Why Can't I Access Child Frame Elements With The Direct Form?
Jul 20, 2005
I have a document that contains a child frame with name/id = "help_frame".
From Javascript in the top level document I can access the child frame's
elements using:
var elem = document.frames.help_frame.document.getElementById ("chkSynonym");
but if I try:
var elem = document.frames.help_frame.document.chkSynonym;
the result is 'undefined'. What is wrong with my syntax?
I have a simple html document I have been using for some time on my (i.e.) abc.com domain that uses cookies. I recently purchased a new domain name and set up a service to redirect my new domain (i.e.) xyz.com to a sub-directory of the abc.com domain. In other words, when someone goes to URL xyz.com, they really end up in abc.com/xyz directory but the MSIE browser says they are xyz.com.
The problem is that cookies quit working in this setup when I copied the same HTML document in the /xyz subdirectory that xyz.com now accesses. I can't set or get a cookie any longer by calling the document.cookie function from JS any longer. The call does not fail but the data is always blank. I even tried setting the cookie and from the next line of code reading it back immediately and it still would not save the cookie.
Anyone know how to fix this?
I checked the value of location.host, .hostname .pathname, document.domain and they all indicate I am really at abc.com even though the address in my IE browser says I am at xyz.com.
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.
I have a parent document that has a frameset with two frames in it. The first frame is a "header" that runs across the top of the site, and never changes. The second frame contains the "content" of the site. Essentially, I am trying to figure out how to prevent the header appearing above external sites when the user clicks an external link in the "content" frame.
Every time the content frame changes to a new URL, I would like the check that URL and determine if the content frame is changing to an external URL (i.e. different domain in URL) or to an internal link (same domain in URL). If the content is changing to an external link, I want to break out of the frame and just load that external link in the top most document.
I would like all of my javascript to be in the parent document, not spread throughout the individual pages of the site. I was trying to approach this by setting the onunload event handler of the content frame, but I am left with a couple of specific questions: 1. In handling an unload event, can you determine the next URL that the document is loading? Code:
I've put together what I think is an illustration of my problem at [URL] Quite simply, I need to be able to access the elements of the form without referring to them by ID as the whole form is intended to be cloned. I intended to do this using parentNode and childNodes[] together with the 'this' keyword. My understanding of 'this' in this context is that it should refer to the HTML element calling the function, i.e. one of the radio button inputs. However this gives the error "Error: this.parentNode is undefined"
Is there a way to access a form element that was created using AJAX?I've had no luck when using 'document.getElementById( elementID )' as the element doesn't appear to be recognised.
i want already select .postlike in $(this) now i want to select the tagh1 who is in .commentboxelements.i want to change the h1's inside text 1 to 2 so i write the code
$(this).closest('.posts').children('.commentboxelements center h1').html('1');
i try this but it's not worked anyway how i can do this.
This pops up a new window with every call. In the child window I call a parent function onbeforeunload, appClose() :
function appClose(){
if (window.opener && !window.opener.closed){ window.opener.CloseChild(getQueryString("application")); }}
This is in my frameset tag of the child code :
<frameset ... onbeforeUnload='appClose()'>
The window.opener.CloseChild() function is called perfectly when I have one child window open, but as soon as I create another child window both of the open child windows don't ever call it. They do both go into the onbeforeunload appClose() function, but do not call the window.opener.CloseChild() function inside of this routine.
Anyone have any ideas why when I have two child windows open I can't access the window.opener functions?
I have tried taking each new window out of the array and used the following code in CloseChild() :
How do I force a window, pened alone, to be displayed in its frame set?
tried this:
if (parent.location.href == self.location.href) { window.location.href = '../' }
the problem is that the original page is replaced by the main.htm page (the default page for the 'main' frame)., because the open event of the menu page calls for the main.htm to be loaded. Is there a way that I could pass a page name as an argument to the index page at all? Something like window.location.href='index.html?Loc=IT_Study___In formation.htm'
I'm trying to create an HTML page that contains two frames. The bottom frame should simply be some website, but the top frame needs to have a close link to kill the window. I tried calling 'document.window.close()' from the child frame, but without success. I then tried putting the 'close()' call in the parent page and calling it from the child, but still without success. Code:
I know how to access *all* paragraphs in another frame and (eg) change their text content.I do this via the following code (code A)$('p' , window.parent.log.document).text('test')(log is the name of the frame that contains the paragraphs)But I cannot access a *particular* paragraph (eg the 2nd paragraph) - if there were no frames in the document I would do this via$('p').eq(1) but I cannot get this to work using any variation (and I feel as if I've tried them all!) of code A.
I have a frameset page that creates several subframes. Does anyone know how to inject the script tag or some js code into the child window before loading of the child frame begins? The reason is to make the pages back-compatible with another system without changing a lot of code. If I can inject the script before the page loads, then it will handle the compatibility issues.
I've successfully injected the code into the child frames by using: frames.childName.window.eval.call(frames.child_name.window, myCode);
And the functions are available to the child frame after it loads, but the code needs to be available to the child frame before/while it is loading.
Is it possible to direct link to a JavaScript element i want my people to be able to get to a form but in order to get to the form on this other site they have to press a JavaScript button. Which shows a a javascript form. I want to be able to directly bring them to that form in one step. Is there a way i can do this from my site to the other site...( i do not own the other site) if that helps
Is this possible? Also, while I am dreaming, could a web developer extract the frame necessary for the form /review box) and show just that, without the surrounding content? It would be totally awesome if I could extract a live review box and show it an isolated frame.
I am encountering a problem where I have a window and there are three frames, one in the left, right and in the bottom. The bottom most frame has common submit buttons. There are several tabs in left frame. Each one loads a different form on the right frame. After fetching the contents of the form from user, I am validating the text fields in the form using onChange() event handler. After entering the text value in the textbox, if I press Submit directly, the "Submit" as well as the validation routine happens concurrently. Only at the end of validation, the field is marked as dirty. Now, if field is not marked dirty, the Submit function will close the window without actually submitting as nothing was changed. So when an invalid value is entered and the Submit is pressed directly, an alert pops up temporarily but the close() call from the parent frame immediately closes the alert window before user can respond. This problem does not occur in IE as in IE, unless the alert window is responded, the close() call cannot close the alert window. Code:
A pgn-file is a plain text file. It's used for chessgames.I want Firefox 1.5.0.12 on Win XP SP2 to show the pgn-file in a frame when I click on the link.That's the first problem: Since I installed some years ago some chessprogram Firefox always asks what to do with a .pgn-file (Download dialog).I know I can change this behaviour either in config:about or in some configuration file for mime types.But how to do that??? (There are extensions for that, but only for Firefox 2 and higher. ): And I would prefer to change it via the about:config-file or in the mime-configuration file, some .rdf-file I think.Then I want to access the plain text in that frame with javascript. How could I do that?(If you need a pgn-file to test, just take any text-file and rename the ending to .pgn.)
I have a web form (yeah) that I would like to have jquery direct the post and the form values to one of two php pages depending on the choice selected.
Ideal flow:
If a person selects radio button "email" and clicks submitsend form values to page1
-Generate and send email and report success
-User never actually sees page1
If a person selects radio button"view" and clicks submit send form values to page2.
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 have the xml loaded and I can count three events xmlDoc.getElementbyTagName('event').length What I want to do is get the child elements of the event, but I cant figure it out. xmlDoc.getElementbyTagName('event')[0].childNodes[0] shouldn't this be the <image> tag of the first event? I want to pass the event as a variable and then access the child var thisEvent = xmlDoc.getElementbyTagName('event')[counter]
The problem is that I'm creating child elements based on an xml document served from a php script. However everytime it is served I'm just appending all the elements to the end of the child list creating copies. So I decided to just remove all the children each time.. But this doesn't seem to be working.
