dna-engine

_An uncomplicated user interface library for cloning semantic templates_


dna-engine is a lightweight easy-to-use UI library enabling developers to rapidly build maintainable
JavaScript applications.

A) Bookstore Example

Designate templates with the dna-template class, and put the templates directly into the HTML
of your web page. 
Use the element's id to indicate the name of the template. 
Enclose data fields in double tildes ~~.

$3

``html

Featured Books

~~title~~

Author: ~~author~~

`

Then call the dna.clone() function to insert a copy of the template into the DOM. 
The supplied JSON data object populates the fields of the template.

$3


`js
dna.clone('book', { title: 'The DOM', author: 'Jan' });
`

The new clone element replaces the template. 
The original template is detached from the DOM and kept for additional cloning.

$3

`html

Featured Books

The DOM

Author: Jan

`

Need to clone the template multiple times? 
Simply pass an array of data objects into the dna.clone() function.
