Loggoff script for phonegap

I have a phonegap app built using html5, css3 and jquery. I am trying for a function where user clicks on a logou button and it takes to a login screen but with clear fields. I mean When I 开发者_如何学Gojust use the change page command and redirect it to login page, I stills ee the user name and password. I am simply using change page command:

function logoutbutton()

{

$.mobile.changePage("login.html");

}

What I should do so that when it redirects to login page, it clears the password field?

Not sure if this answers your question.. can you use pageshow or pagebeforeshow event handlers and set input (login/password) fields' value to "" ? Assuming you are using jquery mobile text and password type input fields in html?
