Re: select and modifie checkboxes

$$("input[type=checkbox][name*=part_of_the_name]").each(function(c) {
c.checked = false; });

the name*=part_of_the_name will select any checkbox with
''part_of_the_name'' anywhere inside the checkbox. If you use
name^will only check at the beginning, $= only checks at the end, and the
equals sign only will match exactly the name you selected.

Best,
-Nicolas

Re: select and modifie checkboxes

You can use [id=myId] or #myId inside the selector. Check a CSS 3
selectors reference, and use the SelectORacle
(http://gallery.theopalgroup.com/selectoracle/) to debug your
selectors :)

when you do $$(...).each(function(c) { ... }) the parameter passed to
that anonymous function is the checkbox ("each" iterates over an
enumerable passing every element to a function, read it on
http://prototypejs.org/api/enumerable/each ).

If you want to check whether the checkbox is already checked you can
check the ''checked'' property on the checkbox (sic) //=> if
(c.checked)
{ ... }

If you want to find all checkboxes that are checked, you can use
Enumerable.select:

$$("input[type=checkbox]").select(function(c) { return c.checked })

Which will return the "filtered" array of all those items that return
true on the iterator. Again, see the API at
http://prototypejs.org/api/enumerable/select

If you need to do something different for the first item, you can use
the second (optional) argument passed to each/select/etc which is the
current index.

$$("input ....").each(function(checkbox, index) {
 if (index == 0) {
   // first checkbox
 }
 ...
});

Best,
-Nicolas

Re: select and modifie checkboxes

Hello,

i change the code a little bit to

var CheckboxTools = {
   toggle: function(seriesID) {
       var boxes =
$$("input[type=checkbox][ID^="+seriesID+"]");
       if (boxes.length) {
         var toState = !boxes[0].checked;
         boxes.each(function(box) {
           box.checked = toState;
         });
      }
   },
   getCheckedValues: function(seriesName) {
     return
$$(''input[name="''+seriesName+''"]'').inject([],
function(memo,
box) {
       if (box.checked) memo.push(box.value);
       return memo;
     });
   }
};

the toogle is working now:) For general . Is this a class and the toogle 
  functions?

Re: select and modifie checkboxes

Which function are you talking about?

Use the :checked pseudo-class in getCheckedValues.  (This also gets  
around the problem that you''re not initializing memo for each call,  
so you''ll get dirty data.)
getCheckedValues: function(seriesName) {
      return
$$(''input[name="''+seriesName+''"]:checked'').pluck(''value'');
    }

... and, you may want to try a lower-case "id" in toggle().
