Separation Between View And State (The Back Button)
Jul 13, 2006
Let's say you have a "Buy" botton that posts a form to a script that
inserts or increments the quantity of a record in a shopping cart
table. So you click "Buy" and then "Checkout". Now if you hit the Back
button it asks the user if they would like to repost the form. If they
click "Ok" the db script runs again and now they have two items in
the cart.
It seems to me this is a fundamental model view controller kind of
problem. There's no seperation between the view and the controller. Can
someone recommend a generic method for providing that seperation? I could
have the script emit a Location header but that's a strange hack. What
is the definitive method for solving this probably very common issue?

In Mac Safari 4.04 & Firefox 3.6, I am seeing page state being persisted on back button to page. I couldn't reproduce on jquery 1.3.2.
Here's a simple example:
<html>
<body>
<script type="text/javascript" src="jquery-1.4.js"></script>
<a href='#content1'>tab 1</a> <a href='#content2'>tab 2</a>
[Code]....
1. Click on one of the anchors.
2. Goto another page
3. Click the browser back button
Result: One of the sections is still hidden. Is anyone else seeing this? How is jquery doing this?

I have a page where a user can progressively download more thumbnail images. New thumbnails are loaded using '$.get' followed by an 'append' to the main thumbnail container. If a user clicks on a thumbnail then they link to another page to see the full size image. If the user then presses the back button, the page of thumbnails has returned to its initial state. I was hoping that all the additionally downloaded thumbnails would remain in memory! Is there a way around this? Keeping track of any additional thumbnails that have been downloaded when navigating the to the full size image page and then re-loading them when the user returns to the thumbnails page is not really an option as I don't want the user having to wait for this. This is what facebook appears to do after one has loaded lots of additional items on their news feed - if one links to another page and hits the back button, my suspicion is that all the items are re-loaded - they're not just re-displayed from memory.

I have a scripts which filters a list of data based on a users selection from dropdowns in a form. The script updates a counter while the user is making the selections and also colates a url string which I then use to query a php db when the user clicks view results.
I also have a reset button in the form so the user can quickly go back to the start. When this is clicked it does reset all the dropdowns and inputs to their defualt values but it doesn't reset my js functions back to their initial states.
Can anyone tell me how I can do this? Is there a js reset function I can use?

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'm trying to avoid using frames. I have a page that is very long, but I want the user to be able to hit the submit button at any time. If it could follow them as they scroll that would be perfect.

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 used the code from the following article...[URL]
$(function() {
$('img[data-hover]').hover(function() {
$(this).attr('tmp', $(this).attr('src')).attr('src', $(this).attr('data-hover')).attr('data-hover',
[code]...
why does the rolled over image's src return to the original value when the user rolls back off it?

To say I'm new to JavaScript is a bit of an understatement so bear with me. I have a site set up with a variety of layers of toggles. When you enter the site all of the items are collapsed and you click the headings to expand. Each of the toggle-able items have ids. It works great for users who start at the homepage.
However, when I send people to any of the inner topics, all they see is the initial collapsed state of the site. I want to be able to provide a URL that will set the toggle to open, and show all of the content for that section on entry.
Here is my code and js, can anyone point me in the right direction?

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?

I have used thickbox js library to display 'popup contact cards' on a private website. which requires the user to login, I chose this as it's far better than using real popup widows, or full windows do display the small amount of info (name, position, and phone number).
However the client has had trouble with some users clicking the browser back button to exit the 'thickbox' screen instead of the 'close' text in the thickbox header bar (or using the esc key as you can in the latest version of Thickbox), clicking the back button sometimes leads to the user being logged out returning them to the 'please login' page.
