call the function if we submit it by manual).
my form is like this:

the validate_form javascript will encode the password by a token value, it means the encode password will change each time, I can't set the encode password value too. Does it has any way I can write the script to login in my application? thanks.

Try sending a click (sendClick) to the form submit button instead of submitting the form itself.

Thanks very much, I can run the script complete successfully now.

I am testing login into live id and sign out. I am not able to login at all. After login page, I don’t see it entering userid and pwd and submit. Please help fix my script.

sleep 5
setValue name=login
setValue name=passwd test
sleep 5
sendClick id=idSIButton9
