I have a webpage with an iframe. I'd like to access the contents of the iframe using CasperJS. In particular, I need to click buttons and fill a form. How can I do that?
The main webpage is main.html:
<html><body> <a id='main-a' href="javascript:console.log('pressed main-a');">main-a</a> <iframe src="iframe.html"></iframe> <a id='main-b' href="javascript:console.log('pressed main-b');">main-b</a> </body></html> The iframe is:
<html><body> <a id='iframe-c' href="javascript:console.log('pressed iframe-c');">iframe-c</a> </body></html> My naïve approach:
var casper = require('casper').create({ verbose: true, logLevel: "debug" }); casper.start("http://jim.sh/~jim/tmp/casper/main.html", function() { this.click('a#main-a'); this.click('a#main-b'); this.click('a#iframe-c'); }); casper.run(function() { this.exit(); }); Doesn't work, of course, because the a#iframe-c selector isn't valid in the main frame:

A hack that involves poking into phantomjs directly would be fine, but I don't know what to do there.
I'm using CasperJS version 1.0.0-RC1 and phantomjs version 1.6.0.

Set the iframe to the appropriate width and height and set the scrolling attribute to "no". If the area you want is not in the top-left portion of the page, you can scroll the content to the appropriate area.
Spent forever looking for this, and of course I found the answer minutes after posting the question.
I can use the new frame switching commands added to phantomjs in this commit. Specifically, the this.page.switchToChildFrame(0) and this.page.switchToParentFrame() functions. It appears undocumented, and it also seems that the methods have been changed for upcoming releases, but it does work:
var casper = require('casper').create({ verbose: true, logLevel: "debug" }); casper.start("http://jim.sh/~jim/tmp/casper/main.html", function() { this.click('a#main-a'); this.click('a#main-b'); this.page.switchToChildFrame(0); this.click('a#iframe-c'); this.page.switchToParentFrame(); }); casper.run(function() { this.exit(); }); From 1.0 you can use withFrame
casper.open("http://www.example.com/page.html", function() { casper.withFrame('flashHolder', function() { this.test.assertSelectorExists('#the-flash-thing', 'Should show Flash'); }); }); If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
