I'm trying to embed our page on a clients site, it works great in a browser and our media queries do a great job, but when inside an ifarme on an idevice, the embedded page doesn't act responsively and displays in the biggest media query size (>870px wide) and it looks really small...
Any idea why this ahppens or how to fix it?
We learned it the hard way.
inside iFrame,
the media query is not aware of the parent window screen size
in some browsers, the iFrame actual height/width will be more than the CSS width/height shown in the parent page
In short, media query is not fully compatible with iFrames.
We resorted to implementing our own media query like behaviour through javascript.
In summary it is like below,
the parent page loads iFrame [in a popup in our case, after user clicks a link]
the iFrame sets up onmessage event listener
the parent page initiates postMessage to iFrame
the iFrame receives parent window width, height from parent page and any other necessary info
the iFrame manually re-adjusts the layout through javascript
Hope this helps.

There are two Pages A and B. On a small device, A should be displayed by default and B should be available with a swipe event. On a larger device, both pages should be displayed next to each other.
I really have no clue how to approach this. I tried using another library (iDangero.us swiper) for the swipe, but I am also using knockout.js with a lot of dynamic controls and using swiper in this scenario was quiet a mess (it is tough enough to sync knockout.js and jQuery Mobile). So I plan to fall back to using jQuery Mobile pages and transitions.
You can Use Iframes if you are familiar with them.
Iframe touch page scrolling may be an issue. But There are various easy solutions.
Pages structure
main-page.htm
tablet-page.html
page1.html
page2.html
.
Jquery to detect screen viewport width and redirect to the tablet-view if needed.
in main-page.html file add
$(window).onload(function() {
var wi = $(window).width();
if (wi => 900){
window.location.href = 'tablet-page.html';
};
});
tablet-view.html has 2 Iframes with page1 and Page2 html links.
use some css to auto resize the iframes to 50% 50% view. A container may be need.
result
if its tablet size then
excuse the bad graphics
My upcoming mobile web project requires viewing dynamically chosen pdf files inside the webpage. I am using iFrame to display the pdf file and the file can be scrolled using two-finger scrolling. But the problems I am facing are:
The first page of the file is not displayed completely on the iPad and gets cut off along the width unlike when I view it on the desktop browsers where the first page of the pdf is always entirely displayed although zoomed out to fit in the iFrame area.
There is no visual indication for the users that the pdf document can be scrolled, i.e., there is no scroll bar on the pdf document.
The controls (page navigation, zoom etc.) for the pdf viewer (Adobe reader) don't appear on the document unlike when I see it on the desktop browsers.
What is the best way to achieve what I am trying to do? Do any of you experts know any solutions/workarounds to the problems I am facing? An entirely different approach using anything other than iFrame can also be considered.
The reason why the pdf should be inside the html page is that, the list of pdf files will be on a menu bar on the left side of the page and the user can click on any of them to view on the same page. Ideally, they will have the capability to toggle between full screen view and that view.
Any help is appreciated.
I created a tiny JavaScript module that helps you to show a PDF inline and be able to scroll it. But I also couldn't figure out a way to make it fit the total width of the parent container.

I came across this Recommended way to embed PDF in HTML? while researching on the web to find an answer.
The mentioned link discusses about some options that I can use and the google document viewer works for me though don't know if there is anything (like data limit) I need to be aware of before using it on the website. Also I have no idea if it is a good solution (though the full screen mode is not available, but zoom-in/zoom-out and next/prev page buttons are there are show up in the mobile safari on the iPad) to use for an web app that will be run on the iPad.
Anyway, I will keep researching for a better solution and if i don't find any, I'll stick to the google document viewer.
The issue appears to be a bug with Safari on the IPad.
I didn't find a solution for embedding the pdf in html but I did find this:
If you return FileStreamResult from your controller action instead of a view, the pdf will open in a new tab, it's not embedded html but at least your user is not having to download files and open them manually.
I had the same problem of the pdf not being displayed completely. The only thing I found to fix this was the change the size of the div containing the pdf.
For example if the element containing the pdf is a div then I change its width to any value and the rollback to the value it had before. Changing Width or height any one works.
Sometimes I had to wait a little using a setTimeout before calling my resizable method
I'm making a mobile HTML5 app. I've disabled scrolling (and enabled it on certain parts) and it's all good and well, but the problem starts when I embed a Youtube video through an iFrame. It seems that when a user presses an iframe, the whole page scrolls and I can't seem to find a way around this. Adding event listeners does not work.
You really can't control what happens in the iframe.
But if you want to be a little clever you can put elements directly over the iframe, like a div or transparent canvas or whatever you want, that will catch all of the events so that the user simply cannot press the iframe.
Not the most ideal, it means users cant press the buttons on the youtube video, but its probably your only real option.
I loaded the Like Box iframe code generated on Facebook into an UIWebView on my iPhone App. It works well, but when I scroll, it scrolls the UIWebView itself, and not the content inside the iframe. How can I block the UIWebView from scrolling (i.e the UIWebView takes the fullscreen frame) and allow the overflowed content of the iframe to scroll instead ?
ps : I tested a simple .html in MobileSafari.app and I have the same problem
You use two fingers in the like box instead of one. Then it scrolls.
You won't have much control over a plugin that is rendered as an iframe due to cross domain restrictions and they do not give many options to customize the appearance.
You could replace it with a Facebook like button. Then below it, you could add code that reads and displays the Fan Page feed using the graph api's page's feed connection (/pageId/feed). This would give you full control over the rendering and still gives the user the option to like your page. To improve performance of this solution you could use the Facebook real-time updates API to get notified when new updates get posted to the page and then you could pull those down and cache them.
PLEASE NOTE: This is not a "use two fingers to scroll" problem. Whether it is one finger, or two, or three, or the whole hand, for some reason our iframe does not scroll on an iPad. :)
Here is the scenario:
In our web application, which is built using EXT-GWT, we have a few windows that open as (maximized) pop-ups and present some forms to the users. These forms, which are most of the times external, are rendered in an iFrame and some of the forms have their content collapsed at the initial load - the user can choose to expand any section of the form, fill it in and submit. Now everything works fine except the scrolling in iPad. After the iframe's content is loaded and collapsed (collapsing is done using JS on the client side, basically, the content loads as expanded by default and then is collapsed by JS) iPad just fails to provide scolling to the iframe. Even after the content of the iframe is expanded the iframe does not get any scrolling.
As of now, we have solved this problem by increasing the height (using JavaScript) of the EXT-GWT window to the size of the expanded iframe body content. This makes the whole window scrollable, instead of just the iframe within the window. While it works, the window becomes way to big, so I was wondering if there is any better way for us to provide scrolling to the iframe.
Thanks for the help,

For iOS devices you need set overflow: auto; or the scrolling won't work. For my web apps I used fancybox to display iframes modally and once I change the overflow setting in the css file the two finger scroll worked perfectly on the iPad.
After trying (almost) everything, I have come to the conclusion that increasing the GWT window height to the iframe.body.height is the only solution for getting the window/iframe to scroll on iPad. Hopefully, this will help someone in future.
I´m pretty new to GWT, but for me it worked like this:
The parent-div of the iframe has a class in my case, x-component.
I made an entry to my css file like this:
.x-component{-webkit-overflow-scrolling: touch; overflow:auto;}
It works as well if I set these entries not to the class, but to the div-element itself.
Hope that helps
