Hi,

first, excuse me for my poor english, but I'm french.

I load an external page into a frame : final Frame frame = new Frame(url);

The external page is from a public website.

Can I send event to an element on this page, like click on a button, or fill a textfield ?

Thx for help

I try to explain better my problem.

I load a frame with an url (like www.google.fr)

How can I fill the text field (id="gbqfq"), and send click to search button (id="gbqfba") ?

Do you understand what I mean now ?

Thx

You can use the DOM class to access elements by id. I am pretty sure your iframe is accessible in the manner.

http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/DOM.html

If not, check out the JSNI code used by Print-it to access a hidden iframe and use it for printing purposes.

You can't.

Wouldn't it be great if loading a website (which could just be an ad actually, so something that I didn't even *chose* to see) would load Twitter in an hidden iframe, fill the "compose" input and then programmatically click the "Tweet" button? (or variations along the way of Facebook, G+, GMail, or maybe buying things from Amazon, making bids on eBay, etc.)

On the other hand, if you are loading iframe from the same domain, and have full control of iframe content you can use window.postMessage api for child - parent communication.

You will need to implement some JSNI methods in order to accomplish this in GWT.

If it's from the same origin, you don't need postMessage. postMessage was specifically made for cross-origin communications.

See http://dev.w3.org/html5/postmsg/#web-messaging and http://www.whatwg.org/specs/web-apps/current-work/multipage/web-messaging.html#web-messaging for the spec, and http://html5demos.com/postmessage2 for a demo.

or use Elemental.

I doubt it'll solve Laurent's use case though: he was talking about loading a third-party site, and never mentioned that site was "friendly" to the "calling GWT app" (he used Google as an example)

Thanks Thomas for clarification of messaging api. I believed that it is working only on same domain and that it is build just to standardize communication.

Best,
Milan

ARRRGGG !

Thank you all for your search and help.

I don't know how to workaround my problem.

So, I'll search (alone, again, ;-)
If I find anything, I'll tell you

Best,

Laurent
