A module that will validate different file types - I made it for image types but you can override them with an array of your file types

File Extension Validator

This is a js module that will validate file types that you feed it. I'm creating it to validate image file types for a node app, but you should be able to use it for whatever.

How it works

You feed the contructor a string of the filename and an array of file extensions you wish to validate on. Right now I'm using indexOf so it won't support < IE9.

• Working on a demo page
• Additional methods to validate common file types

How to use

<script src='js/fev.js'></script>

<script>
	(function(){
		var myFileCheck = new fileExtensionValidator({
		  file: 'unicorn-bike.bmp',
		  fileTypes: ['jpg','jpeg','png','gif','bmp']
		});

		var check = myFileCheck.validateExt();
		console.log(check); //true
	})();
</script>
