pass extra paprameter with serialized form in jquery

Question

In the following example am submitting a serialized form using post method. Its working fine now. But I want to pass some more extra parameter to the submitted page. How to pass that value to the form. I dont like the way to keep that value in a hidden field in that form. Is there any other way to do this?

var postUrl = 'myphppage.php';

$.post(postUrl,
    $('#myForm').serialize(),
    function(response) {    

        if(response.status){
        //do something
        }else{
        }

    },'json'
);

Answer 1

Just add simply like how you do string concatenation. For eg., you wanna add a parameter, username with the value praveen, you can do this way:

$.post(postUrl,
    $('#myForm').serialize() + '&username=praveen',
    function(response) {    
        if(response.status){
            //do something
        }else{

        }
    },'json'
);

But just make sure you URLEncode the values and keys.
