<script type="text/javascript">
<!--
       var singupFormJson = {
                rules:
                {
                    firstname: { required: true }
                },
                messages:
                {
                    firstname: { required: "姓氏不能为空" }
                },
                messagesAlert:
                {
                    firstname: { required: "用户名不能为空" }
}
}
            var singupFormJson1 = {
                rules:
                {
                    firstname: { maxlength: 5 }
                },
                messages:
                {
                    firstname: { maxlength: "姓氏最多5个字符" }
                }
            }var Extend = function (destination, source) {
for (var property in source) {
var copy = source[property];
if ( destination === copy ) continue;
if ( typeof copy === "object" ){
destination[property] = arguments.callee( destination[property] || {}, copy );
}else{
destination[property] = copy;
}
}
return destination;
};
Extend(singupFormJson, singupFormJson1); for(var i in singupFormJson){
for(var j in singupFormJson[i]){
for(var k in singupFormJson[i][j]){
document.writeln(singupFormJson[i][j][k] );
document.writeln('||');
}


}
document.writeln('<br/>')
}//-->
</script>

如果使用jQuery
  singupFormJson = $.extend(true, singupFormJson, singupFormJson1);
