Date issue in Safari browser in iOS

The Safari browser in IOS5 and above (not including IOS5) correctly interprets the date object of the new date (' 2017-3-27 ') in JavaScript.

However, the IOS5 version of Safari explains that the new date (' 22017-3-27 ') is not correct, and the return in IOS5 Safari is always "Invalid date".

If you want safari in IOS5 to correctly parse the new Date () then it must be written

New Date (' 2017/3/27 ');

Or turn 2017-3-27 into a slash format,
var d = new Date (date);
D = d.getfullyear () > 0? D:new Date (Date.parse (Date.replace (/-/g, "/")));

(Back then to the back of the 2017-3-27 format, other browsers are all right, this is the thing)
