Injector.js

About

Injector.js is a helper library to ease the pain of mixing asynchronous JavaScript and dynamic content building with third party scripts which insist document.write is still a good idea.

This script in beta but works on major browsers (IE, Firefox and Chome).

Usage

See examples/index.html for usage.

Methods

• Injector(options) Constructor.

• Injector.setContainer(element) Set the parent container that HTML should be injected into. Can also be set via options.container.

• Injector.setSibling(element) Set the node which HTML should be injected before. Can also be set via options.sibling.

• Injector.eval(script) Evaluate inline script, document.write calls will be captured and output will be injected either at current position.

• Injector.insert(html) Insert HTML at current position, evaluating scripts manually and overriding document.write calls.

• Injector.oncomplete(callback) Callback to execute after insert() or eval()

Issues

• Calling Injector.insert() or Injector.eval() while scripts are still being inserted will cause issues.

Todo

• Cross browser testing.

• Convert to standalone module rather than class instance.

• Add queue, so that insert() and eval() can be called at any time without side effects.
