test case

I have upload a test html page, use jscript to get value of
document.location.pathname.
if it was start with a leading slash, nothing will happen; if don't, will be a
alert.

this page was tested on IE8/11, Chrome, Firefox. they are all right.
but in builtin IE the value will do not have leading slash.
