JavaScript - Iframes And Parent Url Updation With Back Button History
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. Similar TutorialsI've been working on a site where the content is displayed in an iframe. The iframe content is on a different domain than the iframe itself. I've already got around the cross-domain problems by creating a file on the parent domain that the iframe content references via another iframe. (which uses parent.parent to skip the permissions issue) That was all fine and pressing back and forward in the browser navigated back and forward in the iframe (at least in FF, not 100% sure about other browsers) Then the client wasn't happy that the url in the browser didn't change and pages couldn't be bookmarked. So I created a solution where the parent.parent.location.href was changed to be domain.com/#/path/to/iframecontent.php so that pages could be bookmarked, that works fine but now back and forward don't work, or more specifically the url changes correctly but the iframe content doesn't go back. I need an html page that when visited automatically redirects the browser to return to the previous page it was on. here is the current code I have: Code: <head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Untitled Document</title>
<script type="text/javascript">
function load()
{
history.go(-1)
alert("");
}
</script>
</head>
<body onload="load()">
<input type="button" value="Back" onclick="goBack()" />
</body>
</html>
this works in firefox but in IE you have to press ok in the alert box before it returns. I admit I am a javascript novice. Any suggestions I am not sure if this has been posted before but I need help with this. When a user clicks on the back button I need them to be directed to the previous page and still have their original selections and not the defaults. Here is the rest of code on the back button. At the moment this is not working. <input id=STDBUTSHORT type="button" value="Back" onClick="history.back();">') Thanks in advance. Hi I am using back button with javascript:history.back(); on it but the page I want to go back have anchor link smth like: http://example.com/index.php#anchor_link How do I go back ? I've tried javascript.history.go(-1); a I have an Iframe in my webpage wher I have the focus. I now want to give the focus back to the parent document, so i've used top.focus() in my code. Works fine in almost every browser but not inIE7. Any hints? I have a popup window which display a list of values in a tabular form. I have no problem to do the popup or display the table. The table has two columns; one is the "code" and the other is the "description". When a row is highlighted and the "SELECT" button in the popup window is clicked, I am supposed to pass the "code" of the highlighted row back to an input textfield in the parent window. And I am struggling with it. Would anybody kindly help? Hello guys. I've been struggling on how to make this work. I have a problem in Javascript when it comes to passing of value in a input type field. page1.html Code: <html>

I want the value of Code: <input maxLength=3 size=1 value=0 name=C disabled> , this is from hw_calculator.html, to be passed on the Code: <input type="text" name="weight" value=""> on page1.html. How can I do this? Huge thanks. 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 have the following code which i am trying to insert a 'back button' into to go back to the previous page. i can only seem to get the button to appear either at the very top or very bottom of the page, does anyone know how i can specify the location? this script is generated from easypano tourweaver - Code: <html>

here is the button code - Code: <span onclick="javascript:history.back()" style="text-decoration:underline; color:blue; cursor:hand">Back</span> 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. 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>
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.. 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? 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, 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> 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!!

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 );

Hi 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. |
