Map file extension to mimetypes

file-ext-to-mime.js

// This method takes in one argument, a filename, and looks up its extension in the dictionary.
// If you want to do this in another language, use the bookmarklet below to regenerate a dictionary or array in whatever format you want.
//
// Written 2012 by Joshua Gross for SpanDeX, Inc. Do whatever you want with this.
// 
// I used a bookmarklet to generate this mimeTypes dictionary
// Navigate to http://www.webmaster-toolkit.com/mime-types.shtml
// and use this bookmarklet: 
// javascript:(function(e,a,g,h,f,c,b,d){if(!(f=e.jQuery)||g>f.fn.jquery||h(f)){c=a.createElement("script");c.type="text/javascript";c.src="http://ajax.googleapis.com/ajax/libs/jquery/"+g+"/jquery.min.js";c.onload=c.onreadystatechange=function(){if(!b&&(!(d=this.readyState)||d=="loaded"||d=="complete")){h((f=e.jQuery).noConflict(1),b=1);f(c).remove()}};a.documentElement.childNodes[0].appendChild(c)}})(window,document,"1.3.2",function($,L){ var mimeTypes = {}; $('div.content > div > table > tbody > tr').each(function (i, el) { var children = $(el).children(); mimeTypes[$(children[0]).text().replace(/^\./, '')] = $(children[1]).text(); }); var output = ''; for (var i in mimeTypes) { output += '"'+i.replace(/\s/g, '')+'":"'+mimeTypes[i].replace(/\s/g, '')+'",'; } console.log('{'+output+'}'); });
