Insert Script Tag Or Code While Child Frame Loads?
Apr 28, 2010
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.
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 have a use case in which I need to insert an IFrame as a child to an existing DIV just after the page load completes. That is, the request to fetch content for this Iframe should go to the server "after" all the media in the page has loaded, basically after the page "load" event and not the document ready event.My document structure is as follows:
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.
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 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 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:
i have a javascript bookmark to log me onto my schools site[URL].. it works fine if the page is already open, but with using the link to open the page, it runs the remaning script before the page loads and it doesn't work. is there any way to fix this withou using setTimeout()
I want to - after the page has loaded - detect a text string in the code..Simply put I want javascript to detect a text string in the source code and return it to me -- AFTER the page is fully loaded.
The commas in the (Hello,World:,check1,check2,and,check3') part of the code are inserting a space between the words. But I also want to insert comma between check1, check2, and check3. I have tried the html ascii code for comma that is ",". I also tried the escape sign (as below. None of these codes worked. Does anyone have any tips?
I was wondering if anyone could help me with the javascript code that inserts a random number into the banner code. I had an example a month ago that worked, I stopped using it for a while, and now the forum I had gotten it from has deleted that post. I've tried to take other examples and make my own, but the banner doesn't display correctly. I'm not sure what I'm doing! Code:
I have a website with a floating cart and it loads fine and works almost flawlessly . However, when a person has a bunch of items in their cart, and they want to minimize it for the rest of their browsing experience, every time a new page loads, or a refresh happens, the floating cart un-minimizes and expands out fully again displaying all the items.
This can become very annoying during the shopping experience when you have a bunch of items loading and just taking up space in the browser. Therefore, I am wondering if their is some html or script that would save the minimizing in the floating cart, and carry it over to the next page, and the rest of the browsing on site?
I need a JavaScript code to load pages into another frame. The thing is, I want to control the pages that are loaded using an external javascript (.js) file.
For a widget I made, I have a dropdown select menu. It is constrained to a very small width and IE does not auto expand on click. I wrote a simple javascript to handle this but I run into two problems. The onmouseout function is fired when I click into a child node, and the onmousedown of the <option> tags doesn't work in IE. The code works fine in all other browsers.
var wid; var campaign_i = 0; function campaignWidget_capture(myID){ wid=document.getElementById(myID).style.width; campaign_i++; } function campaignWidget_SubDes(myID,state){ if(state==0){ [Code]...
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 want to have a main image in place and when you click on 1 of the 3 frame options the frame changes showing a preview. Also I would like the add to cart button change its code to add the correct item as well.
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

i try this but it's not worked anyway how i can do this.
i need to pass the data in the textfields from the left frame to the textfields in the right frame of my frameset. (ex: dslnum of frame1 will be pass to txtDSLTN of frame2)[URL]
I have two frames (frameset, let's call it frame1 and frame2). Frame1 has links..., and frame2. When some link in frame1 is clicked, it must be changed content of the frame2. Here's example: click. How to do that? (I don't see any javascript code)
I have a little problem, I structure my site with a main page index.html with a frame in the central whit name CENTRALE, so every other page I will open within this frame. Now I need to have a direct link to these internal pages, give an example I wish it were possible to go to the page clothing giving a direct link to that section of the site type www.indirizzo.com / clothing.html because the state of things if I take the 'direct address to that page I open only the part inside of the frame, but I wish I would open inside the "main frame, there is a solution in javascrip to overcome this problem?
