![]() ![]() Used to allow submission of the form which otherwise is blocked. Used to apply extra restrictions for the content of a frame. Used to to define the web address of the inline frame page. Used to specify the width of embedded frame (default width is 300 px). Used to specify whether an iframe should have a border or not. Used to specify the height of the iframe (default height = 150 px). Iframe attributes:īelow are the various attributes used with an HTML tag. In the above example, we embedded a YouTube video on a webpage. If required, modify the height, width, and other properties of the video.Copy and paste the generated HTML code in the desired HTML file.Click on the SHARE video option and than on the Embed option.To add a YouTube video on a webpage follow the below steps: The course of action that you select will depend greatly on how much of a priority this issue is to you.In the above example, the respective link opens in the iframe on clicking, since the specified target of the respective link matches the name of the iframe. There are a number of ways to set scrollbar options on an iFrame, from simple to complex. Window.attachEvent("onmessage", resizeIFrame) Window.addEventListener("message", resizeIFrame, false) Var myIFrame = document.getElementById('myIFrame') If (event.origin != loc.protocol + '//' + loc.host) return ![]() The iFrame’s dimensions are reset according the the event data’s w and h properties – that’s the first argument passed to the postMessage() function above: Inside the function, the first line verifies the sender’s identity using the origin property in order to thwart cross-site scripting attacks. In the parent document, we need to attach an event handler to the postMessage event that accepts an event as its argument. This is child2this is child2this is child2this is child2this is child2this is child2this is child2this is child2this is child2this is child2 If you want it the other way around, you have to apply the rules dynamically via scripting, for instance: function setIframeSize(iframe), loc.protocol + '//' + loc.host) In essence, the child document is telling the parent how to display it. Instead, you have to apply the CSS values to the child document’s or tag. However in practice, this doesn’t have any effect. It would seem evident that if you wanted to show a vertical scrollbar and suppress the horizontal one you would apply a style of “overflow-y:scroll overflow-x:hidden” to the element. It replaced the “yes” and “no” values with “scroll” and “hidden” (“auto” remained), while offering additional values of “visible”, “initial”, and “inherit”. It could be set to “auto”, which means that scrollbars appear if needed (the default behavior), “yes” (scrollbars are always shown, whether needed or not), and “no” (scrolbars are never shown, even when needed).Īlthough still supported in all major browsers, the scrolling attribute has largely been eclipsed by the CSS overflow, overflow-x, and overflow-y CSS properties. Originally, iFrame scrollbars were set using the scrolling attribute. Provided you’ve got access to the iFrame content, you can pull it off. A great idea in theory, but the devil’s in the implementation details here. Sometimes the solution is to set the dimensions of the iFrame to that of the containing document so that scrollbars are not needed. There are ways of overriding this behavior, but not without the risk of having scrolbars when not needed, or worse, no scrollbars when required. Display iFrame Contents without ScrollbarsĬontent that is presented in an iFrame appears with a vertical scrollbar if the length of the child document exceeds the height of the iFrame and with a horizontal scrollbar if the child document elements won’t wrap to the width of the iFrame. ![]()
