EDIT: to explain further, edit. I seem to recall running into a problem when I was trying to communicate with an iframe same domain etc. The trick I found is to do the binding inside the frame and bind to functions in the main window. Something like this in edit. I realise this does not exactly fit into the way you were trying to do it, but the same effect is achieved. From what I understand of javascript and iframes, in practice it's easier to communicate with a parent than it is to communicate with an iframe.

If you really need two-way communication you could going on the example above use the return value of the function funcKey to pass data back into the iframe. One of the most annoying things about javascript is that document. This distinction is probably why you're running into cross-browser issues. You'll likely need to mess around with different ways of accessing the iframe contents until you find one that works correctly.

I want to listen for that call from that image within that iframe or perhaps the onclick on that particular image?

How do I pass the events that occur in the document within the iFrame up to the parent? Or if I need to add a listener for the onclick event on the image within the iFrame, how does that get back up to the parent? Thanks in advance. When the event fires in the iframe, you use js in the iframe to call the function in the parent. In any window, when you call a function on the same page, you are really doing this:.

When we access something inside the embedded window, the browser checks if the iframe has the same origin. The iframe. It triggers when the embedded window fully loads with all resources. But if windows share the same second-level domain, for instance john. Now they can interact without limitations. Upon its creation an iframe immediately has a document. But that document is different from the one that loads into it! If we set any event handlers on it, they will be ignored.

The right document is definitely at place when iframe. But it only triggers when the whole iframe with all resources is loaded. An iframe may have other iframes inside. The corresponding window objects form a hierarchy. We can use the top property to check if the current document is open inside a frame or not:.

ChandranaRDeshmukh96 Angular separates components in a way that makes it a difficult for them to access each other. Something like document. Otherwise, you may have to make a service to give yourself access to that iframe element. Skip to content.The window.

Normally, scripts on different pages are allowed to access each other if and only if the pages they originate from share the same protocol, port number, and host also known as the " same-origin policy ". 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.

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. Any window may access this method on any other window, at any time, regardless of the location of the document in the window, to send it a message. Consequently, any event listener used to receive messages must first check the identity of the sender of the message, using the origin and possibly source properties.

This cannot be overstated: Failure to check the origin and possibly source properties enables cross-site scripting attacks. As with any asynchronously-dispatched script timeouts, user-generated eventsit is not possible for the caller of postMessage to detect when an event handler listening for events sent by postMessage throws an exception.

For example, if postMessage is invoked in an event handler, that event handler will run to completion, as will any remaining handlers for that same event, before the MessageEvent is dispatched. The value of the origin property of the dispatched event is not affected by the current value of document. For IDN host names only, the value of the origin property is not consistently Unicode or punycode; for greatest compatibility check for both the IDN and punycode values when using this property if you expect messages from IDN sites.

The value of the origin property when the sending window contains a javascript: or data: URL is the origin of the script that loaded the URL. The other properties have their expected values.

It is not possible for content or web context scripts to specify a targetOrigin to communicate directly with an extension either the background script or a content script. Web or content scripts can use window.
