So basically I have jquery code on a page where:

1. Open a new popup window
2. Display rails view page
3. Manipulate items on a newly opened page

Don't know what sort of solutions are there, however I thought it should be really easy.

That's the code:

// open a popup window for example /fault_books/3
popup = window.open("/fault_books/" + <%= @fault_book.id %> , "popup");

// trying to get the scope of the element
var module = $(".module-logo", popup.document.body)

// manipulating the element
$(module).hide();

• Or may be there is a way to add javascript to a created popup? – Jackie Chan Commented Jun 11, 2013 at 12:17
• Did you try: module = popup.$("body")? – Stijn Geukens Commented Jun 11, 2013 at 12:23
• Or try : module = $(".module-logo", popup.document.documentElement.outerHTML); – Mohammad Areeb Siddiqui Commented Jun 11, 2013 at 12:24
• What does happen when that code executes? Note: "nothing" is not a suitable answer; it's at best inplete and at worst an outright lie. Have you checked your browser's console/developer tools for errors? – Anthony Grist Commented Jun 11, 2013 at 12:34
• 1 You must wait for the popup content to be loaded before executing your script. Have a look at stackoverflow./a/3030893/1236044 – jbl Commented Jun 11, 2013 at 12:35

Not sure it will be cross-browser, but you may try something like :

var popup = window.open("/fault_books/" + <%= @fault_book.id %> , "popup");
$(popup.document).ready(function(){
  var module = $(".module-logo", $(popup.document))
  // manipulating the element
  $(module).hide();
});

Why don't you just put your javascript code to the generated response from "/fault_books/" + <%= @fault_book.id %>"

In that case, just do it as normal:

$(document).ready(function(){
    var module = $(".module-logo")

    // manipulating the element
    $(module).hide();
});

And don't need to do anything when opening a new window, just call:

popup = window.open("/fault_books/" + <%= @fault_book.id %> , "popup");

This solution is simple and easier to maintain as scripts are self-contained. Scripts on a page do jobs only for the containing page. Let's say, if you have another page opening the same url window.open("/fault_books/" + <%= @fault_book.id %> , "popup");. You don't have to duplicate code.
