javascript - An input in a form named 'action' overrides the form's action property. Is this a bug? -


i have form marked 

<form class="form1" method="post" action="form1.php" style="width:405px">

ordinarily, access action of form in javascript referring .action of form object, example

document.forms[0].action

which return value

form1.php

however, if have, component of form, item named "action", "action" becomes content of form's action. is, if form markup contains, example, 

<input name="action" type="hidden" value="check" />

then 

document.forms[0].action

returns value 

<input name="action" type="hidden" value="check" />

now, did work out how around this: using 

document.forms[0].getattribute("action")

however, it's nasty gotcha confused me long. bug? known gotcha of dom management? or should habit of using .getattribute()?

i not call bug. effect occurs, because attributes can read using element.attributename , named inputs inside form can accessed in same way, formelement.inputname. if there attribute , input same name, there no guarantee 1 used. behaves differently in different browsers.

i use getattribute if reading known attribute included in markup or added using setattribute in javascript. dynamic values like, example, checked attribute of checkbox, don't use getattribute. more question of personal preference, guess.

Java, Hibernate, MySQL - store UTC date-time -

i saw here on few related questions (like this one , of course, this one )... essentially, want store date-time utc, , let application user choose time zone wants display date-time in. since seems date-time fields affected underlying jdbc driver, wonder if acceptable way go storing utc date-time: set both mysql , application server machine utc time zone (no need separate) both mysql , jvm should pick underlying system time settings (if not instructed otherwise) use datetime table columns on mysql side use java.util.date corresponding mapping on hibernate side (i guess java.sql.timestamp used too) let application worry interpreting date-time fields - i.e. let user choose preferred time zone is ok? edit clarify - here meant refer timestamps created strictly on server (e.g.date-time of record creation). application server instantiates date objects (new date() equals current date-time on server, , time zone agnostic). if client user wants supply date searching/filte...
