Jewel

Operate with DOM elements like they're ActiveRecord models.

Getting Started

Dependencies

• jQuery

Compatability

• Safari
• Google Chrome
• Firefox
• Opera
• IE - not tested

Include Jewel (0.7kb minified and gzipped):

<!-- jQuery must be included before that -->
<script src="jewel.min.js"></script>

Usage

Let's say we have such HTML:

<div id="posts">
	<div class="post">
		<h1>First title</h1>
		<p>First body</p>
	</div>
	<div class="post">
		<h1>Second title</h1>
		<p>Second body</p>
	</div>
</div>

Now, we need to define Post model:

var Post = Jewel.define('#posts', { // selector for a wrapper element
	keys: {
		title: 'h1', // selector for title, h1 in our case. Will be used as #posts .post h1
		body: 'p', // selector for body. Will be used as #posts .post p
	},
	template: function(fields){ // function that returns HTML for new posts, you can use custom templating engine here.
		return "<div class=\"post\"><h1>" + fields.title + "</h1><p>" + fields.body + "</p></div>"
	}
});

That's it! We can start doing cool stuff:

// Finding all posts
var posts = Post.all;

// Finding first post
var post = Post.find({ limit: 1 })[0];

// Finding second post

post = Post.find({ skip: 1 })[0];
post.title; // "Second title"

// Updating post

post.title = 'Last post';
post.save();

// Removing post

post.remove();

// Removing all posts

Post.remove();

// Creating new one

post = new Post;
post.title = 'Latest post';
post.body = 'Latest content';
post.save(); // will be prepended to #posts
