Metasearch - Help with Jquery ajax request when checkbox is pressed

I want to make a Jquery ajax request when a checkbox pressed either true or false.

My form:

<form method="get" action="/" accept-charset="UTF-8"><div style="margin: 0pt; padding: 0pt; display: inline;"><input name="utf8" value="✓" type="hidden"></div>        
    <div class="menuitem">
    <label for="search_compan开发者_JAVA百科y1">company1</label>
    <input name="search[company1_is_true]" value="0" type="hidden"><input id="search_company1_is_true" name="search[company1_is_true]" value="1" type="checkbox">
    </div>
    <div class="menuitem">
    <label for="search_company2">company2</label>
    <input name="search[company2_is_true]" value="0" type="hidden"><input id="search_company2_is_true" name="search[company2_is_true]" value="1" type="checkbox">
    </div>
    <div class="menuitem">
    <label for="search_company3">company3</label>
    <input name="search[company3_is_true]" value="0" type="hidden"><input id="search_company3_is_true" name="search[company3_is_true]" value="1" type="checkbox">
    </div>
<input id="search_submit" name="commit" value="Create Search" type="submit">
</form>

This launches custom doAjaxRequest function after any of the checkboxes in menuitem class are changed to either true or false.

$('.menuitem input:checkbox').change(function(){
  doAjaxRequest();
})

Answer to first comment question:

$('.menuitem input:checkbox').change(function(){
      $('form').submit();
})

Though you probably want to define some id to your form and use it instead of just form selector: $('#formId')

EDIT I just made jsfiddle of your code in question and my second answer and it seems to work: http://jsfiddle.net/dUPmg/

Should be a fairly trivial task:

$('form input:checkbox').change(function() { 
    // $.ajax({});
    $('form').submit();
});

That would bind a change-eventhandler to each checkbox element. When the number of those elements increases, you should go for a delegated change-event instead.

$('form').delegate('input:checkbox', 'change', function( e ) {
    switch( e.id ) { 
        case 'search_company1_is_true':
             $.ajax({});
             break;
        case 'search_company2_is_true':
             $.ajax({});
             break;
        // and so forth
    }
});

$('form input:checkbox').bind('click change', function(){
    $.ajax({
      url: "/test.html",
      success: function(){
          $(this).addClass("done");
      }
    });
});
