Calling An Anchor In The Parent Page From The Iframe
Mar 20, 2009
i have a page containing an iframe somewhere in the middle of it. the iframe stretche to the end of the page and its height is calculated from its content with javascript.
i want some of the pages i load into the iframe to have a "back to top" link at the bottom. but i can not put the anchor inside my iframe because my iframe doesn't start at the top of the page.
so i put the name linke of the anchor at the top of the parent page which has the iframe inside. but i couldn't find a way to call that anchor from within the iframe.
i'm sure this could be done with a simple code of javascript. how do i get to the parent frame within the iframe?
I have an embedded iframe that needs to call a function from a parent. The parent then automatically submits a form. It is written mostly using php, but since php is serverside, I need javascript to gather information in iframes. Here is what I have:
[Code]...
I am using opera, if that makes a difference. Should probably try it with chrome and IE...
I have a simple javascript function loadNPlay('file'),
parent.loadNPlay('file');
on clicke event it simply plays the file in a player in the parent window. with IE and Mozilla its working fine but with Safari, when called from iframe this function doesn't work(it does work, ie loadNPlay(..) when called in the same window, in safari)
I have tried:parent.loacation.loadNPlay(..) as well, it doesn't work.
I have an webbpage, and in the middle of it there is an iframe to a php site. So i have used this code, so after some seconds the iframe will send the guest to another page. <meta http-equiv="refresh" traget="_top" content="5 url=http://mypage.com"/> But the thing is that i want the WHOLE page to reload, and go to that page after 5 seconds (we can say). With that code, only the iframe are going to another page. Is it possible to make the whole page send the user after some seconds, to another page and not only the iframe?
I'm working on a upload script that uses javascript, and a hidden iframe to upload the files. It all works up until the iframe finishes and needs to send the javascript function call back to the parent page, nothing happens, when it should hide the upload progress bar. I've searched and searched for the answer, along with trying different alternative to window.top.window, such as window.top, parent, and parent.document and so far nothing has worked, I've even tried the onLoad on the iframe with no success.
Parent Page function: function stopUpload(success, ups, file){ var result = ''; var uploaded = '0'; if (success == 1){ result = '<span class="msg">The file was uploaded successfully!</span><br>'; uploaded = uploaded ++; if (uploaded == document.getElementById('numflowers').value){ document.getElementById(finish).style.display = 'block'; ..... }} else if (success == 2){ result = '<span class="msg">There was an error during file upload! The file has a size of 0</span><br> File: <input name="ufile[]" id="ufile[]" type="file" size="30"> <input type="submit" name="submitBtn" value="Upload">'; }else if (success == 3){ result = '<span class="msg"> We only allow .png, .jpg, .gif, .zip, .rar, and .7z files to be uploaded. If you think we should allow other please make a suggestion on the forums.</span><br> File: <input name="ufile[]" id="ufile[]" type="file" size="30"> <input type="submit" name="submitBtn" value="Upload">'; } var uploadp = "upload_process" + ups; var uploadf = "upload_form" + ups; document.getElementById('uploadp').style.display = 'none'; document.getElementById('uploadf').innerHTML = 'result'; document.getElementById('uploadf').style.display = 'block'; } Function call inside iframe (example) window.top.window.stopUpload(3, 1, test.txt)
I'm new to JavaScript and i have hit a slight problem with a project. basically, my issue is with iFrames - in particular, passing a value from an iframe to the parent page. i am trying to find a way for to pass the url of an iframe source back to the parent. hardcoding the source, or using a form within the iframe is ok - however i want to be able to view any page on the web within the frame, and for the parent page to be bale to identify what url is being loaded within it.
My main browser page has an iframe. Whenever the iframe is reloaded (updated), I want to automatically refresh the main webpage as well. How can this be done, preferably using javascript?
My site has a menu + iframe layout. Clicking on the menu link loads a page in the iframe. The iframe is set to a specified dimension.
I only have a single page that loads in the iframe. Clicking on the menu link loads a specific section on the page using the name anchor. The specified dimension of the iframe allows for the selected info to be visible.
I can create a new page for every link, but to the site's nature (its like a catalogue), I rather have it on a single page and have it called by the name anchor. I am trying to set it so that every time a menu link is clicked, the single page refreshes itself, and then goes to the anchored location. I need this for a reason.
I have tried many things but I have not got it working.
I have an instance where I do some work in a page contained in an iframe and then need to either outright move or just copy the resulting page elements into the parent page. All of the back end stuff works fine, but the Javascript just runs and doesn't produce anything. The script in question:
Code: var AddressListDiv = parent.document.getElementById("AddressListDiv"); var ListPanel = document.getElementById("ListPanel"); for(var LPC = 0; LPC < ListPanel.childNodes.length; LPC++) {
[Code]....
I think I'm running into a restriction in Javascript, but I'm not 100% sure.
I have a parent page containing an iframe. The parent page has a menu in it which opens links in the iframe. I want to highlight different bits of the menu according to which page has loaded in the iframe.
So I would like to do something like this:
1. Use PHP to extract the file name (minus 'php' at the end, of the page loaded within the iframe (which I can do fine).
2. Use javascript onload so that the iframe sends this value (say 'pagename') to the parent page when it loads any page in the iframe.
3. The parent page, having received that variable into its header, will adjust a line of css to something like: .pagename {background-color:red;}
And so the menu link for pagename.php will be colored red
4. When pagename1.php is loaded into the iframe, that will send 'pagename1' to the parent page, change the CSS in the head, and therefore change the highlighted menu item from pagename to pagename1
Is this possible? And easy? There seems to be a lot of stuff online about moving variables from iframes, but mainly in the context of form entries from an iframe to a parent, eg here:
[URL]
parent.function_name(); seems to be needed along the way. But I am not sure how to proceed.
I need to get the page to reload with the anchor in the link when it is clicked in a dropdown menu. For example if I am on 'www.domain.com/about/#2' and I then click on 'www.domain.com/about/#3' the url changes but the page doesn't reload so I need the page to reload, but keep the new anchor (#3).I gave the links with anchors a class of 'reload' and tried this:
I am looking for a generic javascript function to identify the form with in which a element exists, thus developer can avoid coding like document.forms[index].submit() - where they are sure, they want the form with in which this element exists is to be submitted. This way when forms are introduced at top level the code can remain unchanged, else every form introduce above in the DOM will result in increasing the index by one.
The code is given below. While doing so i am stuck with 2 problems P1: In the code, you can see i am giving a explicit 'break' in the code. If i don't do so the code seems to be looping. Obviously i am missing some basic.
P2: I am able to pass 'this' for anchor element by name="xy" <a href="#" name="xy"
in its onclick function by which, in the javascript function i move up the DOM.
While i am unable to do that on the anchor element given below since this function is now on the href attribute.
I create a new page and write to it. There is an anchor in the new page so that users can easily navigate to the bottom. In IE, it works fine. In Firefox, it loads the parent page into the new page....
I want to read the ID from an anchor tag and then insert it into the parent paragraph tag.This is to be repeated for all paragraphs on the page that contain anchor tags. The script is intended to run on page load.I developed the following script but it doesn't work.I got the process to work for a single paragraph but once I modifiedthe script to attempt to loop it failed.I've looked around for examples to use as learning but can't anything that matches my needs.
I have a page A and inside it I have an iframe B. B points to another php file that shows a form (so basically in the iframe we see a form). When I submit the form, I call to another page C that verifies the fields of the form and if they are ok I redirect to page X, if not I redirect to page Y. The problem is that I see page X and Y inside the iframe, and I want to see them in the parent page.
I have a page that is, essentially, a big form. Inside of this form are several iFrames which are intended to populate fields in the form of the parent (follow?). Basically, the form is for the creation of a quick banner ad spec/rough. And in the form, the user needs to position elements. Rather than requiring them to type in pixel values I used an ISMAP that returns the values to it's parent's form's appropriate field. I also do the same with a "choose the background image" - click on the image in an iframe and it is supposed to populate the appropriate field in the parent window's form.
Well, it works fine in Firefox. And, as expected, Explorer sucks and won't do any of the functions within the iframes.
I have a page which has a form and also one iframe in the same. there is a button on the parent form.when the button is clicked, i am submitting the iframe and parent both. forms are getting submitted. but when i do print_r for iframe values, it is blank
An Iframe exists inside a page (that has content exceeding the height, therefore scrollbars kick in) - normal stuff.
When I want to use anchor references inside the Iframe the parent page is affected also, in that it jumps to the top of the iframe, as though there were an anchor at that point.
I have a hidden iFrame (display:none) which I change the src attribute of to load new contents. When the iFrame has finished loading I make it visible again (display:inline). This works fine except for anchors. The iFrame will not jump to an anchor when finished loading if its hidden in FF.
