jQuery Roundup
Welcome to the jQuery Plugin Roundup 23. You can send your plugins in for review through our contact form or @dailyjs.
jQuery Simple iPhone-Slide
jQuery Simple iPhone-Slide (demos and API examples) by Cain Chen displays pages in a similar fashion to iOS. Each set of pages can be set up to scroll horizontally, vertically, or in a matrix, and pages will snap into display using animations. It will try to detect swipe speed, like iOS’s standard acceleration scrolling.
Formation
Formation by Matthew Null can be used to generate forms using simple code like this:
$(document).ready(function() {
$("#new_form").formation();
$.formation.addInput({type:"text",labelValue:"First Name:",required:true});
$.formation.addInput({type:"text",labelValue:"Last Name:",required:true});
The generated forms support validation and error messages. This might seem like an odd thing to do in JavaScript, but if you’re building a single-page web app with heavy JavaScript reliance it’s very convienient. Combining this with a hot jQuery UI theme will allow you to create something pretty amazing very quickly.
Barcode Coder

Barcode Coder can generate barcodes using jQuery (they also have a version for Prototype). It supports various formats (EAN 8, EAN13, 128), and can output images to a canvas or a bunch of divs with background colours to create the effect.
$("#bcTarget").barcode('1234567890128', 'ean13', {type: 'datamatrix'});
I thought this plugin would be great if you’re generating HTML product data sheets or invoices.
