Detect if a string is a data URL. Doesn't try to parse it or determine validity, just a quick check if a string appears to be a data URL. See http://jsfiddle.net/bgrins/aZWTB/ for a demo.
// Detecting data URLs
// data URI - MDN https://developer.mozilla.org/en-US/docs/data_URIs
// The "data" URL scheme: http://tools.ietf.org/html/rfc2397
// Valid URL Characters: http://tools.ietf.org/html/rfc2396#section2
function isDataURL(s) {
return !!s.match(isDataURL.regex);
}
isDataURL.regex = /^\s*data:([a-z]+\/[a-z]+(;[a-z\-]+\=[a-z\-]+)?)?(;base64)?,[a-z0-9\!\$\&\'\,\(\)\*\+\,\;\=\-\.\_\~\:\@\/\?\%\s]*\s*$/i;

Prevent errors on console methods when no console present and expose a global 'log' function.

Javascript log Function

Every time I start a new project, I want to pull in a log function that allows the same functionality as the console.log, including the full functionality of the Console API.

There are a lot of ways to do this, but many are lacking. A common problem with wrapper functions is that the line number that shows up next to the log is the line number of the log function itself, not where log was invoked. There are also times where the arguments get logged in a way that isn't quite the same as the native function.

This is an attempt to once and for all document the function that I pull in to new projects. There are two different options:

  • The full version: Inspired by the plugin in HTML5 Boilerplate. Use this if you are writing an application and want to create a window.log function. Additionally,
