// Single node
var component = document.querySelector('.component');
var iframe = iframify(component);// Collection of nodes
var components = document.querySelectorAll('.component');
var iframes = Array.prototype.map.call(components, function (component) {
return iframify(component, {});
});// With options
var component = document.querySelector('.component');
var iframe = iframify(component, {
headExtra: '<style>.component { color: red; }</style>',
metaViewport: '<meta name="viewport" content="width=device-width">'
});Check out the demo on CodePen.
It does not work on browsers which do not support the srcdoc attribute on <iframe> out of the box. However, there is a very good polyfill for srcdoc that you could include after iframify to make it work on these browsers.
Other major thing to note: JavaScript is not imported into the iframes, but can be with scripts option.
