Question

I am a newbie at jQuery. I was trying some things but I need some help.

I have the following script

jQuery(function($){
        $("#query").whatever({
          parameter1: 32,
          parameter2: 4,
          query: "something"
        });
      });

I need a script to change query: "something" to query: "something else" by a submit form. Is it possible?

ps: i change $("#query").something to $("#query").whatever to dont confused with the parameter query: "something"

Actualy i use jquery code from http://tweet.seaofclouds.com/ I want to change the “query” parameter in example 2 as i told before, by a submit form.

take a look at : http://api.jquery.com/jQuery.extend/

with a form :

    <form>
        <input name="newvalue" id="newvalue" type="text"/>
        <input type="button" id="onclickUpdate" value="update" name="update"/>
    </form>
    <script>
        var obj = {
            parameter1 : 32,
            parameter2 : 4,
            query : "something"
        };
        $(function() {
            $('#onclickUpdate').click(function(e) {
                e.preventDefault();
                console.log('old : ' + obj.query);
                $.extend(obj, {
                    query : $('#newvalue').val()
                });
                console.log('new : ' + obj.query);
                $("#query").something(obj);
            });
        });
    </script>
