Hi,
I have a variable number of checkboxes in a form. I have developped a simple
function to calculate a number whith the quantity of checkboxes checked. I
put de JS function in onChange or in onClick whith the same problem:
Function don't execute but after checkbox clicked loses his focus and,
sometimes, if you click in another checkbox inmediatly after a first one,
don't execute the function at all, and I lose information. Any ideas of what
can be the problem?
Thanks for your interest.

Sorry, I suposed that the code wasn't important for this problem, because,
the code does the expected, but only sometimes the event executes it. Here
goes:
function newImport(document,boolean_canvi,cost)
{
var texteImport = docu.getElementsByName("import_texte");
var cost2;
if(boolean_canvi)
cost2= parseFloat(cost);
else
cost2= parseFloat(cost) * (-1);
texteImport[0].value = (parseFloat(texteImport[0].value) + cost2);
}
I call the function on
<input type="checkbox" onChange="javascript :
newImport(document,this.checked,1.00);" /> //The number 1.00 is an example.
In my code is a PHP variable.
Thanks

I guess the following may help a little:
-----------------------------------------------------------
<script>
function show_click(o)
{
document.getElementById('t1').value+="\r\nonclick fires: "+o.checked;
}
function show_change(o)
{
document.getElementById('t1').value+="\r\nonchange fires: "+o.checked;
}
</script>
<input type=checkbox onclick='show_click(this)'
onchange='show_change(this)'>
<textarea id=t1 rows=20 cols=50></textarea>
----------------------------------------------------------
The test code shows the onchange event never fires at the 'input
type=checkbox' object.

Thanks, I see that onClick is the event I'm looking for, however as you can
note, if you clikc two times too fast, it loses events :(

I dont think so.
Man handing a mouse can not faster than computer, never! :-)
even you focus on the selectbox and press ENTER (this will fire onclick
event as well), the computer still faster than you, nothing will be losed.

I dont think so. Man handing a mouse can not faster than computer, never! :-)
I *do* think so, in this instance.
Two very quick mouse clicks are translated into a doubleclick.
The sequence of events is:
onmousedown, onmouseup, onclick, onmouseup, ondblclick
There is only one onclick event. The second "onclick event" is translated
into an ondblclick so the second "onclick event" appears to be lost.
The OP should handle ondblckick events.

Richard.
I do agree with the ondblclick part.
The page interface should notice the users what's happenning due to their
operation so that they can re-click or something to get the right result. I
mean the page should display the results somewhere, otherwise there always
have troubles.

Thanks for your answers. I'll try with onDoubleClick event. I'm allways
learning :-)

It is because that double-click is handled by a different event handler,
called "ondblclick". You can probably use event-bubbling in those UAs:
function form_ondblclick(e)
{
var t = (e && e.target || event.srcElement);
(t.click
? t.click(event)
: t.onclick
? t.onclick()
: void 0);
}
<form ... ondblclick="form_ondblclick(event)" ...>
Note: This is partly using proprietary behavior. There is no "dblclick"
event in the W3C DOM Level 2 Events Specification or a [on]click()
method, only an "ondblclick" event handler attribute in the HTML 4.01
Specification.
