I've this simple form:

<form id="commentForm" method="POST" action="api/comment">
    <input type="text" name="name" title="Your name"/>
    <textarea  cols="40" rows="10" name="comment" title="Enter a comment">
    </textarea>
    <input type="submit" value="Post"/>
    <input type="reset" value="Reset"/>
</form>

I need to add two POST parameters before send to the server:

var params = [
               {
                 name: "url",
                 value: window.location.pathname
               },
               {
                  name: "time",
                  value: new Date().getTime()
               }
             ];

without modifying the form, please.

To add that using Jquery:

$('#commentForm').submit(function(){ //listen for submit event
    $.each(params, function(i,param){
        $('<input />').attr('type', 'hidden')
            .attr('name', param.name)
            .attr('value', param.value)
            .appendTo('#commentForm');
    });

    return true;
});

you can do this without jQuery:

    var form=document.getElementById('form-id');//retrieve the form as a DOM element

    var input = document.createElement('input');//prepare a new input DOM element
    input.setAttribute('name', inputName);//set the param name
    input.setAttribute('value', inputValue);//set the value
    input.setAttribute('type', inputType)//set the type, like "hidden" or other

    form.appendChild(input);//append the input to the form

    form.submit();//send with added input
