[yekkala krishna]

Hi,

In my webapplication i am opening new window by passing some parameters.i am passing password also as parameter.But i need to hide it or encode it.
how can i do this.Following is my code:

function getUrl(gsamName,deviceName,userName,passWord){
window.open("./viewMapToolScreen.html?com.smarts.autoAttachDM="+gsamName+"&class=com.smarts.webapps.SmWebMapApp&com.smarts.launch.class=UnitaryComputerSystem&com.smarts.launch.instance="+deviceName+"&com.smarts.map.showAllBusiness=1&com.smarts.userid="+userName+"&com.smarts.password="+passWord);
}


function validate_form()
{
        valid = true;
        if ( document.map_form.contract.selectedIndex == 0 )
        {
                alert ( "Please select Contract Name" );
                valid = false;
        }

                getUrl(document.map_form.gsamName.value,document.map_form.devicename.value,document.map_form.userName.value,document.map_form.passWord.value);

       }
}

<input type="hidden" name="passWord" value=<%=session.getAttribute("GSAM_PASSWORD")%>></input>
 <input type="submit" name="submit" value="Show Map" class="button" onclick = "validate_form();"/>

You can post the form to the new window.

<form action="foo.jsp" target="submission" onsubmit="window.open('',this.target);return true;" method="post">
<input type="submit" value="Submit">
</form>

Do you think that this would give you any measure of security? What is the reason for wanting to hide the value?
