if ( bValid ) {
processDetails();

Ajax can do this. Google it, and check out api.jquery.comand look at the ajax functions, .ajax(), .post(), .get(), .load(), etc.
Ajax 可以做到这一点。谷歌一下，查看api.jquery.com并查看 ajax 函数，.ajax() 、.post() 、.get() 、.load() 等。
As for your specific question, here is what you would do:
至于你的具体问题，这是你会做的：
//Javascript file
$("input[type=checkbox]").click(function () {
$.post('my_ajax_receiver.php', 'val=' + $(this).val(), function (response) {
alert(response);
});
});
//PHP file my_ajax_receiver.php
<?php
$value = $_POST['val'];
echo "I got your value! $value";
?>
