Well, this has nothing to do with prototype, but you might use
Prototype's Ajax.Request[1] to send only the data from the checked
input (as follow):
e.g.:
<form name="myform" method="post">
<input type="checkbox" name="choice" value="1" onclick="myMubmit(this);">
<input type="checkbox" name="choice" value="2" onclick="myMubmit(this);">
<input type="checkbox" name="choice" value="3" onclick="myMubmit(this);">
</form>
function myMubmit(input) {
new Ajax.Request(url, {
method: 'post',
parameters: input.name +'='+input.value,
onSuccess: function(r) {
// show the result or do something wild
}
});
}
You can also use Prototype's Event.observe[2] to check the click event
on each checkbox.
