Form is submitted twice on IE only

Question

I have a jsp login form page,which uses stripes:submit button to call ActionBean method as well as an OnClick() javascript function on the stripes:submit button to submit the login form. In this scenario, the IE8 browser sends the request twice. It works fine for other browsers like FF and Chrome.Is there any way to prevent it.

Thanks in advance for yours assistance.

Regards,

NM
