how would I detect if "multiple" attribute is supported for file input elements?

file-upload, html, javascript, modernizr

Solution

var inp = document.createElement("input");
inp.setAttribute("multiple", "true");
var supportsMultiple = inp.multiple===true;

Problem

Internet Explorer does not support the `multiple` attribute for `<input type="file" />`. However, its not only IE that lacks this support... also certain mobile browsers do not support the `multiple` attribute. So simply detecting that the browser is IE is not the ideal solution. So how would I detect if the `multiple` attribute is supported for for `<input type="file" />` with JavaScript? UPDATE It seems like Modernizr has support for new HTML5 input element attributes: http://modernizr.com/docs/#input The accepted solution seems to work, however, since I'm already using Modernizr, my solution is the following: ``` /** * Determines if the given attribute is supported for <input /> elements. * * @param attribute - the attribute to test for (ex. "multiple") */ function isInputAttributeSupported(attribute) { return (Modernizr.input[attribute]) ? true : false; }; ```
