Back Button Not Maintaining Form Data
May 4, 2010
I have a form with three select boxes. Box 1 has a variety of choices, but boxes 2 & 3 are empty. When the person selects an option from box 1, box 2 gets populated with choices. When the person selects an option from box 2, box 3 gets populated with choices.
This is handled with javascript through either onblur or onchange (still working on which will work best for this).
The problem occurs after pressing submitting the form and then pressing the back button. All fields maintain their data EXCEPT boxes 2 & 3.
How do I get it so that those two boxes keep the data like the rest of the form?

I found this script for filtering data in a table:[URL]
However say I type something in the filter, I click a link on the page, and then use the back button...the form resets. Is there a way to prevent this/leave the table filtered?

I have a pageA containing a form the user my fill in partially. All data is stored into cookies. He follows a link to pageB that contains some of pageA.form inputs. If he adds or change form data cookies are instantly updated. What I need is if the user goes back (back browser button) to pageA, the form here is updated from updated cookies. Only Firefox 3 does the job without extra code. Ive tried all sort of things I found on the web with Opera 10, Chrome and Safari 3.

I use Spry for my form validation and have recently ran into a small issue. Form fields validated using Spry lose their value when I hit the back button. Fields without validation retain their values.
The form is using the POST method. With javascript, is it necessary to send the form variables back to the original form page?

I'm looking to have a lightbox pop up when a user clicks the Back button in their browser rather than just navigating back. The purpose is to ask a question with a Yes/No answer, and if they click No, I allow them to go back. The only thing I've found anything like this is the onUnload event, but that doesn't prevent them from going back. How should this be handled?

I am trying to write a script that uses the IF statement to see wether or not a user clicked the back button to come to a page, and then if it's true to not let the page load and kick them back X number of pages (say 4) This is what I have so far:
<script language="JavaScript"><!--
if javascript:window.history.back == 1
{
javascript:window.history.back(4);
return false;
}
//--></script>

I have a table with a load of stuff from a database. At the end of each row I have an edit and delete button. The delete button works magically, however I am trying to get the edit button to load data into a form above the table to be edited.
This is what I have so far.
$(".editbtn").click(function () {
if ($(this).attr("src") == "images/edit.png") {
$("#add").slideUp("slow");
$("#addform").slideUp("slow");
id = $(this).parents("tr:first").attr("id");
//Remove all selected classes .....
The data returned from the ajax request thingy looks like:
[["user_id","1"],["username","simpsonH"],["forename","Homer"],["surname","Simpson"]]
I want the user_id to go into the user_id input, username into the username input, etc. As you can see I have not started on this, I have just got it to display the data in a div. I would like to use the same code on different pages so the data returned will be slightly different for each page. E.g.
[["screen_id","1"],["name","screen-1"]]

This is hard to explain but here's my predicament. I have 2 drop down menus in a form for "Main Category" and "Restaurant Type". My boss wants it so when Restaurant is chosen from the first drop down, the 2nd drop down appears, which is what this code below is already doing.
The problem is if you submit the form, then decide to go back and change your Restaurant type, the drop down for Restaurant Type is missing. You can get it to come back by switching to another main category, then switching back to Restaurant. Code:

I am developing an iPhone version of a web app for a company I work with. The iPhone version is saved to the user's Home Screen as a pseudo-app (for lack of a better term). SSB might be more accurate. Everything in the site takes place in one window. Because there are navigation arrows within the web app itself, I don't want the browser's Back and Forward buttons to ever be enabled, because it can confuse the user. Hence, page navigation within the app is always done via location.replace().
My challenge was with the Login page. With a standard HTML form, the browser (SSB) navigates to the "action=" page specified by the form. So then you have a Back button. To work around this, I have created a "fake form" which simply writes the user's password to a cookie with a 5-second lifespan and then does a location.replace() to a Perl script that grabs and evaluates the cookie, immediately deleting it, and then writes the page to the browser. This works like a charm.
Question #1: is it an abomination to store the password in a cookie, even for a few seconds?
Question #2: At present I'm not encrypting it. Is there an effective client-side JS solution for encryption? Or, if it's client-side, wouldn't anyone be able to read the script and see how it was done?

I am wondering how Back, Forward browser button works for iframes. Does it bring back/forward iframe or top window? I remember I had before a problem because I wanted to bring back iframe and not top window as it did. But today I tested my Facebook app and was surprised to see it works as I need which means it brings back/forward iframe window and not top. Is it possible that Facebook has some javascript code which does that or is this normall behaviour?

I'm trying to communicate between a parent document that is controlled
through pure Javascript with an embedded IFrame containing an ASP.NET
form. I can quite easily pass data into hidden fields in the IFrame and
submit the form to pass data to the ASP.NET application.
Now the tricky part! (at least for me, probably not for everyone
else!), how can I set a field in the ASP.NET page (using ASP.NET during
a postback), which I can get the value of within the parent Javascript
controlled page?

I am trying to do a simple ajax request using get(). All I'm doing is sending and ID to a processing page that will delete a record from the database. If the process is successful I am outputting "success" on the processing page, if not "failure". The problem is when I try to check for the "success" string in the get() success function, it never picks it up as being "success". Here is the code I'm using:
$.get('/groups/deleteTopic.cfm?id=' + id, function(data) {
if(data === 'success') {
$("#topic" + id).fadeOut('slow');
[Code]...
I validated that the processing page is indeed outputting "success" to the screen by going directly to the page and passing a valid ID in the URL. Also if I alert(data), it alerts "success".

The following will submit the form data to popup by clicking the submit button. I want it will submit the form automatically to the popup, there is no submit button in this page. Basically this page should not show up.
<script type="text/javascript">
function submitmyform(f) {
f.target = 'foo'
window.open('',f.target,'menubar=no,scrollbars=no, width=800,height=800');
f.submit();
return false;
}
</script>
<form name="myform" action="popup.asp" target="_blank" method="post"
onsubmit="return submitmyform(this);">
<input type="hidden" name="item" value="item"/>
<input type="submit" value="submit to popup"/>
</form>

For the first time in a long time, I've encountered a project with a single image that has many regions.Each region is a polygon, and will bind to a unique rollover event. That rollover event will pull back data for each region.I've thought of using a hidden image in a canvas with a black background, and a different color foreground for each region. Then, mapping the color the proper region data on the backend.I've thought of passing a huge Javascript object with keys that relate to a position in the image, and values that define the region data.Initially, I dismissed the idea of a good, old-fashioned image map, in an attempt to find something sleeker and sexier. But perhaps this is the best solution?

I have a graphic with a rollover for site navigation on each page. I
put the page to go back to in the rollover javascript.
My question is, is it possible to put in some code that will refer the
visitor back to whatever page they came from rather than one I
specify?
The rollover is combined with a tooltip script to make matters fun
(below). However, I'm quite happy to lose the tooltip to have the link
perform as a back button.
<a href="../index.asp"
onmouseover="document.images['link1'].src=img2.src;
showtip(this,event,'Back to home page');"
onmouseout="document.images['link1'].src=img1.src; hidetip()";><img
src="bhome.gif" name="link1" border=0></a>

how do i make the page go all the way to the top after you press the back button?
for example, you would go to page 1 and you scroll mid-way, then you press a link to page 2. then you press the back button on page 2 and takes you back to page 1 but it brings you back to the section where you scrolled mid-way.
is there any way to make it so it will automatically bring you to the top of the page. ive seen it on other sites.

after hitting 'back' button I'm taken to spot on page where I was, but I'm being asked to do the opposite -- take user to the top of the page, after hitting 'back' button... when I look up this issue, most people complain of the opposite - that the browser takes them to to top of the page after hitting 'back' button...;-) [URL] is there a way with JavaScript to force page to go to the top of the page when you navigate to a back via 'back' button?

The site that I'm currently working on is related to a computer game, and I'm creating an interface similar to the game using js for rollovers and imagery changes.
However, one thing that web browsers have that the game doesn't is a "Back" button. I don't want to disable it--I hate when sites do that--but I want to makes sure that button changes that happen going forward also happen going backward.
That said:
1: Is there any way to force a function to run when the back button is pressed? And if not...
2: Does the body onLoad event work when the page is returned to using the back button?

Is there a way in IE to trap when the back button is pressed to do things like prompt the user to save or do some function other than going back?
