What you need to use is <%= ... %>. Try using this:
您需要使用的是<%= ... %>. 尝试使用这个：
<script type="text/javascript">
window.onload = function(){
<%
String res = request.getParameter("Message");
%>
var Value = <%=res%>;
alert(Value);
document.Form.submit();
};
</script>

@John Why you creating scriptlet tag inside javascript. Instead try using this,
@John 为什么要在 javascript 中创建 scriptlet 标签。而是尝试使用这个，
<%
String res = request.getParameter("Message");
%>
<script type="text/javaScript">
window.onload = function(){
var Value = "<%=res%>";
alert(Value);
document.Form.submit();
};
</script>
else try using jquery plugin for your purpose,
否则尝试使用 jquery 插件来达到您的目的，
<%
String res = request.getParameter("Message");
%>
<script type="text/javaScript">
$(document).ready(function() {
var Value = "<%=res%>";
alert(Value);
$('form#myForm').submit();
});
</script>
