In the url instanced below, unless I'm misunderstanding what you are
trying to do, if you make a properly formed POST direct to
someurl.htm?loadpage, direct from a script or a stack for instance, the
onSubmit event in the html form is almost certainly irrelevant, because
it is only triggered in the browser when the user clicks the submit
element, and wouldn't apply in other cases.
Have you experienced some issue that makes you think it is relevant?
if something is wrong with user input or whatever, but you would bypass
that by POSTing directly to the action url.
headers before it allows the POST action, and that might conceivably be
relevant to it being accepted as valid by the action url. But it isn't
very likely and in any case you should be able to figure the details out
Any serious validation will invariably be done by the script the data is
validation (pre-validation) is really only useful for catching obvious
data entry errors for purposes of user-friendliness.
