FileReader and JSON objects not defined in ie11
Whenever trying to open a page running a javascript code using FileReader and JSON upon page initialization, ie11 reports "FileReader is not defined", and later "JSON is not defined". The head of HTML file is as follows: <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>LogViewer</title> <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" /> <link rel="stylesheet" href="css/slick.grid.css" type="text/css"/> <link rel="stylesheet" type="text/css" href="css/style.css" /> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery
