Frames allows you to create pre-configured iframes. While providing a common interface to interact with the iframe's contents.
Frames is a simple helper function that creates a pre-configured iframe and appends it to the given DOM element while providing a nice API for interacting with the iframe.
This module assumes that it's used by a Node.js compatible module system.
npm install frames --save
The reason why we've decided to go with methods that exposes the properties vs
just exposing a
window property is that these values and their
references change when you remove and add the iframe back in the DOM.
There are 2 requirement arguments when you create a new iframe:
- The parentNode where the iframe should be appended to.
- A unique id for the iframe. This id will also be used for the
The third argument is the options argument which can be used to configure:
visible: This hides the iframe by giving it a display none and positions it outside the document using absolute positioning. Defaults to
sandbox: These values are used to set the
sandboxattribute on the iframe. It defaults to:
[allow-pointer-loc, allow-same-origin, allow-scripts, allow, popups, allow-forms]
The module exposed as single function, so it can be used like this:
'use strict';var iframe = require'frames';//// Create a new iframe and add which will be added to the `document.body`//var frame = iframedocumentbody 'foo_'+ Datenow;
The following methods are exposed on the returned object:
document method returns the
document of the created iframe. This can be
used to inject elements in the HTML of the iframe.
window method can be used to return the
global of the
iframe. This allows you to introduce new variables in the iframe as well as see
which globals are exposed within the iframe.
iframe element to initially supplied parentNode. It will only add the
element if it wasn't already in the DOM.
iframe element from the parentNode. This causes the iframe to
unload event in the browsers that support it. (Basically every
browser except older Opera browsers).
Check if the
iframe has been added to the parentNode.
Reference to the created DOM node, which can be used for all other kinds of interactions.
