jQuery merge objects and json_encode

How can I merge properties of two JavaScript objects dynamically?

I am trying to merge two objects in jQuery.

first object:

var rules1 = {  
    firstname: { required: true, minlength: 3 },
    lastname: { required: true, minlength: 3 }
};

second object:

var rules2 = {  
    test1: { required: true, minlength: 3 },
    test2: { required: true, minlength: 3 }
};

I want the result to look like this:

var merged = {  
    firstname: { required: true, minlength: 3 },
    lastname: { required: true, minlength: 3 },
    test1: { required: true, minlength: 3 },
    test2: { required: true, minlength: 3 }
};

I also need to know how might look like the PHP array for rules1, because this object will be tranformed with json_encode function.

These are objects, not arrays. In PHP you just create an associative array: `$arr = array('firstname' => array('required': true, ...))`. Read more about arrays in PHP: http://php.net/manual/en/language.types.array.php — Felix Kling, Oct 12 '12 at 08:33

You can merge them doing this:

var merged =  $.extend(rules1, rules2);

If you want build it from php your object will be:

$rules = new stdClass;
$rules->test1 = new stdClass;
$rules->test1->required = true;
....

Personally, in PHP I prefer to work with arrays. Then they can be converted to stdClass recursevely by using some custom functions. You can find one of these here:

There is no need to use `stdClass` here at all.. – Felix Kling Oct 12 '12 at 09:04 — Felix Kling, Oct 12 '12 at 09:04
