That makes me sad. 48002 4 ian 2011-05-04 23:34:21 +0000 What would make you happy? 48125 5 ayg 2011-05-05 22:56:30 +0000 Not base64-encoding it, so it's readable in the source. base64 data URLs are only really needed for binary formats, not HTML. So just do something like <a href="data:text/html,<!DOCTYPE HTML> <html lang=en> <head> <title>Pretty Glowing Lines</title> </head> <body> <canvas width=800 height=450></canvas> <script> var context = document.getElementsByTagName('canvas')[0].getContext('2d'); var lastX = context.canvas.width * Math.random(); var lastY = context.canvas.height * Math.random(); var hue = 0; function line() { context.save(); context.translate(context.canvas.width/2, context.canvas.height/2); context.scale(0.9, 0.9); context.translate(-context.canvas.width/2, -context.canvas.height/2); context.beginPath(); context.lineWidth = 5 + Math.random() * 10; context.moveTo(lastX, lastY); lastX = context.canvas.width * Math.random(); lastY = context.canvas.height * Math.random(); context.bezierCurveTo(context.canvas.width * Math.random(), context.canvas.height * Math.random(), context.canvas.width * Math.random(), context.canvas.height * Math.random(), lastX, lastY); hue = hue + 10 * Math.random(); context.strokeStyle = 'hsl(' + hue + ', 50%, 50%)'; context.shadowColor = 'white'; context.shadowBlur = 10; context.stroke(); context.restore(); } setInterval(line, 50); function blank() { context.fillStyle = 'rgba(0,0,0,0.1)'; context.fillRect(0, 0, context.canvas.width, context.canvas.height); } setInterval(blank, 40); </script> </body> </html>">pretty glowing lines</a> Or is that invalid for some reason? I don't see why it should be. It works fine in browsers. 48126 6 zcorpan 2011-05-05 23:10:22 +0000 Pretty sure that's not a valid URL (for one it has spaces in it). V.nu says Error: Bad value data:text/html,<!DOCTYPE HTML>... for attribute href on element a: Illegal character in path component. 48187 7 ayg 2011-05-06 16:03:46 +0000 Why should it not be a valid URL, if it works in all browsers (assuming they support data URLs at all in this situation)? 48232 8 ian 2011-05-06 20:18:40 +0000 The script is _right there_ in the spec already. 48242 9 ayg 2011-05-06 20:42:35 +0000 Um. Well, okay, that's true. 52708 10 mike 2011-08-04 05:03:46 +0000 mass-move component to LC1
