![]() ![]() The iframe has an onload event on it, which calls a function from the FrameManager class, which we’ll need to call in the : Īnd here is the magical FrameManager class: var FrameManager = else if ((document.body) & (document.body. In our case we’re just reading in that information and using it to do the resizing. However, these two elements do slightly different things. You can’t really do anything malicious with just a hash tag. Like iframe, the embed element is used to embed an external resource in a web page. It is unlikely that this will ever break, so it’s not really a “hack”. This circumvents the security restrictions. The work-around is using hash tags in the URL to relay information back and forth. ![]() So this isn’t going to work for an iframe of . Y ou can use JavaScript’s contentWindow property to force iFrame to automatically adjust its height based on the content it contains, so that no vertical scroll bar appears. You’ll need to run JavaScript on both ends. This solution presupposes that you have control over both the hosting site and the source site. The following technique doesn’t require the middle man thing though, which is why it’s closer to ideal. This may have been inspired by a technique by John McKerrell. Same-domain iframes aren’t subject to the same restrictions so it’s far easier.Īdam Fortuna explored some options using kind of a man-in-the-middle idea. To do this with an iframe with source content on the same domain, you can do this. To this day, there are eight attributes we can use to customize the behavior or styling of an iframe. Warning: the demo kinda freaks out WebKit browsers like Safari and Chrome, see issues below. The results are the closest I’ve been able to come yet: Full iframe height will be set only if iframe source page sends its height data with parent.postMessage() method. I recently came across a solution from Kazi Manzur Rashid (about two years old now) that looks pretty solid so I thought I’d try it out. I’ve literally tried to work on different solutions for this for years and always came up short. In this iframe generator, you can change width, height, margin width, margin height of iframe, you can also disable and enable border, you can change border type to none, hidden, solid, dotted, dashed, border size and also you can change the border color and also make iframe responsive. These security measures are in place to prevent all the black-hat kind of things you could do if you did have JavaScript access to the innards of an iframe. It can be very frustrating, for example, if you just want to do something normal and white-hat like adjust the height of the iframe to fit the content inside it. For example, you can’t have JavaScript access anything inside it. ![]() this code make this tag (iframe) width screen width and it's height screen height - i am sorry mikel at 4:36 4 screen is the actual screen and not the browser window, so in most cases the browser window will be smaller than the screen size. ’s which display content from different domains have security measures in place to prevent all sorts of stuff. screen.width to get the screen width value. ![]()
