I have a contact form with a similar setup to the "Ask a question" form here on Stackoverflow, a user will click a suggested link that will take them away from the contact page, on the new page they get to there is a link back to the contact page via:
Back
When the user returns to the page the previously entered values (e.g. name, email, question, message) are filled in correctly. How can I access those values from JavaScript? (using jQuery)
element.val();
^ Returns nothing as technically as far as firebug tells me there's no value actually entered. The browser is somehow filling the fields. I only need to access one text field in this case.
I think you can solve this with jquery session. https://github.com/AlexChittock/JQuery-Session-Plugin

There is a website that I do not have access to on the back-end that I go to monthly, type in my email address, check a few boxes and hit a submit button.
A while ago I found out You can append
?fieldname=value
to the end of the url to have it automatically fill that value into the field with that name. But is there anyway I can expand on this and fill in multiple values and hit the submit button?
Thanks!
Adding ?fieldname1=fieldvalue1&fieldname2=fieldvalue2 etc.. can add many more parameters send to the server.
Some website use those parameters in the page so when you add the good parameters, you will get the page with the modifications that those parameters did on it.
Is there a way to add a Back button which reloads a form with the inputs filled in?
I have a form with some input fields and a save (submit) button. When clicking submit, if the mandatory fields aren't filled in, a new page opens with a message. If I use the browser's Back button, I receive this message:
Confirm Form Resubmission
This webpage requires data that you entered earlier in order to be
properly displayed. You can send this data again, but by doing so you
will repeat any action this page previously performed. Press the
reload button to resubmit the data needed to load the page.
ERR_CACHE_MISS
So basically, it asks me to Refresh, and then confirm by clicking OK on a pop up window, after which the form reloads but with empty fields.
I have tried thinking of everything, but I can't find a solution. Thanks.
If it's possible, I would change the structure so that the form posts back to itself, and runs the validation of the mandatory fields. Then, if everything's ok, it will continue whatever processing is necessary. If there's a problem, it can show the form again, but in your code you will have access to the values already submitted, so you can pre-populate the form with these values and then display it to the user. It's a pretty standard design technique for this sort of thing.
What I wnat to build : (first I must say that I havent got any accounts on my web site) For example I have form with input field that every one can fills, after that you can submit form and if everything correct you will forwarded to another page !THAT CONTAINS! url for your filed form (previous page with form that you filled)
Easy explaine : You fills form then click submit button if all OK go to another page that contains button with url to your filed form (for example if you want to fix some data on it)
PROBLEM : How to build this, if I havent got users with their own form.
I have heard about tokens but never worked with them. What can I do ?
Can someone help me ? Forward me to the right way
I have a radio button field on a lotus notes form (say main form). If it is selected as "Yes", a link gets unhidden. On click of this link, another form opens up. If in the radio button, "Yes" is selected in the main form, the contents in the second form must be filled. So I need to write a validation if the radio button field is "yes" and the field inside the second form is not filled, then it should show a popup asking to fill the field in the second form. How do I get the value of the field in the second form on the main form for me to perform the validation?
You literally cannot do what you've described you want to do. The second (pop-up) form and its content no longer exist in the client (browser) context when you want to do validation on the first form's data. There are three possible ways to tackle the problem but only two of them are actually practical.
Let's dispense with the impractical method first. That would have the pop-up form write something back to its parent/opener, either as a JavaScript variable or as DOM content (a field outside of the Domino form or hidden element or some such) or, perhaps as a cookie value. Setting up the opener relationship reliably can be a problem cross-browser, but it is doable. The problem is that no matter how you do this, you have no guarantee that the value will be there when you need it (or expect it) except when the parent form is initially filled out. If the document is ever edited, you have no way of knowing whether or not the user has filled in the data on the pop-up. Anything you may have written to JS variables or the DOM during the initial session with the form only exist during the initial session. Cookies aren't permanent; they can be cleared by the user even if you try to give them eternal life via the expires value. No matter how you do it, you'd be telling anybody who has previously filled out the data you want that they need to fill it out again.
The second method would be to make a call back to the server to see if the pop-up form has been submitted and turned into a Notes document. That doesn't scale at all; even if everything is happening on a single server, there's no way to guarantee that the document you are looking for will have been written and indexed by the time you need it, and there is a time factor involved. If the user has already seen the validation nagging once, does what you tell them to do, and then gets the nag again, you're not making any friends.
The third method is to do everything you need to do on one form. (You can use CSS to do the pop-up if you're married to the pop-up idea.) And, you know, it really doesn't matter at all whether or not you would prefer to do it another way, it's the only way that will be reliable and make happy users. Yes, it will mean a little bit of extra work on your part. You're a developer - that's what you do for a living. You can even keep the structure of the existing application intact; WQO and WQS agents mean that you can glue documents together before sending them to your user, and pull them apart again before you save them. This is the only method that is guaranteed to be fast enough and reliable enough to be usable on the web.
[I did see the similar problems solved with AJAX/jQuery, so please read on].
I have a form that a user can fill out - but one of the options on the form allows selection of an image, and when the user goes to do that they are brought to a new page.
This was originally done via get, but my problem is... I need to save all of the information on the form to the session so that I can restore it when the user selects an image and goes back to the first page that had the form.
A HTTP GET may not hold enough data for all the information on my form, so I need to switch to post.
So, here's my problem... I need the form to POST to one page when I click "Select Image" and another when I click "Submit". How can I get the form to POST to a different page depending on which button was clicked?
PS: I'd prefer to just use standard javascript/html here. I plan on learning AJAX and moving over to jQuery after a while, but I'm not there yet :)
onclick, let each button call different functions. Within these functions, change the action attribute of the form dynamically.
document.forms['yourform'].action = 'your intended page';
Then submit the form.
document.forms['yourform'].submit();
