better-dom: Live extension playground
Build Status Coverage Status Bower version

This library is about ideas. After some time of using jQuery I found that it's just too big, has lack of features I need and some desicions of the API design is debatable. In particular live extensions was one of the main ideas that encouraged me to build a new library from scratch.

API DOCUMENTATION

Sauce Test Status

Features

Installation

The simplest way is to use bower:

$ bower install better-dom

This will clone the latest version of the better-dom with dependencies into the bower_components directory at the root of your project. Then just include the script below on your web page:

<script src="bower_components/better-dom/dist/better-dom.js"></script>

Documentation

Contributing

In order to modify the source code you have to have gulp installed globally:

$ npm install -g gulp

The project uses set of ES6 transpilers to compile an output file that works in current browsers. You can use the commend below to start development:

$ npm start

After any change it recompiles build/better-dom.js and runs it through the unit tests.

Notes about old IEs

For IE8-9 support you have to incude an extra file via the conditional comment below before end of the <head> on your page:

<html>
<head>
...
<!--[if IE]>
    <script src="bower_components/better-dom/dist/better-dom-legacy.js"></script>
<![endif]-->
</head>
<body>
    ...
    <script src="bower_components/better-dom/dist/better-dom.js"></script>
</body>
</html>

This file contains several important addons for IE8-9:

  1. es5-shim is used to polyfill/fix missed standards-based functions
  2. html5shiv solves issue with HTML5 tags in IE8
  3. polyfill/fix for the input event in IE8-9
  4. change event fix for checkboxes and radio buttons in IE8
  5. fix for bubbling of the submit and reset events in IE8

Later the library downloads better-dom-legacy.htc file. This file helps to implement live extensions support and should be in the same folder with better-dom-legacy.js. And that fact applies several important limitations which you should be aware of in case when IE8-9 support is needed:

1) HTC behaviors.aspx) have to serve up with a content-type header of “text/x-component”, otherwise IE will simply ignore the file. Many web servers are preconfigured with the correct content-type, but others are not:

AddType text/x-component .htc

2) IE requires that the HTC file must be in the same domain with as the HTML page which uses it. If you try to load the behavior from a different domain, you will get an “Access Denied” error.
