I have set of frames... one contains a menu and the other a status frame. I am calling a function from the menu which sets the variables however I need some help passing those variables to the status frame. How would I go about doing such a thing?
This is called from the menu in frame 1 but doesn't work:
Code:
function jumpsec(cat, prod) {
parent.statusbar.category=cat;
parent.statusbar.product=prod;
}
// then my status frame bar has:
document.write(parent.statusbar.category);
document.write(parent.statusbar.product);
The 2 variables are blank on statusbar onload but get populated with each click.
I have need to communicate between two iframes of the same domain, which live inside a parent page on a different domain that I have no control over. This is a Facebook app and the basic layout is this
apps.facebook.com/myapp L iframe1 (src='mysite.com/foo') L iframe2 (src='mysite.com/bar')
I need frame1 to talk to frame2, but in Opera I can't access window.parent. frames['frame2'] to do the usual cross-domain methods (updating location.hash for example) Is there an alternate way to accomplish this in Opera?
I'm doing an intranet with a media part. So im must be able to upload files on a ftp server AND have a record of informations about this file and meta date in a MySQL database, shown in a php page.
So the first thing i was doing was:
1/ * A HTML Form, with a <input type="file"> which was uploading the file to the web server. And then, in the next action-php-page, using ftp functions from php to upload to the ftp server. But this make upload the file 2 times, which slow, and the user can't do anythig except waiting in front of a blanck loading page.
=> no way
(BTW, the site admin refuse that the ftp server and the web server to be the same computer)
So i tried something else:
2/ * A HTML form, the user enter meta data about the media, click next, and then, a php page which loads a java applet an pass informations to it (by param tags). The applet have a browse button, and a go button, which start the transfert (JDK 1.4.1) trough the URLConnection. The file is uploaded once, and there is a progress bar, which is wonderful.
But now, i need the src_file information wich is the java applet. So i have two options:
A/ I make a post to the webserver from the applet. But i'm using session identification (needed for tracing users actions) and i'm gonna use SSL in less than one month, so i think it would be complicated.
B/ I export the information from the java applet to javascript, and then to HTML hidden field, so that the user can submit the full-hidden-filled form. But i can't make LiveConnect works.
i'm under Mac OS X 10.2 (jaguar) so i need to make work LiveConnect on both Safari 1.0 (v85.6), mozilla 1.5, and Mac OS IE (5.2).
I'm having a hell of a job getting this to work in Safari: the only thing I can think of is that one can't use reload() across to another frame for security reasons. Does anyone have a concrete answer or solution for this? I'm trying to do this:
Is it possible to run an HTML file from "localhost" and bypass the various security checks in place for cross-frame scripting? For example, on a 2-frame page loaded locally:
a) frame 1 includes a form that accepts the name of a web site (example: www.foo.com), which a script or perhaps a "target" attribute then loads into frame 2 b) frame 1 waits for frame 2 to load, then reads (for example) top.frame2.document.images.length and displays the total in frame 1
I realize that "localhost" is not going to match the domain appearing in frame 2, but as I myself am running the script, logically, where is the harm?
I haven't done much testing with this yet, but am planning an application around this concept and am hoping I can make it work. Any pointers?
I'm trying to dynamically set the height of my Iframe. my https: main page is calling another https in an Iframe. But i get an access denied error from my javascript trying to call the parent document.
Main https page <IFRAME APPLICATION="yes" style="width:100%;" id="iframename" frameborder="no" scrolling="no" SRC="https://www.otherdomain.com">
otherdomain.com html ------------------------------------------------ <script> function bodyheight() { x = document.body.scrollHeight parent.document.all.iframename.style.height = x } </script>
I am using this code to refresh the browser after a iframe has finished loading. Does anyone know a cross-browser one that will work on all browsers. I have tested it on firefox and internet explorer, it seems to only work on firefox.
i need a DHTML drop down menu sample with framesets used or the cross-frame..i dont have any dropdown menu creator because they are just a trial verion..
I'm considering in teaching myself some javascript, but before I take the time to read up and experiment, I had a few questions.
Is javascript XHTML 1.0 STRICT Valid? Is javascript valid for any version of XHTML? Is javascript easily cross browser compatiable, or will this take a long time to work around?
I'm working on a little frames based web market research tool (not for public consumption) which allows us select various supplier websites via a link in a header frame, to be loaded in a main frame, from which we may drag data to be dropped into a form in a third form_frame which then submits to our database. All in all, this works nicely until we come to one of the supplier sites which has implemented a frame-killer script.
Now, I know it would be bad form (probably illiegal even) to force a site into the frames of another site for public consumption but I don't think that is an issue here so I ask you all ... Is it possible to disable JavaScript (on the fly) for a given frame only?
I have two frames. "Top" contains a local file on my server with the aforementioned javascript. "Bottom" is a remote website on a server I do not control. I want to use javascript in "Top" to determine what the current url is in the "bottom" frame...
I have an outer page and an inner iframe. The outer page calculates some javascript, and wants the inner frame to run it. The inner frame should hit a page on the same (private) web server, so this is not a cross-site scripting attack. But I would prefer not to taint the target page with any extra logic to do this. (I will if I must.)
Note that both the outer and inner page have a span with the same ID.
This question will resemble a JavaScript FAQ - how to evaluate Javascript on the fly, or how to reload a JS file. The answers on the web generally do not transport the JS across a frame boundary, so they don't address the bug I encountered, and I can't tell if prototype.js or IE is at fault.
The outer page calls Ajax goodies that generate some JS looking like this:
Element.update("update_me", "here I B");
The page sends that, as a string, into this JS (in application.js):
function update_grinder(sauce) { var grinder = $('grinder');
if (grinder) { var doc = grinder.contentDocument; if (!doc) doc = grinder.document; if (doc) { evaluate(doc, sauce); return; } } document.write("your browser sucks"); }
So that contains enough logic to find the iframe's document, and it works for Firefox, IE, Konqueror, and Opera. The code calls evaluate() with the document where we need the evaluation context, and the string with our source.
Here's evaluate():
function evaluate(doc, sauce) { var s = doc.createElement('script'); //s.defer = true; // <-- no effect s.text = sauce; var body = doc.getElementsByTagName('body').item(0);
if (body) { body.appendChild(s); return; } body = doc.body; if (body) { body.appendChild(s); return; } }
That creates a <scriptblock, sticks our string in as its contents, and pushes the block to the end of our <bodytag. Now here's the bug:
Firefox updates the inner <span id='update_me'>, and IE updates the outer one.
If I remove the outer <span id='update_me'>, then IE simply can't find it and throws an error. Even though it evaluates a script block clearly in the context of the inner iframe.
I have tried calling the script from setTimeout, and from a button's onclick handler.
Is there some script.aculo.us way to fix (yet another) bug in IE? Or is this a bug in prototype.js?
Is there any way to resize an iframe dynamically to the height of its content that works cross browser and works when the iframe content is on another domain than the main page (I have access to both pages, so code can be put in either) Also, it must resize when links in the iframe are clicked (ie when a new page within the iframe is loaded)
I need to fix the communication between the JS located in this page and the PHP form script. When the form is submitted I want the page to automatically update which is already present in the script, thanking the user for the submission. Since the PHP script was changed that communication is broken and I hope to get it communicating once again.
How can I inform a Javascipt, that must submit my Applet's data, that this same Applet has produced the data in question? Or in other words, is there any way to call a JavaScript junction within the Applet? Is it the best way? What do you suggest?
I am very new to web development. I would like my website to have an application which allows a user to draw images which can be displayed on other users screens in real time.
An example of this is isketch.net Also on this site i would like users to be able to create accounts and join 'rooms' where they can communicate in real time (as opposed a forum message board). I am looking for something similar to isketch.net
Could somebody please tell me the type of development and programming needed. I have been quoted 1000 a month to build these capabilities but have no idea what is involved. (also may require facebook style real-time updating)
I am new to Javascript and am trying out window communication with a popup.In the main window it opens up a popup window with a button click. The popup window is trying to grab text from the main window and put it in it's (the popup's) window. I guess it needs a test to see if the window is ready??Here's the code:
I have a domain: example.com; which is the parent.And a subdomain: api.example.com; which page 'receiver.html' is being loaded in an iframe, child of parent. Both pages set document.domain = example.com.
I'm trying to adapt this code:[url] but Idon't want to load jQuery from the <iframe> again but I need to have the method $.ajax() working from the <iframe> otherwise it would be a cross-domain request and the browser would abort it. I tried ingenuously to set via $('iframe')[0].contentWindow.$.ajax = $.ajax() and I just got a shortcut to the parent page jQuery method. I also tried to "clone" it using $.expand (true...) but the method doesn't work for me; probably because of the complexity of the objected I'm trying to clone. So is there a way for me to use jQuery to have only a $.ajax() method in the <iframe> ? I've thought even about creating a XHR in the child-iframe and then use that in the $.ajaxSetup ({xhr: THATNEWXHR}) but I couldn't do it. I mean, I want to use the XHR factory from jQuery (which has fallbacks for IE, etc) but it has to be created from the iframe-child.
Maybe there is other way to make the AJAX call come from the child-iframe.
If you're wondering "why don't you load jQuery from <script> in the child-iframe", there is a reason... As I'm using jQuery plugins + my own custom javascripts + other independent scripts I created a compiler which minifies each file and bundle them in one. The advantage of this is the reduction of HTTP requests. So "why don't you load that bundle inside the child-iframe?", because it's ugly and Twitter doesn't... Yeah, I like to take Twitter as a reference and I think if they were able to make it so can I;
I got to work in most browsers except IE and Operaby doing it with pure javascript.
I'm "attaching" the code for you guys to test. If you open it with Chrome, Safari or Firefox you will receive 2 alerts one with the return of $.get() and another with the return of a request made via XMLHttpsRequest object. Otherwise (if you open it with IE or Opera) you'll get 'undefined' in the first alert but the real return in the second.
Im trying to make a back button that reloads the previous page the user was at. The back button will be on a small top frame and the page that needs to be controlled will be in the main frame.
The top frame is just a navigation system, and all pages will be loaded in the main frame. Im trying to use this Code:
I'm trying to find a way to have a script communicate with a server without having to load a new page. The idea is to have the server act as a simple wrapper for a database, letting the client do that icky UI stuff.
I tried the obvious, putting a frame somewhere it doesn't insult the eye, changing its location, then accessing the new content via DOM. What I get from IE (6) for my pains is just a rude "permission denied". This even though I entered "localhost" as a trusted site in IE's security setting. What's amiss?
