How to determine which livevalidations have failed when a form is submitted - livevalidation

I'm using LiveValidation in a tall form (so some of the form has scrolled off the top of the screen when the user clicks the submit button at the bottom of the form).
The user may not have visited every field on the form so may not have seen validation failures for "Presence" whilst filling in the form.
If the validation triggered by submitting the form fails, I'd like to determine which fields failed (so that I can set focus to the first field that failed validation so that it is visible to the user).
How can I determine which fields have failed validation? The answer is probably obvious, but it escapes me at the moment.

processing html form partway through

Previously, I have seen web forms that are multiple pages long, but on each page, if the inputted information is invalid, it will cause an error and make the user fix their input.
However, I can't seem to find anything to show me how to do this. My form is 2 pages, with a Continue button at the bottom of the first and a Submit button at the bottom of the second. However, all possible errors generated will be on the first page, so I want it to show them if the user hits Continue when he has inputted errors.
Right now, the form is only processed after the user hits Submit and all the data is posted to the backend, which means it then has to go back to the first page to show the errors.
You could try to check the information every time the user continues to the next input control, and tell him that there's something wrong if he enters any nonsense.
How to achieve this depends on how your form looks:
Does it just contain and something like that or radio buttons and other "special elements"?
For you could check at the FocusLost event, but I don't exactly remember its syntax.

Inline validation technique, how to validate the LAST input in a form?

Much thought has already gone into practices around validating the user input in a form. I have a programming question about the "inline validation", also called "onblur validation". (A research article about the benefits of inline validation can be found here).
Let's say I have a very simple form with 5 inputs and 1 submit button at the bottom. The user focusse on the first field first. After pressing tab or manually clicking on it, he goes to the second input. This triggers the validation of input field 1. Depending on the techniques used, this might take a few seconds (for example, if a server postback is required to truly validate the field).
MY problem lies with the last field. User will be expecting to see the inline validation after they're done. But users do generally not tab if the next ui element is a button instead of yet another input element. Thus, the onblur validation will not trigger and the user gets no feedback, which they might mistake for erronous input. If they manually click on the submit button, the validation will trigger... but it will also trigger the total form submit, likely leading to another page if all is valid. Now, some users might be smart enough to realize this is onblur validation and they should "click anywhere" to trigger the validation, but I can't really count on that.
I thought of one solution: using the keypress event instead of the onblur event for the last input field of a form. However, the article cited above states it is better to avoid this kind of validation. It would also drastically increase the amount of validation to be done (one time for every keypress)
What are your thoughts on trying to mimic the nonexistant event "user stopped typing but did not focus out of input element"? Can it be done by combineing the keypress event and a timer? (Like, if user did not type anything for 2 seconds, then validate?)
var typingTimer; //timer identifier
var doneTypingInterval = 2000; //time in ms
$('input[type="email"]').keyup(function(){
clearTimeout(typingTimer); //reset the timer
typingTimer = setTimeout(validateEmail, doneTypingInterval);
});
Change validateEmail to the name of the function that validates the email input.

Best usabilty with an editable data grid and other form fields on same page

I am creating a page and the page has an editable data grid (I'm actually using jqgrid). The user can add, delete, and edit the rows of the grid. There are also some other form fields on this page such as text boxes and drop downs, but they are not part of the grid.
From a usability perspective which of the options do you think is best and why?
User manages the grid separately from the rest of the page. This means that there is a save button on the grid. So the user can save a grid row to the db without clicking the submit button. When the submit button gets clicked, the non-grid form fields get sent to the server.
user manages grid and other fields dependent upon each other. This is like an "Everything or nothing scenario." When you click the submit button, all of the form fields get submitted an saved the db along with the grid fields. If there is a validation error, nothing gets saved.
If there is a better way to handle this type of situation that I did not list, please let me know.
What I was thinking when I was in a similar situation, is how important it's that the user fills the other form fields. If they are optional and the grid is more important I would have the submit button in the grid but if I want the user to fill all the fields, the button should be at the end. In the case where the button saves the whole form, you can have a type of warning if the user skips some fields or you can have a deactivated button.
The second thing I thought was the height of the page. If the button hides 'above the fold' there is a high posibility that some users won't see it and the data won't be saved. So in that case, maybe you should have it in the grid. I would check analytics about screen resolutions.

Best way to do a 'Confirm' page?

I was wondering about the best way to implement a "Confirm Page" upon form submission. I know that it's best for the script that a form POSTs to be implemented by handling the POST data and then redirecting to another page, so the user isn't directly viewing the page that was POSTed to.
My question is about the best way to implement a "Confirm before data save" page. Do I
Have my form POST to a script, which marshals the data, puts in a GET, and redirects to the confirm page, which unmarshals and displays the data in another form, where the user can then either confirm (which causes another POST to a script that actually saves the data) or deny (which causes the user to be redirected back to the original form, with their input added)?
Have my form POST directly to the confirm page, which is displayed to the user and then, like #1, gives the user the option to confirm or deny?
Have my form GET the confirm page, which then does the expected behavior?
I feel like there is a common-sense answer to this question that I am just not getting.
If you must do this (I'd only do it for stuff involving monetary transactions or the like, personally), I'd recommend 2 resources/URIs, both of which follow the Post-Redirect-Get pattern: POST the initial cart checkout, create a "pending order" state (or similar), redirect to the page for that state. The user can then POST from that page to the next URI to create a "confirmed order" (or similar), which redirects to a receipt page or whatever.
What I've done in the past is have one page that has a 'View' area with labels and then a 'Edit' area with textboxes/dropdowns/etc. You can make them DIVs or TABLES depending on your preference.
User comes to page and gets the edit view so they can use the textboxes. Save/Submit button at the bottom.
Clicking on Save/Submit does a postback, populates the labels with the data they entered, and allows them to view/verify what they entered. Continue and Edit buttons at the bottom.
Edit is a postback and goes back to the edit view.
Continue does the actual save and redirection to a new page that displays the confirmation.
Optionally you could save the data on the confirmation page instead of the first page depending on your preference again.
Actually, you could do this ahead of the submit. In the form submit (wherever that is) add an onlick that fires a modal window with a confirmation button. My personal favorite in this situation is to use a Jquery UI Modal Confirmation dialog.
I personally fire this via means of a Jquery .click statement in the page.
So, the document won't submit until the onclick dependency has been completed and changed to "true" which the example does automatically with the included "ok" button.
I believe that this will gracefully fallback to just not require the confirmation if Javascript is turned off, which itself is becoming more and more of an "edge" case. In fact, some of my most staunch corporate clients are starting to accept limitations such as this case when Javascript is turned off....and they're way more picky that most any of us ever will be.
Then, you're free to submit to any page you'd like. Personally, I've switched all of my forms over to a Jquery .ajax submit, but that's just me. You can do it however you like.

Do all browser's treat enter (key 13) the same inside form?

I have a form with multiple submit buttons, each of which is relevant to how the user wants the data saved and/or loaded.
The problem is (or was) that if a user pressed enter on the last (or any other) input within the form, the submit button that seemed to be called was the "load saved formed" which is at the top of the form. All attempts to user javascript to have the return button default to the "save form" seemed useless, almost as if the browser was too busy already submitting the form to have any js interfere.
Finally, in FireFox 3.5, I actually had the server-side script echo out what it received for the post variable and discovered that none of the submit button values were being passed back to the server. As it turns out, I have hooks in the script for when the user hits "Save" or "Save and Print", etc, but if the user uses the "load page" it simply updates a variable and continues loading the page normally with that variable in context.
So with no submit button value at all, it did the same thing, it simply loaded the page.
So, on to the big question:
Is this typical browser behavior? Maybe even reliable browser behavior? Will hitting enter always submit the form as though no submit button was pressed at all, or do some browsers like to pick a button to use as the default when the user presses enter?
If it is typical behavior, what is the suggested course of action? I was going to have the script save anything no matter what, so long as there was data in the form, but then I realized that this was even more dangerous, because if the user loads one saved form, changes there mind, and changes the form dates and hits "Load Form", then it will save the form data from the pervious form for the new dates they have requested.
I considered setting it up so that changing the load form inputs (selects with dates and other particulars) would clear the form so that the server still recieved an empty form and thus would not overwrite any previous data, but this is risky as well, as many users will certainly notice and think that their data has been lost, etc, and there is always the slight chance that the user will be almost done with the form, go up to the top and fiddle with the form-load selects just to confirm they chose the right what nots and then be forced to start from scratch.
I should just have two forms, one for loading, one for the data, but the problem with that is that all of the data in the load part of the form does get used by the main form. I could write more js to combine the two on submit, or hide the data in the second form, but all of that seems clunky.
Essentially, I need a setup such that the top part of the form is independent of the main form, but not vice versa. Submitting the upper form does not submit the lower, but submitting the lower does submit the higher.
Okay,I've gone on long enough. Basically I'm wondering if a solution already exists or if anyone else has run into this and found a clever fix. I thought simply having the form save whenever the form wasn't empty was pretty clever, until it occurred to me that when the user goes to the page, it auto-loads the most applicable form given the date, and thus changing the load variables will almost always caused trouble.
Having read the possible duplicate that Artelius was good enough to draw my attention to, I'm still unclear on the consistency across browsers regarding the Enter button as submit.
It seems that almost everyone in that question assumed that hitting enter presses the first available submit, which was also my assumption until a friend suggested I hide (via CSS) another submit button at the top of the form with whatever I wanted enter to achieve. It was when this got me the same results that I finally viewed what was being passed to the server (ie nothing in terms of a submit value). So that means either
a) the "enter as no submit button just submit" is new behavior for some or all browsers,
b) the "enter as just submit" vs "enter as first submit button" is just browser choice, no trends, just typical cross-browser unreliability, or
c) Everyone just keeps assuming that the "enter as first submit button" is the case because most of us only code if (situation1) else (assume not situation1) and none of us are really sure what the browser is doing.
I highly doubt it's that last one, but then again, I also highly doubt most of us know which browsers do which. I'd sure like it if there was a straight answer I could pass along.
Oh, and finally: While I know it would be far simpler to use buttons, and I am taking that under serious consideration, I would also like to consider other options, since really the only need for less submit buttons I have is for when users hit enter instead of one of the buttons.
Actually, let me get carried away one more second:
The only thing I really need to know is whether or not they hit enter FROM one of the text inputs. If I could pass that along to the server, I'd know if I should save or reload the form. But the problem is (or at least what I've had troubles with) is that when the user hits enter in an input, it seems like there isn't any more playtime with js to capture anything, and in some cases, it seems like the browser is triggering the onclick for whichever submit button and thus not really allowing me to know the real event that triggered that. I'll play around more with jquery, but has this behavior been observeed by anyone else?
My best advise would be to only have on submit button, and let that submit what ever is the most common usage of the form. Let the rest of the buttons just be normal buttons, which you can hook click events onto.
Just make sure you make it very clear which button will be "pressed" when the user hits enter. Let the submit button be the biggest one. If you have 3 buttons that are used equally as much, I would just drop having a submit button at all...
edit: I'm pretty sure most browsers will post all the data inside a form. If you want to do some checking on the data before posting you could add a listener for onsubmit
<form onsubmit="checkData(this);" ... >
Passing in this will let you check which form is actually being submitted:
function checkData(form) {
var formName = form.id;
//check all the data based on which form is being submitted
}
The HTML5 spec specifies synthetic click activation steps for implicit form submission:
A form element’s default button is the first Submit Button in tree order whose form owner is that form element.
If the user agent supports letting the user submit a form implicitly (for example, on some platforms hitting the "enter" key while a text field is focused implicitly submits the form), then doing so for a form whose default button has a defined activation behavior must cause the user agent to run synthetic click activation steps on that default button.
