如何为所有移动设备创建一个链接，打开谷歌地图，路线从当前位置开始，指定一个给定的地方？

Question

<a href="http://maps.google.com/maps?daddr=lat,long&amp;ll=">Take me there!</a>

谢谢

更新：找到解决方案（有点）

这是我想出来的。这和我想象的不太一样，尽管它起作用了。

var ua = navigator.userAgent.toLowerCase(),
    plat = navigator.platform,
    protocol = '',
    a,
    href;

$.browser.device = ua.match(/android|webos|iphone|ipad|ipod|blackberry|iemobile|opera/i) ? ua.match(/android|webos|iphone|ipad|ipod|blackberry|iemobile|opera/i)[0] : false;


if ($.browser.device) {
    switch($.browser.device) {
        case 'iphone':
        case 'ipad':
        case 'ipod':
            function iOSversion() {
              if (/iP(hone|od|ad)/.test(navigator.platform)) {
                // supports iOS 2.0 and later: <http://bit. ly/TJjs1V>
                var v = (navigator.appVersion).match(/OS (\d+)_(\d+)_?(\d+)?/);
                return [parseInt(v[1], 10), parseInt(v[2], 10), parseInt(v[3] || 0, 10)];
              }
            }

            var ver = iOSversion() || [0];

            if (ver[0] >= 6) {
              protocol = 'maps://';
            }
            else {
                protocol = 'http://maps.google.com/maps';
            }
        break;

        case 'android':
        default:
            protocol = 'http://maps.google.com/maps';
        break;
    }

a.attr('href', protocol + href)

可悲的是，$.browser.device从jQuery1.9起就不起作用了（源代码-http://api.jquery.com/jquery.browser）

<a style="cursor: pointer;" onclick="myNavFunc()">Take me there!</a>

function myNavFunc(){
    // If it's an iPhone..
    if( (navigator.platform.indexOf("iPhone") != -1) 
        || (navigator.platform.indexOf("iPod") != -1)
        || (navigator.platform.indexOf("iPad") != -1))
         window.open("maps://www.google.com/maps/dir/?api=1&travelmode=driving&layer=traffic&destination=[YOUR_LAT],[YOUR_LNG]");
    else
         window.open("https://www.google.com/maps/dir/?api=1&travelmode=driving&layer=traffic&destination=[YOUR_LAT],[YOUR_LNG]");
}
