How to cause button click event when enter is pressed in an hta application

问题

I have a script that allows me to hide a folder on my pc (using batch file). I've just implemented an hta application to it for the password so It's more seccure. Now the problem I'm having is that if I want to press enter to submit the form on the hta application, it just clears the password field and does nothing. I would like it to have the same effect as if I were to push the OK button. This is the hta part of my batch file:

:HTA
    <html>
    <head>
    <title>Password Entry</title>
    <hta:application id="htaid"
    applicationName="Password"
    border="thin"
    borderStyle="normal"
    caption="yes"
    contextMenu="no"
    maximizeButton="no"
    minimizeButton="yes"
    navigable="yes"
    showInTaskbar="yes"
    singleInstance="yes"
    sysmenu="yes"
    version="0.1">
    <script language="vbscript">
        window.resizeTo 210, 110
        Sub SaveBatch()
            set fs=CreateObject("Scripting.FileSystemObject")
            strFile=fs.GetAbsolutePathName(fs.BuildPath(fs.GetSpecialFolder(2), "UserIn.bat"))
            set ts=fs.OpenTextFile(strFile, 2, True)
            ts.WriteLine "set PASSWORD=" & document.Forms(0).elements("password").value
            ts.Close
        End Sub
    </script>
    </head>
    <body>
    <form style=margin-top:-15;>
        Password:
        <br><input type=password name=password>
        <br><input type=button language="vbscript" value="OK" onclick="SaveBatch : Window.Close">
    </form>
    <script language=vbscript>
        document.Forms(0).elements("password").focus
    </script>
    </body>
    </html>

I've tried creating a method that checks for keycode 13 onkeypress, also tried implementing it into the html portion of the password field. It either does what it did before, or causes a script error.

Try my modification code and tell me if this did the trick or not ?

<html>
<head>
<title>Password Entry</title>
<hta:application id="htaid"
applicationName="Password"
border="thin"
icon="wlrmdr.exe"

contextMenu="no"
maximizeButton="no"
minimizeButton="yes"
navigable="yes"
showInTaskbar="yes"
singleInstance="yes"
sysmenu="yes"
SCROLL="NO" 
SHOWINTASKBAR="Yes"   
SELECTION="no"
MINIMIZEBUTTON="no"
