JavaScript - Best Solution For Browser Back Button On A Page Using Iframe Content?
It's a well documented issue-
when you have a page that contains an iframe, and then navigate inside the iframe, hitting the browsers back button will only affect the contents of the iframe and not the entire page. I've been searching all over for solutions and cant find one that works for my current implementation. Anyone have any suggestions? Here is my code: js Code: function ShowPage(frame)
{
frames[0].location = frame+'.html'
frame.contentWindow.location.replace(newUrl);
}
Buttons that change the contents of the iframe Code: <div id="thumb1"><a onmouseover="ShowPage('frame1')"onclick="ShowPage('frame1')" rel="nofollow" target="mainbox"></a></div>
<div id="thumb2"><a onmouseover="ShowPage('frame2')"onclick="ShowPage('frame2')" rel="nofollow" target="mainbox"></a></div>
<div id="thumb3"><a onmouseover="ShowPage('frame3')"onclick="ShowPage('frame3')" rel="nofollow" target="mainbox"></a></div>
and then the iframe itself Code: <iframe src="frame1.html" type="text/html" style="border-width:0; border-style:hidden;" transparency="true" name="mainbox" frameborder="0" scrolling="no" width="700" height="807"> </iframe> Similar TutorialsHi All, I am using a loop slider to scroll 4 pages. When I am on any page and click through the product on that. I go to the product but when I click the back button, it goes to the start of the slider rather then the page where I left it. How to go back in loop slider from a back button to the page where we left the scroller. Instead of going to the start of the scroller. It is annoying to go back again to start of the page and scroll all pages. Any help, Highly appreciated. Regards, Meenakshi. Hi I am trying to trigger an event once the user clicks the browsers back/forward buttons, I have built a system just like facebook where if the user has javascript turned on they get the full feature of the site which includes fast switching for example if someone goes to this page "example.com/index.php" and click a link to contact.php it would change the url to "example.com/index.php#!/contact.php" but what I need to know is if there is any way to change the pages content when the user goes back and forth through the fast switch pages? something like "history.back !== -1" or something like that. If anyone can help please reply, thank you. Hello, I need some script to force the browser to reload/refresh when a page is reached from the back button. EG You're on page A -> You click a link onto page B -> You Press Browser back to go onto Page A, it has old content that requires a reload. Now, my page is currently php so I won't bother with my code here as I am looking for any solution (I have also posted in php forum). Any JS solution that will trigger a reload on browser back is appreciated. I have tried a few ideas, most work in Chrome, IE always works, Firefox 4 and Opera 11 wont reload, simply fetching from cache I believe. Thanks. I am trying to write script that allows a user to select a new page using a select menu. But if a user changes mind and clicks Back button. i want a use to see again "Select a New Page" as a first option in the select menu. instead i see the page that was chosen before. in firefox, even when i click Refresh button, the select menu does not go back to its initial format. I tried to use the principle that each time window is loaded, the selected Index would be 0. it is not working. Could anyone give me a hint on how to fix this problem? my script is below. <html> <head> <title>Jump Menu 2</title> <script type="text/javascript"> function new_page() { var selectmenu=document.getElementById("states_form").states_select; selectmenu.onchange=function new_state() { var i=selectmenu.selectedIndex; var state=selectmenu.options[i].value; var new_page="http://www.50states.com/"+state+".htm"; location.href=new_page; window.onload=function select_reload() { i=0; } } } window.onload=new_page; </script> </head> <body> <form id="states_form"> <select name="states_select"> <option value="0"> -- Select a New State--</option> <option value="nebraska"> Nebraska</option> <option value="texas"> Texas</option> <option value="florida">Florida </option> <option value="oregon"> Oregon</option> <option value="wisconsi"> Wisconsin</option> </select> </form> </body> </html> The project I am working on involves a flash piece that communicates with a iframe. Currently the flash piece just calls on javascript functions. I want the buttons in the flash piece to be able to change the src of the iframe. PHP Code: <script type="text/javascript"> document.getElementById('video').setAttribute('src',address2); function closeVideo() { document.getElementById('video').style.height='0px'; return false; document.getElementById('video').setAttribute('src', address2); } function openVideo() { document.getElementById('video').style.height='391px'; return false; document.getElementById('video').setAttribute('src', address); } </script> So the way the code works now is when the page loads it sets the iframe with the id of 'video' to the variable address2 which it pulls from an XML file. In the flash piece when a button is hit, it calls openVideo() which "opens" the iframe and I want it to change the contents to address. This does not work though. It opens the frame but will not change the src. I've tried a bunch of different things now such as make the flash target the iframe using navigateToURL(request1, 'video'); but in Firefox and IE is opens it stills as if I had _blank in there. It does strangely work in Safari. Any ideas how to get this to work? I'm new to javascript so it could be something basic I'm overlooking Ok, I am aware this will sound like a plug for my script, but please bare with me. I created a bookmarklet script to help me audit extremely large style sheets. Basically while on a site that you would like to audit, you click the bookmarklet and the document's body contents gets remove and replaced with an iframe that points to the current sites home page. From here you can choose what style sheet (the script finds) to begin reporting over. The more pages you browse (through the iframe) the more accurate the report gets. My problem however, is if the person is on the site's home page when first running the script, the iframe never loads up. I think it has to do with the fact that you are on the home page, and then the iframe tries to point to the home page as well and fails for some reason. Is there any solution that comes to mind for anyone out there? You can test it by bookmarking this bookmarklet and running it on any site's home page where style sheets can be found: Get The Bookmarklet on this page Again, it works great if you don't start the script from a sites home page. Hi! I have a mysql database with a bunch of quotations in it. I created a blog at http://aro2220.blogspot.com At the top of the blog is an iframe window that directs to http://aro2220.com/blog On that page it uses php to pull out a random quote from the database. The iframe window displays that quote onto the blog. It works great except that the height is not automatically resizing. Is there a way I can use javascript to do this instead? Here is some pseudo-code of what I'd like to be able to do: (p.s. I do not know javascript or much of anything so I am looking for people to tell me how to ACTUALLY do this) Quote: var stringvariable = http://aro2220.com/blog/index.html; int stringlength = stringlength(stringvariable); int autosize = 200 + stringlength * 5; <iframe width="100%" frameborder="0" src="http://aro2220.com/blog" height=$autosize scrolling="no"></iframe> Obviously these are not real functions or proper syntax but hopefully it will paint a clear picture on what I am trying to do. this function seems to be working fine in all browser but of course. I'm still a noob at JavaScript and well things like this just doesn't make sense. when I go to alert this function in IE I get undefined. But other browser gives me a value. What am I doing wrong with this function? Code: function ext() {
var img = document.getElementById('photoSmall');
img = img.src;
if (typeof img == 'string' && img != 'undefined') {
var typeis = img.substr(-4);
if (typeis == '.png' || '.jpg' || '.gif') {
return typeis;
}
}
}

here is the button code - Code: <span onclick="javascript:history.back()" style="text-decoration:underline; color:blue; cursor:hand">Back</span> I want to place a Logo/ad in front of content, there are ways to do it but the problem with them is that they use JS show/hide method. What happens is that the content doesn't load while user is watching the logo/ad, which results as double waiting for the user first for the logo/ad and then the actual flash content loading. So I was thinking if there is a way that a logo/ad could be displayed and at the same time flash content continues to load at the back end. *I didn't ask for a loader that continues to appear until at the back end flash content is done loading, because I found only one script that was able to do so using Jquery but it was designed to work with fixed pixels while my flash content is based on %ages* Live Demo: http://bloghutsbeta.blogspot.com/201...ent-issue.html Note: Sorry for providing blogspot link but JsFiddle is not an option for a person living in Afghanistan with 5KBps but still if you feel that I am missing something please let me know I will edit it and try my best to provide as relevant question as possible ^^ Relevant Markup: Button for lightbox or Modal Window Code: <a class="poplight" href="#?w=100%" rel="popup_name"><img alt="play game" class="happybutton" onmouseout="this.style.opacity=0.8;this.filters.alpha.opacity=80" onmouseover="this.style.opacity=1;this.filters.alpha.opacity=100" src="http://farm5.static.flickr.com/4084/4998558471_27e3985c16_m.jpg" style="opacity: 0.8;" /></a> Code: <div class="popup_block" id="popup_name">

I have an HTML page that is making use of JQUERY and many other JQUERY plugins. Inside this HTML page there are 2 different types of iFrames that display PHP forms. One is a normal iFrame: Code: <iframe height="740" allowTransparency="true" frameborder="0" scrolling="auto" style="width:100%;border:none;overflow-x:hidden" src="https://www.website.com/machform/embed.php?id=9" title="Contact Us"><a href="https://www.website.com/machform/view.php?id=9" title="Contact Us">Contact Us</a></iframe> The other makes use of a JQUERY plugin called Shadowbox: Code: <a href="https://www.website.com/machform/embed.php?id=8" rel="shadowbox;width=1100;height=950;player=iframe" class="button1"><span></span><strong>Click Here</strong></a> Inside these iFrames are PHP forms from a PHP form application called MachForm, which is highly customizable. Here are the questions. Ultimately, I want to accomplish 2 things: 1. I would like to send variable information from the PHP form in the iFrame to my HTML page, to be displayed within javascripts. For example: If someone fills out a PHP form in my iFrame and clicks submit, I want to have a JQUERY popup say, "Thank you, [NAME]". 2. When the user submits the form, the action of clicking the submit button in the PHP form should enable #1, above. There needs to be a way to tell the HTML/Javascript that the submit button on the PHP form in the iFrame has been clicked. I realize this is all fairly vague, especially without the addition of more code. However, I am not even sure if I am posting this in the correct forum, since it incorporates a little of several languages and styles. From this point any direction or idea would be very helpful! I am making a simple puzzle game on Android using Phonegap, that is HTML5, CSS3 and JavaScript. When a user fills an answer on a page, if the answer is correct, it will go to another page. However, once the user goes to the next page, he/she CANNOT return back to the previous page. I do not want the user to return back, else he/she will have to fill the answer again to go to the next page, so it's not good. Thank Sorry if this is the wrong place for this question, but... I'm having an issue with the difference in behavior between the IE and FF back buttons. I'm using jQuery to create collapsable div regions which contain text boxes on a search form. After submit, if the use clicks the back button in FF, the region(s) the user had previously expanded, show as expanded. Also, there search term is still present. In IE, when clicking the back button, all regions are collapsed, in there original loaded state, but the search term is still saved. I put the following code at the top of the page: onload=function(){ alert('Onload!'); } When clicking the back button in FF, nothing happens. For IE, the alert pops up. This tells me that IE reloads the page (but somehow still saves some things, like the search text). My question is, is there a way to keep IE from reloading when the use clicks 'back'? I will be creating my own 'edit' back button for users to get around this, but I also would like to prevent this from confusing users and causing undesired results. Any help would be greatly appreciated. I have a website using this pageslide function http://srobbin.com/blog/jquery-pageslide/ Basically the page you see in the example is acting as a side menu bar and when you click the links on that page, it performs the sliding action and a new page slides into the screen. I'm wondering if there is any way to get the back button to slide it back to the main page, rather than having to click a link to go back? How you handle back button scenario in firefox browser. The problem is when i click browser back button , the javascript on load is not executed and page is rendered from cache. It works in IE.. Hi, I have the following problem: When I use this script it pops up both if a user tries to close the window and also if he presses the back button. Please tell how to show another window or do another action when the back button is pressed? I know it is possible although a lot of people say it's not. Code: <script type="text/javascript" type="text/javascript">
window.onbeforeunload = confirmExit;
function confirmExit()
{
return "blabla";
}
</script>
I am creating a popup for an online store so that when prospective customers put something in their shopping cart and then try to leave the site, they are offered a coupon in a popup. I am using the following code (FYI, uses prototype.js) Code: Event.observe(document.body, 'click', function(event) {
if (Event.element(event).tagName == 'A' || Event.element(event).tagName == 'INPUT' || Event.element(event).tagName == 'IMG') {
staying_in_site = true;
}
});
window.onbeforeunload = popup;
function popup() {
if (staying_in_site) {
return;
}
if (popup_displayed) {
return;
}
popup_displayed = true;
//popup displayed here
}
The popup is not displayed when the user clicks on a link or submits a form (correct behavior) and it is displayed when the user types in a URL or tries to close the browser (also correct behavior). The problem is when the user clicks the back or forward buttons, the popup is displayed which is not the desired behavior. Anyone here have a solution for this? Hello Everbody, I have been at this problem for 10 hours now and am going NUTS!! I am making website to look around an ancient Egyptian Tomb. Feel free to have a look: http://www.campbelltest.co.uk/britishMuseum/online/ I have a flash movie which I have scripted to utilise the browser back button using this script http://www.asual.com/swfaddress/docs/. This works fine until open a lightbox image form within the flash movie using Lokesh Dhakar Light box http://www.lokeshdhakar.com/projects/lightbox2/ and the browsers back button stops working!! The code below is to the JavScript links and the code that lauches the lightbox: Code: <script type="text/javascript" src="js/swfaddress-optimizer.js"></script>

objLink.setAttribute('title','caption');
Lightbox.prototype.start(objLink);
}
</script>

This code is how I have embeded the flash in the page: Code: <script type="text/javascript">
var so = new SWFObject('container04.swf', 'container04', '760', '450', '8', '#ffffff');
so.useExpressInstall('js/expressinstall.swf');
so.addParam('menu', 'false');
//so.addParam('movie','container04');
so.write('flashcontent');
var macmousewheel = new SWFMacMouseWheel( so );
</script>
I have added a text box to movie that shows the back button function exicuting and what its exicuting. I have never done any work with JavaScript before so I am up the creek without a paddle!! The question is on iframes/bookmarkablity and back button functionality. This issue I am facing is how to create iframes with bookmarkable url's without loosing the back button functionality.Lets say all the pages are in the same domain and the child pages inform parent of the child page load for updating the window.location.hash property to modify the current browser address bar. The updation of the url works fine on IE/FF/webkit. But the back button works as expected in IE-8 but the browser back-button does not work in FF/webkit (just the url changes the previous page is not loaded). If we don't update the window.location.hash property the back button works but the window url is not meaningful. Is there a way to get this functionality accross browsers, or is there an easier better way to do it (any other js libs). All pages are served from the same server to get around the permission issue. Gmail and other sites looks like they does something like this. Hello to all and thank you for any help beforehand. I have an issue with the script below, Select the top dropdown and the second gets populated, this is a nice piece of script, the only problem is that when the information is posted and presented on the process page I click page back to the form to rectify some other field but the ajax resets so I have to select Country & City each time even if thease fields are correct. I know that back button as well as bookmark is a problem with ajax but i think there is a solution the only thing is I don't know how to apply it to this script.
