The load event. It is triggered when the iframe is fully loaded. In other words, all static assets have been downloaded, and all the elements in the DOM tree have fired their load event. The error event that is triggered when the loading failed. Seems like the recommend work around for this since its not ajax is ios 13 font ttf use an iframe and listen from the onload or done event to determine when the file has actually shipped to the client from the server.

Use Dev Tools or the Performance api to check if the load event is being fired at all. Suppose that a user creates a webpage. Now he has a webpage, which contains an IFrame and a Button. How are we going to make this possible? How can I detect that an iframe on my page starts to load a new page? A simpler problem might be that the document inside the iframe has not loaded yet when you add the event listener.

If it then loads, your listener will be gone. So you should treat this as an entirely separate window, wait for it to load, then add your listeners. Because an iframe is a document, you can use most global event handlers. When you are initiating the iframe, two of them come in handy to improve the experience, like displaying a spinner or a specific message to assist the user:. Is there any way to access things happening in that iframe from the developer console? Currently evaluation in the console is performed in the context of the main frame in the page and it adheres to the same cross-origin policy as the main frame itself.

This means that you cannot access elements in the iframe unless the main frame can. In this case console. No related posts. Table of Contents 1 How to listen to iframe load complete event stack?Recently I needed to add drag-and-drop support for an element that contained iframe.

Try dragging the box with faster mouse movements. Whenever pointer gets into the iframe element with red background dragging stops.

This behavior is caused by how events are handled in iframe. According to the specification event bubbling is allowed only within a single document. This upward propagation will continue up to and including the Document.

Document Object Model Events: Event bubbling. Since iframe represents a separate document therefore all events including mousemove event will terminate at the root of the iframe document and will not travel across the boundary into the host document. At first I thought that the solution would be to pass all mousemove events from iframe to parent window.

However after finding this answer on StackOverflowthe solution turned out to be much easier. You need to disable mouse events including mousemove event for iframe by setting pointer-events CSS property to none when dragging starts and restore it to auto when dragging stops. It is worth noting that pointer-events CSS property is not supported in IE 10 or lower, see this page for more information.

Broadly, one window may obtain a reference to another e. The receiving window is then free to handle this event as needed. The arguments passed to window.

A reference to the window that will receive the message. Methods for obtaining such a reference include:. Data to be sent to the other window. The data is serialized using the structured clone algorithm. This means you can pass a broad variety of data objects safely to the destination window without having to serialize them yourself.

If at the time the event is scheduled to be dispatched the scheme, hostname, or port of targetWindow 's document does not match that provided in targetOriginthe event will not be dispatched; only if all three match will the event be dispatched.

This mechanism provides control over where messages are sent; for example, if postMessage was used to transmit a password, it would be absolutely critical that this argument be a URI whose origin is the same as the intended receiver of the message containing the password, to prevent interception of the password by a malicious third party.

Failing to provide a specific target discloses the data you send to any interested malicious site. Is a sequence of transferable objects that are transferred with the message. The ownership of these objects is given to the destination side and they are no longer usable on the sending side.

A window can listen for dispatched messages by executing the following JavaScript:. The origin of the window that sent the message at the time postMessage was called. Note that this origin is not guaranteed to be the current or future origin of that window, which might have been navigated to a different location since postMessage was called.

A reference to the window object that sent the message; you can use this to establish two-way communication between two windows with different origins. If you do not expect to receive messages from other sites, do not add any event listeners for message events.

This is a completely foolproof way to avoid security problems. If you do expect to receive messages from other sites, always verify the sender's identity using the origin and possibly source properties.

Having verified identity, however, you still should always verify the syntax of the received message. Otherwise, a security hole in the site you trusted to send only trusted messages could then open a cross-site scripting hole in your site. A malicious site can change the location of the window without your knowledge, and therefore it can intercept the data sent using postMessage.
