I'm going to implement logout button in my PhoneGap application, which will return the user into authentication page (with cleared fields). For the button I'm using anchor with onclick event:

<script type="text/javascript">
function doLogout() {
    var backlen = history.length;
    history.go(-backlen);
    window.location.replace("index.html");
}
</script>

<a data-role="none" href="#" onclick="doLogout"></a>

but it's not works, i.e. it's just returns me to that authentication page with already filled fileds, seems like just a one step back. I'm not sure for history.clear(), because googling it gave me nothing:

<a data-role="none" href="index.html" onclick="javascript:history.clear();"></a>

Could anyone advise me where is my problem? If there is another solution to handle logout event in PhoneGap I would follow it. THanks
