required =

（'< div > < / div < span class =code-keyword>> '）。dialog（{
autoOpen：false，
title：'Required Information'
}）;
}）;

< / script >

('<div></div>').dialog({ autoOpen: false, title: 'Required Information' }); }); </script>

<script type="text/javascript">

function validate_login ( )
{
    valid = true;

        if ( document.login.user.value == "" )
        {
