iframe-script

A basic helper module to execute a function inside an IFRAME. This is helpful if you are building a service script that is meant to be executed on 3rd party sites and you want to avoid any possible conflicts.

Installation

npm install iframe-script

Usage

var iframeScript = require('iframe-script');

// this function gets stringified and executed inside an iframe,
// it doesn't preserve the scope
function frameFunction(opts) {
  return {
    printFoo: function() {
      console.log(opts.foo);
    }
  }
}

iframeScript(frameFunction, {foo: 'hello world'}, function(err, results) {
  results.printFoo();
});

API

iframeScript(fn, opts, callback)

• fn is a function(opts) that gets passed into the iframe. The function gets stringified and it's expects to return results that are then passed into the callback
• opts object that is passed by reference as first argument into the fn.
• callback is a function(err, results) that gets called when fn is executed.

Testing

npm test # runs test suite once
npm run dev # starts karma in watch mode
