Input Gains Focus State Instead of Triggering Display about datepicker

@spencerfinnell I'll have to try it out with an iPhone. I'll let you know what I find.

I can confirm a similar problem. Works for my app on iphone 7s (ios11) but not on ipad (ios11). Also a problem on some Android devices eg. works OK on Samsung Galaxy 7 phone but not on Neos tablet. In my application (popup from icon rather than input element) the datepicker pop's up OK but unable to select either a date or the next/previous month buttons. Tried both chrome and native browser on Neos tablet with same result.

OK, I think I have found the problem. The datepicker code is written using the "new" javascript ES6 constructs. A lot of mobile devices out there do not support ES6. You can test for ES6 with the following snip:

    var supportsES6 = function() {
        try {
            new Function("(a = 0) => a");
            return true;
        }
        catch (err) {
            return false;
        }
    };
    alert("ES6 Support = "+supportsES6());

The only solution I can see is to develop a version using the ES5 standard.

@Lambo232 This library uses the minified datepicker.min.js file, which is all ES5. The issue is something different. I'm looking into it.

Ah-ha, that explains some of the the issues that I have been having, I assumed the the minified version was ES6 as well. To try to find my problem I was using the debug version and that is when I had the ES6 issues, damn, I have just spent a couple of hours converting it to ES5 so it would run on the problem devices.

Anyway I have found the "bug" that was causing my problem. I will submit it as a new issue.

I've pushed a fix to the master branch for iOS folks. Happy datepicking!
