That's easy enough, just put the iframe in a div and force the height/width that you want. css solutions do not work when the content of the iframe changes (eg, when the iframe content makes ajax calls etc.)."they need their parents to have 100% height" is not true.It looks like having a parent with height: 100% does the trick.Enjoy.3 How do I make my iframe height 100%? That's it: a full-width with fixed aspect ratio. To size the, we ignore the width="560" height="315" element properties, and instead use the CSS properties width:100% height:100%.
Iframe zoom update#
Then, in the parent window, we can set a simple script to dynamically update the height of the iframe. That way, we can send a height value from the iframe to the parent window. postMessage() method, we can safely communicate between the iframe and the parent window. For the fullscreen Iframe, you have to cover the entire viewport.2 How do I change the size of an iframe dynamically? An inline frame is used to embed another document within the current HTML document. The ” iframe ” tag defines a rectangular region within the document in which the browser can display a separate document, including scrollbars and borders. The scale value will be the ratio between your window width and the dimension you wanted to set to your iframe.0 Can you fullscreen iframe? What you can do is set specific width and height to your iframe (for example these could be equal to your window dimensions) and then applying a scale transformation to it. Update: Of course, talk is nice, a working example is appreciated.As we have seen, the Zoom Out Iframe Content To Fit problemcode was solved by using a number of different instances.
Added points would be for re-dimensioning the Iframe during the mouse scroll, but at least for now this is more than enough for my purposes. Voilà! On the fly adaptation to a user zoom when using an Iframe in Flex. Then I added the following event listener on the body element of the HTML container: So in the Iframe constructor I added the following callback that can be called from Javascript:ĮxternalInterface.addCallback( “refreshIFrame”, moveIFrame) height * browserScaling) įinally, when should this resizing occur? On loading, obviously, but also when the user resizes during the session. width ĮxternalInterface.call( “moveIFrame”, frameId, iframeId, globalPt.x * browserScaling, globalPt.y * browserScaling, this. Var innerWidth:Number = ExternalInterface.call( “getInnerWidth” ) īrowserScaling = innerWidth / Application.application. * Adjust frame position to match the exposed area in the application. Using this function and the stage width I can deduce the zoom factor and apply it to my IFrame to size and position it : In the loading file I added a simple function to get the browser width: I drew inspiration from this post to write the following:
Iframe zoom code#
The main IFrame management code is inspired from this. The fix only works if the host Flash application uses “noscale”, and would need to be slightly adapted if the application didn’t take the whole window. Once I’d identified the problem, here’s how I solved it. Changing the name of the html file would somehow solve the problem. What it looked like at the offset was that on one computer only the Iframe would spill out of its bounds. Furthermore, Firefox remembers zooming for each individual page, so if perchance you zoomed in the application by accident, things will be permanently messed for that url. Zooming in Firefox messes up IFrame positioning. While working on IFrame integration for pearltrees I came across a pretty unfathomable bug that I haven’t seen documented elsewhere, so I thought I’d post about it here.
