The File API isn't working in IE9

问题

I'm trying to get the file size and file type from an input field from my form using jQuery. I thought it was working however apparently not in IE 9. Any insight would be greatly appreciated

var my_field = this.files[0];

var myInteger = parseInt(my_field.size);

var myType = my_field.type;

That requires the File API, which isn't supported by IE9.

(And note that size is already a number [on browsers that support the File API], no need to parseInt it.)
