"Unable to get property 'extend' of undefined or null reference" affecting to open the IE11

My local host (http://localhost:8080/) is working fine with Internet Explorer 11 (IE11) version. But context root (http://localhost:8080/context-root) is not working in IE11??

While opening the product through IE11 the http://localhost:8080/context-root, its not showing any page, it's simply showing blank page. In that there is showing below two errors
