Selecting DOM elements with inAppBrowser - Cordova

Question

It seems I can't select DOM elements from a website I've loaded using the inAppBrowser plugin. When I log document.getElementById("input") it's null. The resources I've read on this have treated selecting elements as trivial, but I seem unable.

Here's the code I'm using:

var obj = {
      link: "https://www.foolink.com",
      input: "barInput",
      func: function(obj) {
          document.getElementById("input").value = obj.input;
      }
}

var ref = cordova.InAppBrowser.open(obj.link, "_blank");
ref.addEventListener('loadstop', function() {

  ref.executeScript({code:obj.func(obj)})

})

Has anyone else encountered this before? Using jquery to get selectors on gives me selectors from the index.html file, not the inAppBrowser window.

*edit: currently using inAppBrowser 1.4.0 and cordova 6.0.0

Answer 1

Frix33 got the gears turning with his answer, but I don't think it specifically identifies the problem so posting my own. The script injected into the page must be a STRING or else it is just executed by the app, which is a different document hence the null result before. It works if you replace {code: obj.func(obj)} with:

var codePass = "document.getElementById('input').value = '"+ obj.input +"';"
var ref = cordova.InAppBrowser.open(obj.link, "_blank", "location=yes");
ref.addEventListener('loadstop', function(event) {

   ref.executeScript({code:codePass})

});

You can pass as many script lines as needed using that format.
