Writing Code 39 Barcodes with Javascript

Lou previously showed how easy it is to generate Code 39 Barcodes using the imaging toolkit, DotImage, now he shows how to do it in pure JavaScript. "I wanted to make it easy to deploy so I don't use images. Luckily, 1D barcodes are easy to make with just colored table cells, so I just generate a one row table with a column for each bar. I set the width of the column to be the width of the bar and then color it either black or white."
