How do I access an iframe from CasperJS?

Question

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?

Answer 1

Suppose we have different frames(frame1 and frame2) and we have to access different elements(like click or check if div tag exits or not) of those frames.

casper.withFrame('frame1', function() {
    var file = '//*[@id="profile_file"]';
    casper.thenClick(x(file));
});

casper.withFrame('frame2', function() {
  casper.then(function () {
     casper.waitForSelector('#pageDIV',
            function pass() {
                console.log("pass");
            },
            function fail(){
                console.log("fail");
            }
      );
   });
});
